Facebookログイン+ Firebase + Xcode 8＆Swift 3. ERROR

Question

XcodeはAppDelegateで行ったあいまいな参照について不平を言っています。私はthis tutorialを使ってXcodeプロジェクトのFirebaseとFacebookログインを統合しようとしています。

エラー：

Ambiguous reference to member 'application(_:didFinishLaunchingWithOptions:)'

コード：

import UIKit 
import CoreData 
import Firebase 
import FBSDKLoginKit 


@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

    var window: UIWindow? 

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
     // Override point for customization after application launch. 
     FIRApp.configure() 
     FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 

     return true 
    } 

private func application(_ app: UIApplication, open url: URL, options: UIApplicationOpenURLOptionsKey) -> Bool { 
    var handled = FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey], annotation: options[UIApplicationOpenURLOptionsAnnotationKey]) // Error happens here 
    // Add any custom logic here. 
    return handled 
} 

私が何をどのようにこのエラーが手段（まだ新しいiOSのプログラミングに）わかりません。私は、コード内のどこにコメントがあるのか​​を強調しました。

import UIKit 
import Firebase 
import CoreData 
import FBSDKCoreKit 
import FBSDKLoginKit 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

    var window: UIWindow? 


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

     FIRApp.configure() 
     FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 
     return true 
    } 

    func application(_ application: UIApplication, open url: URL, _: NSURL, sourceApplication: String, annotation: AnyObject) -> Bool { 

     let handled: Bool = FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation) 
     return handled 
    }
