在iOS Swift应用中使用Twilio对话API。从我们的服务器获取token，使用此token初始化TwilioConversationsClient，

func loginWithAccessToken(_ token: String) {
        // Set up Twilio Conversations client
        TwilioConversationsClient.conversationsClient(withToken: token,
                                                      properties: nil,
                                                      delegate: self) { (result, client) in
            self.client = client
        }
    }

期望客户端与Twilio同步。相反，我收到错误消息。

关于我可能做错了什么的想法？是否有一些额外的步骤来启用客户端或启用应用程序与该URL进行通信？
谢谢
