Inside a UIViewController

transition = CATransition.animation
transition.timingFunction = CAMediaTimingFunction.functionWithName( KCAMediaTimingFunctionEaseIn)
transition.duration = 0.25
transition.type = KCATransitionMoveIn #Push Reveal
transition.subtype = KCATransitionFromRight
self.navigationController.view.layer.removeAllAnimations
self.navigationController.view.layer.addAnimation(transition, forKey:KCATransition)
 vc=UIViewController.alloc.init
 self.navigationController.pushViewController(vc, animated:false)
