socket.on callback repeat multiple times in socket.io swift - swift

Question

I'm using pod 'Socket.IO-Client-Swift', '~> 14.0.0'
here is my socket manager file
I don't know why socketGetLatestMsg() callback repeat multiple times when I send message once this call one but after second message callback repeat twice after 3 msg callback repeat thrice and so on...
and go back to user lists inbox and come back to same user all repeated message show as it is but in database repeated message not save.
class SocketIOManager: NSObject {
static let shared = SocketIOManager(chatID: nil, token: nil);
var socket: SocketIOClient?
var manager: SocketManager?
init(chatID: Int?, token: String?) {
super.init();
if chatID != nil && token != nil {
manager = SocketManager(socketURL: URL(string: SOCKET_URL)!, config: [.log(true), .compress, .connectParams(["auth_token": token!, "user_id": chatID!])])
self.socket = manager!.defaultSocket;
} else if UserDefaults.standard.value(forKey: "userID") != nil && UserDefaults.standard.value(forKey: "authToken") != nil {
manager = SocketManager(socketURL: URL(string: SOCKET_URL)!, config: [.log(true), .compress, .connectParams(["auth_token": UserDefaults.standard.value(forKey: "authToken") as! String, "user_id": UserDefaults.standard.value(forKey: "userID") as! Int])])
self.socket = manager!.defaultSocket;
}
self.socket?.connect();
}
