We have tested the app on iPhone X,iPhone XS for these devices the view is getting displayed properly but for iPhone XR only Navigation controller hides.
Following is the code we have written
homescreen = [[HomeScreenViewController alloc]initWithNibName:@"HomeScreenViewController" bundle:nil];
UINavigationController *homeNavigationController = [[UINavigationController alloc] initWithRootViewController:homescreen];
self.window.rootViewController = homeNavigationController;
