I prefer using self navigationItem title    Your Title Here  over self title    Your Title Here  to provide title in the navigation bar since tab bar also uses self title to alter its title  You should try the following code once   Note  calling the super view lifecycle is necessary before you do any stuffs   class ViewController  UIViewController       override func viewDidLoad             super viewDidLoad           setupNavBar            private func setupNavBar         self navigationItem title    Your Title Here

You change the title by changing the title of the view controller being displayed   viewController title    some title    Normally this is done in view did load on the view controller   override func viewDidLoad         super viewDidLoad       self title    some title      However  this only works if you have your view controller embedded in a UINavigationController  I highly recommend doing this instead of creating a navigation bar yourself  If you insist on creating a navigation bar yourself  you can change the title by doing   navigationBar topItem title    some title

and also if you will try to create Navigation Bar manually this code will help you   func setNavBarToTheView         let navBar  UINavigationBar   UINavigationBar frame  CGRect x  0  y  0  width  self view frame size width  height  64 0       self view addSubview navBar       let navItem   UINavigationItem title   Camera        let doneItem   UIBarButtonItem barButtonSystemItem  UIBarButtonSystemItem cancel  target  self  action   selector CameraViewController onClickBack        navItem leftBarButtonItem   doneItem      navBar setItems  navItem   animated  true

Normally  the best-practice is to set the title on the UIViewController   By doing this  the UINavigationItem is also set   Generally  this is better than programmatically allocating and initializing a UINavigationBar that s not linked to anything   You miss out on some of the benefits and functionality that the UINavigationBar was designed for  Here is a link to the documentation that may help you   It discusses the different properties you can set on the actual bar and on a UINavigationItem   Just keep in mind    You lose back button functionality  unless you wire it yourself  The built-in  drag from the left-hand side to swipe back  gesture is forfeited   UINavigationController s are your friends
