Hello, I am developing a macOS app using AudioToolbox's MusicSequence and MusicPlayer APIs to play Standard MIDI Files. The MIDI playback works correctly and I can hear sound from the external MIDI device. However, the user callback registered via MusicSequenceSetUserCallback is never invoked during playback. Details: Callback registration returns no error. MusicPlayer is properly started and prerolled. The callback is defined as a global function with the correct @convention(c) signature. I have tried commenting out MusicTrackSetDestMIDIEndpoint to avoid known callback suppression issues. The clientData pointer is passed and correctly unwrapped in the callback. Minimal reproducible example shows the same behavior. Environment: macOS version: [Tahoe 26.2] Xcode version: [26.2] Is it expected that MusicSequenceSetUserCallback callbacks may not be called in some cases? Are there additional steps or configurations required to ensure the callback is triggered during MIDI playback? Thank you for any advic

Hi, I’m seeing an unexpected change in how XCTFail behaves in UI tests after updating Xcode. I use the following helper method: `func waitForExistance(file: StaticString, line: UInt) -> Self { if !(element.exists || element.waitForExistence(timeout: Configuration.current.predicateTimeout)) { XCTFail(couldn't find element: (element) after (Configuration.current.predicateTimeout) seconds, file: file, line: line) return self } else { return self } }` In Xcode 16.4, this worked as expected: – when an element wasn’t found, XCTFail was triggered, but the test continued running, allowing my retry logic to execute. After updating to Xcode 26.1 / 26.2 - the test now immediately aborts after XCTFail, without executing the next retry. The logs show: `t = 113.22s Tear Down t = 113.22s Terminate com.viessmann.care:81789 *** Assertion failure in -[UITests.Tests _caughtUnhandledDeveloperExceptionPermittingControlFlowInterruptions:caughtInterruptionException:whileExecutingBlock:], XCTestCase+Iss

This is a successor to: https://developer.apple.com/forums/thread/814231 I went into a slightly different direction. I generated more AI slop that use NSLock. Then I had the NSLock usage changed to Mutex usage. Now it crashes with: Task 13: EXC_BREAKPOINT (code=1, subcode=0x18d29326c) On one of the mutex closures.

Notarization submission has been stuck in In Progress status for over 15 hours with no resolution. Hi there, I am trying to roll out distribution to paid users who are unable to receive anything from me for quite some time now, and I've read that notarization is quick. But I've found myself to be under quite a delay. Wondering if I could please get some help.

I'm currently observing a problem similar to this thread https://developer.apple.com/forums/thread/737334 The difference is that this is happening after updating a system extension. Basically same error, sysextd complains it can not check that the system extension is notarized: macOS Error 3 + Error code=-67050. I think macOS (Sequoia 15.3.2 or 15.7.2 if it matters) is wrong in this case for the following reasons: when using spctl assess -t install, the system extension is reported to be correctly notarized. when restarting the Mac, the updated system extension is correctly checked and staged. if I run spctl assess before sysextd tries to check the system extension, it works. I'm currently thinking of 2 reasons why the check does not work: sysextd is somehow trying to work with a cached assessment that has become invalid after the system extension was updated. macOS needs way more time between the update of the files and the request to update the staged extension. I tried adding a 5-second delay. Thi

Hello Apple Developer Technical Support, I’m following up on case #102807413324 and submitting this as a code-level support request. We are integrating iOS Live Activities (ActivityKit + WidgetKit extension written in SwiftUI) into an Expo/React Native app. We’re seeing behavior where the Live Activity UI shown on the Lock Screen appears to “stick” to an older layout and ignores updated SwiftUI code and/or bundled assets, even after rebuilding, reinstalling, and removing existing Live Activities before testing again. Environment Device: iPhone 13 iOS: 26.2 macOS: 15.7.3 (24G419) Xcode: 16.4 (16F6) Expo SDK: 52 React Native: 0.76.9 expo-live-activity: ^0.4.2 Build type: Ad-Hoc signed IPA (EAS local build) Summary We have a WidgetKit extension target (LiveActivity.appex, bundle id: stimul8.LiveActivity) using ActivityConfiguration(for: LiveActivityAttributes.self). The extension contains multiple SwiftUI views selected via a “route” (derived from deepLinkUrl / title / subtitle), and uses images/backgrounds from

Hello, I’ve been experiencing a persistent issue in Xcode since version 26.0, and it is still present in 26.2. When using the split view to display two files side by side, the area in the top‑right corner of the window (the inspector / options panel) starts flickering continuously. This happens regardless of whether I’m using the light or dark theme, and even with the Liquid Glass effect disabled in macOS settings. None of these changes have any impact on the issue. I have already submitted a bug report through Xcode (Feedback Assistant), but the issue is still present as of today. The flickering makes the interface difficult to use and visually very distracting. I’ve attached a video to clearly show the issue. I will review the attachment at the time I publish this post. Thanks in advance for any help or feedback.
