title: Attempt to present controller view whose view is not in the window hierarchy
body: <p>I am getting this console log when running my game with a newly inserted segue between two controller views. The game works perfectly but this log keeps repeating itself many times a second.</p>
  
  <pre><code>2015-02-10 14:58:31.496 TestGame[64786:7741533] Warning: Attempt to 
  present &lt;TestGame.SecondViewController: 0x7f86615fa0d0&gt; on 
  &lt;TestGame.GameViewController: 0x7f865b60dff0&gt; whose view is not in the
  window hierarchy!
  </code></pre>
  
  <p>Does anyone know why this is happening? Is it anything to be concerned about?</p>
  
  <p><strong>EDIT</strong> The log starts happening as soon as my second view controller (game over screen) is called when a collision is detected:</p>
  
  <pre><code>func collision(Bee:SKSpriteNode, Player:SKSpriteNode) {
      self.viewController.gameOver()
  }
  </code></pre>
