Firebase-无法登录到Facebook身份验证

在身份验证完成并且用户登录到Facebook后，我试图移至新的视图控制器，但出现错误消息"Error Domain = FIRAuthErrorDomain Code = 17999"，发生内部错误，请打印并检查有关错误的详细信息，以获取更多信息."我看了一下文档，对我来说似乎很对，但是也许我遗漏了一些东西.这是我的Facebook登录按钮的代码

I'm trying to move to my new view controller after the auth is complete and the user has loged into facebook but I get a error saying "Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and inspect the error details for more information."" I've looked over the documentation and it looks right to me but maybe I'm missing something. Here is my code for my facebook login button

@IBAction func FacebookBtnPressed(sender: AnyObject) {
    let login = FBSDKLoginManager()

    login.logInWithReadPermissions(["email"], fromViewController: self) { (result: FBSDKLoginManagerLoginResult!, facebookError: NSError!) -> Void in

        if (facebookError != nil) {
            print("Facebook login failed. Error: \(facebookError)")
        } else if result.isCancelled {
            print("Cancelled")
        } else {
            let acessToken = FBSDKAccessToken.currentAccessToken().tokenString
            print("Logged in. \(acessToken)")

            let credential = FIRFacebookAuthProvider.credentialWithAccessToken(FBSDKAccessToken.currentAccessToken().tokenString)

            FIRAuth.auth()?.signInWithCredential(credential, completion: { (user, error) in

                if error != nil {
                    print("Login failed. \(error)")
                } else {
                    print("Logged in. \(user)")

                    let userData = ["provider": credential.provider]
                    DataService.ds.createFirebaseUser(user!.uid, user: userData)

                    NSUserDefaults.standardUserDefaults().setValue(user!.uid, forKey: KEY_UID)
                    self.performSegueWithIdentifier("loggedIn", sender: nil) // currently not working
                }

            })
