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];2021 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];2526 UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];27 [_window makeKeyAndVisible];28 _window.rootViewController = navigationController;2930 return YES;31}The crash happens when the rootViewController is set on the UIWindow on line 28. If lines 27 and 28 are reverse
