Project 7 issue with Xcode 11.1

[weters]

The following code does not work in new project created in Xcode 11.1 due to the changes to SceneKit.

if let tabBarController = window?.rootViewController as? UITabBarController {
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewController(withIdentifier: "NavController")
    vc.tabBarItem = UITabBarItem(tabBarSystemItem: .topRated, tag: 1)
    tabBarController.viewControllers?.append(vc)
}

I was able to get it working by doing the following in a new project:

1. Delete SceneDelegate.swift
2. Delete Application Scene Manifest in Info.plist
3. In AppDelegate.swift, do the following:
   1. Add var window: UIWindow?
   2. Delete application(_ :, configurationForConnecting:, options:) and application(_:, sceneSessions:)

The other option is to add it to SceneDelegate instead
I updated the willConnectTo method from:

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        guard let _ = (scene as? UIWindowScene) else { return }
    }

to :

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        guard let _ = (scene as? UIWindowScene) else { return }
        if let tabbedBarController = window?.rootViewController as? UITabBarController {
            let storyboard = UIStoryboard(name:"Main", bundle: nil)
            let vc = storyboard.instantiateViewController(withIdentifier: "NavController")
            vc.tabBarItem = UITabBarItem(tabBarSystemItem: .topRated, tag: 1)
            tabbedBarController.viewControllers?.append(vc)
        }
    }
