scene(_ scene: UIScene, continue userActivity: NSUserActivity)在用户单击通用链接后启动应用程序时，不会调用方法。

当用户单击通用链接后，已启动的应用程序再次打开时，它工作正常。示例代码：

func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
    guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
        let incomingURL = userActivity.webpageURL,
        let components = NSURLComponents(url: incomingURL, resolvingAgainstBaseURL: true),
        let path = components.path else {
            return
    }
    let params = components.queryItems ?? [URLQueryItem]()

    print("path = \(path)")
    print("params = \(params)")
}

我尝试使用application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration，但是当用户单击链接时它永远不会被调用：

func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
    if let scene = …

DispatchGroup使用和之间有什么区别（优点和缺点）NSRecursiveLock？

看起来他们正在做完全相同的事情。
