Attempt to present UIViewController on UIViewController whose view is not in the window hierarchy

Question

Just started using Xcode 4.5 and I got this error in the console:

Warning: Attempt to present < finishViewController: 0x1e56e0a0 > on < ViewCont

Answer 1

I fixed it by moving the start() function inside the dismiss completion block:

self.tabBarController.dismiss(animated: false) {
  self.start()
}

Start contains two calls to self.present() one for a UINavigationController and another one for a UIImagePickerController.

That fixed it for me.
