How to make navigation bar not disappear on segue?

Question

Swift

by clicking on "Register" the transition to the next page occurs with the help of segue, but for some reason the Navigation Bar is not visible. Moreover, if you comment out all the code that concerns the UIView, then it is visible.

Answer 1

Here in the next page controller write this:

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        navigationController?.setNavigationBarHidden(false, animated: false)
}
