title: Converted Universal App doesn't show the iPad Interface
body: <p>At the moment I'm building an iPhone App.
  Yesterday I tried to convert it to an Universal App.
  It worked, but it just shows me the tab bar, but nothing else.
  I've created some Web Views and a Table View, but the iPad Simulator didn't show anything, only the tab bar.
  The iPhone Simulator works great, I can see all the labels, web views etc...
  I've created one Storyboard for iPhone and one for iPad.</p>
  
  <p>I don't know why the iPad Simulator doesn't display anything.</p>
  
  <p>Hope you can help me.</p>
  
  <p>Regards</p>
