title: Xcode 4.2 iOS Empty Application and storyboards
body: <p>I'm an Xcode newbie, and I'm trying to make my first training app. Since apparently Empty Application template is the only template that offers pre-integrated Core Data, I choose that. However, after that, I can't get UI to work (it remains empty).</p>
  
  <p>What I did:</p>
  
  <ul>
  <li>Empty Application template</li>
  <li>New iPad Storyboard file</li>
  <li>Splashed Tab Bar Controller onto it</li>
  <li>Changed Main Storyboard in Project's Summary view</li>
  <li>Hit <kbd>⌘R</kbd></li>
  <li>Stared at pure-white iPad screen, without any tabs</li>
  </ul>
  
  <p>I tried diffing against another project that I created as a Tab Bar Application (which does reflect my Storyboard changes), without any insight.</p>
