Knowledge Sharing Using Swift:

Changing root view controller from class other than app delegate.swift

let appdelegate = UIApplication.sharedApplication().delegate as! AppDelegate
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
var homeViewController = mainStoryboard.instantiateViewControllerWithIdentifier("HomeViewController") as! HomeViewController
let nav = UINavigationController(rootViewController: homeViewController)
appdelegate.window!.rootViewController = nav

Changing rootviewcontroller With Animation can be achieve with:

UIView.transitionWithView(self.window!, duration: 0.5, options: UIViewAnimationOptions.TransitionFlipFromLeft, animations: {
      self.window?.rootViewController = anyViewController
}, completion: nil)

We can write generalise method too similar to this.

Hope this will helpful for someone.
