Hi All I faced up with strange issue in my app. Everything works in iOS 18.0 and lower. But after install iOS 18.1 same app from App Store crashes every time with error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Storyboard (<UIStoryboard: 0x11f6287a0>) doesn't contain a view controller with identifier 'MKCPinEntryViewControllerIdentifier'' Interesting that this view controller exist in the Storyboard. First call in app: dispatch_async(dispatch_get_main_queue(), ^{ //No authentication, needs login view controller popped. UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; PinEntryViewController *pinViewController = [storyboard instantiateViewControllerWithIdentifier:@"PinEntryViewControllerIdentifier"]; pinViewController.delegate = self; pinViewController.entryType = PinEntryTypeEnter; [self.presentationContext presentViewController:pinViewController animated:YES completion:nil]; }); works good. But second call in other place after 5 seconds: dispatch_async(dispatch_get_main_queue(), ^{ UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; PinEntryViewController *pinViewController = [storyboard instantiateViewControllerWithIdentifier:@"PinEntryViewControllerIdentifier"]; pinViewController.delegate = self; [self.presentationContext presentViewController:pinViewController animated:YES completion:nil]; }); crash the app with Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Storyboard (<UIStoryboard: 0x11f6287a0>) doesn't contain a view controller with identifier 'MKCPinEntryViewControllerIdentifier'' *** First throw call stack: (0x1841b47cc 0x1814872e4 0x186d9c140 0x1063d692c 0x10301ec08 0x104370a30 0x10437271c 0x104382de8 0x1043829a4 0x184188204 0x184185440 0x184184830 0x1d01641c4 0x186ceaeb0 0x186d995b4 0x10667fe3c 0x1a9b72ec8) libc++abi: terminating due to uncaught exception of type NSException And issue not only with this view controller. issue with all in that storyboard. At start up instantiateViewControllerWithIdentifier works good with all view controllers identifiers. But on second call in other places in the app - all crash with same error Reproduce in real device with iOS18.1 only. Simulators and devices with iOS 18.0 works well. Could someone help me, what's wrong with the app?
