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

Question

I get the following error in my console:

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

Answer 1

Make sure you have this function in your application delegate.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:    (NSDictionary *)launchOptions {
   return YES;
}

Make sure didFinishLaunchingWithOptions returns YES. If you happened to remove the 'return YES' line, this will cause the error. This error may be especially common with storyboard users.
