Added a view controller in the storyboard, added a tableview in this view, and added a cell under the table, when I run the APP to jump to the page, when using the narration function, I find that when I use three fingers to swipe up or down, a sentence will be broadcast in English, I want to no longer change the accessiblity of the cell, when I perform the behavior of swiping up or down with three fingers, Broadcast how Chinese should be implemented.

I need to direct text-to-speech generated audio from my app simultaneously to a bluetooth speaker device AND to the internal iPad speaker. The app uses AVSpeechSynthesizer and several third party speech engines. How best to do this? I noticed the outputChannels property on AVSpeechSynthesizer...are there any examples of how to use this?

I need to understand the different layers that are there in the iPhone X and later OLED screens as I am designing a hardware attachment. They seem to be projecting letters and images from a different layer than the subpixel layer. Is this proprietary information, or is there a resource that explores them?

Hi everyone, I’ve been analyzing the current state of Sign Language accessibility tools, and I noticed a significant gap in learning tools: we lack real-time feedback for students (e.g., "Is my hand position correct?"). Most current solutions rely on 2D video processing, which struggles with depth perception and occlusion (hand-over-hand or hand-over-face gestures), which are critical in Sign Language grammar. I'd like to propose/discuss an architecture leveraging the current LiDAR + Neural Engine capabilities found in iPhone devices to solve this. The Concept: Skeleton-based Normalization Instead of training ML models on raw video frames (which introduces noise from lighting, skin tone, and clothing), we could use ARKit's Body Tracking to abstract the input. Capture: Use ARKit/LiDAR to track the user's upper body and hand joints in 3D space. Data Normalization: Extract only the vector coordinates (X, Y, Z of joints). This creates a "clean" dataset, effectively normalizing the user regardless of physical appearance. Comparison: Feed these vectors into a CoreML model trained on "Reference Skeletons" (recorded by native signers). Feedback Loop: The app calculates the geometric distance between the user's pose and the reference pose to provide specific correction (e.g., "Raise your elbow 10 degrees"). Why this approach? Solves Occlusion: LiDAR handles depth much better than standard RGB cameras when hands cross the body. Privacy: We are processing coordinates, not video streams. Efficiency: Comparing vector sequences is computationally cheaper than video analysis, preserving battery life. Has anyone experimented with using ARKit Body Anchors specifically for comparing complex gesture sequences against a stored "correct" database? I believe this "Skeleton First" approach is the key to scalable Sign Language education apps. Looking forward to hearing your thoughts.

While it is possible to scroll content using VoiceOver on macOS, I was not able to find any NSAccessibility APIs related to it (such as accessibilityScroll: on iOS).

The issue described here in this stack overflow conversation is still an issue today when it comes to the read back of the last 4 digits in the phone numbers for North American numbers as minus. Is there a solution other than overriding the accessibleLabel property?

Hi everyone — I’m implementing the new Hearing Device Support API described here: https://developer.apple.com/documentation/accessibility/hearing-device-support I have MFi hearing aids paired and visible under Settings → Accessibility → Hearing Devices, and I’ve added the com.apple.developer.hearing.aid.app entitlement (and also tested with Wireless Accessory Configuration: https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.external-accessory.wireless-configuration ). com.apple.developer.hearing.aid.app xxxxx but the app won't even compile with this entitlement Problem NotificationCenter.default.addObserver(...) for pairedUUIDsDidChangeNotification never fires — not on app launch, not after pairing/unpairing, and not after reconnecting the hearing aids. Because the notification never triggers, calls like: HearingDeviceSession.shared.pairedDevices always return an empty list. What I expected According to the docs, the notification should be posted whenever paired device UUIDs change, and the session should expose those devices — but nothing happens. Questions Does the hearing.aid.app entitlement require special approval from Apple beyond adding it to the entitlements file? Is there a way to verify that iOS is actually honoring this entitlement? Has anyone successfully received this notification on a real device? Any help or confirmation would be greatly appreciated.

A Summary of the WWDC25 Group Lab - Accessibility At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for Accessibility. Accessibility Nutrition Labels are a really big step forward for the experience people have on the App Store to find apps that will work for them. How should developers get started with Accessibility Nutrition Labels? A good starting point is to review the Accessibility Nutrition Label evaluation criteria on App Store Connect Help. It's a concise document, roughly 10 pages, and you can approach it section by section after the introduction. Even with prior experience using accessibility features like VoiceOver, the criteria offer valuable insights that might not be immediately apparent. For those newer to accessibility, a good entry point might be one of the visual feature labels, such as Dark Interface, which is a popular and frequently used feature. Which accessibility features can I indicate support for in Accessibility Nutrition Labels? The accessibility features covered include support for assistive technologies like VoiceOver and Voice Control, media enhancements such as captions and audio descriptions, and display accommodations. These display accommodations cover options like larger text, dark interface, differentiating without color alone, sufficient contrast, and reduced motion. With the new Accessibility Nutrition Labels, will app store reviewers validate what we select? The Accessibility Nutrition Label can be edited at any time without requiring a new app submission. However, if an app inaccurately claims feature support, App Review may contact the developer and request an update to the label or the app. Are there any updates to tools for analyzing the accessibility of our apps? Although there aren't new updates this year, continued support for Accessibility Audits is available through Xcode's built-in Accessibility Inspector. XCTest also supports accessibility audits, enabling developers to test app accessibility with every build. These audits analyze aspects like contrast, dynamic type, text clipping, element labels, and more within each view. For a deeper dive, the "Perform accessibility audits for your app" session from WWDC 2023 is a valuable resource. What are accessibility features you wish more people integrated? Accessibility features encompassing user input labels optimized for voice control, keyboard navigation and shortcuts, and dynamic type support could be more used to benefit users. What were some of the biggest accessibility challenges your team encountered while developing Liquid Glass? Apple is known for its innovation and strives to deliver a high-quality experience for everyone. Accessibility is considered a core component of visual design from the outset. For example, the Liquid Glass design inherently supports reduced transparency and increased contrast. As design continues to evolve, user feedback submitted through Feedback Assistant is invaluable. How does Liquid Glass respond to contrast? Especially for text and low contrast environments. Content legibility is a crucial aspect of the Liquid Glass design. It inherently supports accessibility features like reduced transparency and increased contrast. Your feedback during the beta period and beyond is essential to ensuring Liquid Glass provides a great experience within your apps. What are some Apple apps that stand out for their accessibility? Apps like Keynote in the iWork suite offer groundbreaking VoiceOver features to enhance creative productivity for all users. Assistive Access makes core apps such as Messages, Photos, Camera, Phone, and Music more accessible. Podcasts provides transcripts to broaden its reach, and frameworks like SwiftUI ensure that apps built with the latest UI frameworks have excellent built-in accessibility.

After replacing Big Sur OSX 11.0 with the latest 11.5, my app's AXObserverAddNotification methods fails. Here is sample code I tested from StackOverflow: https://stackoverflow.com/questions/853833/how-can-my-app-detect-a-change-to-another-apps-window AXUIElementRef app = AXUIElementCreateApplication(82695); // the pid for front-running Xcode 12.5.1 CFTypeRef frontWindow = NULL; AXError err = AXUIElementCopyAttributeValue( app, kAXFocusedWindowAttribute, &frontWindow );     if ( err != kAXErrorSuccess ){         NSLog(@"failed with error: %i",err);     } NSLog(@"app: %@  frontWindow: %@",app,frontWindow); 'frontWindow' reference is never created and I get the error number -25204. It seems like the latest Big Sur 11.5 has revised the Accessibility API or perhaps there is some permission switch I am unaware of that would make things work. What am I doing wrong?

Hello, I had submitted a question to clarify which components have accessibility APIs that trigger haptics for VoiceOver users https://developer.apple.com/forums/thread/773182. The question stems from perhaps a more direct question about specific components: do tablists and disclosures natively intend to include haptics or screen reader hint or other state or properties to indicate to screen reader users where the component begins or ends? In some web experiences there are screen reader hint text stating "end of..." or "entering" as a way to define the boundaries of these inline dialogs. I had asked about haptics in the prior thread because I do not recall natively implemented version of this except in some haptic cues but have not experienced them consistently so I am not sure if that is an intended native Swift implementation or perhaps something custom.

I'm developing a document editor for macOS using AppKit, which supports structured content such as titles and multiple heading levels—similar to what you see in the Pages app. I'm looking for a way to programmatically mark a specific substring within an NSTextView as a heading, so that VoiceOver can recognize it and announce it appropriately (e.g., by saying “heading” before reading the text). This would be similar in spirit to how NSAccessibilityLinkTextAttribute works for links. Is there an existing accessibility text attribute or recommended approach to achieve this behavior for headings? If not, I’d appreciate any guidance or suggestions on how best to implement this in a VoiceOver-friendly way. Thank you in advance for your help! Best regards,

I'm developing a calculator app and working to ensure a great experience for both VoiceOver and Braille display users. For expressions like (2+3)×5, I need two different accessibility outputs: VoiceOver (spoken): A descriptive string like “left paren two plus three right paren times five,” provided via .accessibilityValue. I'm using a custom spellOut function since VoiceOver doesn't announce parentheses—which are kind of important when doing math! Braille (symbolic): The literal math string (2+3)×5, provided using .accessibilityCustomContent("", ...), with an empty label so it’s not spoken aloud. The issue: I don’t have access to a Braille display device and Xcode’s Accessibility Inspector doesn’t seem to show the custom content. Is there any way to confirm that custom Braille content is being set correctly in Simulator or with other tools? Or…is there a "math mode" in VoiceOver that forces it to announce parentheses? Any advice or workarounds would be much appreciated! Thanks, Uhl

Hello! I'm adding VoiceOver support for my app, but I'm having an issue where my accessibility value is not being spoken. I have made a helper class that creates an NSString from a double and converts it to the user's region currency. CurrencyFormatter.m + (NSString *) localizedCurrencyStringFromDouble: (double) value { NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init]; formatter.numberStyle = NSNumberFormatterCurrencyStyle; formatter.locale = [NSLocale currentLocale]; NSString *currencyString = [formatter stringFromNumber: @(value)]; [formatter release]; return currencyString; } View Contoller self.checkTotalLabel.accessibilityLabel = NSLocalizedString(@"Total Amount", @"Accessibility Label for Total"); self.checkTotalLabel.accessibilityValue = [CurrencyFormatter localizedCurrencyStringFromDouble: total]; I'm confused on whether the value should go into the accessibility label or not. When the currency is just USD and the language is English, it's a simple fix. But when the currency needs to be converted, I'm not sure where to go from here. If anyone has any guidance, it would help me a lot! Thank you!

Hi, I’ve been reviewing the Apple Wallet provisioning documentation (Getting Started with Apple Pay In-App Provisioning_ Verification_Security_Wallet Extensions )and had a few questions regarding the color path recommendation (Green, Yellow, Orange, Red) returned during the in-app provisioning flow: Who determines the color path—is it Apple directly, the Payment Network Operator (PNO), or both? What criteria are used to determine the color path (e.g., device info, Apple ID reputation, past provisioning attempts)? At what point in the provisioning flow is the color path recommendation received? Is it included in the response after the PKAddPaymentPassRequest is submitted? Is it accessible through any specific property or callback in the delegate method? Additionally, for Orange Path with Reason Code 0G, I understand that in-app verification is not allowed and must be handled via tenured channels (e.g., SMS/email). Can you confirm if this logic still applies for requests initiated from within the issuer's iOS app? Would appreciate any clarification or pointers to related documentation.

There are several ways we are supposed to be able to control a11y (accessibility) focus in FKA (Full Keyboard Access) mode. We should be able to set up an @AccessibilityFocusState variable that contains an enum for the different views that we want to receive a11y focus. That works from VO (VoiceOver) but not from FKA mode. See this sample project on Github: https://stackoverflow.com/questions/79067665/how-to-manage-accessibilityfocusstate-for-swiftui-accessibility-keyboard Similarly, we are supposed to be able to use accessibilitySortPriority to control the order that views are selected when a user using FKA tabs between views. That also works from VO but not from FKA mode. In the sample code below, the `.accessibilitySortPriority() ViewModifiers cause VO to change to a non-standard order when you swipe between views, but it has no effect in FKA mode. Is there a way to either set the a11y focus or change the order in which the views are selected that actually works in SwiftUI when the user is in FKA mode? Code that should cause FKA to tab between text fields in a custom order: struct ContentView: View { @State private var val1: String = "val 1" @State private var val2: String = "val 2" @State private var val3: String = "val 3" @State private var val4: String = "val 4" var body: some View { VStack { TextField("Value 1", text: $val1) .accessibilitySortPriority(3) VStack { TextField("Value 2", text: $val2) .accessibilitySortPriority(1) } HStack { TextField("Value 3", text: $val3) .accessibilitySortPriority(2) TextField("Value 4", text: $val4) .accessibilitySortPriority(4) } } .padding() } }```

Hi guys, I'm facing an issue with the native interface to add a card into the wallet - does someone have some ideas on how to fix/work around that? STEPS TO REPRODUCE: Disable VoiceOver (Settings → Accessibility → VoiceOver → Off). Connect and confirm that you can navigate other iOS interfaces using an external keyboard. In any app, present a PKAddPassesViewController with a valid .pkpass file. When the Wallet “Add Pass” sheet appears, attempt to navigate using only the external keyboard (Tab/Arrow/Enter). Observe that focus does not move to the Cancel or Add buttons, and no elements receive keyboard focus. EXPECTED RESULT: All interactive elements in PKAddPassesViewController (e.g., Cancel and Add) should be fully keyboard accessible without requiring VoiceOver. Users should be able to navigate, select, and complete actions using only a hardware keyboard. ACTUAL RESULT: Keyboard navigation is not possible. No elements receive focus. Users cannot activate Cancel or Add buttons using keyboard input. The only way to interact is by touch or enabling VoiceOver, which does not satisfy keyboard accessibility requirements. IMPACT: Violates WCAG 2.1 Success Criterion 2.1.1 (Keyboard Accessible). Prevents keyboard-only users (including users with motor disabilities) from adding passes to Wallet. Affects users of external keyboards who rely on tab/arrow navigation. Creates an inconsistent accessibility experience compared to other iOS system modals.

I'm reposting here my FB17602742, submitted yesterday: The strong wording of this message comes from years of Apple ignoring the needs of users who can't tolerate UI animations and convulsions. At this point, it's clear that Apple is either intentionally harming users like me or simply doesn't care about meeting even the most basic accessibility standards on macOS. Yes, many UI animations and convulsions can, fortunately, be disabled - but not through straightforward UI controls. Instead, users are forced to look for obscure Terminal commands found scattered across the Internet. The "Reduce motion" checkbox in System Settings is simply a fake control that doesn't do anything - instead of actually disabling all UI animations and convulsions. What's worse, two of the most offensive UI animations cannot be disabled at all. Apple has consistently dismissed requests to let users disable the following UI animations: Scroll bar rollover highlight effect (introduced on macOS 10.7.3). Every time the cursor passes over a scroll bar, it gets highlighted. This draws the user's attention to random scroll bars for no reason - just because the cursor happened to pass over them. It results in HUNDREDS of unnecessary, annoying events of distraction daily!
 Expand/collapse animation of NSOutlineView (e.g., when opening/closing folders in the list view in the Finder, or any other app using outline views). This animation is extremely distracting, irritating, and time-wasting. Global Accessibility Awareness Day is approaching. Dear Apple, Please adhere to the most basic accessibility standards. Stop the needless suffering of countless users like me. Let us disable the two aforementioned UI convulsions. Thank you for your attention to the issue.

Context: We are using UIKit to provide accessibility in our app for our iOS users. Our app majorly contains documents/books that user can read. Issue: The issue is VoiceOver is skipping the lines given to it when there are some leading spaces in it. We have observed this issue in different languages. This is only happening for line granularity, other granularities seems to be working as expected. Implementation: We are using below API's to provide line content to voice over. UIAccessibilityReadingContent - accessibilityPageContent - accessibilityFrameForLineNumber - accessibilityContentForLineNumber We are creating UIAccessibilityElement objects to pass to VoiceOver and each UIAccessibilityElement implements UIAccessibilityReadingContent to provide readable content. We also use below APIs to cross element boundaries for all granular navigations. accessibilityNextTextNavigationElement accessibilityPreviousTextNavigationElement We want to know whether skipping the line when provided with leading spaces is expected or a bug in UIKit.

When I try to get the frames of a AXUIElementRef using AXUIElementCopyAttributeValue(element, (CFStringRef)attribute, &result) the frames are shifted and rotated on the iOS simulator. I get the same frames when using the Accessibility Inspector when the Max is selected as the host. When I switch the host to the iOS simulator the frames are correct. How is the Accessibility Inspector getting the correct frames? And how can I do the same in my app?
