Change Log

All notable changes to this project will be documented in this file.

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 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.
  2. 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.
  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 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.

// 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:

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 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 readme.
  • Update nib files to be more visually consistent with iPhone X:
    • Introduce CornerRoundingView, 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 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:

    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

Bug Fixes

  • Undo change that broke MessageView class reference on nib files copied out of the SwiftMessages framework.

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.

    // 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

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

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

Bug Fixes

  • Fix an issue where rapidly showing and hiding messages could result in messages becoming orphaned on-screen.

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

Bug Fixes

  • Fix regression where the UI was being blocked when using DimMode.none.

3.3.0

Features

3.2.1

Bug Fixes

  • Fix infinite loop bug introduced in 3.2.0.

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

Bug Fixes

  • Fix memory leak of MessageViews.

3.1.4

Bug Fixes

  • Fixed an issue where UIKit components were being instantiated off the main queue.

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

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

Features

  • Added a view case to presentationContext for displaying the message in a specific container view.

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

Features

  • Add ignoreDuplicates option to SwiftMessages.Config to specify whether or not to ignore duplicate Identifiable message views.

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

Improvements

  • Enable automatic provisioning on framework target

3.0.0

Breaking Changes

  • Support for Swift 3.0.

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

Bug Fixes

  • Fix #16 Preserve status bar visibility when displaying message in a new window.

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

Bug Fixes

  • Fix Carthage-related issues.

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

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

Improvements

  • Remove the iconContainer property from MessageView.

Bug Fixes

  • Fix constraints generated by BaseView.installContentView().

1.0.2

Features

  • Add support for specifying an IconStyle in the MessageView.configureTheme() convenience function.

1.0.1

  • Add code comments.

1.0.0

  • Initial release.
