iOS项目移除SceneDelegate

直接删除 SceneDelegate.swift 文件

在AppDelegate.swift添加 window 属性，并初始化

class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow! = UIWindow(frame: UIScreen.main.bounds)

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    
        window.makeKeyAndVisible()
        window.rootViewController = ViewController()
        return true

    }
}

移除AppDelegate.swift 里面UISceneSession Lifecycle 的代理方法

// **MARK: UISceneSession Lifecycle**

    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {

        // Called when a new scene session is being created.
        // Use this method to select a configuration to create the new scene with.
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    }

    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {

        // Called when the user discards a scene session.
        // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
        // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
    }
