Why do we customize UINavigationBar's barTintColor exactly in AppDelegate?

Somebody writes this kind of code 

override func viewDidLoad() {
    super.viewDidLoad()

    // Status bar white font
    self.navigationBar.barStyle = UIBarStyle.Black
    self.navigationBar.tintColor = UIColor.whiteColor()
}

but it doesn't work, updating it in AppDelegate really works, but why it doesn't work from viewDidLoad?

You can set these properties in XIB/Storyboard. No need to set it in every controller.

If you want to set it from view controller so you need to self.navigationController?.navigationBar.barTintColor = typeyourcolor.

Navigation bar is the property of navigation controller not the view controller.

try this :

override func viewDidLoad() {
        super.viewDidLoad()

        self.navigationController?.navigationBar.barStyle = .black
        self.navigationController?.navigationBar.tintColor = UIColor.white

}
