TwitterKit登录总是首先失败，然后再尝试(Swift，TwitterKit，Firebase)

Question

我使用TwitterKit和Firebase来允许用户使用Twitter登录。当我第一次尝试使用Twitter登录时，它出现了错误：

TwitterCore无法验证会话凭据。2018-07-11 13:57:20.999365-0400 social_notes6794:1892888确实遇到了错误，消息是“未能保存会话”：error Domain=NSURLErrorDomain Code=-1005“网络连接丢失了”。UserInfo={NSUnderlyingError=0x1c044dcb0 {错误Domain=kCFErrorDomainCFNetwork代码=-1005 "(null)“UserInfo={_kCFStreamErrorCodeKey=57，_kCFStreamErrorDomainKey=1 }、NSErrorFailingURLStringKey=credentials.json、NSErrorFailingURLKey=credentials.json、_kCFStreamErrorDomainKey=1、_kCFStreamErrorCodeKey=57、NSLocalizedDescription=The网络连接丢失。} 2018-07-11 13:57:21.413753-0400 social_notes6794:1892888确实遇到了”错误获取用户令牌“消息。：error Domain=TWTRLogInErrorDomain Code=-1”未批准此客户端应用程序的回调URL。可在应用程序设置中调整已批准的回调URL“UserInfo={NSLocalizedDescription=Callback URL未批准此客户端应用程序。可在应用程序设置中调整已批准的回调URL} Twitter登录错误:请求失败:禁止(403)

但是如果我第二次尝试用Twitter登录，它就可以正常工作了。

应用程序代表

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

        window = UIWindow(frame: UIScreen.main.bounds)
        window?.makeKeyAndVisible()

        window?.rootViewController = UINavigationController(rootViewController: ViewController())

        FirebaseApp.configure()

        Twitter.sharedInstance().start(withConsumerKey:"XXX", consumerSecret:"XXX")

        return true
    }

    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
        return Twitter.sharedInstance().application(app, open: url, options: options)
    }

Twitter登录按钮代码

 let twitterLoginBtn = TWTRLogInButton { (session, err) in
            if let err = err {
                print("Twitter Login Error: \(String.init(describing: err.localizedDescription))")
                return
            }
            guard let token = session?.authToken else { return }
            guard let secret = session?.authTokenSecret else { return }
            let credential = TwitterAuthProvider.credential(withToken: token, secret: secret)

            Auth.auth().signIn(with: credential, completion: { (user, err) in

etc etc....

这显然是一个TwitterKit问题。我就是这样解决的：

    let store = TWTRTwitter.sharedInstance().sessionStore
    store.reload()
    for case let session as TWTRSession in store.existingUserSessions() {
        store.logOutUserID(session.userID)
    }
