windowScene 可以设置全屏打开吗？

是的，可以使用windowScene.fullScreen属性来设置全屏打开。将该属性设置为true即可实现全屏显示。以下是一个示例代码：

class SceneDelegate: UIResponder, UIWindowSceneDelegate {
    var window: UIWindow?
    
    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        guard let windowScene = (scene as? UIWindowScene) else { return }
        
        let window = UIWindow(windowScene: windowScene)
        window.rootViewController = ViewController()
        window.frame = UIScreen.main.bounds
        windowScene.fullScreen = true // 设置为全屏
        
        self.window = window
        window.makeKeyAndVisible()
    }
}

在上述代码中，我们将windowScene.fullScreen属性设置为true来实现全屏打开
