iOs Twitter登录（快速）获取用户身份验证令牌时出错。错误：请求失败：禁止（403）

Question

我正在尝试在应用程序中使用Twitter登录，但出现错误

FirebaseProject[9536:57007] [TwitterKit]
Error obtaining user auth token.
error: Request failed: forbidden (403)

和我的info.plist

和AppDelegate.swift

     func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
       return TWTRTwitter.sharedInstance().application(app, open: url, options: options)
    }
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        Thread.sleep(forTimeInterval:3)
        IQKeyboardManager.shared.enable = true
        FirebaseApp.configure()
        TWTRTwitter.sharedInstance().start(withConsumerKey:"4-----L", consumerSecret:"bc----------------------b")

找不到，我怎么了。
