CFPrefsPlistSource Read Error with App Group Preferences
I am encountering the following issue while working with app group preferences in my Safari web extension: Couldn't read values in CFPrefsPlistSource<0x3034e7f80> (Domain: [MyAppGroup], User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd. I am trying to read/write shared preferences using UserDefaults with an App Group but keep running into this error. Any guidance on how to resolve this would be greatly appreciated! Has anyone encountered this before? How can I properly configure my app group preferences to avoid this issue?

Handling VoiceOver Focus When Screen Changes (Push, Present, and SplitViewController)
I have some doubts about how VoiceOver handles focus when the screen updates. When a new UIViewController is pushed onto a UINavigationController or presented modally, how does VoiceOver decide which element to focus on? Is there a way to control or customize this behavior? In a UISplitViewController, when an item is selected in the primary view controller, the focus should shift to the relevant content in the secondary view controller. How can we ensure that VoiceOver correctly moves focus to the right element in the secondary panel?

TV Remote Application does not open
Updated to iOS 26 beta and now the TV remote app in the control center won’t open. I’ve tried the following: Restart phone Remove shortcut and re-add Cant find any other troubleshooting methods for this issue online so I’m guessing it’s a new problem.

Using WebSocket for BCI Click Input in VisionOS - FocusState vs. System-Level Limitations
Hi everyone, My team and I are developing an accessibility-focused VisionOS app (MindTap) as part of a university project, aiming to support individuals with Locked-In Syndrome using Brain-Computer Interface (BCI) signals to trigger interactions (e.g., tapping) within the Apple Vision Pro environment. Problem 1: Simulating Eye Tracking in Simulator We are testing onHover with Send pointer to the device under I/O > Input in the simulator, and while it mostly works (a bit laggy), we found that onHover won't function on the actual Vision Pro hardware. From what I understand, we should be using FocusState for proper gaze interaction, but testing this requires the physical device. Is there any workaround or official Apple-recommended way to simulate Focus-based gaze detection without a real Vision Pro? Problem 2: WebSocket-triggered "Click" doesn't work outside the app We successfully use WebSocket to send a custom signal (a "1" from the brain signal device) to trigger an action inside our app. However, when the user opens a third-party app like Apple News, the WebSocket-triggered "click" no longer works. We suspect this is due to sandbox restrictions or lack of system-level permissions. Is it possible in anyway to: Trigger interaction events outside the app using custom input (like BCI via Websocket)? Access system-wide click/tap simulation APIs from within VisionOS apps Integrate this with accessibility services (like Voice Control or AssistiveTouch) We'd appreciate any official guidance or tips from others building similar accessibility apps with alternative input methods in VisionOS. Thanks in advance for any insight you can provide!

Attaching procedural audio to an ARKit SCNNode
I’m developing an ARKit application where I aim to attach procedurally generated audio to detected planes in the environment. While using a static audio file with SCNAudioSource and SCNAudioPlayer works as expected, integrating procedural audio via AVAudioSourceNode does not produce any sound, nor does it generate any error messages: Stack Overflow Post Working Implementation with Static Audio File: let audioPlayer = SCNAudioPlayer(source: audioSource) node.addAudioPlayer(audioPlayer) Attempted Implementation with Procedural Audio: // Audio generation code } let audioPlayer = SCNAudioPlayer(avAudioNode: audioNode) node.addAudioPlayer(audioPlayer) In this setup, the AVAudioSourceNode successfully generates audio when connected directly to an AVAudioEngine. However, when used with SCNAudioPlayer and attached to an SCNNode, it fails to produce sound. What doesn’t work is creating some procedural audio with an AVAudioNode, as documented here: Apple docs Additionally, I explored the WWDC18 AR game project, SwiftShot, which utilizes SCNAudioPlayer(avAudioNode:). After updating it for the latest Xcode, the graphics function correctly, but the audio does not play. I also noted that the Apple documentation mentions an audioPlayerWithAVAudioNode: method, stating: Using this initializer is typically not necessary. Instead, call the audioPlayerWithAVAudioNode: method, which returns a cached audio player object if one for the specified AVAudioNode object has already been created and is available for use. However, this method does not appear to be available in Swift. Any insights or guidance on this matter would be greatly appreciated.

App Store Policy for apps that allows users to unlock contact details of person who posted content.
We have an app under development which allows musicians to unlock contact details of people who posted about an upcoming event. The musician pays a fees to unlock this contact details. Both the musician & the post owner are registered users. We will reveal the same contact info that the post owner used for account signup verification. Questions: Is this allowed? (given that we obtain consent to share contact info to other people and clearly mention this in privacy policy) If yes, will we have to use App store in-app purchase to facilitate this transaction or are we free to use a payment processor such as Stripe.

Make Accessibility Focus move to UIPickerView when tapping on UITextField (Full Keyboard Access)
I have a UITextField in my application for entering a state. If I tap on it, a UIPickerView pops up and let's the user select a state (but they can still type too). The issue relates to Full Keyboard Access. If we select the UITextField using an external keyboard, the UIPickerView appears, but in order to get to it the user has to tab through the whole view controller to get to the UIPickerView at the end. What would be nice is to a) move focus directly to the UIPickerView (have it highlighted in blue and scrollable right away with keyboard) or b) make the UIPickerView the next view that's accessible when tabbing over or using the arrow keys. I've tried using: UIAccessibility notifications (both .screenChanged and .layoutChanged, with and without a delay). This ended up only announcing the view, but didn't help with full keyboard access. Making the UIPickerView a first responder when it appears. Attempting to change the accessibilityElements order (but with so many views and views within views, this isn't really a viable option either). Pressing tab + -> (tab and right arrow button) will quickly take the user to the end of the chain of accessibility elements, in other words, to the UIPickerView. But there has to be a cleaner way of just automatically setting the focus to the UIPickerView or making it the next element by pressing the arrow key.

TestFlight access stuck on old device
Hey all — hoping someone here has dealt with this before. I’m testing an iOS app via TestFlight, and when I originally got access, I didn’t have an iPhone. So I signed in with my Apple ID on my girlfriend’s iPhone and used TestFlight there. Everything worked fine. Now I finally have my own iPhone (iPhone 16), downloaded TestFlight, signed in with the same Apple ID, and had the developer resend the invite. But when I tap "Open in TestFlight" from the invite email, I get this error: “Couldn’t load app because your Apple account has already been associated to this app.” The dev tried removing me as a tester and re-adding me, I’ve deleted TestFlight from both phones, rebooted, reinstalled, waited in between — still no luck. Even tried opening the invite link in Safari instead of Mail. Is there any way to get Apple to fully reset the association with the old device so I can use TestFlight on my new iPhone? Or do I really need to make a new Apple ID just to get around this? Any help would be huge — thanks!

iPhone screen layers
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?

TabItems in swiftUI do not scale
I have a TabView with a sample tabItem as follows: .tabItem { Label ("Import", systemImage:"doc.on.doc") .accessibilityLabel("Import Text") } But accessibility settings for large display size on does not seem to work, nor do dynamic font sizes: .tabItem { Label ("Import", systemImage:"doc.on.doc") .font(.largeTitle) .accessibilityLabel("Import Text") } The tabItems appear as a fixed size. The tab contents scale well, so this does not look pleasant at all. Is this a known bug in SwiftUI?

A Summary of the WWDC25 Group Lab - Accessibility
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.

App in Unlisted Language
I am building a language learning app for a Unlisted Primary Language. Any suggestions or heads ups? My plan is to select english and go with it. Its unfortunate that I have to list a language learning app incorrectly and a tag for that language probably does not exist across the apple system.

How to Enable Group Navigation Behavior for Custom Views in VoiceOver?
In VoiceOver, when using Group Navigation style, the cursor first focuses on the semantic group. To navigate inside the group, a two-finger swipe (left or right) can be used. This behavior works for default containers like the Navigation Bar, Tab Bar, and Tool Bar. How can I achieve the same behavior for a custom view? I tried setting accessibilityContainerType = .semanticGroup, but it only works for Mac Catalyst. Is there an equivalent approach for iOS?

Apple is lying about its commitment to accessibility on macOS
I've just received an email from Apple regarding the Global Accessibility Awareness Day and some forthcoming sessions to promote their accessibility features. What a joke. For many years, Apple refuses to provide the most basic accessibility requirement on macOS: LET USERS DISABLE ALL NON-CONSENSUAL UNSOLICITED ANIMATIONS AND OTHER UI CONVULSIONS. The scourge of animations started from macOS Lion. Yes, many of them can be, fortunately, disabled through some obscure Terminal commands (that is, if the user is lucky enough to discover them on some obscure internet resources). The "Reduce motion" control in System Settings is a fake option that doesn't do anything. And there are two most glaring accessibility violations that cannot be disabled: Scroll bar rollover highlight effect introduced on macOS 10.7.3. Every time you move the cursor over a scroll bar, the bar gets highlighted. It results in bringing the user's attention to random scroll bars for no reason whatsoever just because the cursor happens to pass over the bar at some point. HUNDREDS of unnecessary, annoying events of distraction daily! Expand/collapse animation of NSOutlineView (such as when we open/close a folder in the list view in the Finder, as well as any other app that's using outline views). It's extremely annoying, distracting, and time-wasting. All feedback submitted about this through the years remains mostly ignored (except for a few cases where I received some ridiculous replies from employees who, apparently, are barely familiar with Macs in general). Apple does NOT care about accessibility. Not only this, but it's obvious that Apple is, in fact, intentionally abusing those users who can't tolerate distracting, time-wasting animations and UI convulsions.

MAS restrictions on file read-write for desktop electron apps
We have an electron app developed for Mac. We would like to restore the user data previously saved in downloads once user installs the app from store and first launch. But MAS has restrictions with ""com.apple.security.files.downloads.read-write". We have enabled the user access in Entitlement files and request user permission before access What options can be user to auto restore the data from downlodas?
