Unable to profile Metal app on M2 Ultra (profiling works on M3 Pro)
On MacBook Pro M3 14 I can profile the Metal App performance by running it, then clicking on the M icon and choosing profile after replay. On Mac Studio M2 Ultra I cannot: the profiler starts and crashes. I have tried everything including reinstalling the OS, Xcode, the Metal SDK, you name it. The app uses the Metal 4 API. The content of the replayer errorinfo report is shown at the end. Any ideas what is going on here and/or what else I can do do root cause this and fix it? FWIW, it was worse on 26.1 (Xcode just reported Metal 4 profiling not available). In 26.2 Xcode attempts to profile and invariably crashes. === Error summary: === 1x DYErrorDomain (512) - guest app crashed (512) 1x com.apple.gputools.MTLReplayer (100) - Abort trap: 6 === First Error === Domain: DYErrorDomain Error code: 512 Description: guest app crashed (512) GTErrorKeyPID: 26913 GTErrorKeyProcessName: GPUToolsReplayService GTErrorKeyCrashDate: 2026-01-09 19:22:52 +0000 === Underlying Error #1 === Domain: com.apple.gputools.MTLR

Reply to CXCallUpdate not working for outgoing calls
I try to update remoteHandle using CXCallUpdate for outgoing calls, but this works only on iOS 15 but not on 17 or 18 (16 didn't test). What's actually not working here? Are you looking at what the lock screen UI shows or what you see in other locations (particularly in the Recent call list)? There is a longstanding issue (r.126348631) where call updates aren't being displayed on the lock screen interface; however, this is purely about UI showing old data, not about the update itself completely failing. Notably: I use this handle value to implement recall by tapping on a call in the Recents tab of the system address book. But since my calls can transform from p2p to group calls, I need to update the handle value or find some other way to pass call identification info. ...I'd expect this sort of thing to work exactly the way you need/expect, regardless of what the lock screen UI shows. __ Kevin Elliott DTS Engineer, CoreOS/Hardware

Reply to Unexpected system confirmation dialog when opening a Universal Link
@DTS Engineer Thank for your answer. In summary, our issue is not straightforward. On the application site, everything functions correctly. The problem lies on the client (browser) side. I am uncertain whether a race condition or a similar condition may be the cause of this issue. All of our JavaScript code executed for this purpose is synchronous, resulting in no concurrency. The problem occurs precisely at the moment when this code executes: “window.location.assign” Therefore, there is nothing complex about it. We are simply redirecting the current page to the Universal Link. This operation works fine in most conditions but doesn't when the same Safari tab is being used. We do not see any errors in the Browser javascript console. Our flow will not function without JavaScript, as it is the only option to automatically redirect to the Universal Link without user interaction. Perhaps the issue is not with the Universal Link itself, but rather with the browser, which is unable to properly handle the li

how accessible is enough for Accessibility Nutrition Labels?
My team has a robust digital accessibility program and processes for WCAG conformance in our apps. Because of this, there are definitely accessibility defects that get caught and addressed in order of impact and business priority like any other bug. Obviously we want to aim for 100% accessibility for our users, but it's a continual work in progress as new enhancements or changes are released. I'm stuck on the appropriate measurement to indicate support. If we have 50 common tasks and the most central 10 tasks are solid but some supporting (but also common) tasks have a contrast fail or accessibleLabel missing, does that make the whole app not supporting the feature? If completing the task is the rubric there are a whole range of interpretations for that. In a complex app, I anticipate that a group like ours will have strong support for many of the Accessibility Nutrition Labels accessibility features across tasks and devices, but realistically never be 100% free of defects for a given Apple Accessibi

App is Live on App Store but Subscription Group Still “In Review” - Is This Normal?
Hi everyone, First of all, I’d like to thank the App Store Review team for the continuous effort and time they put into reviewing our apps, it’s truly appreciated. My iOS app has been approved and is already live on the App Store, however my subscription group and in-app subscription products are still marked as “Waiting for Review” in App Store Connect. I wanted to ask: Is it normal for the app binary to be approved before the subscription group? Has anyone experienced subscriptions staying in review while the app is already available? How long does subscription review usually take after the app goes live? All subscription metadata is complete (pricing, localizations, screenshots, and paywall implementation). Thanks in advance for any insights or shared experiences.

Reply to Activating a Container App from a Custom Keyboard Extension to Enable Continuous Voice Input While Preserving the Original Typing Context
I am pretty sure the change is intentional, because if you'd use the container app to gather information for a keyboard extension, you will most likely need to go with an app group container, which requires the keyboard to have full access. Having said that, if you see an appealing use case where requiring full access doesn't make sense, I’d suggest that you file a feedback report – If you do so, please share your report ID here for folks to track. Best, —— Ziqiao Chen  Worldwide Developer Relations.

Activating a Container App from a Custom Keyboard Extension to Enable Continuous Voice Input While Preserving the Original Typing Context
Project Background: I am developing a third-party custom keyboard for iOS whose primary feature is real-time voice input. In my current design, responsibilities are split as follows: 1. The container (main) app is responsible for: Audio recording Speech recognition (ASR) 2. The keyboard extension is responsible for: Providing the keyboard UI Initiating the voice input workflow Receiving transcription results via an App Group Inserting recognized text into the active text field using textDocumentProxy.insertText(_:) Intended User Flow The intended workflow is: The user is typing in a third-party app (for example, WeChat) using my custom keyboard. The user taps a “Voice Input” button in the keyboard extension. The keyboard extension activates the container app so that audio recording and ASR can begin. After recording has started, control returns to the original app where the user was typing. The container app continues running in the background, maintaining active audio recording and ASR.

UNNotificationAttachment preview intermittently missing (attachment-store URL becomes unreadable)
I have been fighting this problem for two months and would love any help, advice or tips. Should I file a DTS ticket? Summary We attach a JPEG image to a local notification using UNNotificationAttachment. iOS reports the delivered notification as having attachments=1, but intermittently no image preview appears in Notification Center. In correlated cases, the attachment’s UNNotificationAttachment.url (which points into iOS’s attachment store) becomes unreadable (Data(contentsOf:) fails) even though the delivered notification still reports attachments=1.

Clarification requested on Secure Enclave key usage across apps with shared keychain access group
During internal testing, we observed the following behavior and would appreciate clarification on whether it is expected and supported in production environments. When generating an elliptic-curve cryptographic key pair using kSecAttrTokenIDSecureEnclave, and explicitly specifying a kSecAttrAccessGroup, we found that cryptographic operations (specifically encryption and decryption) could be successfully performed using this key pair from two distinct applications. Both applications had the Keychain Sharing capability enabled and were signed with the same provisioning profile identity. Given the documented security properties of Secure Enclave, backed keys, namely that private key material is protected by hardware and access is strictly constrained by design, we would like to confirm whether the ability for multiple applications (sharing the same keychain access group and signing identity) to perform cryptographic operations with the same Secure Enclave–backed key is expected behavior on iOS.
