We have an C++ app which runs on multiple platforms and is build using the Qt framework. For a while we had issues with unexplainable stack traces reported by testflight users. Now I found out that if I just put throw std::runtime_error("something"); at the start of my main method the resulting crash call stack would not point to my main method. Is there something I can do (compiler flags/variables/code etc) to have the call stack from the actual throw show up in XCode and testflight?

We've been working on a SwiftUI app that randomly crashes with an exception. When navigating from one view to another, a rare exception is thrown, maybe every 1 / 200 times or so: <SwiftUI.UIKitNavigationController: 0x109888400> is pushing the same view controller instance (<_TtGC7SwiftUI32NavigationStackHostingControllerVS_7AnyView_: 0x10792d400>) more than once which is not supported and is most likely an error in the application : com.<companyName>.<appName> We haven't coded anything to directly push an instance of a view controller outside of what SwiftUI is doing. It seems to happen when the user taps on a NavigationLink view. It happens both in simulator and on device. Does anyone know what might cause this?

Starting from Xcode 15.3, previously set custom fonts can no longer be found in XIB files. Sometimes they reappear after deleting and setting the font again, but after a while, they disappear again. Can Xcode please be more stable and considerate of the user experience we developers are trying to create? I'm really frustrated.

Hi everyone! Anyone else seeing crashes like this: Fatal Exception: NSInvalidArgumentException. -[_UISnapshotWindow actualSceneBounds]: unrecognized selector sent to instance I'm encountering a crash within 3-4 seconds of launching my iOS app specifically on devices running iOS 14. The crash log indicates an NSInvalidArgumentException with the following message: `Fatal Exception: NSInvalidArgumentException 0 CoreFoundation 0x129754 __exceptionPreprocess 1 libobjc.A.dylib 0x287a8 objc_exception_throw 2 CoreFoundation 0x2cc3c -[NSOrderedSet initWithSet:copyItems:] 3 UIKitCore 0xc01ea0 -[UIResponder doesNotRecognizeSelector:] 4 CoreFoundation 0x12c2ac ___forwarding___ 5 CoreFoundation 0x12e5b0 _CF_forwarding_prep_0 6 UIKitCore 0xa918cc -[UIUndoGestureInteraction didMoveToView:] 7 UIKitCore 0x11099b4 _setInteractionView 8 UIKitCore 0x11098bc -[UIView(Dragging) addInteraction:] 9 UIKitCore 0xe9d678 -[UIEditingOverlayViewController _addInteractions] 10 UIKitCore 0x4a73e4 -[UIViewController _setViewAppearState:isAnimating:] 11 UIKitCore 0x4a7910 __52-[UIViewController _setViewAppearState:isAnimating:]_block_invoke 12 CoreFoundation 0xa75bc __NSARRAY_IS_CALLING_OUT_TO_A_BLOCK__ 13 CoreFoundation 0x2410 -[__NSArrayI enumerateObjectsWithOptions:usingBlock:] 14 UIKitCore 0x4a75ac -[UIViewController _setViewAppearState:isAnimating:] 15 UIKitCore 0x4a7dc0 -[UIViewController __viewDidAppear:] 16 UIKitCore 0x4a9964 __64-[UIViewController viewDidMoveToWindow:shouldAppearOrDisappear:]_block_invoke 17 UIKitCore 0x4a873c -[UIViewController _executeAfterAppearanceBlock] 18 UIKitCore 0xbda7c4 _runAfterCACommitDeferredBlocks 19 UIKitCore 0xbc903c _cleanUpAfterCAFlushAndRunDeferredBlocks 20 UIKitCore 0xbfcf10 _afterCACommitHandler 21 CoreFoundation 0xa25e0 __CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION__ 22 CoreFoundation 0x9c704 __CFRunLoopDoObservers 23 CoreFoundation 0x9ccb0 __CFRunLoopRun 24 CoreFoundation 0x9c360 CFRunLoopRunSpecific 25 GraphicsServices 0x3734 GSEventRunModal 26 UIKitCore 0xbca584 -[UIApplication _run] 27 UIKitCore 0xbcfdf4 UIApplicationMain 28 JobLogic 0x1d9ac4 main + 14 (main.m:14) 29 libdyld.dylib 0x1cf8 start` Here's what I've observed: The crash consistently occurs within 3-4 seconds of app launch on iOS 14 devices. I'm seeking assistance with: Understanding the Cause: Any insights into potential causes of this crash, particularly related to _[_UISnapshotWindow actualSceneBounds] and its interaction with iOS 14, would be greatly appreciated. Replication Steps: If possible, guidance on how to reliably replicate the crash on a development device would be extremely helpful for debugging purposes. Solutions: Any suggestions or known workarounds to address this specific crash or similar issues in iOS 14 would be invaluable.

My app went to review and apple rejected my app with crash logs as attached below. When i check the same, the app was running fine on my system. Couldn't figure it out the actual reason for crash. crashlog-E841C543-6D57-453B-9E3D-7106DF9D5131.txt

I'm trying to use some files within my application without transfering them to the app's file system, I've managed to do that and by using a bookmark (https://developer.apple.com/documentation/professional_video_applications/fcpxml_reference/asset/media-rep/bookmark/using_bookmark_data) I can access the same directory automatically on every new app laucnh. But if the external device gets disconnected and connected again, or the mobile device is restarted, I've noticed a change in the external device's URL and I also get an error retrieving the bookmark Error Domain=NSFileProviderErrorDomain Code=-2001 "No valid file provider found with identifier ‘com.apple.filesystems.UserFS.FileProvider’." UserInfo={NSLocalizedDescription=No valid file provider found with identifier ‘com.apple.filesystems.UserFS.FileProvider’., NSUnderlyingError=0x302a45a40 {Error Domain=NSFileProviderErrorDomain Code=-2013 "(null)"}} Is there a way that I can automatically regain access to the external device directory, or is using the UIDocumentPickerViewController the only way to access it again? Thanks!

I'm getting occasional crashes, which have not happened while running under a debugger and I haven't figured out how to reproduce. I wonder if anyone can help me glean more information from a crash report. Here's the main part. This particular report if from macOS 14.2 beta, but I've also seen it from 14.1.1.

Hello everyone, I'm programming my app and after a few days I opened and ran it on my iPhone. This app worked, but with one big problem. The problem is that the app doesn't show up in my settings and I don't know why. I didn't program/change anything. Thanks for the advice

Sorry for my rudimentary question. Environment: ・Xcode 15.3 ・C++ ・Freeglut 3.4.0 ・XQuartz 2.8.6_beta2 (already started) Current status: The following problems occurred at the time of upgrading from Xcode 14.2 to Xcode 15.3. Despite setting DISPLAY appropriately in the user environment variable, an error message " failed to open display '' " is thrown when RUN with Xcode. However, if I run the binary built with Xcode directly in the terminal, it works fine. Question: Why is the DISPLAY environment variable not being passed to Xcode internals properly when RUN in Xcode?

My Safari Web Extension app for iOS sometimes exhibits an issue where the request to SafariWebExtensionHandler sometimes doesn't return. This never happens on the simulator, and never happens when I'm actively debugging the SafariWebExtensionHandler process. It only happens on a physical device, and it only happens about 5% of the time. Note that the request happens RIGHT when the page loads (document_start), so I wonder if there's some kind of race condition happening, or a bug in iOS. No errors are thrown, and I've pared back the logic to be extremely simple, and I still see the issue persist. I'm PRETTY sure it's the SafariWebExtensionHandler because I've tested bypassing it completely (returning a dummy response from background.js), and when I do, the issue never happens. I've seen this issue posted before:, but without a resolution. SafariWebExtensionHandler.m?: - (void)beginRequestWithExtensionContext:(NSExtensionContext *)context { NSExtensionItem *response = [[NSExtensionItem alloc] init]; response.userInfo = @{ SFExtensionMessageKey: @{ @"op2": @(YES), @"op3": @(YES), @"op4": @(YES), @"op5": @(YES), @"op6":@(YES), @"op1": @(NO) } }; [context completeRequestReturningItems:@[ response ] completionHandler:nil]; } background.js (removed proprietary logic so excuse syntax errors): browser.runtime.onMessage.addListener((request, sender, sendResponse) => { console.log("Received request: ", request); if (request.action === "getUserSettings") { var payload = JSON.stringify({cmd: "getUserSettings"}); sendMessageToNative(payload, async function(response) { sendResponse(response); }); return true; } return true; }); content.js browser.runtime.sendMessage({ action: "getUserSettings" }).then((response) => { ... }); I've worked around this by waiting for a few seconds and then resending the request if I never got a response (and this workaround works!), but this results in a bad UX. So, does anyone have any tips, pointers, etc?

I am trying to download XCode apps from my Mac to my Apple Vision Pro for testing. I have tried following the instructions by going into Settings-&gt;General-&gt;Remote Devices on my Apple Vision Pro, but there my Mac does not show up as a possible connection. Per this page, I have made sure that both devices are connected to the same WiFi network, updated my Mac to Sonoma, and updated my AVP to the latest OS, and everything else that it asks for. I am able to mirror my display from my Mac but downloading apps from XCode does not work. I have also looked to enable Developer Mode by going to Settings -&gt; Privacy &amp; Security -&gt; Enable Developer Mode, but there is no option for enabling developer mode here. Per this forum, my best guess is that it is a Bonjour Protocol compatibility issue since both devices are on university wifi (WPA2), but I also tried connecting both over a hotspot which also did not work.
