title: Setting rootViewController crashes on iOS 8
body: <p>It all worked OK in iOS 6 and 7. Without any change made now it is crashing in iOS 8.
  Declared in AppDelegate.h:</p>
  
  <pre><code>IBOutlet UISplitViewController *splitViewController;
  </code></pre>
  
  <p>in AppDelegate.m: [application didFinishLaunchingWithOptions]:</p>
  
  <pre><code>[self.window setRootViewController:splitViewController];
  </code></pre>
  
  <p>It crashes here with the message EXC_BAD_ACCESS (code=2). </p>
  
  <p><strong>Edit</strong>: I am checking splitViewController's value, it is not nil.</p>
  
  <p>Please share with me any info that could be relevant. Thanks!</p>
