Swift: How do I get access to the navigationController in AppDelegate

Question

I have added a NavigationController in the StoryBoard and made it the initial viewController. How do I get access to the NavigationController in the appDelegate. Ctrl-drag from navigationController to AppDelegate does not create an outlet.

If it's your initial view controller you can access it through `self.window.rootViewController` — spassas, Jul 31 '14 at 08:14

In didFinishLaunchingWithOptions:

let navigationController = application.windows[0].rootViewController as! UINavigationController

Getting this SIGBART error : Could not cast value of type 'SwiftControlsTest.ViewController' (0x1006303f0) to 'UINavigationController' (0x101ecb670). – Jayprakash Dubey Oct 14 '15 at 06:42
That's because you don't have a navigation controller set as the root view controller of your application. Your root view controller is a `SwiftControlsTest.ViewController` – Danny Bravo Apr 20 '20 at 06:35

In custom functions use like this:

let navigationController = self.window?.rootViewController as! UINavigationController
