title: Interface Builder Can't Find Any Outlets or Actions
body: <p>I think this problem has only been introduced since upgrading to XCode 6.4. I have a storyboard which was working fine (and still is), but interface builder can't see any of the outlets or actions when I right-click on one of my view controllers.</p>
  
  <p>It looks like this:</p>

  <p>I can now only create new connections to outlets/actions by command-dragging from (for example) a button, to the code file. This works, though afterwards it also shows a yellow triangle next to it.</p>
  
  <p>If I drag a standard view controller on to the storyboard, e.g. a navigation view controller, then when I right-click I CAN see all of its outlets etc, it's only with the classes which I've written.</p>
  
  <p>It does work, but it's a pain. Any ideas?</p>
