title: Storyboard not updating visually
body: <p>The problem I'm having is that my storyboard stopped showing changes on the views. The changes that don't reflect are changing constraints, changing views attributes or adding new views to any view controller.</p>
  
  <p>I have tried quitting Xcode, Restarting my Macbook and unhooking my external monitor; but haven't had luck with any of those. </p>
  
  <p>Thank you</p>
