title: Add Focus to TextView in Popover
body: <p>I'll try to add the focus on a TextView inside a Popover, but I wont work at the moment. It should get the focus direct after load.</p>
  
  <p>I use:</p>
  
  <pre><code>override func viewDidAppear(animated: Bool) {
      self.textView.resignFirstResponder()
  }
  </code></pre>
  
  <p>But nothing happens. Any ideas? </p>
