title: Create UISwipeGestureRecognizer on top of status bar
body: <p>I'm building a very feature-packed app at the moment and I want to implement a kind of 'go back' action triggered by a gesture recognizer. As the rest of the screen is already used the only place left is the status bar.</p>
  
  <p>So the question is, is it even possible and if so how?</p>
  
  <p>Thanks in advance!</p>
