Updated with Swift 5 and Xcode 11.4

Controller push in present animation style

    let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let viewController = storyBoard.instantiateViewController(withIdentifier: "ViewController") as! ViewController

    let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
    transition.type = CATransitionType.moveIn
    transition.subtype = CATransitionSubtype.fromTop
    self.navigationController?.view.layer.add(transition, forKey: nil)
    self.navigationController?.pushViewController(viewController, animated: false)

PopToView Controller in Dismiss Style

            let transition:CATransition = CATransition()
        transition.duration = 0.5
        transition.timingFunction = CAMediaTimingFunction(name:CAMediaTimingFunctionName.easeInEaseOut)
        transition.type = CATransitionType.reveal
        transition.subtype = CATransitionSubtype.fromBottom
        self.navigationController?.view.layer.add(transition, forKey: kCATransition)
        self.navigationController?.popViewController(animated: false)
