title: Xcode 7 - custom UITableViewController no longer drawing in storyboard
body: <p>I created a UITableViewController in my storyboard. Added all the table cells, etc. and set it up with a Custom UITableViewController. But now, when I open my Storyboard, the image of the ViewController no longer draws. There is a segue drawn from the calling controller, but it just points to empty space.</p>
  
  <p>The original controller entry can be found on the left in the "document outline" with all of its subviews and constraints intact, and I can run the app on my iPad without a problem. </p>
  
  <p>Has anyone seen this behavior before and is there a recovery action I can take to get the controller to draw in the storyboard?</p>
