UIViewController in iOS app launch screen

Is it possible to add a view controller to launch screen in iOS ? if yes How could i do that ?

I have dragged a UIViewController to the LaunchScreen.xib file its run correctly, but when i changed the class for the view controller in the LaunchScreen.xib from "identity inspector" from UIViewController to myLaunchScreenViewControllerName i faced this error

Illegal Configuration : Launch screen may not use instance of myLaunchScreenViewControllerName

if you can help me I will be thankful for you thanking in advance :)
