Crash in libicucore via NSDateFormatter dateFromString: on iOS 26.2
Introduction: I’m encountering a consistent crash in production on iOS 26.2 (build 23C55). The crash occurs deep within libicucore when calling [NSDateFormatter dateFromString:]. Crash Summary: Exception Type: SIGSEGV (SEGV_ACCERR) Fault Address: 0xffffffff Thread: Crashed on Main Thread (Thread 0) Library: libicucore.A.dylib Code Snippet: The crash is triggered by the following method. It converts a string to an NSDate using a specific format and locale: // 获取日期date - (NSDate *)getDateWithTime:(NSString *)time formatter:(NSString *)formatterStr { NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; [formatter setDateFormat:formatterStr]; formatter.timeZone = [NSTimeZone timeZoneWithName:@Asia/Shanghai]; formatter.locale = [[NSLocale alloc] initWithLocaleIdentifier:@en_US_POSIX]; return [formatter dateFromString:time]; } Backtrace: Here is the relevant part of the crash report: Incident Identifier: E24485B6-C53E-4115-A6CF-A7E4A952AD50 CrashReporter Key: 21FAC1CF-F56B-409A-98AA-351D3D2EB06C Ha

Universal Control Copy Paste Issue
I have a Macbook and a Mac Mini at home, connected with Universal Control. When I copy-paste some big group of files (say, 250GB of photos) the OS creates a copy of all those files under shared-clipboard in Library (filling up disk space in short time) even if I don't even move the cursor to other devices. It doesn't even delete those files and clear up disk space even after I paste it. This is a design flaw, it shouldn't be like this.

# [CRITICAL] Metal RHI Memory Leak - Resource exhaustion vulnerability (CWE-400) - Bug Report
[CRITICAL] Metal API Memory Leak - Heap Memory Never Released to OS (CWE-400) Security Classification This issue constitutes a resource exhaustion vulnerability (CWE-400): Aspect Details Type Uncontrolled Resource Consumption CWE CWE-400 Vector Local (any Metal application) Impact System instability, denial of service User Control None - no mitigation available Recovery Requires application restart Summary Metal heap allocations are never released back to macOS, even when the memory is entirely unused. This causes continuous, unbounded memory growth until system instability or crash. The issue affects any application using Metal API heap allocation. This was discovered in Unreal Engine 5, but reproduces in a completely blank UE5 project with zero application code - confirming this is Metal framework behavior, not application-level.

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

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 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

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.

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.
