  • so you would like to move back from C to A directly? – PPL May 09 '18 at 12:47

  • @KristopherJohnson I guess its not navigation stack he is presenting instead of pushing. – TheTiger May 09 '18 at 12:51

    @user9294044 By presenting its not possible but if you use `navigationController` then it has `viewControllers` property which is an array and you can `remove/replace/add` any `controller` to it. Even you can use custom `presenting/dismissing` animation while `pushing` and `popping`. – TheTiger May 09 '18 at 12:54

From your eg., In D Screen you need to check self.navigationController?.viewControllers and remove desired ViewController.

    var newArray = [UIViewController]()

    if let viewControllers = self.navigationController?.viewControllers {
        for vc in viewControllers {

            if !(vc is <#Desired ViewController#>) {
                newArray.append(vc)
            }
        }
       self.navigationController?.viewControllers = newArray
    }
