I get Xcode quit unexpectedly while using the SimplePlayer plug-in.
simpleplayer is the name of the app.
Xcode 6.2 only happens in simulator. IOS target 8.1 and above. App works normal without breakpoint.
This only happens when I set the breakpoint in the completion callback.

I get a crash by firebase. Only a useful information:
Corrupt NSInvocation detected. Pointer authentication.
I didn't met this type of crash before. And I found this error is related to PAC, which means Pointer Authentication. And PAC is enabled from A12 clip. Thus all devices had this crash were from iPhone XR / 11 / 12 / 13 and so on.
Below is the crash file:

I have an issue with debugging my iOS application. When the app reaches the breakpoint it stops there for a second and then the debugger crashes. (The app doesn't crash, only the debugger. A behavior similar to a device being disconnected from cable while it's in debug mode).
The print from Xcode Console:
Message from debugger: The LLDB RPC server has crashed. The crash log
is located in ~/Library/Logs/DiagnosticReports and has a prefix
'lldb-rpc-server'. Please file a bug and attach the most recent crash
log.
I checked the crash log and here's the part of the file:

error finding type for _T07Staging11AppDelegateCD
Does anybody know, what the error means?
Any help would be appreciated.
Regards
Just move your breakpoint by a line. Clean the project and try to run again, it should solve your problem.
getting lots of crashes as below in ios11: any idea what could be reason behind it. its happening in ios11 only. webkit framework is included in project.

I have updated our app for iOS 7 and added the background fetch functionality. However, i'm noticing some crashes because of this feature. After background fetch call is completed, the completion handler block is executed with either new/no data. This results in a call to 'layoutSubviews' of my custom navigation NavigationBar and sometimes app is crashing with the following stack trace. I could not reproduce this issue myself but constantly receiving these crash logs from our users. Any help would be appreciated.

When you leave your app to the background, it saves the snapshot of the current view to the memory so it could be shown when you double-click the home button.
With the iOS7 background refresh feature ((void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler), you must execute the completionHandler function after you finish executing your fetch request.
The execution of that function also triggers updates to the UI - [UIApplication _updateSnapshotAndStateRestorationArchiveForBackgroundEvent:saveState:exitIfCouldNotRestoreState:], and in your case it triggers calculating the frame for a UIWebView from a background thread.
UIWebView can be updated only from the UIThread, so to overcome this crash I would suggest to wrap the completionHandler with execution on the main thread:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler
{
void (^safeHandler)(UIBackgroundFetchResult) = ^(UIBackgroundFetchResult result){
dispatch_async(dispatch_get_main_queue(), ^{
completionHandler(result);
});
};
[someInstance doSomethingInBackground:userInfo withHandler:safeHandler];
}
And you will no longer have to worry where you invoke the completionHandler (now safeHandler) from.
