title: How do I create a view controller file after creating a new view controller?
body: <p>I am developing a tabbed application.</p>
  
  <p>When I create a new view controller and link it to the tab bar controller, unlike the other two default view controllers, this one has no <code>viewcontroller.swift</code> file.</p>
  
  <p>How can I create this file?</p>
  
  <p>I am using Xcode 6 and developing the app in Swift.</p>
