title: Dragging connections from a storyboard to the app delegate
body: <p>I can't seem to find this anywhere, but I'm having issues trying to create reference outlets in my storyboard to my app delegate for <code>UIWindow</code> and <code>UIViewController</code>. The <code>UIViewController</code>s are from a <code>UISplitViewController</code>. From examples I've seen that use a xib file rather than a storyboard, the <code>IBOutlet</code>s seem to be made by "clicking and dragging".</p>
  
  <p>I'm completely lost on the issue as Xcode won't let me drag any outlet into my app delegate. If you could help point out what I'm doing wrong, I'd greatly appreciate it.</p>
