Connect to server success but cannot connect to channel or listen event to get data.

[sonhd92]

This is the first time I'm working with SocketIO and have socket info like this:

Link socket: https://dev-cpl-backend-echo-auth-v2.staging-bitcastle.work;
Channel: App.Orders_USDT_BTC
Event: App\\Events\\OrderTransactionCreated

I wrote a wrapper class for handling socket connections, which connected to a socket successfully but cannot listen to an event.:

import SocketIO

class CPLSocketManager: NSObject {
static let sharedSocket = CPLSocketManager()

var socket: SocketIOClient!
private let manager = SocketManager(socketURL: URL(string: "https://dev-cpl-backend-echo-auth-v2.staging-bitcastle.work/")!, config: [.log(true), .compress])

private override init() {
    super.init()
    socket = manager.defaultSocket
}

func startSocket() {
    socket.on(clientEvent: .connect) { data, ack in
        print(data)
        print("-----SOCKET CONNECTED-----")
    }

    socket.on(clientEvent: .error) { data, ack in
        print(data)
        print("-----SOCKET ERROR-----")
    }

    socket.on(clientEvent: .disconnect) { data, ack in
        print(data)
        print("-----SOCKET DISONNECT-----")
    }

    socket.on(clientEvent: .reconnect) { data, ack in
        print(data)
        print("-----SOCKET RECONNECT-----")
    }

    socket.connect()
}

func stopSocket() {
    socket.disconnect()
}

func connectToChannel(channelName: String, eventName: String) {
    let dict = ["channel": channelName]
    socket.emit(eventName, with: [dict])
    socket.on(channelName) { data, ack in
        print(">>channel>>>\(data)>>>>>>>>>")
    }
}

func listen(eventName: String) {
    socket.on(eventName) { data, ack in
        print("==event==\(data)>>>>>>>>>>>")
    }
}
}

In my viewcontroller I set the channel name and event name:

CPLSocketManager.sharedSocket.connectToChannel(channelName: "App.Orders_USDT_BTC", eventName: "App\\Events\\OrderTransactionCreated")
    CPLSocketManager.sharedSocket.listen(eventName: "App\\Events\\OrderTransactionCreated")

But when build and run the project then goes to my screen. The socket log shows:

So, what's wrong with my code?

[GustavoAlvarez]

@sonhd92 Did you solve it?

[WZoptal]

which ios version that you were using and also which is the server side version with server side language

[Nikunjkumar-R]

Was anyone able to solve this?
