VoiceOver doesn't work for AVRoutePickerView wrapped in UIViewRepresentable
Hi, I've wrapped AVRoutePickerView in SwiftUI using pretty much the code given here, with a few changes: func makeUIView(context: Context) -> UIView { let routePickerView = AVRoutePickerView() // Configure the button's color. //routePickerView.delegate = context.coordinator //routePickerView.backgroundColor = .secondarySystemBackground routePickerView.tintColor = .accent routePickerView.activeTintColor = .accent // Indicate whether your app prefers video content. routePickerView.prioritizesVideoDevices = false return routePickerView } I commented out routePickerView.delegate = context.coordinator because it doesn't compile; context.coordinator is of type Void and I'm not sure how to fix that. I'm not sure if that has anything to do with the issue. Anyway, this works fine without VoiceOver; if I tap the button, I get the AirPlay popover. But in VoiceOver, if I select the button and double-tap, nothing happens… it just reads the button's accessibilityLabel again. How can I get the AirPlay popover to show in VoiceOver?

How to Receive Callbacks for UIAccessibilityAction Methods Like accessibilityPerformMagicTap()?
I’ve tried implementing the accessibilityPerformMagicTap() method in a specific UIViewController, its view, and even in AppDelegate, but I am not receiving any callbacks. I directly overrode this method in the mentioned areas, but it never gets triggered when performing a magic tap. How can I properly observe and handle the accessibilityPerformMagicTap() action?

Custom tab bar in SwiftUI
I made a (very simple) custom tab bar in SwiftUI. It's simply an HStack containing two buttons. These buttons control the selection of a paged TabView. This works well, but in VoiceOver they don't behave like the bottom tab bar or e.g. a segmented picker. Specifically, VoiceOver does not say something like "tab one of two" when the first button is focused. According to my research, in UIKit this can be accomplished by giving the container view the accessibility trait tabBar, hiding it as an accessibility element and give it the accessibility container type semanticGroup. In SwiftUI, there is also the trait isTabBar, but that does not seem to have any impact for VoiceOver. I don't see an equivalent of semanticGroup in SwiftUI. I tried accessibilityElement(children: .contain) but that also does not seem to have any impact. So, is there any way in SwiftUI to make a button behave like a tab-button in VoiceOver? And how is SwiftUI's isTabBar accessibility trait supposed to be used?

AVPlayer Visual Accessibility Issues
AVPlayer has 3 visual accessibility issues with videos out of the box: The contrast fails for the current time in the video The contrast fails for the remaining time in the video The hit area is too small for the time slider. The WCAG AA requirement is a minimum hit size of 24 x 24. The height of the hit area of the offending region is 8. Is there a known fix for any of these? This can be reproduced with this code in an app playground: import SwiftUI import AVKit import UIKit struct ContentView: View { private let video = URL(string: "https://server15700.contentdm.oclc.org/dmwebservices/index.php?q=dmGetStreamingFile/p15700coll2/15.mp4/byte/json")! @State private var player: AVPlayer? var body: some View { VStack { VideoPlayerView(player: player) .frame(maxWidth: .infinity, maxHeight: 200) } .task { player = try? await loadPlayer(video: video) } } } private struct VideoPlayerView: UIViewControllerRepresentable { let player: AVPlayer? func makeUIViewController(context: Context) -> AVPlayerViewController { let controller = AVPlayerViewController() controller.player = player controller.modalPresentationStyle = .overFullScreen return controller } func updateUIViewController(_ uiViewController: AVPlayerViewController, context: Context) { uiViewController.player = player } } private func loadPlayer(video: URL) async throws -> AVPlayer { let videoAsset = AVURLAsset(url: video) let videoPlusSubtitles = AVMutableComposition() try await videoPlusSubtitles.add(videoAsset, withMediaType: .video) try await videoPlusSubtitles.add(videoAsset, withMediaType: .audio) return await AVPlayer(playerItem: AVPlayerItem(asset: videoPlusSubtitles)) } private extension AVMutableComposition { func add(_ asset: AVAsset, withMediaType mediaType: AVMediaType) async throws { let duration = try await asset.load(.duration) try await asset.loadTracks(withMediaType: mediaType).first.map { track in let newTrack = self.addMutableTrack(withMediaType: mediaType, preferredTrackID: kCMPersistentTrackID_Invalid) let range = CMTimeRangeMake(start: .zero, duration: duration) try newTrack?.insertTimeRange(range, of: track, at: .zero) } } }

Handling Keyboard Hotkeys and Shortcuts across Multiple Languages
We have a requirement to manage the shortcuts and hotkeys in our application, and have it to be intuitive and support multi-lingual fully. The understanding that we have currently is that most universal shortcuts and hotkeys on MacOS/iOS are expressed using English/Latin characters’ – and now, when a ‘pure foreign language physical or virtual keyboard’ is the ‘input device’ – we are unclear how the user would invoke such a hotkey. Now, considering cases where other language keyboards have no Latin characters, in these environments, managing shortcuts and hotkeys becomes a rather difficult task. Taking a very simple example, the shortcut for Printing a page is Command/Control + 'P'. This can be an issue on Non English character keyboards like Arabic, where not only are there no letters for P, there is also no equivalent phonetic character as well, since the language itself does not have it. Also – when we are wanting customizability of a hotkey by the user, how would the user express ‘which is the key combination for a given action they want to perform’. So, based on these conditions, in order to provide the most comprehensive and optimal experience for the user in their own language, what is it that Apple recommend we do here, for Hotkeys/Shortcuts support in Pure Languages

Bulgarian cyrillic alphabet appears to be Russian, but should look Bulgarian
Hello So if you use the Bulgarian keyboard, you get these characters: явертъуиопюасдфгхйклшщзьцжбнмч This isn’t really right for Bulgaria, because т should look like m, and д should look like g, and other characters should look like rotated or mirrored Latin characters. E.g., г should look like a backwards s. Compare the Bulgaria Wikipedia page in Bulgarian: https://bg.m.wikipedia.org/wiki/%D0%91%D1%8A%D0%BB%D0%B3%D0%B0%D1%80%D0%B8%D1%8F with the Bulgaria Wikipedia page in Russian: https://ru.m.wikipedia.org/wiki/%D0%91%D0%BE%D0%BB%D0%B3%D0%B0%D1%80%D0%B8%D1%8F Notice that the letters are different. Anyhow, the ios Bulgarian font is just Russian Cyrillic, and that seems like an unintended bug rather than an intentional stylistic choice, basically.

Attempting to go directly to a help book page results in the main help book page being displayed instead
There is an issue with Help Books that started with the release of macOS 14.4. The issue is that when an app attempts to go directly to a Help Book page, the help viewer opens to the Help Book's main index page, rather than the specific page requested. As I investigated the issue I found that the requested page was actually part of help viewer's navigation history, and all I had to do was to click the Back navigation arrow and the requested page would be displayed. So it seems like the requested page is momentarily visited but is then (for whatever reason) quickly replaced by the main index page. Our app uses the AHGotoPage() API for directly accessing our Help Book's pages. This is the same mechanism/code that our app has used for more than a decade and has never caused us any issues. Everything works fine on macOS 14.3.0 and earlier. I've scoured the documentation and can't find any newer APIs for accessing Help pages. I've also tried various other things (e.g. reworking the code, creating new indexes for the app's Help, etc.), but none of it seems to make a difference. As far as I can tell, the issue seems to stem from some change made to the OS. So my questions are: Is this a known bug? And if so, is there any ETA on a fix? Is there something different we should be doing for newer versions of the OS (create indexes differently, use a different API, etc.)?

Why is VoiceOver’s "Content Chooser" rotor empty in my macOS app?
I'm developing a macOS app using NSView and trying to make my content navigable via VoiceOver. I'm expecting the built-in rotor category "Content Chooser" (accessed via VO + U) to list my accessible elements — just like how it shows message items in the Mail app. However, in my app, this rotor appears empty, even though: My views return proper accessibilityChildren() or accessibilityContents() with valid NSAccessibilityElements Each child has correct AXRole, AXLabel, etc. The window is key and visible VoiceOver navigation works for the elements I've also tried: Using both accessibilityChildren() and accessibilityContents() in container views Setting roles like .group, .staticText, .button, etc. Avoiding hidden elements Ensuring all elements are visible and labeled Still, "Content Chooser" rotor is empty. What exact conditions must be met for an element to appear in the "Content Chooser" rotor in a macOS app? Any Apple-specific guidance, hidden requirements, or sample code would be appreciated.

WKWebView not scrollable with a physical keyboard
Hello all. Currently I am trying to get WKWebView to scroll with a physical keyboard and it just will not work. I tried allowsKeyboardScrolling( ) and it did not work. UIWebView works but its no longer supported. Trying to get full keyboard access to work to make our app more accessible but WKWebView does not want to play nice. Has anyone else had issues trying to use WKWebView with an external keyboard, and if so did you find any solutions? Greatly appreciated!

VoiceOver cursor focus tracking
In some places of our app we make use of NSAccessibilityElement subclasses to vend some extra items to accessibility clients. We need to know which item has the VoiceOver focus so we can keep track of it. setAccessibilityFocused: does not get called when accessibility clients focus NSAccessibilityElements. This method is only called when accessibility clients focus view-based accessibility elements (i.e. when a NSView subclass gets focused). At the same time we need to programmatically move VoiceOver focus to those items when something happens. Those accessibility elements inherit from NSObject so we can't make them first responder. Is this the expected behavior? What are our options in terms of reacting to VoiceOver cursor moving around? What are our options in terms of programmatically moving the VoiceOver cursor to a different element? Here's a sample project that demonstrates the first part of the issue: https://github.com/vendruscolo/apple-rdars/tree/master/DTS12368714%20-%20NSAccessibilityElement%20focus%20tracking If you run the app, a window will show up. It contains a button and a red square. If you enable VoiceOver you'll be able to move the cursor over the red square, and a message will be logged. You'll also notice there's an extra element after the red square. That element is available to VoiceOver, however when it gets focuses, no message gets logged.

[macOS 15.4] Game Controller Background Input Capture Broken - Accessibility App No Longer Functions
Our application, https://apps.apple.com/us/app/gamecontroller-mapper/id6737088417 which maps game controller inputs to keyboard/mouse events system-wide, has stopped functioning properly after the macOS 15.4 update. Specifically, the app can no longer capture game controller inputs when running in the background, severely impacting its core functionality. Environment macOS version: 15.4 Previous working versions: All versions prior to 15.4 App type: Background utility with accessibility permissions Hardware: All game controller brands compatible with macOS Detailed Description Before macOS 15.4 Our application correctly captured game controller inputs from any brand connected to Mac and successfully translated them to keyboard/mouse events system-wide. Users could control any application (e.g., scrolling through documents in Preview using controller buttons) while our app ran in the background with the accessibility permissions granted. After macOS 15.4 The application only works when it has active focus (is in the foreground). When any other application gains focus, our app completely stops receiving or detecting any input events from the game controller while running in the background. For instance, pressing the 'down' button on the controller while another app is active results in no event being registered within our application. We've tried updating the app to work in accessory mode (in the menubar), but the issue persists. Steps to Reproduce Install our application on macOS 15.3 or earlier Grant accessibility permissions when prompted Connect a compatible game controller (e.g., Xbox or other controller) Open another application (e.g., Preview with a PDF document) Press buttons on the controller to navigate the document without touching the keyboard Expected result on 15.3: Controller inputs are translated to keyboard events, even when our app is in the background Upgrade to macOS 15.4 Repeat steps 2-5 Actual result on 15.4: Controller inputs are only translated to keyboard events when our application has focus Technical Implementation Our app uses: CGEvent.tapCreate() to create a global event tap CGEvent for simulating keyboard and mouse events GCController.extendedGamepad?.valueChangedHandler for detecting controller inputs Proper NSAccessibilityUsageDescription and appropriate entitlements GCController.shouldMonitorBackgroundEvents = true to ensure controller events continue when the app is inactive Possible Relation to Recent Changes We noticed in the macOS 15.4 Release Notes: Game Controller - Resolved Issues: Fixed: Game controllers might stop responding when accessibility features, such as Voice Over, are enabled. (141497799) We suspect this fix might have introduced a regression or intentional limitation affecting applications like ours that rely on background event simulation with game controller input. Impact This change severely impacts: Applications designed to use game controllers as assistive input devices for users who may have difficulty using traditional keyboard and mouse inputs Applications for media control, presentation navigation, and other similar use cases Users who rely on our application for accessibility purposes Questions Is this an intentional security change or an unintended side effect of the controller fix mentioned in the release notes? Are there any new APIs or alternative approaches we should implement to restore functionality? If this is a system bug, when can we expect a fix? We would greatly appreciate any guidance on how to restore our application's functionality. Thank you for your assistance.

NSAlert button background/contrast
If I use NSAlert the buttons look like this: The Cancel button has a gray background. We got complaints about the bad contrast and people pointed out that the alerts from System Settings look like this: Here the Cancel button has a white background. Unfortunately I did not find out how to make the buttons in my own alerts look like those in System Settings. Setting the button's bezel color to white did not work. Any help would be highly appreciated. Thanks. Best regards, Marc

Implementing App Clips with .NET MAUI
We have an iOS App built in .NET MAUI (Multi-platform App UI). This is a web view App. We wish to integrate APP Clips into this App. But we are unable to do it, due to less available resources online on such implementation. We do not wish to share code between .NET MAUI App and App clips. We understand it is not possible to add APP Clips without a parent swift/Xcode app. As an alternative solution we were thinking to Create a new APP in APP Store Connect using XCode/swift and integrate app clips to it. This parent app when downloaded by users will only redirect users to our MAIN .NET MAUI app to app store connect. We need to know if such apps will be approved by APPSTORE Connect? Please guide us on this. Also please do let us know if you have any other solution to integrate App clips to a .NET MAUI App
