SOLVED: Project 7, I've work along with the code but duplicate view controller is not created in tabbar controller

	@gkiran39 Apr '20 I had writted code in appdelegate to add duplicate viewcontroller via code to tabcontroller, but I did not find another viewcontroller added to tabbarcontroller `func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { `if let tabBarController = window?.rootViewController as? UITabBarController { let storyboard = UIStoryboard(name: "Main", bundle: nil) let vc = storyboard.instantiateViewController(identifier: "NavController") vc.tabBarItem = UITabBarItem(tabBarSystemItem: .topRated, tag: 1) tabBarController.viewControllers?.append(vc) } return true }` 4
	@Alchemy-Lab Apr '20 There is an outdated code in the Project 7 of the book Hacking with iOS / 100 Days of Swift The Xcode 11 project template add a new SceneDelegate.swift file in the project, and the SceneDelegate class manage the iOS app’s UI life cycle. And in Xcode 11, the template remove the window member variable ( UIKit.UIWindow type ) from AppDelegate class, it add the window member variable to the SceneDelegate class. So your code must be placed in below SceneDelegate class’s function func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) Remove the "return true" part 18
