[UIApplication _runWithMainScene:transitionContext:completion:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3505.16/UIApplication.m:3294 2015-09-19 12:16:48.889 OrderEm[4102:68071] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Application windows are expected to have a root view controller at the end of application launch'

  -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  {
 self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]autorelease];


 Login *login=[[[Login alloc]initWithNibName:@"Login~iPad" bundle:nil]autorelease];

        [self.window setRootViewController:login];
       // self.window.rootViewController = login;
        [self.window makeKeyAndVisible];

        return YES;
 }

My login view didload and viewwillappear methods called after that getting this crash.

This fixed it for me

Applications are expected to have a root view controller at the end of application launch

I have encountered this error, returns this error in the simulator, there is no problem on the real machine.
