The code is released under the MIT/X11, so feel free to modify and share your changes with the world. Read on below for how to get started. If you need any help using, the library, post your questions on [Stack Overflow] [stackoverflow] under the `appirater` tag. Getting Started --------------- ### CocoaPods To add Appirater to your app, add `pod "Appirater"` to your Podfile. Configuration ------------- 1. Appirater provides class methods to configure its behavior. See [`Appirater.h`] [Appirater.h] for more information. ```objc [Appirater setAppId:@"552035781"]; [Appirater setDaysUntilPrompt:1]; [Appirater setUsesUntilPrompt:10]; [Appirater setSignificantEventsUntilPrompt:-1]; [Appirater setTimeBeforeReminding:2]; [Appirater setDebug:YES]; ``` 2. Call `[Appirater setAppId:@"yourAppId"]` with the app id provided by Apple. A good place to do this is at the beginning of your app delegate's `application:didFinishLaunchingWithOptions:` method. 3. Call `[Appirater appLaunched:YES]` at the end of your app delegate's `application:didFinishLaunchingWithOptions:` method. 4. Call `[Appirater appEnteredForeground:YES]` in your app delegate's `applicationWillEnterForeground:` method. 5. (OPTIONAL) Call `[Appirater userDidSignificantEvent:YES]` when the user does something 'significant' in the app. ### Development Setting `[Appirater setDebug:YES]` will ensure that the rating request is shown each time the app is launched. ### Production Make sure you set `[Appirater setDebug:NO]` to ensure the request is not shown every time the app is launched. Also make sure that each of these components are set in the `application:didFinishLaunchingWithOptions:` method. This example states that the rating request is only shown when the app has been launched 5 times **and** after 7 days. ```objc [Appirater setAppId:@"770699556"]; [Appirater setDaysUntilPrompt:7]; [Appirater setUsesUntilPrompt:5]; [Appirater setSignificantEventsUntilPrompt:-1]; [Appirater setTimeBeforeReminding:2]; [Appirater setDebug:NO]; [Appirater appLaunched:YES]; ``` If you wanted to show the request after 5 days only you can set the following: ```objc [Appirater setAppId:@"770699556"]; [Appirater setDaysUntilPrompt:5]; [Appirater setUsesUntilPrompt:0]; [Appirater setSignificantEventsUntilPrompt:-1]; [Appirater setTimeBeforeReminding:2]; [Appirater setDebug:NO]; [Appirater appLaunched:YES]; ``` SKStoreReviewController ---------------------- In iOS 10.3, [SKStoreReviewController](https://developer.apple.com/library/content/releasenotes/General/WhatsNewIniOS/Articles/iOS10_3.html) was introduced which allows rating directly within the app without any additional setup. Appirater automatically uses `SKStoreReviewController` if available. You'll need to manually link `StoreKit` in your App however. If `SKStoreReviewController` is used, Appirater is used only to decide when to show the rating dialog to the user. Keep in mind, that `SKStoreReviewController` automatically limits the number of impressions, so the dialog might be displayed less frequently than your configured conditions might suggest. License ------- Copyright 2017. [Arash Payan] [arash]. This library is distributed under the terms of the MIT/X11. While not required, I greatly encourage and appreciate any improvements that you make to this library be contributed back for the benefit of all who use Appirater. Ports for other SDKs -------------- A few people have ported Appirater to other SDKs. The ports are listed here in hopes that they may assist developers of those SDKs. I don't know how closesly (if at all) they track the Objective-C version of Appirater. If you need support for any of the libraries, please contact the maintainer of the port. + MonoTouch Binding (using native Appirater).

Firebase is an app development platform with tools to help you build, grow and monetize your app. More information about Firebase can be found on the [official Firebase website](https://firebase.google.com). **Note** _FirebaseCombineSwift_ contains support for Apple's Combine framework. This module is currently under development, and not yet supported for use in production environments. Fore more details, please refer to the [docs](FirebaseCombineSwift/README.md). ## Installation See the subsections below for details about the different installation methods. 1. [Standard pod install](README.md#standard-pod-install) 1. [Swift Package Manager](SwiftPackageManager.md) 1. [Installing from the GitHub repo](README.md#installing-from-github) 1. [Experimental Carthage](README.md#carthage-ios-only) ### Standard pod install Go to [https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup). ### Swift Package Manager Instructions for [Swift Package Manager](https://swift.org/package-manager/) support can be found at [SwiftPackageManager.md](SwiftPackageManager.md). ### Installing from GitHub These instructions can be used to access the Firebase repo at other branches, tags, or commits. #### Background See [the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod) for instructions and options about overriding pod source locations. #### Accessing Firebase Source Snapshots All of the official releases are tagged in this repo and available via CocoaPods. To access a local source snapshot or unreleased branch, use Podfile directives like the following: To access FirebaseFirestore via a branch: ```ruby pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' ``` To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do: ```ruby pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk' pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk' ``` ### Carthage (iOS only) Instructions for the experimental Carthage distribution are at [Carthage](Carthage.md). ### Using Firebase from a Framework or a library [Using Firebase from a Framework or a library](docs/firebase_in_libraries.md) ## Development To develop Firebase software in this repository, ensure that you have at least the following software: * Xcode 12.2 (or later) CocoaPods is still the canonical way to develop, but much of the repo now supports development with Swift Package Manager. ### CocoaPods Install * CocoaPods 1.10.0 (or later) * [CocoaPods generate](https://github.com/square/cocoapods-generate) For the pod that you want to develop: ```ruby pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios ``` Note: If the CocoaPods cache is out of date, you may need to run `pod repo update` before the `pod gen` command. Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for those platforms. Since 10.2, Xcode does not properly handle multi-platform CocoaPods workspaces. Firestore has a self contained Xcode project. See [Firestore/README.md](Firestore/README.md). #### Development for Catalyst * `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios` * Check the Mac box in the App-iOS Build Settings * Sign the App in the Settings Signing & Capabilities tab * Click Pods in the Project Manager * Add Signing to the iOS host app and unit test targets * Select the Unit-unit scheme * Run it to build and test Alternatively disable signing in each target: * Go to Build Settings tab * Click `+` * Select `Add User-Defined Setting` * Add `CODE_SIGNING_REQUIRED` setting with a value of `NO` ### Swift Package Manager * To enable test schemes: `./scripts/setup_spm_tests.sh` * `open Package.swift` or double click `Package.swift` in Finder. * Xcode will open the project * Choose a scheme for a library to build or test suite to run * Choose a target platform by selecting the run destination along with the scheme ### Adding a New Firebase Pod See [AddNewPod.md](AddNewPod.md). ### Managing Headers and Imports See [HeadersImports.md](HeadersImports.md). ### Code Formatting To ensure that the code is formatted consistently, run the script [./scripts/check.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/check.sh) before creating a PR. GitHub Actions will verify that any code changes are done in a style compliant way. Install `clang-format` and `mint`: ```console brew install clang-format@12 brew install mint ``` ### Running Unit Tests Select a scheme and press Command-u to build a component and run its unit tests. ### Running Sample Apps In order to run the sample apps and integration tests, you'll need a valid `GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist files without real values, but can be replaced with real plist files. To get your own `GoogleService-Info.plist` files: 1. Go to the [Firebase Console](https://console.firebase.google.com/) 2. Create a new Firebase project, if you don't already have one 3. For each sample app you want to test, create a new Firebase app with the sample app's bundle identifier (e.g. `com.google.Database-Example`) 4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. ### Coverage Report Generation See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). ## Specific Component Instructions See the sections below for any special instructions for those components. ### Firebase Auth If you're doing specific Firebase Auth development, see [the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about building and running the FirebaseAuth pod along with various samples and tests. ### Firebase Database The Firebase Database Integration tests can be run against a locally running Database Emulator or against a production instance. To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before running the integration test. To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to `FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to [public](https://firebase.google.com/docs/database/security/quickstart) while your tests are running. ### Firebase Performance Monitoring If you're doing specific Firebase Performance Monitoring development, see [the Performance README](FirebasePerformance/README.md) for instructions about building the SDK and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about integrating Performance with the dev test App. ### Firebase Storage To run the Storage Integration tests, follow the instructions in [FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). #### Push Notifications Push notifications can only be delivered to specially provisioned App IDs in the developer portal. In order to actually test receiving push notifications, you will need to: 1. Change the bundle identifier of the sample app to something you own in your Apple Developer account, and enable that App ID for push notifications. 2. You'll also need to [upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) at **Project Settings > Cloud Messaging > [Your Firebase App]**. 3. Ensure your iOS device is added to your Apple Developer portal as a test device. #### iOS Simulator The iOS Simulator cannot register for remote notifications, and will not receive push notifications. In order to receive push notifications, you'll have to follow the steps above and run the app on a physical device. ## Building with Firebase on Apple platforms At this time, not all of Firebase's products are available across all Apple platforms. However, Firebase is constantly evolving and community supported efforts have helped expand Firebase's support. To keep up with the latest info regarding Firebase's support across Apple platforms, refer to [this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) in Firebase's documentation. ### Community Supported Efforts We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are very grateful! We'd like to empower as many developers as we can to be able to use Firebase and participate in the Firebase community. #### tvOS, macOS, watchOS and Catalyst Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on tvOS, macOS, watchOS and Catalyst. For tvOS, see the [Sample](Example/tvOSSample). For watchOS, currently only Messaging, Storage and Crashlytics (and their dependencies) have limited support. See the [Independent Watch App Sample](Example/watchOSSample). Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this repository is actively developed primarily for iOS. While we can catch basic unit test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues). During app setup in the console, you may get to a step that mentions something like "Checking if the app has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst. **It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. #### Additional MacOS and Catalyst Notes * FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability` to Build Settings. * For Catalyst, FirebaseFirestore requires signing the [gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681). #### Additional Crashlytics Notes * watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded) ## Roadmap See [Roadmap](ROADMAP.md) for more about the Firebase iOS SDK Open Source plans and directions. ## Contributing See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase iOS SDK. ## License The contents of this repository are licensed under the [Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0).

Firebase is an app development platform with tools to help you build, grow and monetize your app. More information about Firebase can be found on the [official Firebase website](https://firebase.google.com). **Note** _FirebaseCombineSwift_ contains support for Apple's Combine framework. This module is currently under development, and not yet supported for use in production environments. Fore more details, please refer to the [docs](FirebaseCombineSwift/README.md). ## Installation See the subsections below for details about the different installation methods. 1. [Standard pod install](README.md#standard-pod-install) 1. [Swift Package Manager](SwiftPackageManager.md) 1. [Installing from the GitHub repo](README.md#installing-from-github) 1. [Experimental Carthage](README.md#carthage-ios-only) ### Standard pod install Go to [https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup). ### Swift Package Manager Instructions for [Swift Package Manager](https://swift.org/package-manager/) support can be found at [SwiftPackageManager.md](SwiftPackageManager.md). ### Installing from GitHub These instructions can be used to access the Firebase repo at other branches, tags, or commits. #### Background See [the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod) for instructions and options about overriding pod source locations. #### Accessing Firebase Source Snapshots All of the official releases are tagged in this repo and available via CocoaPods. To access a local source snapshot or unreleased branch, use Podfile directives like the following: To access FirebaseFirestore via a branch: ```ruby pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' ``` To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do: ```ruby pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk' pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk' ``` ### Carthage (iOS only) Instructions for the experimental Carthage distribution are at [Carthage](Carthage.md). ### Using Firebase from a Framework or a library [Using Firebase from a Framework or a library](docs/firebase_in_libraries.md) ## Development To develop Firebase software in this repository, ensure that you have at least the following software: * Xcode 12.2 (or later) CocoaPods is still the canonical way to develop, but much of the repo now supports development with Swift Package Manager. ### CocoaPods Install * CocoaPods 1.10.0 (or later) * [CocoaPods generate](https://github.com/square/cocoapods-generate) For the pod that you want to develop: ```ruby pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios ``` Note: If the CocoaPods cache is out of date, you may need to run `pod repo update` before the `pod gen` command. Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for those platforms. Since 10.2, Xcode does not properly handle multi-platform CocoaPods workspaces. Firestore has a self contained Xcode project. See [Firestore/README.md](Firestore/README.md). #### Development for Catalyst * `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios` * Check the Mac box in the App-iOS Build Settings * Sign the App in the Settings Signing & Capabilities tab * Click Pods in the Project Manager * Add Signing to the iOS host app and unit test targets * Select the Unit-unit scheme * Run it to build and test Alternatively disable signing in each target: * Go to Build Settings tab * Click `+` * Select `Add User-Defined Setting` * Add `CODE_SIGNING_REQUIRED` setting with a value of `NO` ### Swift Package Manager * To enable test schemes: `./scripts/setup_spm_tests.sh` * `open Package.swift` or double click `Package.swift` in Finder. * Xcode will open the project * Choose a scheme for a library to build or test suite to run * Choose a target platform by selecting the run destination along with the scheme ### Adding a New Firebase Pod See [AddNewPod.md](AddNewPod.md). ### Managing Headers and Imports See [HeadersImports.md](HeadersImports.md). ### Code Formatting To ensure that the code is formatted consistently, run the script [./scripts/check.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/check.sh) before creating a PR. GitHub Actions will verify that any code changes are done in a style compliant way. Install `clang-format` and `mint`: ```console brew install clang-format@12 brew install mint ``` ### Running Unit Tests Select a scheme and press Command-u to build a component and run its unit tests. ### Running Sample Apps In order to run the sample apps and integration tests, you'll need a valid `GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist files without real values, but can be replaced with real plist files. To get your own `GoogleService-Info.plist` files: 1. Go to the [Firebase Console](https://console.firebase.google.com/) 2. Create a new Firebase project, if you don't already have one 3. For each sample app you want to test, create a new Firebase app with the sample app's bundle identifier (e.g. `com.google.Database-Example`) 4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. ### Coverage Report Generation See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). ## Specific Component Instructions See the sections below for any special instructions for those components. ### Firebase Auth If you're doing specific Firebase Auth development, see [the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about building and running the FirebaseAuth pod along with various samples and tests. ### Firebase Database The Firebase Database Integration tests can be run against a locally running Database Emulator or against a production instance. To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before running the integration test. To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to `FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to [public](https://firebase.google.com/docs/database/security/quickstart) while your tests are running. ### Firebase Performance Monitoring If you're doing specific Firebase Performance Monitoring development, see [the Performance README](FirebasePerformance/README.md) for instructions about building the SDK and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about integrating Performance with the dev test App. ### Firebase Storage To run the Storage Integration tests, follow the instructions in [FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). #### Push Notifications Push notifications can only be delivered to specially provisioned App IDs in the developer portal. In order to actually test receiving push notifications, you will need to: 1. Change the bundle identifier of the sample app to something you own in your Apple Developer account, and enable that App ID for push notifications. 2. You'll also need to [upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) at **Project Settings > Cloud Messaging > [Your Firebase App]**. 3. Ensure your iOS device is added to your Apple Developer portal as a test device. #### iOS Simulator The iOS Simulator cannot register for remote notifications, and will not receive push notifications. In order to receive push notifications, you'll have to follow the steps above and run the app on a physical device. ## Building with Firebase on Apple platforms At this time, not all of Firebase's products are available across all Apple platforms. However, Firebase is constantly evolving and community supported efforts have helped expand Firebase's support. To keep up with the latest info regarding Firebase's support across Apple platforms, refer to [this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) in Firebase's documentation. ### Community Supported Efforts We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are very grateful! We'd like to empower as many developers as we can to be able to use Firebase and participate in the Firebase community. #### tvOS, macOS, watchOS and Catalyst Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on tvOS, macOS, watchOS and Catalyst. For tvOS, see the [Sample](Example/tvOSSample). For watchOS, currently only Messaging, Storage and Crashlytics (and their dependencies) have limited support. See the [Independent Watch App Sample](Example/watchOSSample). Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this repository is actively developed primarily for iOS. While we can catch basic unit test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues). During app setup in the console, you may get to a step that mentions something like "Checking if the app has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst. **It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. #### Additional MacOS and Catalyst Notes * FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability` to Build Settings. * For Catalyst, FirebaseFirestore requires signing the [gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681). #### Additional Crashlytics Notes * watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded) ## Roadmap See [Roadmap](ROADMAP.md) for more about the Firebase iOS SDK Open Source plans and directions. ## Contributing See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase iOS SDK. ## License The contents of this repository are licensed under the [Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0).

Firebase is an app development platform with tools to help you build, grow and monetize your app. More information about Firebase can be found on the [official Firebase website](https://firebase.google.com). **Note** _FirebaseCombineSwift_ contains support for Apple's Combine framework. This module is currently under development, and not yet supported for use in production environments. Fore more details, please refer to the [docs](FirebaseCombineSwift/README.md). ## Installation See the subsections below for details about the different installation methods. 1. [Standard pod install](README.md#standard-pod-install) 1. [Swift Package Manager](SwiftPackageManager.md) 1. [Installing from the GitHub repo](README.md#installing-from-github) 1. [Experimental Carthage](README.md#carthage-ios-only) ### Standard pod install Go to [https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup). ### Swift Package Manager Instructions for [Swift Package Manager](https://swift.org/package-manager/) support can be found at [SwiftPackageManager.md](SwiftPackageManager.md). ### Installing from GitHub These instructions can be used to access the Firebase repo at other branches, tags, or commits. #### Background See [the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod) for instructions and options about overriding pod source locations. #### Accessing Firebase Source Snapshots All of the official releases are tagged in this repo and available via CocoaPods. To access a local source snapshot or unreleased branch, use Podfile directives like the following: To access FirebaseFirestore via a branch: ```ruby pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' ``` To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do: ```ruby pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk' pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk' ``` ### Carthage (iOS only) Instructions for the experimental Carthage distribution are at [Carthage](Carthage.md). ### Using Firebase from a Framework or a library [Using Firebase from a Framework or a library](docs/firebase_in_libraries.md) ## Development To develop Firebase software in this repository, ensure that you have at least the following software: * Xcode 12.2 (or later) CocoaPods is still the canonical way to develop, but much of the repo now supports development with Swift Package Manager. ### CocoaPods Install * CocoaPods 1.10.0 (or later) * [CocoaPods generate](https://github.com/square/cocoapods-generate) For the pod that you want to develop: ```ruby pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios ``` Note: If the CocoaPods cache is out of date, you may need to run `pod repo update` before the `pod gen` command. Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for those platforms. Since 10.2, Xcode does not properly handle multi-platform CocoaPods workspaces. Firestore has a self contained Xcode project. See [Firestore/README.md](Firestore/README.md). #### Development for Catalyst * `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios` * Check the Mac box in the App-iOS Build Settings * Sign the App in the Settings Signing & Capabilities tab * Click Pods in the Project Manager * Add Signing to the iOS host app and unit test targets * Select the Unit-unit scheme * Run it to build and test Alternatively disable signing in each target: * Go to Build Settings tab * Click `+` * Select `Add User-Defined Setting` * Add `CODE_SIGNING_REQUIRED` setting with a value of `NO` ### Swift Package Manager * To enable test schemes: `./scripts/setup_spm_tests.sh` * `open Package.swift` or double click `Package.swift` in Finder. * Xcode will open the project * Choose a scheme for a library to build or test suite to run * Choose a target platform by selecting the run destination along with the scheme ### Adding a New Firebase Pod See [AddNewPod.md](AddNewPod.md). ### Managing Headers and Imports See [HeadersImports.md](HeadersImports.md). ### Code Formatting To ensure that the code is formatted consistently, run the script [./scripts/check.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/check.sh) before creating a PR. GitHub Actions will verify that any code changes are done in a style compliant way. Install `clang-format` and `mint`: ```console brew install clang-format@12 brew install mint ``` ### Running Unit Tests Select a scheme and press Command-u to build a component and run its unit tests. ### Running Sample Apps In order to run the sample apps and integration tests, you'll need a valid `GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist files without real values, but can be replaced with real plist files. To get your own `GoogleService-Info.plist` files: 1. Go to the [Firebase Console](https://console.firebase.google.com/) 2. Create a new Firebase project, if you don't already have one 3. For each sample app you want to test, create a new Firebase app with the sample app's bundle identifier (e.g. `com.google.Database-Example`) 4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. ### Coverage Report Generation See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). ## Specific Component Instructions See the sections below for any special instructions for those components. ### Firebase Auth If you're doing specific Firebase Auth development, see [the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about building and running the FirebaseAuth pod along with various samples and tests. ### Firebase Database The Firebase Database Integration tests can be run against a locally running Database Emulator or against a production instance. To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before running the integration test. To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to `FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to [public](https://firebase.google.com/docs/database/security/quickstart) while your tests are running. ### Firebase Performance Monitoring If you're doing specific Firebase Performance Monitoring development, see [the Performance README](FirebasePerformance/README.md) for instructions about building the SDK and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about integrating Performance with the dev test App. ### Firebase Storage To run the Storage Integration tests, follow the instructions in [FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). #### Push Notifications Push notifications can only be delivered to specially provisioned App IDs in the developer portal. In order to actually test receiving push notifications, you will need to: 1. Change the bundle identifier of the sample app to something you own in your Apple Developer account, and enable that App ID for push notifications. 2. You'll also need to [upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) at **Project Settings > Cloud Messaging > [Your Firebase App]**. 3. Ensure your iOS device is added to your Apple Developer portal as a test device. #### iOS Simulator The iOS Simulator cannot register for remote notifications, and will not receive push notifications. In order to receive push notifications, you'll have to follow the steps above and run the app on a physical device. ## Building with Firebase on Apple platforms At this time, not all of Firebase's products are available across all Apple platforms. However, Firebase is constantly evolving and community supported efforts have helped expand Firebase's support. To keep up with the latest info regarding Firebase's support across Apple platforms, refer to [this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) in Firebase's documentation. ### Community Supported Efforts We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are very grateful! We'd like to empower as many developers as we can to be able to use Firebase and participate in the Firebase community. #### tvOS, macOS, watchOS and Catalyst Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on tvOS, macOS, watchOS and Catalyst. For tvOS, see the [Sample](Example/tvOSSample). For watchOS, currently only Messaging, Storage and Crashlytics (and their dependencies) have limited support. See the [Independent Watch App Sample](Example/watchOSSample). Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this repository is actively developed primarily for iOS. While we can catch basic unit test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues). During app setup in the console, you may get to a step that mentions something like "Checking if the app has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst. **It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. #### Additional MacOS and Catalyst Notes * FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability` to Build Settings. * For Catalyst, FirebaseFirestore requires signing the [gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681). #### Additional Crashlytics Notes * watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded) ## Roadmap See [Roadmap](ROADMAP.md) for more about the Firebase iOS SDK Open Source plans and directions. ## Contributing See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase iOS SDK. ## License The contents of this repository are licensed under the [Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0).

Firebase is an app development platform with tools to help you build, grow and monetize your app. More information about Firebase can be found on the [official Firebase website](https://firebase.google.com). **Note** _FirebaseCombineSwift_ contains support for Apple's Combine framework. This module is currently under development, and not yet supported for use in production environments. Fore more details, please refer to the [docs](FirebaseCombineSwift/README.md). ## Installation See the subsections below for details about the different installation methods. 1. [Standard pod install](README.md#standard-pod-install) 1. [Swift Package Manager](SwiftPackageManager.md) 1. [Installing from the GitHub repo](README.md#installing-from-github) 1. [Experimental Carthage](README.md#carthage-ios-only) ### Standard pod install Go to [https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup). ### Swift Package Manager Instructions for [Swift Package Manager](https://swift.org/package-manager/) support can be found at [SwiftPackageManager.md](SwiftPackageManager.md). ### Installing from GitHub These instructions can be used to access the Firebase repo at other branches, tags, or commits. #### Background See [the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod) for instructions and options about overriding pod source locations. #### Accessing Firebase Source Snapshots All of the official releases are tagged in this repo and available via CocoaPods. To access a local source snapshot or unreleased branch, use Podfile directives like the following: To access FirebaseFirestore via a branch: ```ruby pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' ``` To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do: ```ruby pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk' pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk' ``` ### Carthage (iOS only) Instructions for the experimental Carthage distribution are at [Carthage](Carthage.md). ### Using Firebase from a Framework or a library [Using Firebase from a Framework or a library](docs/firebase_in_libraries.md) ## Development To develop Firebase software in this repository, ensure that you have at least the following software: * Xcode 12.2 (or later) CocoaPods is still the canonical way to develop, but much of the repo now supports development with Swift Package Manager. ### CocoaPods Install * CocoaPods 1.10.0 (or later) * [CocoaPods generate](https://github.com/square/cocoapods-generate) For the pod that you want to develop: ```ruby pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios ``` Note: If the CocoaPods cache is out of date, you may need to run `pod repo update` before the `pod gen` command. Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for those platforms. Since 10.2, Xcode does not properly handle multi-platform CocoaPods workspaces. Firestore has a self contained Xcode project. See [Firestore/README.md](Firestore/README.md). #### Development for Catalyst * `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios` * Check the Mac box in the App-iOS Build Settings * Sign the App in the Settings Signing & Capabilities tab * Click Pods in the Project Manager * Add Signing to the iOS host app and unit test targets * Select the Unit-unit scheme * Run it to build and test Alternatively disable signing in each target: * Go to Build Settings tab * Click `+` * Select `Add User-Defined Setting` * Add `CODE_SIGNING_REQUIRED` setting with a value of `NO` ### Swift Package Manager * To enable test schemes: `./scripts/setup_spm_tests.sh` * `open Package.swift` or double click `Package.swift` in Finder. * Xcode will open the project * Choose a scheme for a library to build or test suite to run * Choose a target platform by selecting the run destination along with the scheme ### Adding a New Firebase Pod See [AddNewPod.md](AddNewPod.md). ### Managing Headers and Imports See [HeadersImports.md](HeadersImports.md). ### Code Formatting To ensure that the code is formatted consistently, run the script [./scripts/check.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/check.sh) before creating a PR. GitHub Actions will verify that any code changes are done in a style compliant way. Install `clang-format` and `mint`: ```console brew install clang-format@12 brew install mint ``` ### Running Unit Tests Select a scheme and press Command-u to build a component and run its unit tests. ### Running Sample Apps In order to run the sample apps and integration tests, you'll need a valid `GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist files without real values, but can be replaced with real plist files. To get your own `GoogleService-Info.plist` files: 1. Go to the [Firebase Console](https://console.firebase.google.com/) 2. Create a new Firebase project, if you don't already have one 3. For each sample app you want to test, create a new Firebase app with the sample app's bundle identifier (e.g. `com.google.Database-Example`) 4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. ### Coverage Report Generation See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). ## Specific Component Instructions See the sections below for any special instructions for those components. ### Firebase Auth If you're doing specific Firebase Auth development, see [the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about building and running the FirebaseAuth pod along with various samples and tests. ### Firebase Database The Firebase Database Integration tests can be run against a locally running Database Emulator or against a production instance. To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before running the integration test. To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to `FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to [public](https://firebase.google.com/docs/database/security/quickstart) while your tests are running. ### Firebase Performance Monitoring If you're doing specific Firebase Performance Monitoring development, see [the Performance README](FirebasePerformance/README.md) for instructions about building the SDK and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about integrating Performance with the dev test App. ### Firebase Storage To run the Storage Integration tests, follow the instructions in [FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). #### Push Notifications Push notifications can only be delivered to specially provisioned App IDs in the developer portal. In order to actually test receiving push notifications, you will need to: 1. Change the bundle identifier of the sample app to something you own in your Apple Developer account, and enable that App ID for push notifications. 2. You'll also need to [upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) at **Project Settings > Cloud Messaging > [Your Firebase App]**. 3. Ensure your iOS device is added to your Apple Developer portal as a test device. #### iOS Simulator The iOS Simulator cannot register for remote notifications, and will not receive push notifications. In order to receive push notifications, you'll have to follow the steps above and run the app on a physical device. ## Building with Firebase on Apple platforms At this time, not all of Firebase's products are available across all Apple platforms. However, Firebase is constantly evolving and community supported efforts have helped expand Firebase's support. To keep up with the latest info regarding Firebase's support across Apple platforms, refer to [this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) in Firebase's documentation. ### Community Supported Efforts We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are very grateful! We'd like to empower as many developers as we can to be able to use Firebase and participate in the Firebase community. #### tvOS, macOS, watchOS and Catalyst Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on tvOS, macOS, watchOS and Catalyst. For tvOS, see the [Sample](Example/tvOSSample). For watchOS, currently only Messaging, Storage and Crashlytics (and their dependencies) have limited support. See the [Independent Watch App Sample](Example/watchOSSample). Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this repository is actively developed primarily for iOS. While we can catch basic unit test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues). During app setup in the console, you may get to a step that mentions something like "Checking if the app has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst. **It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. #### Additional MacOS and Catalyst Notes * FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability` to Build Settings. * For Catalyst, FirebaseFirestore requires signing the [gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681). #### Additional Crashlytics Notes * watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded) ## Roadmap See [Roadmap](ROADMAP.md) for more about the Firebase iOS SDK Open Source plans and directions. ## Contributing See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase iOS SDK. ## License The contents of this repository are licensed under the [Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0).

It allows the logging of data and telemetry from Google SDKs. ## Integration Testing These instructions apply to minor and patch version updates. Major versions need a customized adaptation. After the CI is green: * Determine the next version for release by checking the [tagged releases](https://github.com/google/GoogleDataTransport/tags). Ensure that the next release version keeps the Swift PM and CocoaPods versions in sync. * Verify that the releasing version is the latest entry in the [CHANGELOG.md](CHANGELOG.md), updating it if necessary. * Update the version in the podspec to match the latest entry in the [CHANGELOG.md](CHANGELOG.md) * Checkout the `main` branch and ensure it is up to date. ```console git checkout main git pull ``` * Add the CocoaPods tag (`{version}` will be the latest version in the [podspec](GoogleDataTransport.podspec#L3)) ```console git tag CocoaPods-{version} git push origin CocoaPods-{version} ``` * Push the podspec to the designated repo * If this version of GDT is intended to launch **before or with** the next Firebase release:
Push to SpecsStaging ```console pod repo push --skip-tests staging GoogleDataTransport.podspec ``` If the command fails with `Unable to find the 'staging' repo.`, add the staging repo with: ```console pod repo add staging git@github.com:firebase/SpecsStaging.git ```
* Otherwise:
Push to SpecsDev ```console pod repo push --skip-tests dev GoogleDataTransport.podspec ``` If the command fails with `Unable to find the 'dev' repo.`, add the dev repo with: ```console pod repo add dev git@github.com:firebase/SpecsDev.git ```
* Run Firebase CI by waiting until next nightly or adding a PR that touches `Gemfile`. * On google3, create a workspace and new CL. Then copybara and run a global TAP.

## Publishing The release process is as follows: 1. [Tag and release for Swift PM](#swift-package-manager) 2. [Publish to CocoaPods](#cocoapods) 3. [Create GitHub Release](#create-github-release) 4. [Perform post release cleanup](#post-release-cleanup) ### Swift Package Manager By creating and [pushing a tag](https://github.com/google/GoogleDataTransport/tags) for Swift PM, the newly tagged version will be immediately released for public use. Given this, please verify the intended time of release for Swift PM. * Add a version tag for Swift PM ```console git tag {version} git push origin {version} ``` *Note: Ensure that any inflight PRs that depend on the new `GoogleDataTransport` version are updated to point to the newly tagged version rather than a checksum.* ### CocoaPods * Publish the newly versioned pod to CocoaPods It's recommended to point to the `GoogleDataTransport.podspec` in `staging` to make sure the correct spec is being published. ```console pod trunk push ~/.cocoapods/repos/staging/GoogleDataTransport.podspec --skip-tests ``` The pod push was successful if the above command logs: `🚀 GoogleDataTransport ({version}) successfully published`. In addition, a new commit that publishes the new version (co-authored by [CocoaPodsAtGoogle](https://github.com/CocoaPodsAtGoogle)) should appear in the [CocoaPods specs repo](https://github.com/CocoaPods/Specs). Last, the latest version should be displayed on [GoogleDataTransport's CocoaPods page](https://cocoapods.org/pods/GoogleDataTransport). ### [Create GitHub Release](https://github.com/google/GoogleDataTransport/releases/new/) Update the [release template](https://github.com/google/GoogleDataTransport/releases/new/)'s **Tag version** and **Release title** fields with the latest version. In addition, reference the [Release Notes](./CHANGELOG.md) in the release's description. See [this release](https://github.com/google/GoogleDataTransport/releases/edit/9.0.1) for an example. *Don't forget to perform the [post release cleanup](#post-release-cleanup)!* ### Post Release Cleanup
Clean up SpecsStaging ```console pwd=$(pwd) mkdir -p /tmp/release-cleanup && cd $_ git clone git@github.com:firebase/SpecsStaging.git cd SpecsStaging/ git rm -rf GoogleDataTransport/ git commit -m "Post publish cleanup" git push origin master rm -rf /tmp/release-cleanup cd $pwd ```
## Set logging level ### Swift - Import `GoogleDataTransport` module: ```swift import GoogleDataTransport ``` - Set logging level global variable to the desired value before calling `FirebaseApp.configure()`: ```swift GDTCORConsoleLoggerLoggingLevel = GDTCORLoggingLevel.debug.rawValue ``` ### Objective-C - Import `GoogleDataTransport`: ```objective-c #import ``` - Set logging level global variable to the desired value before calling `-[FIRApp configure]`: ```objective-c GDTCORConsoleLoggerLoggingLevel = GDTCORLoggingLevelDebug; ``` ## Prereqs - `gem install --user cocoapods cocoapods-generate` - `brew install protobuf nanopb-generator` - `easy_install --user protobuf` ## To develop - Run `./GoogleDataTransport/generate_project.sh` after installing the prereqs ## When adding new logging endpoint - Use commands similar to: - `python -c "line='https://www.firebase.com'; print line[0::2]" ` - `python -c "line='https://www.firebase.com'; print line[1::2]" ` ## When adding internal code that shouldn't be easily usable on github - Consider using go/copybara-library/scrubbing#cc_scrub ## Development Ensure that you have at least the following software: * Xcode 12.0 (or later) * CocoaPods 1.10.0 (or later) * [CocoaPods generate](https://github.com/square/cocoapods-generate) For the pod that you want to develop: `pod gen GoogleDataTransport.podspec --local-sources=./ --auto-open --platforms=ios` Note: If the CocoaPods cache is out of date, you may need to run `pod repo update` before the `pod gen` command. Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for those platforms. Since 10.2, Xcode does not properly handle multi-platform CocoaPods workspaces. ### Development for Catalyst * `pod gen GoogleDataTransport.podspec --local-sources=./ --auto-open --platforms=ios` * Check the Mac box in the App-iOS Build Settings * Sign the App in the Settings Signing & Capabilities tab * Click Pods in the Project Manager * Add Signing to the iOS host app and unit test targets * Select the Unit-unit scheme * Run it to build and test Alternatively disable signing in each target: * Go to Build Settings tab * Click `+` * Select `Add User-Defined Setting` * Add `CODE_SIGNING_REQUIRED` setting with a value of `NO` ### Code Formatting To ensure that the code is formatted consistently, run the script [./scripts/check.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/check.sh) before creating a PR. GitHub Actions will verify that any code changes are done in a style compliant way. Install `clang-format` and `mint`: ```console brew install clang-format@12 brew install mint ``` ### Running Unit Tests Select a scheme and press Command-u to build a component and run its unit tests. ## Contributing See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase iOS SDK. ## License The contents of this repository is licensed under the [Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0).

Comment from iPhone Dev Wiki Crack Prevention: App Store binaries are signed by both their developer and Apple. This encrypts the binary so that decryption keys are needed in order to make the binary readable. When iOS executes the binary, the decryption keys are used to decrypt the binary into a readable state where it is then loaded into memory and executed. iOS can tell the encryption status of a binary via the cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is a non-zero value then the binary is encrypted. 'Cracking' works by letting the kernel decrypt the binary then siphoning the decrypted data into a new binary file, resigning, and repackaging. This will only work on jailbroken devices as codesignature validation has been removed. Resigning takes place because while the codesignature doesn't have to be valid thanks to the jailbreak, it does have to be in place unless you have AppSync or similar to disable codesignature checks.

The utilities are not directly supported for non-Google library usage. ## Integration Testing These instructions apply to minor and patch version updates. Major versions need a customized adaptation. After the CI is green: * Determine the next version for release by checking the [tagged releases](https://github.com/google/GoogleUtilities/tags). Ensure that the next release version keeps the Swift PM and CocoaPods versions in sync. * Verify that the releasing version is the latest entry in the [CHANGELOG.md](CHANGELOG.md), updating it if necessary. * Update the version in the podspec to match the latest entry in the [CHANGELOG.md](CHANGELOG.md) * Checkout the `main` branch and ensure it is up to date ```console git checkout main git pull ``` * Add the CocoaPods tag (`{version}` will be the latest version in the [podspec](GoogleUtilities.podspec#L3)) ```console git tag CocoaPods-{version} git push origin CocoaPods-{version} ``` * Push the podspec to the designated repo * If this version of GoogleUtilities is intended to launch **before or with** the next Firebase release:
Push to SpecsStaging ```console pod repo push --skip-tests staging GoogleUtilities.podspec ``` If the command fails with `Unable to find the 'staging' repo.`, add the staging repo with: ```console pod repo add staging git@github.com:firebase/SpecsStaging.git ```
* Otherwise:
Push to SpecsDev ```console pod repo push --skip-tests dev GoogleUtilities.podspec ``` If the command fails with `Unable to find the 'dev' repo.`, add the dev repo with: ```console pod repo add dev git@github.com:firebase/SpecsDev.git ```
* Run Firebase CI by waiting until next nightly or adding a PR that touches `Gemfile`. * On google3, run copybara using the command below. Then, start a global TAP on the generated CL. Deflake as needed. ```console third_party/firebase/ios/Releases/run_copy_bara.py --directory GoogleUtilities --branch main ``` ## Publishing The release process is as follows: 1. [Tag and release for Swift PM](#swift-package-manager) 2. [Publish to CocoaPods](#cocoapods) 3. [Create GitHub Release](#create-github-release) 4. [Perform post release cleanup](#post-release-cleanup) ### Swift Package Manager By creating and [pushing a tag](https://github.com/google/GoogleUtilities/tags) for Swift PM, the newly tagged version will be immediately released for public use. Given this, please verify the intended time of release for Swift PM. * Add a version tag for Swift PM ```console git tag {version} git push origin {version} ``` *Note: Ensure that any inflight PRs that depend on the new `GoogleUtilities` version are updated to point to the newly tagged version rather than a checksum.* ### CocoaPods * Publish the newly versioned pod to CocoaPods It's recommended to point to the `GoogleUtilities.podspec` in `staging` to make sure the correct spec is being published. ```console pod trunk push ~/.cocoapods/repos/staging/GoogleUtilities/{version}/GoogleUtilities.podspec ``` *Note: In some cases, it may be acceptable to `pod trunk push` with the `--skip-tests` flag. Please double check with the maintainers before doing so.* The pod push was successful if the above command logs: `🚀 GoogleUtilities ({version}) successfully published`. In addition, a new commit that publishes the new version (co-authored by [CocoaPodsAtGoogle](https://github.com/CocoaPodsAtGoogle)) should appear in the [CocoaPods specs repo](https://github.com/CocoaPods/Specs). Last, the latest version should be displayed on [GoogleUtilities's CocoaPods page](https://cocoapods.org/pods/GoogleUtilities). ### [Create GitHub Release](https://github.com/google/GoogleUtilities/releases/new/) Update the [release template](https://github.com/google/GoogleUtilities/releases/new/)'s **Tag version** and **Release title** fields with the latest version. In addition, reference the [Release Notes](./CHANGELOG.md) in the release's description. See [this release](https://github.com/google/GoogleUtilities/releases/edit/9.0.1) for an example. *Don't forget to perform the [post release cleanup](#post-release-cleanup)!* ### Post Release Cleanup
Clean up SpecsStaging ```console pwd=$(pwd) mkdir -p /tmp/release-cleanup && cd $_ git clone git@github.com:firebase/SpecsStaging.git cd SpecsStaging/ git rm -rf GoogleUtilities/ git commit -m "Post publish cleanup" git push origin master rm -rf /tmp/release-cleanup cd $pwd ```
## Development To develop in this repository, ensure that you have at least the following software: * Xcode 12.0 (or later) * CocoaPods 1.10.0 (or later) * [CocoaPods generate](https://github.com/square/cocoapods-generate) For the pod that you want to develop: `pod gen GoogleUtilities.podspec --local-sources=./ --auto-open --platforms=ios` Note: If the CocoaPods cache is out of date, you may need to run `pod repo update` before the `pod gen` command. Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for those platforms. Since 10.2, Xcode does not properly handle multi-platform CocoaPods workspaces. ### Development for Catalyst * `pod gen GoogleUtilities.podspec --local-sources=./ --auto-open --platforms=ios` * Check the Mac box in the App-iOS Build Settings * Sign the App in the Settings Signing & Capabilities tab * Click Pods in the Project Manager * Add Signing to the iOS host app and unit test targets * Select the Unit-unit scheme * Run it to build and test Alternatively disable signing in each target: * Go to Build Settings tab * Click `+` * Select `Add User-Defined Setting` * Add `CODE_SIGNING_REQUIRED` setting with a value of `NO` ### Code Formatting To ensure that the code is formatted consistently, run the script [./scripts/check.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/check.sh) before creating a PR. GitHub Actions will verify that any code changes are done in a style compliant way. Install `clang-format` and `mint`: ```console brew install clang-format@12 brew install mint ``` ### Running Unit Tests Select a scheme and press Command-u to build a component and run its unit tests. ## Contributing See [Contributing](CONTRIBUTING.md). ## License The contents of this repository is licensed under the [Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0).

See all the list in [Image coder plugin List](https://github.com/SDWebImage/SDWebImage/wiki/Coder-Plugin-List) ## Additional modules and Ecosystem In order to keep SDWebImage focused and limited to the core features, but also allow extensibility and custom behaviors, during the 5.0 refactoring we focused on modularizing the library. As such, we have moved/built new modules to [SDWebImage org](https://github.com/SDWebImage). #### SwiftUI [SwiftUI](https://developer.apple.com/xcode/swiftui/) is an innovative UI framework written in Swift to build user interfaces across all Apple platforms. We support SwiftUI by building a brand new framework called [SDWebImageSwiftUI](https://github.com/SDWebImage/SDWebImageSwiftUI), which is built on top of SDWebImage core functions (caching, loading and animation). The new framework introduce two View structs `WebImage` and `AnimatedImage` for SwiftUI world, `ImageIndicator` modifier for any View, `ImageManager` observable object for data source. Supports iOS 13+/macOS 10.15+/tvOS 13+/watchOS 6+ and Swift 5.1.

[imageView sd_setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"] placeholderImage:[UIImage imageNamed:@"placeholder.png"]]; ``` * Swift ```swift import SDWebImage imageView.sd_setImage(with: URL(string: "http://www.domain.com/path/to/image.jpg"), placeholderImage: UIImage(named: "placeholder.png")) ``` - For details about how to use the library and clear examples, see [The detailed How to use](https://github.com/SDWebImage/SDWebImage/blob/master/Docs/HowToUse.md) ## Animated Images (GIF) support In 5.0, we introduced a brand new mechanism for supporting animated images. This includes animated image loading, rendering, decoding, and also supports customizations (for advanced users). This animated image solution is available for `iOS`/`tvOS`/`macOS`. The `SDAnimatedImage` is subclass of `UIImage/NSImage`, and `SDAnimatedImageView` is subclass of `UIImageView/NSImageView`, to make them compatible with the common frameworks APIs. The `SDAnimatedImageView` supports the familiar image loading category methods, works like drop-in replacement for `UIImageView/NSImageView`. Don't have `UIView` (like `WatchKit` or `CALayer`)? you can still use `SDAnimatedPlayer` the player engine for advanced playback and rendering. See [Animated Image](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#animated-image-50) for more detailed information. * Objective-C ```objective-c SDAnimatedImageView *imageView = [SDAnimatedImageView new]; SDAnimatedImage *animatedImage = [SDAnimatedImage imageNamed:@"image.gif"]; imageView.image = animatedImage; ``` * Swift ```swift let imageView = SDAnimatedImageView() let animatedImage = SDAnimatedImage(named: "image.gif") imageView.image = animatedImage ``` #### FLAnimatedImage integration has its own dedicated repo In order to clean up things and make our core project do less things, we decided that the `FLAnimatedImage` integration does not belong here. From 5.0, this will still be available, but under a dedicated repo [SDWebImageFLPlugin](https://github.com/SDWebImage/SDWebImageFLPlugin). ## Installation There are four ways to use SDWebImage in your project: - using CocoaPods - using Carthage - using Swift Package Manager - manual install (build frameworks or embed Xcode Project) ### Installation with CocoaPods [CocoaPods](http://cocoapods.org/) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. See the [Get Started](http://cocoapods.org/#get_started) section for more details. #### Podfile ``` platform :ios, '8.0' pod 'SDWebImage', '~> 5.0' ``` ##### Swift and static framework Swift project previously had to use `use_frameworks!` to make all Pods into dynamic framework to let CocoaPods work. However, starting with `CocoaPods 1.5.0+` (with `Xcode 9+`), which supports to build both Objective-C && Swift code into static framework. You can use modular headers to use SDWebImage as static framework, without the need of `use_frameworks!`: ``` platform :ios, '8.0' # Uncomment the next line when you want all Pods as static framework # use_modular_headers! pod 'SDWebImage', :modular_headers => true ``` See more on [CocoaPods 1.5.0 — Swift Static Libraries](http://blog.cocoapods.org/CocoaPods-1.5.0/) If not, you still need to add `use_frameworks!` to use SDWebImage as dynamic framework: ``` platform :ios, '8.0' use_frameworks! pod 'SDWebImage' ``` #### Subspecs There are 2 subspecs available now: `Core` and `MapKit` (this means you can install only some of the SDWebImage modules. By default, you get just `Core`, so if you need `MapKit`, you need to specify it). Podfile example: ``` pod 'SDWebImage/MapKit' ``` ### Installation with Carthage [Carthage](https://github.com/Carthage/Carthage) is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods. To install with carthage, follow the instruction on [Carthage](https://github.com/Carthage/Carthage) Carthage users can point to this repository and use whichever generated framework they'd like: SDWebImage, SDWebImageMapKit or both. Make the following entry in your Cartfile: `github "SDWebImage/SDWebImage"` Then run `carthage update` If this is your first time using Carthage in the project, you'll need to go through some additional steps as explained [over at Carthage](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application). > NOTE: At this time, Carthage does not provide a way to build only specific repository subcomponents (or equivalent of CocoaPods's subspecs). All components and their dependencies will be built with the above command. However, you don't need to copy frameworks you aren't using into your project. For instance, if you aren't using `SDWebImageMapKit`, feel free to delete that framework from the Carthage Build directory after `carthage update` completes. ### Installation with Swift Package Manager (Xcode 11+) [Swift Package Manager](https://swift.org/package-manager/) (SwiftPM) is a tool for managing the distribution of Swift code as well as C-family dependency. From Xcode 11, SwiftPM got natively integrated with Xcode. SDWebImage support SwiftPM from version 5.1.0. To use SwiftPM, you should use Xcode 11 to open your project. Click `File` -> `Swift Packages` -> `Add Package Dependency`, enter [SDWebImage repo's URL](https://github.com/SDWebImage/SDWebImage.git). Or you can login Xcode with your GitHub account and just type `SDWebImage` to search. After select the package, you can choose the dependency type (tagged version, branch or commit). Then Xcode will setup all the stuff for you. If you're a framework author and use SDWebImage as a dependency, update your `Package.swift` file: ```swift let package = Package( // 5.1.0 ..< 6.0.0 dependencies: [ .package(url: "https://github.com/SDWebImage/SDWebImage.git", from: "5.1.0") ], // ... ) ``` ### Manual Installation Guide See more on [Manual install Guide](https://github.com/SDWebImage/SDWebImage/wiki/Installation-Guide#manual-installation-guide) ### Import headers in your source files In the source files where you need to use the library, import the umbrella header file: ```objective-c #import ``` It's also recommend to use the module import syntax, available for CocoaPods(enable `modular_headers`)/Carthage/SwiftPM. ```objecitivec @import SDWebImage; ``` ### Build Project At this point your workspace should build without error. If you are having problem, post to the Issue and the community can help you solve it. ## Data Collection Practices As required by the [App privacy details on the App Store](https://developer.apple.com/app-store/app-privacy-details/), here's SDWebImage's list of [Data Collection Practices](https://sdwebimage.github.io/DataCollection/index.html). ## Author - [Olivier Poitrey](https://github.com/rs) ## Collaborators - [Konstantinos K.](https://github.com/mythodeia) - [Bogdan Poplauschi](https://github.com/bpoplauschi) - [Chester Liu](https://github.com/skyline75489) - [DreamPiggy](https://github.com/dreampiggy) - [Wu Zhong](https://github.com/zhongwuzw) ## Credits Thank you to all the people who have already contributed to SDWebImage.

Comment from iPhone Dev Wiki Crack Prevention: App Store binaries are signed by both their developer and Apple. This encrypts the binary so that decryption keys are needed in order to make the binary readable. When iOS executes the binary, the decryption keys are used to decrypt the binary into a readable state where it is then loaded into memory and executed. iOS can tell the encryption status of a binary via the cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is a non-zero value then the binary is encrypted. 'Cracking' works by letting the kernel decrypt the binary then siphoning the decrypted data into a new binary file, resigning, and repackaging. This will only work on jailbroken devices as codesignature validation has been removed. Resigning takes place because while the codesignature doesn't have to be valid thanks to the jailbreak, it does have to be in place unless you have AppSync or similar to disable codesignature checks.

Comment from <a href="http://iphonedevwiki.net/index.php/Crack_prevention">iPhone Dev Wiki Crack Prevention</a>: App Store binaries are signed by both their developer and Apple. This encrypts the binary so that decryption keys are needed in order to make the binary readable. When iOS executes the binary, the decryption keys are used to decrypt the binary into a readable state where it is then loaded into memory and executed. iOS can tell the encryption status of a binary via the cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is a non-zero value then the binary is encrypted. 'Cracking' works by letting the kernel decrypt the binary then siphoning the decrypted data into a new binary file, resigning, and repackaging. This will only work on jailbroken devices as codesignature validation has been removed. Resigning takes place because while the codesignature doesn't have to be valid thanks to the jailbreak, it does have to be in place unless you have AppSync or similar to disable codesignature checks.

It is especially suitable for use in microcontrollers, but fits any memory restricted system. * **Homepage:** https://jpa.kapsi.fi/nanopb/ * **Documentation:** https://jpa.kapsi.fi/nanopb/docs/ * **Downloads:** https://jpa.kapsi.fi/nanopb/download/ * **Forum:** https://groups.google.com/forum/#!forum/nanopb Using the nanopb library ------------------------ To use the nanopb library, you need to do two things: 1. Compile your .proto files for nanopb, using `protoc`. 2. Include *pb_encode.c*, *pb_decode.c* and *pb_common.c* in your project. The easiest way to get started is to study the project in "examples/simple". It contains a Makefile, which should work directly under most Linux systems. However, for any other kind of build system, see the manual steps in README.txt in that folder. Using the Protocol Buffers compiler (protoc) -------------------------------------------- The nanopb generator is implemented as a plugin for the Google's own `protoc` compiler. This has the advantage that there is no need to reimplement the basic parsing of .proto files. However, it does mean that you need the Google's protobuf library in order to run the generator. If you have downloaded a binary package for nanopb (either Windows, Linux or Mac OS X version), the `protoc` binary is included in the 'generator-bin' folder. In this case, you are ready to go. Simply run this command: generator-bin/protoc --nanopb_out=. myprotocol.proto However, if you are using a git checkout or a plain source distribution, you need to provide your own version of `protoc` and the Google's protobuf library. On Linux, the necessary packages are `protobuf-compiler` and `python-protobuf`. On Windows, you can either build Google's protobuf library from source or use one of the binary distributions of it. In either case, if you use a separate `protoc`, you need to manually give the path to nanopb generator: protoc --plugin=protoc-gen-nanopb=nanopb/generator/protoc-gen-nanopb ... Running the tests ----------------- If you want to perform further development of the nanopb core, or to verify its functionality using your compiler and platform, you'll want to run the test suite. The build rules for the test suite are implemented using Scons, so you need to have that installed (ex: `sudo apt install scons` on Ubuntu). To run the tests: cd tests scons This will show the progress of various test cases. If the output does not end in an error, the test cases were successful. Note: Mac OS X by default aliases 'clang' as 'gcc', while not actually supporting the same command line options as gcc does. To run tests on Mac OS X, use: "scons CC=clang CXX=clang". Same way can be used to run tests with different compilers on any platform. ================================================ FILE: Pods/nanopb/pb.h ================================================ /* Common parts of the nanopb library.
