title: "UIRequiresFullScreen" (info.plist)
body: <p>I'm building an app that can't appear in Slide Over or Split View. So, I added the new key "UIRequiresFullScreen" in my info.plist. </p>
  
  <p>It works fine, but something weird happens when I try to access <code>UIScreen.mainScreen().bounds</code> in <code>viewWillTransitionToSize</code> method:</p>
  
  <p><strong>UIRequiresFullScreen => NO</strong></p>
  
  <pre><code>override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
      print(UIScreen.mainScreen().bounds)
  
      // iPad Pro Simulator, transitioning between Portrait to Landscape
      // prints: (0.0, 0.0, 1366.0, 1024.0)
  }
  </code></pre>
  
  <p><strong>UIRequiresFullScreen => YES</strong></p>
  
  <pre><code>override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
      print(UIScreen.mainScreen().bounds)
  
      // iPad Pro Simulator, transitioning between Portrait to Landscape
      // prints: (0.0, 0.0, 1024.0, 1366.0)
  }
  </code></pre>
  
  <p>What's happening??</p>
  
  <p><strong>OBS:</strong> I'm using iOS 9 SDK, supporting all orientations, using Size Class and a launch storyboard, so my last hope is this <code>UIRequiresFullScreen</code> key.</p>
