How to connect Socket in Swift 4

Question

I want to connect my app to the socket here is the code :-

  import UIKit
  import SocketIO

 class SocketIOManager: NSObject {
static let manager = SocketManage         


        

Answer 1

You should make a shared property in your SocketIOManager class like this:

static let shared = SocketIOManager()

and then create init() like this:

    var socket: SocketIOClient!

    // defaultNamespaceSocket and swiftSocket both share a single connection to the server
    let manager = SocketManager(socketURL: URL(string: "http://localhost:3000")!, config: [.log(true), .compress])

    override init() {
        super.init()

        socket = manager.defaultSocket
        }

and finally write your methods like this:

func connectSocket() {
    let token = UserDefaults.standard.getAccessToken()

    self.manager.config = SocketIOClientConfiguration(
        arrayLiteral: .connectParams(["token": token]), .secure(true)
        )
        socket.connect()
}

func receiveMsg() {
    socket.on("new message here") { (dataArray, ack) in

        print(dataArray.count)

    }
}

and call your method like this:

SocketIOManager.shared.connectSocket()

The point is that you should make a strong reference to manager property in your viewController and static let shared = SocketIOManager() you do this for you!
