title: rootViewController set in Storyboard not showing on App Launch
body: <p>I started with an Empty Application and added the storyboard file myself, added a View Controller to the storyboard and then embedded it into the Navigation Controller.  Now, when I launch the app in iOS Simulator - nothing shows.  Screenshot of my storyboard is below.  </p>
  
  <p>What needs to happen to get the "AddPerson" to show on launch?</p>

  <p>Update: Yes, Main Storyboard is set, but the Main Interface is blank.  Should that Main Interface be set to something(the drop down is blank)?</p>
