我在亚马逊上托管Ejabberd聊天服务器并在那里添加了两个用户，当我尝试通过 Ejabberd 服务器连接时Adium，它要求证书然后才连接，现在我正在Swift使用 Ejabberd 服务器和 XMPP 开发聊天应用程序，我配置了所有代码，通过主机名和端口号：5222，但它没有连接到服务器。我是否需要编写程序来获取服务器证书并将我的计算机证书（.p12）文件传递给服务器？
注意：我在 localhost 和 iOS Swift 代码中配置了 Ejabberd 服务器，当我从 iOS 应用程序发送消息然后它显示在 Adium 中时，它运行良好，当 Adium 用户发送消息时，我转到 Ejabberd Web 管理面板并可以检查离线消息。
以下是用于连接 Amazon 上托管的 Ejabberd 的 Swift 代码：
