曖昧參考成員「下標」

Question

我使用谷歌登錄框架按照有關文件

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]) 
} 

這是給錯誤

Ambiguous reference to member 'subscript'

請求幫助谷歌登錄構架這個。

我覺得iOS 9.0和之前，您應該使用此方法。檢查此answer

func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])-> Bool { 
     return GIDSignIn.sharedInstance().handleURL(url, 
         sourceApplication:options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String, 
         annotation: [:]) 
    }
