title: Xcode: Launch screens may not set custom classnames when is assign to view controller
body: <p>I'm trying to implement an animation before I load the application. I thought I can do it in the <code>LaunchScreen.storyboard</code> but when assign the viewcontroller in the LaunchScreen.storyboard to a viewcontroller class I get this error: </p>

  <p>I also tried to create a new view controller inside of my mainStoryboard but at the moment I assign the viewcontroller to a viewcontroller class I got the same error.</p>
  
  <p>My question to you guys is how can I implement an animation when the application is loading without having this error ?</p>
  
  <p>I'll really appreciate your help.</p>
