Answer 1

Your navigation bar might be hidden, try adding this code in viewcontroller which get called by the segue

override func viewWillAppear(_ animated: Bool) {
    self.navigationController?.setNavigationBarHidden(false, animated: true)
}

Note: Please check the viewController pushing the segue with "myView" is embeded in UINavigationController .
