Log All notable changes to this project will be documented in this file. ## 10.0.2 ### Features * #549 Create a formal dismissal mechanism for SwiftUI message. Use `@Environment(\.swiftMessagesHide) private var hide` then call `hide(animated: true)` to dismiss. * #571 PhysicsPanHandler.swift make configure public. ### Fixes * #581 [BUG]: SwiftUI message views don't respond to touch input on Xcode 26 beta 6 iOS 26 simulator. * #581 [BUG]: SwiftUI message views don't respond to touch input on Xcode 26 beta 6 iOS 26 simulator * #577 Hide Background Elements from Modal SwiftMessage in VoiceOver mode * #578 Fix crash on iPadOS 18+ when presenting bottom SwiftMessage above UITabBarController ### Features * #523 Add a `priority` configuration option. * #548 Adds 'TopBottomPresentable' protocol to allow animators implementation to reuse 'top/bottom' integration in presentation * #543 Make the `SwiftMessages` initializer `nonisolated` to improve interoperability with dependency injection frameworks like Factory. * #560 Add a new `swiftMessage` modifier variation that provides a ` MessageGeometryProxy` type to the message view builder—this works around an inssue with `GeometryReader` not working in `UIHostingController`. ### Fixes * Fix broken touch handling in iOS 18. ## 10.0.0 ### Features * Add a variation on the `.swiftMessage()` modifier that takes a view builder instead of requiring that the bound value conform to `MessageViewConvertible`. This syntax is more similar to the familiar `sheet()` modifier syntax and provides more flexibility for constructing message views. * #207 Add optional haptic feedback ### Changes * Use `@MainActor` to ensure that SwiftMessages is not called from a background queue. * Bump minimum deployment target to iOS 13. ### Fixes * #535 window being accessed from background thread when dequeueNext is called * #534 Xcode warnings in two swift files * #533 How do I show a message that appears above the keyboard, when the keyboard is already visible? ## 9.0.9 ### Fixes * Fix hit testing on SwiftUI views to allow touches around the view's margins to pass through to the underlying view. * Update `KeyboardTrackingView` to continue tracking the keyboard even when not installed in the view hierarchy. ## 9.0.8 ### Changes * #529 Update readme and SwiftUI demo to demostrate how to mask edges. ## 9.0.7 ### Features * Added support for SwiftUI ### Fixes * #527 Crash while clicking two times to hide the presenting controller * #517 Prevent orphaned views from blocking the queue * Prevent orphaned `SwiftMessagesSeque`s from retaining the presenting view controller ## 9.0.6 ### Features * Add `UIView` associated type to `Event`, e.g. `willShow(UIView)` so that event listeners can inspect the view. * Add `Event.id: String?` property so that event listeners can reason about the view's ID. ## 9.0.5 ### Fixes * #482 Fix timing of `KeyboardTrackingView` callbacks. * #483 KeyboardTrackingView causes a small space under bottom-style view ## 9.0.4 * #471 Xcode 13 issue - Enum cases with associated values cannot be marked potentially unavailable with '@available' * Improve colors for dark mode. ## 9.0.3 ### Fixes * #467 Lower or equal level window's views disappear upon hide * #466 Alert not shown after Biometry check * #465 Fix broken Carthage build. The Carthage build was broken due to the `iMessageDemo` project's use of CocoaPods and the automatically generated `SwiftMessages` framework scheme created by CocoaPods. The podfile was modified to delete this scheme, but Carthage users may need to run `pod install` on the `iMessagesDemo` project, if they have CocoaPods installed, or manually delete the `iMessageDemo/Pods/Pods.xcodeproj/xcuserdata` folder. ## 9.0.2 ### Fixes * Fix app extension compile error when using CocoaPods. ## 9.0.1 ### Fixes * #455 #458 Restore key window after message is interacted with. When a message becomes the key window, such as if the user interacts with the message, iOS does not automatically restore the previous key window when the message is dismissed. SwiftMessages has some logic in `WindowViewController` to restore the key window. This change makes that logic more robust. ## 9.0.0 ### Features * #447 Add the ability to show view controller in a new window with `SwiftMessagesSegue`. This capability is available when using `SwiftMessagesSegue` programmatically by supplying an instance of `WindowViewController` as the segue's source view controller. ### Changes * This release has minor breaking changes in the `WindowViewController` initializers. The `windowLevel` is no longer accepted as an argument because the `config` parameter should specify the window level in the `presentationContext` property. ### Fixes * #451 Fix app extension crash ## 8.0.5 ### Fixes * #446 Restore previous key window on dismissal if the message assumed key window status. ## 8.0.4 ### Features * #442 Add `MarginAdjustable.respectSafeArea` option to exclude safe area from layout margins. * #430 Support disable `becomeKeyWindow` from SwiftMessages.Config. This is a workaround for potential issues with apps that display additional windows. ### Fixes * #437 Revert to explicitly specifying "SwiftMessages" as the module in nib files. * #440 Fix crash when using SwiftMessages in app extension ## 8.0.3 ### Features * Full support for Swift Package Manager ### Fixes * #328 ignoreDuplicates is not working * #412 Fix deployment target on nib files to match target ## 8.0.2 ### Changes * [#395](https://github.com/SwiftKickMobile/SwiftMessages/pull/395) Add preliminary support for Swift Package Manager. ## 8.0.1 ### Fixes * #401 UIAlertController pops up but SwiftMessage layer absorbs all touches. ## 8.0.0 ### Changes * Add `SwiftMessages.PresentationContext.windowScene` option for targeting a specific window scene. * Changed the behavior of the default `presentationContext`, `.automatic`. Previously, if the root view controller was presenting, the message would only be displayed over the presented view controller if the `modalPresentationStyle` was `fullScreen` or `overFullScreen`. Now, messages are always displayed over presented view controllers. * Made `showDuraton` and `hideDuration` on `Animator` non-optional. * Made `showDuraton` and `hideDuration` writable options on `TopBottomAnimation` and `PhysicsAnimation`. ### Fixes * #365 Fix an issue with customized `TopBottomAnimation` where messages weren't properly displayed under navigation and tab bars. * #352 Fix accessibility for view controllers presented with `SwiftMessagesSegue`. * #355 Update card view layout to support centering of pure textual content * #354 Support `overrideUserInterfaceStyle` when view presented in its own window * #360 Fix touch handing issue in iOS 13.1.3 * #382 Fix warnings in Xcode 11.4 ## 7.0.1 ### Changes * Support iOS 13. ### Features * #335 Add option to hide status bar when view is displayed in a window. As of iOS 13, windows can no longer cover the status bar. The only alternative is to set `Config.prefersStatusBarHidden = true` to hide it. ## 7.0.0 ### Changes * Swift 5 * Remove deprecated APIs ### Features * #313 Improved sizing on iPad >`SwiftMessagesSegue` provides default view controller sizing based on device, with width on iPad being limited to 500pt max. However, it is recommended that you explicitly specify size appropriate for your content using one of the following methods. > 1. Define sufficient width and height constraints in your view controller such that it sizes itself. > 1. Set the `preferredContentSize` property (a.k.a "Use Preferred Explicit Size" in Interface Builder's attribute inspector). Zeros are ignored, e.g. `CGSize(width: 0, height: 350)` only affects the height. > 1. Add explicit width and/or height constraints to `segue.messageView.backgroundView`. > >Note that `Layout.topMessage` and `Layout.bottomMessage` are always full screen width. For other layouts, the there is a maximum 500pt width on for regular horizontal size class (iPad) at 950 priority. This limit can be overridden by adding higher-priority constraints. * #275 Add ability to avoid the keyboard. >The `KeyboardTrackingView` class can be used to cause the message view to avoid the keyboard by sliding up when the keyboard gets too close. > >````swift >// Message view >var config = SwiftMessages.defaultConfig >config.keyboardTrackingView = KeyboardTrackingView() > >// Or view controller >segue.keyboardTrackingView = KeyboardTrackingView() >```` >You can incorporate `KeyboardTrackingView` into your app even when you're not using SwiftMessages. Install into your view hierarchy by pinning `KeyboardTrackingView` to the bottom, leading, and trailing edges of the screen. Then pin the bottom of your content that should avoid the keyboard to the top `KeyboardTrackingView`. Use an equality constraint to strictly track the keyboard or an inequality constraint to only move when the keyboard gets too close. `KeyboardTrackingView` works by observing keyboard notifications and adjusting its height to maintain its top edge above the keyboard, thereby pushing your content up. See the comments in `KeyboardTrackingView` for configuration options. * #276 Add ability to hide message without animation * #272 Add duration for `SwiftMessagesSegue` * #278 Make pan gesture recognizers public ## 6.0.2 ### Features * #262 Add event listeners to `SwiftMessagesSegue`. ## 6.0.1 ### Features * #257 The `.centered` presentation style, which is a shortcut for a specific configuration of the `PhysicsAnimation` animator, provides a physics-based dismissal gesture where the view can be flung off screen. When the view goes out of the container view's bounds, the animator calls `SwiftMessages.hide()`, which animates the dim view away and concludes the message view's lifecycle. There is currently a small delay of 0.2s before calling `hide()`. This change adds the ability to configure the delay by customizing the animator. For example, to set the delay to zero, one would do: ````swift let animation = PhysicsAnimation() animation.panHandler.hideDelay = 0 config.presentationStyle = .custom(animator: animation) ```` ## 6.0.0 ### Changes * Migrate to Swift 4.2 ### Fixes * Fix #228 restore shared SwiftMessages scheme ## 5.0.1 ### Fixes * Remove debug code that broke the view controller's section of the Demo app. ## 5.0.0 ### Breaking Changes * Removed support for iOS 8. ### Features * Add support for modal view controller presentation using [`SwiftMessagesSegue`](./SwiftMessages/SwiftMessagesSegue.swift) custom segue subclass. Try it out in the "View Controllers" section of the Demo app. In addition to the class documentation, more can be found in the [View Controllers](./ViewControllers.md) readme. * Update nib files to be more visually consistent with iPhone X: * Introduce [`CornerRoundingView`](./SwiftMessages/CornerRoundingView.swift), which provides configurable corner rounding using squircles (the smoother method of rounding corners that you see on app icons). Nib files that feature rounded corners have their `backgroundView` assigned to a `CornerRoundingView`. `CornerRoundingView` provides a `roundsLeadingCorners` option to dynamically round only the leading corners of the view when presented from top or bottom (a feature used for the tab-style layouts). * Increased the default corner radius to 20. Corner radius can be changed by either modifying the nib file or * Reworked the [`MarginAdjustable`](./SwiftMessages/MarginAdjustable.swift) to improve configurability of layout margins. * Add rubber-banding to the interactive dismissal gesture. Rubber banding is automatically applied for views where `backgroundView` is inset from the message view's edges. * Added `showDuration` and `hideDuration` properties to the `Animator` protocol (with default implementation that returns `nil`). These values enable animations to work for view controller presentation. ### Fixes * #202 bodyLabel should set textAlignment to .natural * #200 Automatic Presentation Context Broken * Fix default value of `TopBottomAnimation.closePercentThreshold` ## 4.1.4 ### Bug Fixes * Fix #191 Prevent usage of UIApplication.shared when building for extensions ### Improvements * #192 Add a way to test compilation with app extension ## 4.1.3 ### Features * #183 Added iOS app extension support at compile time. ### Bug Fixes * Fix #185 Incorrect margin adjustments in landscape * Fix #188 Physics animation visual glitch ## 4.1.2 ### Features * Updates for Swift 4.1 * #164 Added an optional `windowViewController` property to `SwiftMessages.Config` for supplying a custom subclass of `WindowViewController`. ### Bug Fixes * Custom presentation styles using `TopBottomAnimation` now display properly under top and bottom bars. ## 4.1.1 ### Features * #152 Get current message being displayed without specifying an `id` ## 4.1.0 ### Features * Fix #134 add support for `CenterAnimation` displayed on top or bottom instead of center (renamed to `PhysicsAnimation`). ### Fixes * Fix #128 move icons out of asset catalog to prevent mysterious crash * Fix #129 adjust layout margins on orientation change to preserve layout when iOS hides status bar in landscape. * Fix #131 by always completing hide/show animations if application isn't active. ## 4.0.0 ### Features * Swift 4.0 syntax * Added support for iOS 11 and iPhone X. From the readme: SwiftMessages 4 supports iOS 11 out-of-the-box with built-in support for safe areas. To ensur that message view layouts look just right when overlapping safe areas, views that adopt the `MarginAdjustable` protocol (like `MessageView`) will have their layout margins automatically adjusted by SwiftMessages. However, there is no one-size-fits-all adjustment, so the following properties were added to `MarginAdjustable` to allow for additional adjustments to be made to the layout margins: ````swift public protocol MarginAdjustable { ... /// Safe area top adjustment in iOS 11+ var safeAreaTopOffset: CGFloat { get set } /// Safe area bottom adjustment in iOS 11+ var safeAreaBottomOffset: CGFloat { get set } } ```` If you're using using custom nib files or view classes and your layouts don't look quite right, try adjusting the values of these properties. `BaseView` (the super class of `MessageView`) declares these properties to be `@IBDesignable` and you can find sample values in the nib files included with SwiftMessages. ### Bug Fixes * Fix #100 memory leak. * Change `Layout` enum capitalization to current Swift conventions. ## [3.5.1](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.5.0) ### Bug Fixes * Undo change that broke `MessageView` class reference on nib files copied out of the SwiftMessages framework. ## [3.5.0](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.5.0) ### Features * Added `SwiftMessages.hideCounted(id:)` method of hiding. The counted method hides when the number of calls to `show()` and `hideCounted(id:)` for a given message ID are equal. This can be useful for messages that may be shown from multiple code paths to ensure that all paths are ready to hide. Also added `SwiftMessages.count(id:)` to get the current count and `SwiftMessages.set(id:count:)` to set the current count. * Added ways to retrieve message views currently being shown, hidden, or queued to be shown. ````swift // Get a message view with the given ID if it is currently // being shown or hidden. if let view = SwiftMessages.current(id: "some id") { ... } // Get a message view with the given ID if is it currently // queued to be shown. if let view = SwiftMessages.queued(id: "some id") { ... } // Get a message view with the given ID if it is currently being // shown, hidden or in the queue to be shown. if let view = SwiftMessages.currentOrQueued(id: "some id") { ... } ```` ### Bug Fixes * Fix #116 for message views that don't adopt the `Identifiable` protocol by using the memory address as the ID. * Fix #113 MessageView not hiding * Fix #87 Support manual install ## [3.4.0](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.4.0) ### Features * Added `.center` presentation style with a physics-based dismissal gesture. * Added `.custom(animator:)` presentation style, where you provide an instance of the `Animator` protocol. The `TopBottomAnimation` and `CenterAnimation` animations both implement `Animator` and may be subclassed (configuration options will be added in a future release). `PhysicsPanHandler` class to provide a physics-based dismissal gesture. * Added `.centered` message view layout with elements centered and arranged vertically. * Added `configureBackgroundView(width:)` and `configureBackgroundView(sideMargin:)` convenience methods to `MessageView`. ## [3.3.4](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.3.4) ### Features * #89 Add `blur` dim mode option. ### Bug Fixes * #98 Fix touch handling in message view's background view. * #97 Fix main thread checker warning ## [3.3.3](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.3.3) ### Bug Fixes * Fix an issue where rapidly showing and hiding messages could result in messages becoming orphaned on-screen. ## [3.3.2](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.3.2) ### Improvements * `MessageView` is smarter about including additional accessibility views for cases where you've added accessible elements to the view. Previously only the `button` was included. Now all views where `isAccessibilityElement == true`. Note that all nib files now have `isAccessibilityElement == false` for `titleLabel`, `bodyLabel` and `iconLabel` (`titleLabel` and `bodyLabel` are read out as part of the overall message view's text). If any of these need to be directly accessible, then copy the nib file into your project and select "Enabled" in the Accessibility section of the Identity Inspector. ## [3.3.1](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.3.1) ### Bug Fixes * Fix regression where the UI was being blocked when using `DimMode.none`. ## [3.3.0](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.3.0) ### Features * Add proper support for VoiceOver. See the [Accessibility section](README.md#accessibility) of the readme. ## [3.2.1](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.2.1) ### Bug Fixes * Fix infinite loop bug introduced in 3.2.0. ## [3.2.0](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.2.0) ### Features * Added the ability to display messages for an indefinite duration while enforcing a minimum duration using `Duration.indefinite(delay:minimum)`. This option is useful for displaying a message when a process is taking too long but you don't want to display the message if the process completes in a reasonable amount of time. For example, if a URL load is expected to complete in 2 seconds, you may use the value `unknown(delay: 2, minimum 1)` to ensure that the message will not be displayed most of the time, but will be displayed for at least 1 second if the operation takes longer than 2 seconds. By specifying a minimum duration, you can avoid hiding the message too fast if the operation finishes right after the delay interval. ### Bug Fixes * Prevent views below the dim view from receiving accessibility focus. * Prevent taps in the message view from hiding when using interactive dim mode. * Fix memory leak of single message view ## [3.1.5](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.1.5) ### Bug Fixes * Fix memory leak of `MessageViews`. ## [3.1.4](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.1.4) ### Bug Fixes * Fixed an issue where UIKit components were being instantiated off the main queue. ## [3.1.3](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.1.3) ### Features * Added the ability to set a custom value on `MessageView.id`. This can be useful for dismissing specific messages using a pre-defined `id`. ## [3.1.2](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.1.2) ### Features * Changed the default behavior when a message is displayed in its own window (such as with `.window` presentation context) to no longer become the key window in order to prevent the keyboard from dismissing. If one needs the message's window to become key, this can be done by setting `SwiftMessages.Config.becomeKeyWindow` to `true`. See ### Bug Fixes * Changed the internal logic of hiding a message view to always succeed to work around the problem of the hide animation failing, such as when started while the app is not active. * Improved reliability of the automatic adjustments made to avoid message views overlapping the status bar, particularly when using the `.view` presentation context. ## [3.1.1](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.1.1) ### Features * Added a `view` case to `presentationContext` for displaying the message in a specific container view. ## [3.1.0](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.1.0) ### Features * Add `eventListeners` option to `SwiftMessages.Config` to specify a list of event listeners to be notified of message show and hide events. ## [3.0.3](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.0.3) ### Features * Add `ignoreDuplicates` option to `SwiftMessages.Config` to specify whether or not to ignore duplicate `Identifiable` message views. ## [3.0.2](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.0.2) ### Features * Add `shouldAutorotate` option to `SwiftMessages.Config` for customizing device rotation behavior when messages are presented in an overlay window. By default, message will auto-rotate. ## [3.0.1](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.0.1) ### Improvements * Enable automatic provisioning on framework target ## [3.0.0](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/3.0.0) ### Breaking Changes * Support for Swift 3.0. ## [2.0.0](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/2.0.0) ### Breaking Changes * Support for Swift 2.3 and Xcode 8. The nib files needed to be updated to Xcode 8 format to work around an iOS bug. Unfortunately, this makes it necessary to break backward compatibility with Swift 2.2 and Xcode 7. ## [1.1.4](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/1.1.4) ### Bug Fixes * Fix #16 Preserve status bar visibility when displaying message in a new window. ## [1.1.3](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/1.1.3) ### Features * Add default configuration `SwiftMessages.defaultConfig` that can be used when calling the variants of `show()` that don't take a `config` argument or as a global base for custom configs. * Add `Array.sm_random()` function that returns a random element from the array. Can be used to create a playful message that cycles randomly through a set of emoji icons, for example. ### Bug Fixes * Fix #5 Emoji not shown! * Fix #6 There is no way to create SwiftMessages instance as there is no public initializer ## [1.1.2](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/1.1.2) ### Bug Fixes * Fix Carthage-related issues. ## [1.1.1](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/1.1.1) ### Features * New layout `Layout.TabView` — like `Layout.CardView` with one end attached to the super view. ### Bug Fixes * Fix spacing between title and body text in `Layout.CardView` when body text wraps. ## [1.1.0](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/1.1.0) ### Improvements ### API Changes * The `BaseView.contentView` property of was removed because it no longer had any functionality in the framework. This is a minor backwards incompatible change. If you've copied one of the included nib files from a previous release, you may get a key-value coding runtime error related to contentView, in which case you can subclass the view and add a `contentView` property or you can remove the outlet connection in Interface Builder. ## [1.0.3](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/1.0.2) ### Improvements * Remove the `iconContainer` property from `MessageView`. ### Bug Fixes * Fix constraints generated by `BaseView.installContentView()`. ## [1.0.2](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/1.0.2) ### Features * Add support for specifying an `IconStyle` in the `MessageView.configureTheme()` convenience function. ## [1.0.1](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/1.0.1) * Add code comments. ## [1.0.0](https://github.com/SwiftKickMobile/SwiftMessages/releases/tag/1.0.0) * Initial release. ================================================ FILE: Demo/.Podfile ================================================ target 'Demo' do use_frameworks! workspace 'Demo.xcworkspace' xcodeproj 'Demo.xcodeproj' pod 'SwiftMessages/App', :path => '../' pod 'SwiftMessages/SegueExtras', :path => '../' end ================================================ FILE: Demo/Demo/AppDelegate.swift ================================================ // // AppDelegate.swift // Demo // // Created by Tim Moose on 8/11/16. // Copyright © 2016 SwiftKick Mobile.

## Overview 🔥🔥🔥 **UPDATE** SwiftUI support in in Xcode 26 requries 10.0.2! SwiftMessages is a very flexible view and view controller presentation library for UIKit and SwiftUI. Message views and view controllers can be displayed at the top, bottom, or center of the screen, or behind navigation bars and tab bars. There are interactive dismiss gestures including a fun, physics-based one. Multiple background dimming modes. And a lot more! In addition to the numerous configuration options, SwiftMessages provides several good-looking layouts and themes. But SwiftMessages is also designer-friendly, which means you can fully and easily customize the view: * Copy one of the included nib files into your project and change it. * Subclass `MessageView` and add elements, etc. * Or just supply an arbitrary instance of `View` or `UIView`.

## Installation ### Swift Package Manager Go to `File | Swift Packages | Add Package Dependency...` in Xcode and search for "SwiftMessages". If multiple results are found, select the one owned by SwiftKick Mobile. ### CocoaPods Add the following line to your Podfile: ````ruby pod 'SwiftMessages' ```` ### Carthage Add the following line to your Cartfile: ````ruby github "SwiftKickMobile/SwiftMessages" ```` If the Carthage build fails, [try using the script](https://github.com/Carthage/Carthage/issues/3019). ### Manual 1. Put SwiftMessages repo somewhere in your project directory. 1. In Xcode, add `SwiftMessages.xcodeproj` to your project. 1. On your app's target, add the SwiftMessages framework: 1. as an embedded binary on the General tab. 1. as a target dependency on the Build Phases tab. ## Usage ### Basics ````swift SwiftMessages.show(view: myView) ```` Although you can show any instance of `UIView`, SwiftMessages provides a `MessageView` class and assortment of nib-based layouts that should handle most cases: ````swift // Instantiate a message view from the provided card view layout. SwiftMessages searches for nib // files in the main bundle first, so you can easily copy them into your project and make changes. let view = MessageView.viewFromNib(layout: .cardView) // Theme message elements with the warning style. view.configureTheme(.warning) // Add a drop shadow. view.configureDropShadow() // Set message title, body, and icon.

SwiftMessages.show(view: view) ```` You may wish to use the view provider variant `show(viewProvider:)` to ensure that your UIKit code is executed on the main queue: ````swift SwiftMessages.show { let view = MessageView.viewFromNib(layout: .cardView) // ... configure the view return view } ```` The `SwiftMessages.Config` struct provides numerous configuration options that can be passed to `show()`: ````swift var config = SwiftMessages.Config() // Slide up from the bottom. config.presentationStyle = .bottom // Display in a window at the specified window level. config.presentationContext = .window(windowLevel: .statusBar) Note that, as of iOS 13, it is no longer possible to cover the status bar regardless of the window level. A workaround is to hide the status bar instead. config.prefersStatusBarHidden = true // Disable the default auto-hiding behavior. config.duration = .forever // Dim the background like a popover view. Hide when the background is tapped. config.dimMode = .gray(interactive: true) // Disable the interactive pan-to-hide gesture. config.interactiveHide = false // Specify haptic feedback (see also MessageView/configureTheme) config.haptic = .success // Specify a status bar style to if the message is displayed directly under the status bar. config.preferredStatusBarStyle = .lightContent // Specify one or more event listeners to respond to show and hide events. config.eventListeners.append() { event in if case .didHide = event { print("yep id=\(String(describing: event.id)") } } SwiftMessages.show(config: config, view: view) ```` Specify default configuration options: ````swift SwiftMessages.defaultConfig.presentationStyle = .bottom // Show message with default config. SwiftMessages.show(view: view) // Customize config using the default as a base. var config = SwiftMessages.defaultConfig config.duration = .forever SwiftMessages.show(config: config, view: view) ```` ### View Controllers SwiftMessages can present view controllers using the `SwiftMessagesSegue` custom modal segue!

[`SwiftMessagesSegue`](./SwiftMessages/SwiftMessagesSegue.swift) is a subclass of `UIStoryboardSegue` that integrates directly into Interface Builder as a custom modal segue, enabling view controllers to take advantage of SwiftMessages layouts, animations and more. `SwiftMessagesSegue` works with any UIKIt project — storyboards are not required. Refer to the View Controllers readme below for more information. #### [View Controllers Readme](./ViewControllers.md) And check out our blog post [Elegant Custom UIViewController Transitioning](http://www.swiftkickmobile.com/elegant-custom-uiviewcontroller-transitioning-uiviewcontrollertransitioningdelegate-uiviewcontrolleranimatedtransitioning/) to learn a great technique you can use to build your own custom segues that utilize `UIViewControllerTransitioningDelegate` and `UIViewControllerAnimatedTransitioning`. ### SwiftUI Any of the built-in SwiftMessages views can be displayed by calling the SwiftMessages APIs from within observable object, a button action closure, etc. However, SwiftMessages can also display your custom SwiftUI views. #### Presentation Take the following message view and companion data model: ````swift struct DemoMessage: Identifiable { let title: String let body: String var id: String { title + body } } struct DemoMessageView: View { let message: DemoMessage var body: some View { VStack(alignment: .leading) { Text(message.title).font(.system(size: 20, weight: .bold)) Text(message.body) } .multilineTextAlignment(.leading) .padding(30) // This makes the message width greedy .frame(maxWidth: .infinity) .background(.gray) // This makes a tab-style view where the bottom corners are rounded and // the view's background extends to the top edge. .mask( UnevenRoundedRectangle(bottomLeadingRadius: 15, bottomTrailingRadius: 15) // This causes the background to extend into the safe area to the screen edge. .edgesIgnoringSafeArea(.top) ) } } ```` You can show it from a button action, view model or other similar context like: ````swift struct DemoView: View { var body: some View { Button("Show message") { let message = DemoMessage(title: "Demo", body: "SwiftUI forever!") let messageView = MessageHostingView(id: message.id, content: DemoMessageView(message: message) SwiftMessages.show(view: messageView) } } } ```` But you may also use a state-based approach using the `swiftMessage()` view modifier: ````swift struct DemoView: View { @State var message: DemoMessage? var body: some View { Button("Show message") { message = DemoMessage(title: "Demo", body: "SwiftUI forever!") } .swiftMessage(message: $message) { message in DemoMessageView(message: message) } } } ```` This is very similar to the `.sheet()` modifier. However, it doesn't expose all of the features of SwiftMessages, such as explicitly hiding messages by ID. It is totally reasonable to use a combination of both approaches. If your message views are purely data-driven and don't require delegates, callbacks, etc., there is a slightly simplified variation on `swiftMessage()` that doesn't require a view builder. Instead, your data model should conform to `MessageViewConvertible`. ````swift extension DemoMessage: MessageViewConvertible { func asMessageView() -> DemoMessageView { DemoMessageView(message: self) } } ```` Then you can drop the view builder when calling `swiftMessage()`: ````swift struct DemoView: View { @State var message: DemoMessage? var body: some View { Button("Show message") { message = DemoMessage(title: "Demo", body: "SwiftUI forever!") } .swiftMessage(message: $message) } } ```` #### Dismissal SwiftMessages provides several approaches for dismissing messages from within SwiftUI views. For messages shown using the `swiftMessage()` modifier, you can dismiss by setting the binding to `nil`: ````swift struct DemoView: View { @State var message: DemoMessage? var body: some View { VStack { Button("Show message") { message = DemoMessage(title: "Demo", body: "SwiftUI forever!") } Button("Hide message") { message = nil // Dismisses the message } } .swiftMessage(message: $message) { message in DemoMessageView(message: message) } } } ```` For messages that need to dismiss themselves, SwiftMessages provides a SwiftUI-style environment action: ````swift struct SelfDismissingMessageView: View { @Environment(\.swiftMessagesHide) private var hide let message: DemoMessage var body: some View { VStack(alignment: .leading) { Text(message.title).font(.system(size: 20, weight: .bold)) Text(message.body) Button("Dismiss") { hide(animated: true) // Self-dismiss with animation } } .padding(30) .frame(maxWidth: .infinity) .background(.gray) } } ```` You can also call the SwiftMessages APIs directly from within your SwiftUI views: ````swift Button("Hide Current") { SwiftMessages.hide() } ```` Try it out in the SwiftUI demo app! ### Accessibility SwiftMessages provides excellent VoiceOver support out-of-the-box. * The title and body of the message are combined into a single announcement when the message is shown. The `MessageView.accessibilityPrefix` property can be set to prepend additional clarifying text to the announcement. Sometimes, a message may contain important visual cues that aren't captured in the title or body. For example, a message may rely on a yellow background to convey a warning rather than having the word "warning" in the title or body. In this case, it might be helpful to set `MessageView.accessibilityPrefix = "warning"`. * If the message is shown with a dim view using `config.dimMode`, elements below the dim view are not focusable until the message is hidden. If `config.dimMode.interactive == true`, the dim view itself will be focusable and read out "dismiss" followed by "button". The former text can be customized by setting the `config.dimModeAccessibilityLabel` property. See the `AccessibleMessage` protocol for implementing proper accessibility support in custom views. ### Keyboard Avoidance The `KeyboardTrackingView` class can be used to cause the message view to avoid the keyboard by sliding up when the keyboard gets too close. ````swift var config = SwiftMessages.defaultConfig config.keyboardTrackingView = KeyboardTrackingView() ```` You can incorporate `KeyboardTrackingView` into your app even when you're not using SwiftMessages. Install into your view hierarchy by pinning `KeyboardTrackingView` to the bottom, leading, and trailing edges of the screen. Then pin the bottom of your content that should avoid the keyboard to the top `KeyboardTrackingView`. Use an equality constraint to strictly track the keyboard or an inequality constraint to only move when the keyboard gets too close. `KeyboardTrackingView` works by observing keyboard notifications and adjusting its height to maintain its top edge above the keyboard, thereby pushing your content up. See the comments in `KeyboardTrackingView` for configuration options. ### Message Queueing You can call `SwiftMessages.show()` as many times as you like. SwiftMessages maintains a queue and shows messages one at a time. If your view implements the `Identifiable` protocol (like `MessageView`), duplicate messages will be removed automatically. The pause between messages can be adjusted: ````swift SwiftMessages.pauseBetweenMessages = 1.0 ```` There are a few ways to hide messages programatically: ````swift // Hide the current message. SwiftMessages.hide() // Or hide the current message and clear the queue. SwiftMessages.hideAll() // Or for a view that implements `Identifiable`: SwiftMessages.hide(id: someId) // Or hide when the number of calls to show() and hideCounted(id:) for a // given message ID are equal. This can be useful for messages that may be // shown from multiple code paths to ensure that all paths are ready to hide. SwiftMessages.hideCounted(id: someId) ```` Multiple instances of `SwiftMessages` can be used to show more than one message at a time. Note that the static `SwiftMessages.show()` and other static APIs on `SwiftMessage` are just convenience wrappers around the shared instance `SwiftMessages.sharedInstance`). Instances must be retained, thus it should be a property of something (e.g. your view controller): ````swift class SomeViewController: UIViewController { let otherMessages = SwiftMessages() func someMethod() { SwiftMessages.show(...) otherMessages.show(...) } } ```` ### Retrieving Messages There are several APIs available for retrieving messages that are currently being shown, hidden, or queued to be shown. These APIs are useful for updating messages when some event happens without needing to keep temporary references around. See also `eventListeners`. ````swift // Get a message view with the given ID if it is currently // being shown or hidden. if let view = SwiftMessages.current(id: "some id") { ... } // Get a message view with the given ID if is it currently // queued to be shown. if let view = SwiftMessages.queued(id: "some id") { ... } // Get a message view with the given ID if it is currently being // shown, hidden or in the queue to be shown. if let view = SwiftMessages.currentOrQueued(id: "some id") { ... } ```` ### Customization SwiftMessages can display any `UIView`. However, there are varying degrees of customization that can be done to the bundled views. #### Nib Files All of the message designs bundled with SwiftMessages have associated nib files. You are encouraged to copy any of these nib files into your project and modify them to suit your needs. SwiftMessages will load your copy of the file instead of the original. Nib files may be copied in Xcode using drag-and-drop. To facilitate the use of nib-based layouts, `MessageView` provides some type-safe convenience methods for loading the bundled nibs: ````swift let view = MessageView.viewFromNib(layout: .cardView) ```` In addition, the `SwiftMessages` class provides some generic loading methods: ````swift // Instantiate MessageView from a named nib. let view: MessageView = try! SwiftMessages.viewFromNib(named: "MyCustomNib") // Instantiate MyCustomView from a nib named MyCustomView.nib. let view: MyCustomView = try! SwiftMessages.viewFromNib() ```` #### MessageView Class [`MessageView`](./SwiftMessages/MessageView.swift) is a light-weight view that all of the bundled designs use. It primarily consists of the following optional `@IBOutlet` properties: Element | Declaration | Description --------|-----------|----- Title | `titleLabel: UILabel?` | The message title. Message body | `bodyLabel: UILabel?` | The body of the message. Image icon | `iconImageView: UIImageView?` | An image-based icon. Text icon | `iconLabel: UILabel?` | A text-based (emoji) alternative to the image icon. Button | `button: UIButton?` | An action button. The SwiftMessages nib file use `MessageView` as the top-level view with content connected to these outlets. The layouts are done using stack views, which means that you can remove an element by simply hiding it: ````swift view.titleLabel.isHidden = true ```` A common mistake is attempting to remove an element by setting the corresponding outlet to `nil`. This does not work because it does not remove the element from the view hierarchy. #### Configuration `MessageView` provides numerous methods that follow the `configure*` naming convention: ````swift view.configureTheme(.warning, includeHaptic: true) view.configureContent(title: "Warning", body: "Consider yourself warned.", iconText: "🤔") ```` All of these methods are shortcuts for quickly configuring the underlying view properties. SwiftMessages strives to avoid doing any internal magic in these methods, so you do not need to call them. You can configure the view properties directly or combine the two approaches. #### Interaction `MessageView` provides an optional block-based tap handler for the button and another for the view itself: ````swift // Hide when button tapped messageView.buttonTapHandler = { _ in SwiftMessages.hide() } // Hide when message view tapped messageView.tapHandler = { _ in SwiftMessages.hide() } ```` #### Extending The suggested method for starting with `MessageView` as a base and __adding new elements__, such as additional buttons, is as follows: 1. Copy one of the bundled nib files into your project or create a new one from scratch. 1. Add new elements to the nib file. 1. Sublcass `MessageView` and create outlets for the new elements. 1. Assign the top-level view in the nib file to the subclass. 1. Connect outlets between the nib file and the subclass. 1. (recommended) override the implementation of `Identifiable` as needed to incorporate new elements into the message's identity. 1. (recommended) override the implementation of `AccessibleMessage` as needed to incorporate new elements into Voice Over. 1. Use one of the nib-loading methods above to load the view. #### BaseView Class [`BaseView`](./SwiftMessages/BaseView.swift) is the superclass of `MessageView` and provides numerous options that aren't specific to the "title + body + icon + button" design of `MessageView`. Custom views that are significantly different from `MessageView`, such as a progress indicator, should subclass `BaseView`. #### CornerRoundingView Class [`CornerRoundingView`](./SwiftMessages/CornerRoundingView.swift) is a custom view that messages can use for rounding all or a subset of corners with squircles (the smoother method of rounding corners that you see on app icons). The nib files that feature rounded corners have `backgroundView` assigned to a `CornerRoundingView`. It provides a `roundsLeadingCorners` option to dynamically round only the leading corners of the view when presented from top or bottom (a feature used for the tab-style layouts). #### Animator Protocol [`Animator`](./SwiftMessages/Animator.swift) is the protocol that SwiftMessages uses for presentation and dismissal animations. Custom animations can be done through the `SwiftMessages.PresentationStyle.custom(animator:)`. Some related components: * [`TopBottomAnimation`](./SwiftMessages/TopBottomAnimation.swift) is a sliding implementation of `Animator` used internally by `.top` and `.bottom` presentation styles. It provides some customization options. * [`PhysicsAnimation`](./SwiftMessages/PhysicsAnimation.swift) is a scaling + opacity implementation of `Animator` used internally by the `.center` presentation style. It provides a fun physics-based dismissal gesture and provides customization options including `.top` and `.bottom` placement. * [`PhysicsPanHandler`](./SwiftMessages/PhysicsPanHandler.swift) provides the physics-based dismissal gesture for `PhysicsAnimation` and can be incorporated into other `Animator` implementations. High-quality PRs for cool `Animator` implementations are welcome! #### MarginAdjustable Protocol [`MarginAdjustable`](./SwiftMessages/MarginAdjustable.swift) is a protocol adopted by `BaseView`. If the view being presented adopts `MarginAdjustable`, SwiftMessages takes ownership of the view's layout margins to ensure ideal spacing across the full range of presentation contexts. #### BackgroundViewable Protocol [`BackgroundViewable`](./SwiftMessages/BackgroundViewable.swift) is a protocol adopted by `BaseView` and requires that a view provide a single `backgroundView` property. `BaseView` initializes `backgroundView = self`, which you can freely re-assign to any subview. If the view being presented adopts `BackgroundViewable`, SwiftMessages will ignore touches outside of `backgroundView`. This is important because message views always span the full width of the device. Card and tab-style layouts appear inset from the edges of the device because the message view's background is transparent and `backgroundView` is assigned to a subview constrained to the layout margins. In these layouts, touches in the transparent margins should be ignored. #### Identifiable Protocol [`Identifiable`](./SwiftMessages/Identifiable.swift) is a protocol adopted by `MessageView` and requires that a view provide a single `id` property, which SwiftMessages uses for message deduplication. `MessageView` computes the `id` based on the message content, but `id` can also be set explicitly as needed. #### AccessibleMessage Protocol [`AccessibleMessage`](./SwiftMessages/AccessibleMessage.swift) is a protocol adopted by `MessageView`. If the view being presented adopts `AccessibleMessage`, SwiftMessages provides improved Voice Over. ## About SwiftKick Mobile We build high quality apps!

All rights reserved. // import UIKit /** `SwiftMessagesSegue` is a configurable subclass of `UIStoryboardSegue` that utilizes SwiftMessages to present and dismiss modal view controllers. It performs these transitions by becoming your view controller's `transitioningDelegate` and calling SwiftMessage's `show()` and `hide()` under the hood. To use `SwiftMessagesSegue` with Interface Builder, control-drag a segue, then select "swift messages" from the Segue Type dialog. This configures a default transition. There are two suggested ways to further configure the transition by setting options on `SwiftMessagesSegue`. First, and recommended, you may subclass `SwiftMessagesSegue` and override `init(identifier:source:destination:)`. Subclasses will automatically appear in the segue type dialog using an auto-generated name (for example, the name for "VeryNiceSegue" would be "very nice"). Second, you may override `prepare(for:sender:)` in the presenting view controller and downcast the segue to `SwiftMessagesSegue`. `SwiftMessagesSegue` can be used without an associated storyboard or segue by doing the following in the presenting view controller. let destinationVC = ... // make a reference to a destination view controller let segue = SwiftMessagesSegue(identifier: nil, source: self, destination: destinationVC) ... // do any configuration here segue.perform() To dismiss, call the UIKit API on the presenting view controller: dismiss(animated: true, completion: nil) It is not necessary to retain `segue` because it retains itself until dismissal. However, you can retain it if you plan to `perform()` more than once. #### Present the controller on top of all controllers If you don't know the presenter or you don't want to pass it as a source, like when you have a completely separated message controller, you can pass a `WindowViewController` as the `source` argument of the segue's initializer. By default, the window will be shown in the current window scene at `.normal` window level. However, these parameters can be customized by initializing the view controller with a `SwiftMessages.Config` that has the `SwiftMessages.Config.presentationContext` set to either `.window` or `.windowScene`: + note: Some additional details: 1. Your view controller's view will be embedded in a `SwiftMessages.BaseView` in order to utilize some SwiftMessages features. This view can be accessed and configured via the `SwiftMessagesSegue.messageView` property. For example, you may configure a default drop shadow by calling `segue.messageView.configureDropShadow()`. 2. SwiftMessagesSegue provides static default view controller sizing based on device. However, it is recommended that you specify sizing appropriate for your content using one of the following methods. 1. Define sufficient width and height constraints in your view controller. 2. Set `preferredContentSize` (a.k.a "Use Preferred Explicit Size" in Interface Builder's attribute inspector). Zeros are ignored, e.g. `CGSize(width: 0, height: 350)` only affects the height. 3. Add explicit width and/or height constraints to `segue.messageView.backgroundView`. Note that `Layout.topMessage` and `Layout.bottomMessage` are always full screen width. For other layouts, the there is a maximum 500pt width on iPad (regular horizontal size class) at 950 priority, which can be overridden by adding higher-priority constraints. See the "View Controllers" selection in the Demo app for examples. */ open class SwiftMessagesSegue: UIStoryboardSegue { /** Specifies one of the pre-defined layouts, mirroring a subset of `MessageView.Layout`. */ public enum Layout { /// The standard message view layout on top. case topMessage /// The standard message view layout on bottom. case bottomMessage /// A floating card-style view with rounded corners on top case topCard /// A floating tab-style view with rounded corners on bottom case topTab /// A floating card-style view with rounded corners on bottom case bottomCard /// A floating tab-style view with rounded corners on top case bottomTab /// A floating card-style view typically used with `.center` presentation style. case centered } /** Specifies how the view controller's view is installed into the containing message view. */ public enum Containment { /** The view controller's view is installed for edge-to-edge display, extending into the safe areas to the device edges.
