在 UIKit iOS 13 更改之前，如何在 SceneDelegate 设置 rootViewController？

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?


    @available(iOS 13.0, *)
    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        guard let _ = (scene as? UIWindowScene) else { return }

    }
