Push Up View Controller from Bottom using Swift

Question

I would like to push a view controller using Swift and animate it so it appears from the bottom and moves up. I have the following code to push my view controller:

Answer 1

Swift3:

for push :

    // push view controller but animate modally
    let storyBoard: UIStoryboard = UIStoryboard(name: "myStoryBoard", bundle: nil)
    let vc = storyBoard.instantiateViewController(withIdentifier: "myViewControllerIdentifier") as! MyViewController

    let navigationController = self.navigationController


    vc.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Close", style: .plain, target: vc, action: #selector(vc.closeView))
    vc.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: vc, action: nil)

    let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionMoveIn
    transition.subtype = kCATransitionFromTop
    navigationController?.view.layer.add(transition, forKey: nil)
    navigationController?.pushViewController(vc, animated: false)

and in vc for pop:

func closeView() {
    let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionReveal
    transition.subtype = kCATransitionFromBottom
    navigationController?.view.layer.add(transition, forKey: nil)
    _ = navigationController?.popViewController(animated: false)
}
