无法在Swift中通过Socket.io建立连接

我正在使用socket.io框架来编写Swift代码。我试图通过Websockets API进行连接，我有一个方法，在ViewController的viewDidLoad中调用。我已经全局声明了我的管理器和socketClient，下面是该方法的代码：

private func setupSockets() {
    manager = SocketManager(socketURL: URL(string: "http://kaboom.rksv.net")!, config: [.log(true), .compress])
    socket = SocketIOClient(manager: manager, nsp: "/watch")//manager.defaultSocket
    socket.onAny {print("Got event: \($0.event), with items: \($0.items)")}

        socket.on("data", callback: { (data, ack) in
        print(data)
    })

    socket.on("error", callback: { (data, ack) in
        print(data)
        print(ack)

    })


    socket.on("connect", callback: { (data, ack) in
        print(data)
        print(ack)


        self.socket.emit("ping", [])

    })

    socket.connect()
}

我遇到的问题是connect回调函数没有被调用，因此我无法发送ping消息。以下是日志:

我有什么遗漏的吗？做错了什么吗？提前感谢。

你是如何解决它的？ - Abhishek

声明应该像这样，你忘记设置端口了。

   let manager = SocketManager(socketURL: URL(string: "http://localhost:8080")!, config: [.log(true), .compress])
   let socket = manager.defaultSocket
我并没有在本地运行它，这是一个第三方服务器。 - shravan.sukumar

使用以下的命名空间：

let socket = socketManager.socket(forNamespace: "/watch")
