**问题是当我用同样的客户端程序连接服务端的socket.io 版本是2.3.1 是 一切都没有问题。 但是当服务端的socket.io版本是4.4.1时就，客户端报如下错误，好像是握手失败。

The problem is when I use the same client program to connect to the server of socket.io version is 2.3.1, so everything is OK. But when upgrade socket.io version to 4.4.1 , the client will report the following error, as if the handshake failed.** " 2022-03-02 22:23:05.032546+0800 testSocketio[14588:429977] LOG SocketEngine: Starting engine.

我的核心代码 My core code:

class ViewController: UIViewController {

var manager : SocketManager?
var socket : SocketIOClient?

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    print("in testSocket")
   
   // manager = SocketManager(socketURL: URL(string:"http://myip:8051/")!, config: [.log(true),.forceWebsockets(true),.connectParams(["me" : "teacherLee","talkto":"zsj","token":"123"])])
    //socket = manager!.defaultSocket
    manager = SocketManager(socketURL: URL(string:"http://myip:8051/")!,config: [.log(true)])
    socket = manager!.socket(forNamespace: "/chat")
    
    socket!.on(clientEvent: .connect) {data, ack in
        print("socket connected")
    }

    socket!.connect()
    print("end testSocket")
}

别用这个 socket.io-client-swift 了，作者不用心，也不维护了。 Socket.io 作为 server 不错，但在 iOS 上并没有稳定可靠的 client SDK.

有什么其他的库推荐么.
