title: why can't I remove some controls from storyboard - Xcode
body: <p>I added a Navigation Bar manually, it doesn't even have a navigationController. Initially I had hard time adding it, but now I have hard time deleting it.

  <p>I tried all combinations of delete, shift+delete, ctrl+delete and more. Nothing works, I really don't want it there. It actually creates 2 bars.</p>
  
  <p>Last resort would be to delete the viewcontroller and create a new one. But I'm curious on why it happens. I don't know if it's just me, but this new Xcode seems more buggy. It crashes frequently.</p>
