Can't dismiss navigation controller in Swift

Question

So I have a simple navigation controller with a sign up, hit done and you go to the home page. The problem is when you go to the home page, the navigation controller follows

Answer 1

//hide the navigation bar on this page
override func viewWillAppear(_ animated: Bool) {
    self.navigationController?.isNavigationBarHidden = true
}

This will hide the navigation bar on your home page, but make sure you use viewWillAppear so whenever you come back to a page the navigation will not reappear.

Answer 2

Try to use a ViewController only for the LoginView. Then use self.dismiss with PerformSegue to reach the NavigationController.

Answer 3

Try

self.navigationController?.popViewControllerAnimated(true)

Update: Swift 4.2

self.navigationController?.popViewController(animated: true)

Answer 4

Is a signup view controller being presented Modally? Then, on sign up view controller, you could do

self.dismiss(animated: true, completion: nil)
