An image library including image response serializers, `UIImage` and `UIImageView` extensions, custom image filters, an auto-purging in-memory cache and a priority-based image downloading system.\n- [AlamofireNetworkActivityIndicator](https://github.com/Alamofire/AlamofireNetworkActivityIndicator) - Controls the visibility of the network activity indicator on iOS using Alamofire. It contains configurable delay timers to help mitigate flicker and can support `URLSession` instances not managed by Alamofire.\n\n## Requirements\n\n- iOS 10.0+ / macOS 10.12+ / tvOS 10.0+ / watchOS 3.0+\n- Xcode 10.2+\n- Swift 5+\n\n## Migration Guides\n\n- [Alamofire 5.0 Migration Guide](https://github.com/Alamofire/Alamofire/blob/master/Documentation/Alamofire%205.0%20Migration%20Guide.md)\n- [Alamofire 4.0 Migration Guide](https://github.com/Alamofire/Alamofire/blob/master/Documentation/Alamofire%204.0%20Migration%20Guide.md)\n- [Alamofire 3.0 Migration Guide](https://github.com/Alamofire/Alamofire/blob/master/Documentation/Alamofire%203.0%20Migration%20Guide.md)\n- [Alamofire 2.0 Migration Guide](https://github.com/Alamofire/Alamofire/blob/master/Documentation/Alamofire%202.0%20Migration%20Guide.md)\n\n## Communication\n- If you **need help with making network requests** using Alamofire, use [Stack Overflow](https://stackoverflow.com/questions/tagged/alamofire) and tag `alamofire`.\n- If you need to **find or understand an API**, check [our documentation](http://alamofire.github.io/Alamofire/) or [Apple's documentation for `URLSession`](https://developer.apple.com/documentation/foundation/url_loading_system), on top of which Alamofire is built.\n- If you need **help with an Alamofire feature**, use [our forum on swift.org](https://forums.swift.org/c/related-projects/alamofire).\n- If you'd like to **discuss Alamofire best practices**, use [our forum on swift.org](https://forums.swift.org/c/related-projects/alamofire).\n- If you'd like to **discuss a feature request**, use [our forum on swift.org](https://forums.swift.org/c/related-projects/alamofire). \n- If you **found a bug**, open an issue here on GitHub and follow the guide. The more detail the better!\n- If you **want to contribute**, submit a pull request!\n\n## Installation\n\n### CocoaPods\n\n[CocoaPods](https://cocoapods.org) is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate Alamofire into your Xcode project using CocoaPods, specify it in your `Podfile`:\n\n```ruby\npod 'Alamofire', '~> 5.0'\n```\n\n### Carthage\n\n[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate Alamofire into your Xcode project using Carthage, specify it in your `Cartfile`:\n\n```ogdl\ngithub \"Alamofire/Alamofire\" \"5.0\"\n```\n\n### Swift Package Manager\n\nThe [Swift Package Manager](https://swift.org/package-manager/) is a tool for automating the distribution of Swift code and is integrated into the `swift` compiler. It is in early development, but Alamofire does support its use on supported platforms.\n\nOnce you have your Swift package set up, adding Alamofire as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.\n\n```swift\ndependencies: [\n .package(url: \"https://github.com/Alamofire/Alamofire.git\", from: \"5.0\")\n]\n```\n\n### Manually\n\nIf you prefer not to use any of the aforementioned dependency managers, you can integrate Alamofire into your project manually.\n\n#### Embedded Framework\n\n- Open up Terminal, `cd` into your top-level project directory, and run the following command \"if\" your project is not initialized as a git repository:\n\n ```bash\n $ git init\n ```\n\n- Add Alamofire as a git [submodule](https://git-scm.com/docs/git-submodule) by running the following command:\n\n ```bash\n $ git submodule add https://github.com/Alamofire/Alamofire.git\n ```\n\n- Open the new `Alamofire` folder, and drag the `Alamofire.xcodeproj` into the Project Navigator of your application's Xcode project.\n\n > It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter.\n\n- Select the `Alamofire.xcodeproj` in the Project Navigator and verify the deployment target matches that of your application target.\n- Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the \"Targets\" heading in the sidebar.\n- In the tab bar at the top of that window, open the \"General\" panel.\n- Click on the `+` button under the \"Embedded Binaries\" section.\n- You will see two different `Alamofire.xcodeproj` folders each with two different versions of the `Alamofire.framework` nested inside a `Products` folder.\n\n > It does not matter which `Products` folder you choose from, but it does matter whether you choose the top or bottom `Alamofire.framework`.\n\n- Select the top `Alamofire.framework` for iOS and the bottom one for macOS.\n\n > You can verify which one you selected by inspecting the build log for your project. The build target for `Alamofire` will be listed as either `Alamofire iOS`, `Alamofire macOS`, `Alamofire tvOS` or `Alamofire watchOS`.\n\n- And that's it!\n\n > The `Alamofire.framework` is automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.\n\n## Open Radars\n\nThe following radars have some effect on the current implementation of Alamofire.\n\n- [`rdar://21349340`](http://www.openradar.me/radar?id=5517037090635776) - Compiler throwing warning due to toll-free bridging issue in test case\n- `rdar://26870455` - Background URL Session Configurations do not work in the simulator\n- `rdar://26849668` - Some URLProtocol APIs do not properly handle `URLRequest`\n\n## Resolved Radars\n\nThe following radars have been resolved over time after being filed against the Alamofire project.\n\n- [`rdar://26761490`](http://www.openradar.me/radar?id=5010235949318144) - Swift string interpolation causing memory leak with common usage.\n - (Resolved): 9/1/17 in Xcode 9 beta 6.\n- [`rdar://36082113`](http://openradar.appspot.com/radar?id=4942308441063424) - `URLSessionTaskMetrics` failing to link on watchOS 3.0+\n - (Resolved): Just add `CFNetwork` to your linked frameworks.\n \n## FAQ\n\n### What's the origin of the name Alamofire?\n\nAlamofire is named after the [Alamo Fire flower](https://aggie-horticulture.tamu.edu/wildseed/alamofire.html), a hybrid variant of the Bluebonnet, the official state flower of Texas.\n\n## Credits\n\nAlamofire is owned and maintained by the [Alamofire Software Foundation](http://alamofire.org). You can follow them on Twitter at [@AlamofireSF](https://twitter.com/AlamofireSF) for project updates and releases.\n\n### Security Disclosure\n\nIf you believe you have identified a security vulnerability with Alamofire, you should report it as soon as possible via email to security@alamofire.org. Please do not post it to a public issue tracker.\n\n## Donations\n\nThe [ASF](https://github.com/Alamofire/Foundation#members) is looking to raise money to officially stay registered as a federal non-profit organization.\nRegistering will allow us members to gain some legal protections and also allow us to put donations to use, tax-free.\nDonating to the ASF will enable us to:\n\n- Pay our yearly legal fees to keep the non-profit in good status\n- Pay for our mail servers to help us stay on top of all questions and security issues\n- Potentially fund test servers to make it easier for us to test the edge cases\n- Potentially fund developers to work on one of our projects full-time\n\nThe community adoption of the ASF libraries has been amazing.\nWe are greatly humbled by your enthusiasm around the projects and want to continue to do everything we can to move the needle forward.\nWith your continued support, the ASF will be able to improve its reach and also provide better legal safety for the core members.\nIf you use any of our libraries for work, see if your employers would be interested in donating.\nAny amount you can donate today to help us reach our goal would be greatly appreciated.\n\n[![paypal](https://www.paypalobjects.com/en_US/i/btn/btn_donateCC_LG.gif)](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=W34WPEE74APJQ)\n\n## License\n\nAlamofire is released under the MIT license.

You can create a factory that creates it so that you can get new instance with the common handling logic from anywhere in your app.\n\n```swift\nextension ErrorHandler {\n class var defaultHandler: ErrorHandler {\n\n return ErrorHandler()\n\n // Τhe error matches and the action is called if the matches closure returns true\n .on(matches: { (error) -> Bool in\n guard let error = error as? InvalidInputsError else { return false }\n // we will ignore errors with code == 5\n return error.code != 5\n }, do: { (error) in\n showErrorAlert(\"Invalid Inputs\")\n return .continueMatching\n })\n\n // Variant using ErrorMatcher which is convenient if you want to\n // share the same matching logic elsewhere\n .on(InvalidStateMatcher(), do: { (_) in\n showErrorAlert(\"An error has occurred. Please restart the app.\")\n return .continueMatching\n })\n\n // Handle all errors of the same type the same way\n .onError(ofType: ParsingError.self, do: { (error) in\n doSomething(with: error)\n return .continueMatching\n })\n\n // Handle a specific instance of an Equatable error type\n .on(DBError.migrationNeeded, do: { (_) in\n // Db.migrate()\n return .continueMatching\n })\n\n // You can tag matchers or matches functions in order to reuse them with a more memorable alias.\n // You can use the same tag for many matchers. This way you can group them and handle their errors together.\n .tag(NSErrorMatcher(domain: NSURLErrorDomain, code: NSURLErrorNetworkConnectionLost),\n with: \"ConnectionError\"\n )\n .tag(NSErrorMatcher(domain: NSURLErrorDomain, code: NSURLErrorNotConnectedToInternet),\n with: \"ConnectionError\"\n )\n .on(tag: \"ConnectionError\") { (_) in\n showErrorAlert(\"You are not connected to the Internet. Please check your connection and retry.\")\n return .continueMatching\n }\n\n // You can use the Alamofire extensions to easily handle responses with invalid http status\n .onAFError(withStatus: 401, do: { (_) in\n showLoginScreen()\n return .continueMatching\n })\n .onAFError(withStatus: 404, do: { (_) in\n showErrorAlert(\"Resource not found!\")\n return .continueMatching\n })\n\n // Handle unknown errors.\n .onNoMatch(do: { (_) in\n showErrorAlert(\"An error occurred! Please try again. \")\n return .continueMatching\n })\n\n // Add actions - like logging - that you want to perform each time - whether the error was matched or not\n .always(do: { (error) in\n Logger.log(error)\n return .continueMatching\n })\n }\n}\n```\n### Use the default handler to handle common cases\n\nOften the cases the default handler knows about will be good enough.\n\n```swift\ndo {\n try saveStatus()\n} catch {\n ErrorHandler.defaultHandler.handle(error)\n}\n```\n\nor use the `tryWith` free function:\n\n```swift\ntryWith(ErrorHandler.defaultHandler) {\n try saveStatus()\n}\n```\n### Customize the error handler when needed.\n\nIn cases where extra context is available you can add more cases or override the ones provided already.\n\nFor example in a SendMessageViewController\n\n```swift\nsendMessage(message) { (response, error) in\n\n if let error = error {\n ErrorHandler.defaultHandler\n .on(ValidationError.invalidEmail, do: { (_) in\n updateEmailTextFieldForValidationError()\n return .continueMatching\n })\n .onAFError(withStatus: 404, do: { (_) in\n doSomethingSpecificFor404()\n return .stopMatching\n })\n .onNoMatch(do: { (_) in\n // In the context of the current screen we can provide a better message.\n showErrorAlert(\"An error occurred! The message has not been sent.\")\n // We want to override the default onNoMatch handling so we stop searching for other matches.\n return .stopMatching\n })\n .handle(error)\n }\n }\n```\n\n\n## Why?\n\nWhen designing for errors, we usually need to:\n\n1. have a **default** handler for **expected** errors\n // i.e. network, db errors etc.\n2. handle **specific** errors **in a custom manner** given **the context** of where and when they occur\n // i.e. network error while uploading a file, invalid login\n3. have a **catch-all** handler for **unknown** errors\n // i.e. errors we don't have custom handling for\n4. perform some **actions** for **all errors** both known and unknown like logging\n5. keep our code **DRY**\n\nSwift's has a very well thought error handling model keeping balance between convenience ([automatic propagation](https://github.com/apple/swift/blob/master/docs/ErrorHandlingRationale.rst#automatic-propagation)) and clarity-safety ([Typed propagation](https://github.com/apple/swift/blob/master/docs/ErrorHandlingRationale.rst#id3), [Marked propagation](https://github.com/apple/swift/blob/master/docs/ErrorHandlingRationale.rst#id4)). As a result, the compiler serves as a reminder of errors that need to be handled and at the same type it is relatively easy to propagate errors and handle them higher up the stack.\n\nHowever, even with this help from the language, achieving the goals listed above in an **ad-hoc** manner in an application of a reasonable size can lead to a lot of **boilerplate** which is **tedious** to write and reason about. Because of this friction developers quite often choose to swallow errors or handle them all in the same generic way.\n\nThis library addresses these issues by providing an abstraction over defining flexible error handling rules with an opinionated fluent API.\n" } ]
