node.js - 无法在 Swift 中使用 Socket.IO 客户端从服务器读取响应

问题描述

我正在尝试从 iOS 客户端连接到我的 Socket.io 服务器（Node/Express）。这是服务器（JS）的代码：

// Server Code
io.on('connection', (socket) => {

    console.log('user connected');


})

这是我的客户端代码（Swift）：

override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        
        // Testing Socket.io
        let manager = SocketManager(socketURL: URL(string: "http://<my ip address>:3001")!, config: [.log(true), .compress])
        let socket = manager.defaultSocket
        
        socket.on("connection") {data, ack in
            print("EG socket connected")
        }
        
        socket.connect()
    }

我期待 Swift 控制台打印“EG socket connected”。相反，这是我收到的：

我错过了一步吗？
