Custom UINavigationBar from AppDelegate

I made a custom UINavigationBar and I would like to use it globally. I see in other examples that for setting UINavigationBar appearance globally, you have to do something like this let navigationBar = UINavigationBar.appearance() in the AppDelegate. Then you can set up the the properties. In my case, I have set up all the properties in class var like so:

extension UINavigationBar {
    class var customNavBar : UINavigationBar{
        let navigationBar = UINavigationBar()
        navigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Avenir-Black", size: 40)!, NSForegroundColorAttributeName: UIColor.RED]

        //gets rid of black separation bar
        navigationBar.shadowImage = UIImage()
        navigationBar.setBackgroundImage(UIImage(), for: .any, barMetrics: .default)

        //set the background color to white
        navigationBar.tintColor = UIColor.white
        navigationBar.isTranslucent = false
        return navigationBar
    }
}

Now, how can I set the UINavigationBar from AppDelegate to inherent these properties. I mean having something like this in the app delegate. Or similar of course. In AppDelegate:

let navigationBar  = UINavigationBar.customNavBar.appearance()

The reason I would like to do this is because I have some other UIViewControllers (that do not segue from my TabViewController), where I would like to manually add the a UINavigationBar and it has to look just like the custom one.

My code was wrong In swift you should use 

NavController = UINavigationController.init(navigationBarClass: yoursubClass, toolbarClass: AnyClass?)

Then 

if let window = self.window{
        window.rootViewController = NavController
 }

If you want to customise your navigation bar to that degree, you might be better off making a subclass. The catch is that you will need to manually pass the class name into any navigation controllers that need to use it. You can do the same for a UIToolbar if you need to, or pass nil to use the default.

class MyNavigationBar: UINavigationBar {
    override init(frame: CGRect) {
        super.init(frame: frame)
        // configure your nav bar here
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

let navController = UINavigationController(navigationBarClass: MyNavigationBar.self, toolbarClass: nil)
