title: UITabBarController is empty when running the application
body: <p>I'm trying to build an application that has a uiviewcontroller with 3 viewcontrollers attached. I've got the storyboard hooks in place for the 3 view controllers. When this tab bar controller loads up, the ViewControllers array is empty and no tabs actually load up.</p>
  
  <p>I've been able to rearrange some of the tabs in storyboard, which results in 2 out of the 3 tabs showing up, sometimes it's only 1. </p>
  
  <p>It's driving me a little nuts. Does anybody have any ideas? Thanks!</p>
