How to hide a navigation bar from first ViewController in Swift?

If you know that all other views should have the bar visible, you could use viewWillDisappear to set it to visible again.

In Swift:

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

Swift 3

override func viewWillAppear(_ animated: Bool) {    super.viewWillAppear(animated)    // Hide the navigation bar on the this view controller    self.navigationController?.setNavigationBarHidden(true, animated: animated)}override func viewWillDisappear(_ animated: Bool) {    super.viewWillDisappear(animated)    // Show the navigation bar on other view controllers    self.navigationController?.setNavigationBarHidden(false, animated: animated)}

You can unhide navigationController in viewWillDisappear

override func viewWillDisappear(animated: Bool){    super.viewWillDisappear(animated)    self.navigationController?.isNavigationBarHidden = false}

Swift 3

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