title: Xcode 10, where are the UI elements?
body: <p>Have been out of Swift coding for almost a year, I'm back. </p>
  
  <p>Download Xcode 10 beta. Have I lost my mind?  I've tried every trick I know, none of the UI elements show up in storyboard. Zero. The sidebar is empty. </p>
  
  <p>Xcode 10:</p>

  <p>Xcode 9, no problem there they are, all my UI buttons, etc.</p>
  
  <p>thanks, this is kind of surreal. :-)</p>
