*** 由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“-[FaveoHelpdeskPro_Swift.AppDelegate 窗口]：无法识别的选择器发送到实例 0x282efc980”

var window: UIWindow?

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
    // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
    // This delegate does not imply the connecting scene or …
