Facebook 로그인 + Firebase + Xcode 8 & Swift 3. ERROR

Question

Xcode는 AppDelegate에서 작성한 모호한 참조에 대해 불평합니다. this tutorial을 사용하여 Xcode 프로젝트에서 Facebook 로그인을 Firebase와 통합하려고합니다.

오류 :

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

코드 :

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 
} 

잘 모르겠어요 무엇 무엇을 (아이폰 OS 프로그래밍 여전히 신규)이 오류 수단. 나는 코멘트가있는 코드에서 일어나는 부분을 강조했다.

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 
    }
