How to disable the default focus effect and detect keyboard focus in SwiftUI?
I’m trying to customize the keyboard focus appearance in SwiftUI. In UIKit (see WWDC 2021 session Focus on iPad keyboard navigation), it’s possible to remove the default UIFocusHaloEffect and change a view’s appearance depending on whether it has focus or not. In SwiftUI I’ve tried the following: .focusable() // .focusable(true, interactions: .activate) .focusEffectDisabled() .focused($isFocused) However, I’m running into several issues: .focusable(true, interactions: .activate) causes an infinite loop, so keyboard navigation stops responding .focusEffectDisabled() doesn’t seem to remove the default focus effect on iOS Using @FocusState prevents Space from triggering the action when the view has keyboard focus My main questions: How can I reliably detect whether a SwiftUI view has keyboard focus? (Is there an alternative to FocusState that integrates better with keyboard navigation on iOS?) What’s the recommended way in SwiftUI to disable the default focus effect (the blue overlay) and replace it with a custom border? Any guidance or best practices would be greatly appreciated! Here's my sample code: import SwiftUI struct KeyboardFocusExample: View { var body: some View { // The ScrollView is required, otherwise the custom focus value resets to false after a few seconds. I also need it for my actual use case ScrollView { VStack { Text("First button") .keyboardFocus() .button { print("First button tapped") } Text("Second button") .keyboardFocus() .button { print("Second button tapped") } } } } } // MARK: - Focus Modifier struct KeyboardFocusModifier: ViewModifier { @FocusState private var isFocused: Bool func body(content: Content) -> some View { content .focusable() // ⚠️ Must come before .focused(), otherwise the FocusState won’t be recognized // .focusable(true, interactions: .activate) // ⚠️ This causes an infinite loop, so keyboard navigation no longer responds .focusEffectDisabled() // ⚠️ Has no effect on iOS .focused($isFocused) // Custom Halo effect .padding(4) .overlay( RoundedRectangle(cornerRadius: 18) .strokeBorder( isFocused ? .red : .clear, lineWidth: 2 ) ) .padding(-4) } } extension View { public func keyboardFocus() -> some View { modifier(KeyboardFocusModifier()) } } // MARK: - Button Modifier /// ⚠️ Using a Button view makes no difference struct ButtonModifier: ViewModifier { let action: () -> Void func body(content: Content) -> some View { content .contentShape(Rectangle()) .onTapGesture { action() } .accessibilityAction { action() } .accessibilityAddTraits(.isButton) .accessibilityElement(children: .combine) .accessibilityRespondsToUserInteraction() } } extension View { public func button(action: @escaping () -> Void) -> some View { modifier(ButtonModifier(action: action)) } }

The camera preview screen cannot be previewed in full screen
I downloaded the official camera sample code(https://developer.apple.com/tutorials/sample-apps/capturingphotos-camerapreview )it's a .swiftpm package and created a SwiftUI project. I copied the official sample code into this new project, build it, and ran it on an iPhone 13 for testing. I found that there were black empty areas on the top and bottom of the application interface, which means that the application interface cannot be previewed in full screen. I have tried many methods but cannot preview in full screen. How can I modify the code?

AXSpeech Thread Crash SEGV_ACCERR
Hi everyone, I've encountered a rare and strange crash in my app that I can't consistently reproduce. The crash seems to occur deep within Apple's internal frameworks, and I can't pinpoint which line of my own code is causing it. Here's the crash stack trace: #44 AXSpeech SIGSEGV SEGV_ACCERR 0 CoreFoundation ___CFCheckCFInfoPACSignature + 4 1 CoreFoundation _CFRunLoopSourceSignal + 28 2 Foundation _performQueueDequeue + 492 3 Foundation ___NSThreadPerformPerform + 88 4 CoreFoundation ___CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 5 CoreFoundation ___CFRunLoopDoSource0 + 176 6 CoreFoundation ___CFRunLoopDoSources0 + 340 7 CoreFoundation ___CFRunLoopRun + 828 8 CoreFoundation _CFRunLoopRunSpecific + 608 9 Foundation -[NSRunLoop(NSRunLoop) runMode:beforeDate:] + 212 10 TextToSpeech _TTSCFAttributedStringCreateStringByBracketingAttributeWithString + 776 11 Foundation ___NSThread__start__ + 732 12 libsystem_pthread.dylib __pthread_start + 136 Sometimes, instead of line 10 referencing _TTSCFAttributedStringCreateStringByBracketingAttributeWithString, it shows: 10 TextToSpeech LogWarning(char const*, ...) + 7288 Has anyone experienced a similar issue or know what might be triggering this crash? Any guidance on how to investigate or resolve this would be greatly appreciated. Thank you!

Assistive Access Bugs
Hi! I have noticed a few glitches as well as some overall unfortunate cons with the assistive access mode. Alarms, timers, stopwatch, etc. do not sound or alert. However, I have an infant monitor app and I do get that sound alert so I know it is possible.. do I need to download a separate alarm app for it to work? Cannot make FaceTime calls with favorite contacts. Find My iPhone cannot jump to the maps app. Camera cannot zoom in or out. Photos cannot be deleted, edited, or shared in a shared album in the photos app. Photos/videos cannot be sent in messages. Spotify cannot be accessed from the lock screen. Apps do not stay open if you lock the phone screen or leave it on too long without touching the screen (auto locks). There is no flashlight option. I downloaded an app to have this feature but without being touched the screen will lock which shuts off the flashlight feature in the app until I unlock the phone again.

Programmatically force VoiceOver to read parentheses for math expressions
How can I force VoiceOver to read parentheses for math expressions like this: Text("(2+3)×4") // VoiceOver: Two plus three, times four I’m looking for a way to have VoiceOver announce parentheses (e.g. “left paren”, “right paren”) without relying on NumberFormatter.Style.spellOut or .speechAlwaysIncludesPunctuation(), as both have drawbacks. Using .spellOut breaks braille output and Rotor › Characters menu by turning numbers and symbols into words. And .speechAlwaysIncludesPunctuation() makes VoiceOver overly verbose—for example, it reads “21” as “twenty hyphen one.” Is there a better way to selectively announce specific punctuation like parentheses while keeping numbers and symbols intact for braille and Rotor use?

Guided Access Mode From Background
My team is designing an app for retail associates that need to share managed iPads. We keep the app in Guided Access mode on our login app until an auth token is obtained. Then the iPad is opened for general use. Upon signout we need to re-enter guided access mode and we can do this via manual signout easily. But with idle signout, ie after 60 minutes of inactivity, we need to be able to make a call from the background (in a locked state even) and sign out the user, clear the pin code and enter single app mode before restarting. So that hopefully once the device restarts, we have the app in a locked state again until the next user provides credentials that can obtain a new auth token. We are struggling to see if this is even possible. Our bosses will be displeased if we tell them it isn't. So anybody with any tips would be very appreciated.

VoiceOver does not focus App Store subscription modal when shown via AppStore.showManageSubscriptions(in:)
Description When calling AppStore.showManageSubscriptions(in:), the system modal for managing subscriptions appears visually. However, it is not automatically focused by VoiceOver, and in some cases, VoiceOver still allows interaction with elements in the underlying view controller, such as buttons and labels. This creates confusion and violates accessibility expectations. Steps to Reproduce 1. In a UIKit app, present the system subscription sheet via AppStore.showManageSubscriptions(in:). 2. Ensure VoiceOver is enabled on the device. 3. Observe the focus behavior when the modal appears. 4. Try swiping right/left — VoiceOver continues to announce items in the presenting view controller. Expected Result The modal should automatically take VoiceOver focus, and all elements behind it should be non-accessible until dismissed. Actual Result VoiceOver continues to focus and interact with elements behind the presented modal. Notes • Tested on iOS 18.5 • Reproducible on device • Using Swift/UIKit (not SwiftUI)

SwiftUI List Accessibility VoiceOver
I have been working on a feature, where I have a List in SwiftUI with previous and next data loading, user can scroll up and down to load previous/next page data. Recently, I faced one accessibility issue while testing voice-over, when user lands on the listing screen and swipe across the screen from navigation and when focus comes on list it should highlight the first item visible. But when user swipes back: Should it load the previous data and announce the previous item or it should go back to the navigation items? If it loads the previous item, what if the user wants to go to the navigation to switch to other actions and vice-versa? Did anyone come across this kind of issue? What can be the standard expected behavior in this case if list has both previous and next page scroll? I different tried gestures https://support.apple.com/en-in/guide/iphone/iph3e2e2281/ios, but it isn't working

AXChildren does not get all children
I'd like to add borders to all buttons in the iOS simulator from my Mac app. First I get the simulator window. Then I access the children of all AXGroup and if it's a button or a static text, I add a border. But for some buttons this does not work. In the example image the NavigationBarButtons are not found. I guess the problem is, that for some AXGroup the children array access with AXChildren is empty. Here is some relevant code: - (NSArray<DDHOverlayElement *> *)overlayChildrenOfUIElement:(AXUIElementRef)element index:(NSInteger)index { NSMutableArray<DDHOverlayElement *> *tempOverlayElements = [[NSMutableArray alloc] init]; NSLog(@">>> -----------------------------------------------------"); NSString *role = [UIElementUtilities roleOfUIElement:element]; NSRect frame = [UIElementUtilities frameOfUIElement:element]; NSLog(@"%@, role: %@, %@", element, role, [NSValue valueWithRect:frame]); NSArray *lineage = [UIElementUtilities lineageOfUIElement:element]; NSLog(@"lineage: %@", lineage); NSArray<NSValue *> *children = [UIElementUtilities childrenOfUIElement:element]; if (children.count < 1) { NSLog(@"NO CHILDREN"); } for (NSInteger i = 0; i < [children count]; i++) { NSValue *child = children[i]; AXUIElementRef uiElement = (__bridge AXUIElementRef)child; NSString *role = [UIElementUtilities roleOfUIElement:uiElement]; NSRect frame = [UIElementUtilities frameOfUIElement:uiElement]; NSLog(@"----%@, role: %@, %@", child, role, [NSValue valueWithRect:frame]); } NSLog(@"<<< -----------------------------------------------------"); for (NSInteger i = 0; i < [children count]; i++) { NSValue *child = children[i]; AXUIElementRef uiElement = (__bridge AXUIElementRef)child; NSString *role = [UIElementUtilities roleOfUIElement:uiElement]; NSRect frame = [UIElementUtilities frameOfUIElement:uiElement]; NSLog(@"%@, role: %@, %@", child, role, [NSValue valueWithRect:frame]); if ([role isEqualToString:@"AXButton"] || [role isEqualToString:@"AXTextField"] || [role isEqualToString:@"AXStaticText"]) { NSString *tag = [NSString stringWithFormat:@"%ld%ld", (long)index, (long)i]; NSLog(@"tag: %@", tag); DDHOverlayElement *overlayElement = [[DDHOverlayElement alloc] initWithUIElementValue:child tag:tag]; [tempOverlayElements addObject:overlayElement]; } else if ([role isEqualToString:@"AXGroup"] || [role isEqualToString:@"AXToolbar"]) { [tempOverlayElements addObjectsFromArray:[self overlayChildrenOfUIElement:uiElement index:++index]]; } else if ([role isEqualToString:@"AXWindow"]) { [self.overlayWindowController setFrame:[UIElementUtilities frameOfUIElement:uiElement]]; [tempOverlayElements addObjectsFromArray:[self overlayChildrenOfUIElement:uiElement index:index]]; } } return [tempOverlayElements copy]; } For some AXGroup the children are found. For some they are empty. I cannot figure out why. Does anyone have an idea what I'm doing wrong?

DUNS Number
Hello, I’m in the process of enrolling my business (Carzo Rent A Car, Prishtine, Kosovo) in the Apple Developer Program, but I have been waiting for my D-U-N-S number to be issued. I submitted the request to Dun & Bradstreet on July 28, 2025 (Case #9142648) and have only received a system-generated email with a tracking ID (#9086421). There has been no further update. My questions are: Is there a way for Apple to expedite or provisionally approve my enrollment while the D-U-N-S number is pending? How long does Apple typically wait for D&B updates before the enrollment is affected? Are there any alternative steps I can take to avoid further delays? Thank you for your guidance.

accessibilityActivationPoint Not Working When Set Directly on UITableViewCell
I’m trying to set the accessibilityActivationPoint directly on a UITableViewCell so that VoiceOver activate on a specific button inside the cell. However, this approach doesn’t seem to work. Instead, when I override the accessibilityActivationPoint property inside the UITableViewCell subclass and return the desired point, it works as expected. Why doesn’t setting accessibilityActivationPoint directly on the cell work, but overriding it inside the cell does? Is there a recommended approach for handling this scenario? The following approach works, override var accessibilityActivationPoint: CGPoint { get { return convert(toggleSwitch.center, to: nil) } set{ super.accessibilityActivationPoint = newValue } } but setting accessibility point directly not works private func configureAccessibility() { isAccessibilityElement = true accessibilityLabel = titleLabel.text accessibilityTraits = .toggleButton accessibilityActivationPoint = self.convert(toggleSwitch.center, to: self) accessibilityValue = toggleSwitch.accessibilityValue }

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?
