Не удалось войти на Facebook в iOS swift 4

Question

Я реализовал вход на Facebook в приложение iOS, но получаю эту ошибку:

Я нашел здесь пару решений:

1) используйте кнопку facebook по умолчанию.

2) предоставил контактный адрес электронной почты в консоли разработчика.

3) сделал приложение живым в консоли разработчика.

В режиме разработки он работает нормально, но эта проблема начинает возникать после того, как я опубликовал приложение в магазине приложений.

Я не знаю, что могло быть причиной этого. Может кто-нибудь мне помочь?

Для создания кнопки: -

if FBSDKAccessToken.current() != nil
        {
            let manager = FBSDKLoginManager()
            manager.logOut()
        }

let loginButton = FBSDKLoginButton()
    // Optional: Place the button in the center of your view.
    loginButton.delegate = self
    loginButton.frame = CGRect(x: (self.view.frame.size.width / 2) - (loginButton.frame.size.width / 2), y: self.view_facebook.frame.origin.y, width: loginButton.frame.size.width, height: loginButton.frame.size.height + 12)
    loginButton.readPermissions = ["public_profile", "email"]
    self.view.addSubview(loginButton)

Реализовали ли вы метод в AppDelegate, касающийся схемы URL?

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {

        if let appId = FBSDKSettings.appID() { 
            if url.scheme != nil && url.scheme!.hasPrefix("fb\(appId)") && url.host ==  "authorize" {
                //return FBSDKApplicationDelegate.shared.application(app, open: url, options: options)
                return FBSDKApplicationDelegate.sharedInstance()?.application(app, open: url, options: options) ?? false
            }
        }
        return false
    }
