title: Switch from View Controller to Tab Bar Controller in a Storyboard xCode
body: <p>I am working on an app in xCode 5.  This is a first at using the Storyboard. My app starts with a simple username/password login screen. Upon successful login, I want to programmatically switch from this login View to my Tab Bar Controller with the tab index set at 1.</p>
  
  <p>I do not have a custom class for my UITabBarController. I can build one if need be.  Can someone help get me started or point me in the right direction?</p>
