iOS SDK, How to tell if a user is new when using Facebook?

Hi is there a way to tell if a user is brand new or existing in the database when calling Backendless.sharedInstance().userService.loginWithFacebookSDK
like if the returned user object I can check if user.isNew
I need to use it for analytics purpose

Hi Olive,

For you purpose you could use the next code:

                permissions: permissions,
                fieldsMapping: fieldsMapping,
                response: { (user: BackendlessUser!) -> Void in
                    if user.getProperty(BACKENDLESS_USER_REGISTERED) as? NSNumber != nil {
                        print("NEW REGISTATION")
                error: { (fault: Fault!) -> Void in
                    print("Server reported an error: \(fault)")
