        We have a live application written in XCode 6.4 which runs fine on iOS 12, 13.1, 13.1.2 but crashes on iOS 13.2 Beta.

        I have created a skeleton version of the application which does nothing except attempt to show a viewController via a navigationController.

         

        This is the code:-

         

        18- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

        19   _window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];

        20

        21    UIViewController *viewController = [[UIViewController alloc] init];

        22    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)];

        23    viewController.view = view;

        24    view.backgroundColor = [UIColor redColor];

        25

        26    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];

        27    [_window makeKeyAndVisible];

        28    _window.rootViewController = navigationController;

        29

        30   return YES;

        31}

         

        The crash happens when the rootViewController is set on the UIWindow on line 28. If lines 27 and 28 are reversed the crash happens on makeKeyAndVisible.

         

        This is the stack trace:-

        Thanks for any help,

        Update: The same code crashes in XCode 7 and XCode 8. Runs OK in 10 (targetting iOS 10). Wondering if this will be fixed by Apple or we will need to port our app to a more recent XCode?
