Change initial view controller swift

I need to change the initial view controller based on whether voiceover is on or not. I have tried multiple ways but I always get the same error: "Value of type 'AppDelegate' has no member 'window'" This is what I have in my didFinishLaunchingWithOptions. 

    print("voiceover: \(voiceOver)") // prints if voice over is on

    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let initialViewController = storyboard.instantiateViewController(withIdentifier: "voiceoverViewController")

    self.window?.rootViewController = initialViewController
    self.window?.makeKeyAndVisible()

Value of type 'AppDelegate' has no member 'window'

You don't have to declare window variable manually

It is available in SceneDelegate file in your project

It will have pre defined method :

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions)

Example

func scene(_ scene: UIScene, willConnectTo session: UISceneSession,
 options connectionOptions: UIScene.ConnectionOptions) {

    if let windowScene = scene as? UIWindowScene {          
        self.window = UIWindow(windowScene: windowScene) 
        let initialViewController = 
            storyboard.instantiateViewController(withIdentifier: "voiceoverViewController")            
        self.window!.rootViewController = initialViewController
        self.window!.makeKeyAndVisible()
    }
}

You have to declare a window property manually:

var window: UIWindow?

UIApplicationDelegate is just a protocol, it doesn't declare any properties for you.
