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.

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!

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?

After updating to the iOS 26 Beta version, the screenshot option within the AssistiveTouch menu has stopped working. Tapping on the "Screenshot" icon does not perform any action.

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?

Hey everyone! I am developing a screen time limit app to help people spend less time in distracting apps. It works this way: people choose unhealthy apps for them and opposite productivity apps. In the app you can exchange time spent on healthy habits to scroll or use other distracting apps. This idea was loved by social media, and the app already has 100k followers on social media without even being launched yet. So I am waiting just for one feature permission from Apple, and they have not given me any answer since I applied 3 weeks ago. There are a lot of similar apps on the market, and this feature exists in other screen time limit apps. Why is app blocking permission needed? Time Exchange Functionality: Users independently select which apps are productive and which are distracting for them. The system blocks the "negative" apps until the user accumulates enough time in the "positive" ones. This encourages healthy device usage. Full User Control: All apps to be blocked are manually selected by the user in the settings. The extension does not impose any restrictions without explicit permission. Transparency and Security: Blocking happens locally, with no data collected about app usage. We adhere to Apple’s privacy policy. Compliance with App Store Guidelines: We understand that app blocking is a sensitive feature, but in our case it: Is used for the benefit of the user (digital detox, productivity improvement). Does not interfere with system processes or other developers’ apps. Does not misuse access to APIs. My question to the forum is: Did you have similar problems, and how did you resolve them? Are there any ways to speed up the process or contact someone from the approval team directly? Should I give up and release it on Android? I am very disappointed and frustrated. Hope to get some useful tips. Thank you very much!

On recent versions of macOS, when a window is being shared (via the system screen-capture APIs), the OS sometimes shows a small "shared window" badge in the title bar. I’ve noticed that this indicator is not consistent: For some windows, the badge reliably appears when they are being shared. For other windows, the badge never appears, even though the window is actively shared. In particular, windows that use a standard system title bar seem to show the indicator more often, while windows with custom-drawn or non-standard chrome do not. My questions are: What are the exact conditions under which macOS decides to draw the “shared window” indicator in a window’s title bar? Is this strictly tied to certain NSWindow styles or masks (e.g. titled vs borderless)? Is there any API or flag I can use to detect programmatically whether a given window will display this system indicator when shared?

I’m using a 9th gen iPad, updated iPadOS 26 a few weeks ago, but I can’t use the 3D background, can’t find any way to use the 3D background. Is it a system issue or is it my iPad’s issue?

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?

Hello Albert! I am experiencing some strange bugs around DeviceActivityEvents (part of the DeviceActivity framework) on iOS 26 / iOS 26.1 / iOS 26.2 beta: When creating a DeviceActivityEvent we can assign a threshold and applicationTokens. The idea is, that after the user has spent said threshold on said apps, eventDidReachThreshold() is called. The property includesPastActivity is set to false. On iOS 26 however, it happens (quite reliably after updating to a new beta seed) quite often that eventDidReachThreshold() is called immediately (after a couple of seconds) instead of waiting for the threshold to be met. Is anyone else seeing similar issues on iOS 26 / iOS 26.1 / iOS 26.2 beta? Only workaround I have found is to ask users to revoke and re-grant Screen Time permissions. This only holds for about two weeks though or at most until the next iOS 26 beta update is installed, so it is not a permanent solution unfortunately. Feedback (incl. sysdiagnoses and sample project) is filed under: FB18061981 FB18927456 One of our users has filed their own feedback request as well: FB20817853 Thanks a lot for any help on this!

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.

I have a product for designing particle emitters, which I suspect may be of limited interest to people with limited vision. I'd still like to ensure I'm doing a good job with VoiceOver mode. There's a related, simplified sample online, if you want to look at the code As you can see from the picture below, a large part of the interface mimics Xcode's particle editor, with many value entry controls that combine up/down buttons with a tappable label. Tapping the label goes into edit mode. Apart from changing how labels are stepped through in voiceover in my app, how should I handle these stepper buttons? Is this a good place to use a Custom Rotor?

Hi, On iOS, I'd like to mark views that are inside a LazyVStack as headers for VoiceOver (make them appear in the headings rotor). In a VStack, you just have add .accessibilityAddTraits(.isHeader) to your header view. However, if your view is in a LazyVStack, that won't work if the view is not visible. As its name implies, LazyVStack is lazy so that makes sense. There is very little information online about system rotors, but it seems you are supposed to use .accessibilityRotor() with the headings system rotor (.accessibilityRotor(.headings)) outside of the LazyVStack. Something like the following. .accessibilityRotor(.headings) { ForEach(entries) { entry in // entry.id must be the same as the id of the SwiftUI view it is about AccessibilityRotorEntry(entry.name, id: entry.id) } } It kinds of work, but only kind of. When using .accessibilityAddTraits(.isHeader) in a VStack, the view is in the headings rotor as soon as you change screen. However, when using .accessibilityRotor(.headings), the headers (headings?) are not in the headings rotor at the time the screen appears. You have to move the accessibility focus inside the screen before your headers show up. I'm a beginner in regards to VoiceOver, so I don't know how a blind user used to VoiceOver would perceive this, but it feels to me that having to move the focus before the headers are in the headings rotor would mean some users would miss them. So my question is: is there a way to have headers inside a LazyVStack (and are not necessarily visible at first) to be in the headings rotor as soon as the screen appears? (be it using .accessibilityRotor(.headings) or anything else) The "SwiftUI Accessibility: Beyond the basics" talk from WWDC 2021 mentions custom rotors, not system rotors, but that should be close enough. It mentions that for accessibilityRotor to work properly it has to be applied on an accessibility container, so just in case I tried to move my .accessibilityRotor(.headings) to multiple places, with and without the accessibilityElement(children: .contain) modifier, but that did not seem to change the behavior (and I could not understand why accessibilityRotor could not automatically make the view it is applied on an accessibility container if needed). Also, a related question: when using .accessibilityRotor(.headings) on a screen, is it fine to mix uses of .accessibilityRotor(.headings) and .accessibilityRotor(.headings)? In a screen with multiple type of contents (something like ScrollView { VStack { MyHeader(); LazyVStack { /* some content */ }; LazyVStack { /* something else */ } } }), having to declare all headers in one place would make code reusability harder. Thanks

As part of apple pay implementation we are trying to create a merchant session by trying to connect to apple endpoint https://apple-pay-gateway-cert.apple.com/paymentservices/startSession. While trying to do so we are facing an error “An error occurred while sending the request. The request was aborted: Could not create SSL/TLS secure channel.” . I call the validation url by passing to a C# .Net Framework 4.8 Web API. The API setups an HttpClient with the Merchant Identity Validation Certificate found in my apple account and calls the validation url passing in the required Json Validation Object. When I call PostAsync() I get an exception with the above error message Code is working successfully on my local machine but facing this issue while deployed on Dev / Model environment for testing. We have used Azure app service for deployment and TLS version 1.2 already present here. We have used the Merchant Identity certificate that was issued and have also checked with networking and infrastructure team to make its not an issue from our side. Does anyone have any other idea what could be causing this error. Thank you, Supriya

I was trying to achieve accurate positioning with UWB on an iPhone 16 in India but couldn't find any option to enable it in the settings. I am using the Qorvo Nearby Interaction app to communicate with my custom UWB tag( DWM3001 by Qorvo).

Double-tap three fingers and drag to change zoom” should suppress “Three Finger to Drag”. Currently these gestures are triggered simultaneously, for no real reasons. I saw different behaviors for different environments, but none is desired. Current and desired behavior: This seems an issue so I filed a feedback.
