title: Xcode 7.1 - Prototype cells in storyboard not showing up
body: <p>I just updated to Xcode 7.1 and I noticed that all of the prototype cells in my storyboard tableviews are showing as blank and their elements are missing. Sometimes I can see the prototype cells at the top of the tableview, but when I scroll down to view the others all the cells appear blank and white again.</p>
  
  <p>Has anybody else experienced this and is there a quick fix? </p>
