Google登录IOS Swift 4 AppDelegate错误

Question

我正在尝试实现Google登录以及可使用的Linkedin和Facebook登录。

我尝试按照文档进行集成。 我用cocoapods安装了Pod，编辑了info.plist，现在我正在添加AppDelegate方法。

以下代码段给了我这个错误：

无法使用索引类型为“ UIApplicationOpenURLOptionsKey”的下标“ [String：AnyObject]”的值

码：

func application(application: UIApplication,
                 openURL url: NSURL, options: [String: AnyObject]) -> Bool {

    return GIDSignIn.sharedInstance().handleURL(url as URL!,
                                                sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String,
                                                annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
}

首先，编译器似乎无法识别“ UIApplicationOpenURLOptionsSourceApplicationKey”是什么，这可能是解决方案的一个提示。

文档恰好显示了这一点，所以我很坚持。 不确定如何使此委托方法起作用。

这是我完整的AppDelegate代码：

        } else {
            print(user)
            // Perform any operations on signed in user here.

您需要使用此签名实现这两种方法

func application(_ app: UIApplication,
                 open url: URL,
                 options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool
  {
     if #available(iOS 9.0, *) {

           return GIDSignIn.sharedInstance().handle(url,sourceApplication:options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String,  annotation: [:])

     }

   return true

}

public func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {

    return  GIDSignIn.sharedInstance().handle(url,sourceApplication: sourceApplication, annotation: annotation)

}
