Reply to Issue with App Crashing After Download from App Store
Thank you for the post and detailed description of the issue. I have checked both versions of the app on the App Store and TestFlight. Both versions have the same version 4.0.1 and the same build number 340. Therefore, both versions appear to be the same app. However, the crash files indicate that there is a part in your code that calls abort. Unfortunately, since it is your code and symbols, I cannot pinpoint the exact location of the crash at this time. It appears that frame 8 is the culprit. I recommend downloading the app from TestFlight and using your Xcode with your symbols to identify the crash or abort. I am happy to assist you in loading your app symbols to diagnose the issue. 8 dbMobil_DevExpress 0x106d60b88 Please let me know how I can help. However, I believe that if you use Xcode, connect the device, and debug the app, you will be able to resolve the issue quickly. I hope this information is helpful to you. Albert Pascual

Reply to [iOS 26] [CallKit] [SDK 26] Application got crashed while App was Inactive
The crash log, an IPS file, indicates a crash occurred at a specific time, with the exception backtrace pointing to _terminateAppIfThereAreUnhandledVoIPPushes. So, this crash ONLY occurs for one reason, which is that your app received a voip push and failed to report a new incoming call, as the API contract requires. There's no other way this crash can occur. However, cross-reference with the SysDiagnose logs, there is no corresponding process or activity for the application at the reported crash time. The app was not active, nor was it woken up by any event. I'm not sure where you were looking, but there is plenty of syslog data about the crash. Starting from the crash log, the crash occurred at: Date/Time: 2025-08-29 16:21:32.6696 +0530 ... Terminating Process: [283] And the time and pid (283) match up with the crash log embedded the system log archive: 2025-08-29 16:21:32.669000+0530 283 : { In terms of the general flow of th

Reply to iOS 18 启动崩溃 main_executable_path_missing
We’re still seeing a dyld crash at app startup on iOS 18.1.1 (22B91). The crash happens before our app binary is even mapped (main_executable_path_missing in crash log). Device: iPhone 12 Pro (iPhone13,3) iOS: 18.1.1 (22B91) Distribution: App Store build Feedback filed: FB20068209 Restaring the iPhone sometimes resolves it, but it’s happening in production and has been reported by multiple users. To what version (if any) should we recommend users to upgrade until this is solved?

tvOS 26 + Xcode 26 debugger won't launch
I have been using tvOS 18 and Xcode 26 all summer without issue but since updating the tv to the latest tvOS 26 beta I am now unable to attach to debug builds. When using the Run button in Xcode the build completes, the tv screen goes black and then I see a warning in Xcode: Launching App Name is taking longer than expected. Do you want to continue to wait? LLDB is likely reading from device memory to resolve symbols. If I continue to wait after around 5 mins, in the Xcode console, I see: warning: libobjc.A.dylib is being read from process memory. This indicates that LLDB could not find the on-disk shared cache for this device. This will likely reduce debugging performance. But the process on the tv hangs indefinately. Hitting stop in Xcode disconnects the debugger but the app then finishes launching successfully on the TV. Trying to use Debug > Attach to process > [App Name] once it is running also just hangs the app and waits until stopped. When stopping the hung debugger I see an Xc

Reply to Network Extension App for MacOS with 3 Extensions
We do allow you to embed multiple network extensions in the same app. That’s true on all our platforms, although the mechanics vary based on whether you’re using a system extension (sysex) or an app extension (appex). For more info about what packaging is supported on what platforms, see TN3134 Network Extension provider deployment. It sounds like you’re using a sysexes, and that presents a decision point: You can have multiple independent sysex, each with a single NE provider. Or you can have a single sysex with multiple NE providers. The latter is generally easier to wrangle. In that case you have a single sysex target with multiple NE provider subclasses linked into the resulting executable, and then list all of those in the NEProviderClasses dictionary in your sysex’s Info.plist. IMPORTANT If you set things up this way there’s a single sysex process and all of your NE providers run within that. This has pros (you can share data between them) and cons (if one crashes, they all crash). Of

Reply to Native Crash - Unknown Function (/usr/lib/system/libsystem_kernel.dylib) Unknown Function (/usr/lib/system/libsystem_kernel.dylib)
Yes! If you Quick Look that in the Finder, you’ll get a human readable version of it. My comments below are based on that. The presence of the Last Exception Backtrace section indicates that your app crashed due to an unhandled language exception. Looking at the associated backtrace I see this: Last Exception Backtrace: 0 CoreFoundation … __exceptionPreprocess + 164 1 libobjc.A.dylib … objc_exception_throw + 88 2 CoreFoundation … +[NSObject(NSObject) _copyDescription] + 0 3 CoreFoundation … ___forwarding___ + 1492 4 CoreFoundation … _CF_forwarding_prep_0 + 96 5 UnityFramework … 0x10b164000 + 26948776 6 UnityFramework … 0x10b164000 + 26953748 7 UnityFramework … 0x10b164000 + 26918904 8 UnityFramework … 0x10b164000 + 26917296 9 UnityFramework … 0x10b164000 + 26902496 10 UnityFramework … 0x10b164000 + 27452572 11 libdispatch.dylib … _dispatch_call_block_and_release + 32 Frame 11 is Dispatch calling a block on a queue.

Network framework crashes on fork

Core Data initialization causes app to deadlock on startup
Users have been reporting that the TestFlight version of my app (compiled with Xcode 26 Beta 6 17A5305f) is sometimes crashing on startup. Upon investigating their ips files, it looks like Core Data is locking up internally during its initialization, resulting in iOS killing my app. I have not recently changed my Core Data initialization logic, and it's unclear how I should proceed. Is this a known issue? Any recommended workaround? I have attached the crash stack below. Thanks! crash_log.txt
