title: iOS app crashes when device is tilted to landscape orientation
body: <p>Working on an app for iOS 8 using Swift. It is only supposed to be supported in portrait orientation mode.</p>
  
  <p>The app runs without issue if it starts in portrait mode and does not get tilted such that the device is in landscape mode. It also runs without issue if the device STARTS in landscape mode and either stays in this mode or is tilted to portrait mode.</p>
  
  <p>When the phone moves from portrait to landscape mode the app crashes every time. The error is of type EXC_BAD_ACCESS and gives an address. The UI highlights the first line of the <code>AppDelegate</code> class. </p>
  
  <p>info.plist has been changed to express the fact that only portrait mode is supported. In addition, I tried overriding the method <code>shouldAutorotate()</code> in the root view controller. However, I think this is a memory issue.</p>
  
  <p>What information do I need to find a solution for this issue? Can anyone point me towards resources for dealing with memory issues in iOS 8?</p>
