Integrate WebSocket iOS

Today we will learn how to integrate web socket for live data updation in our iOS applications such as live chat etc .
Starscream is a powerful and simplest web socket which also has been used as parent library such as Stompclient use Starscream as parent library.

Step 1. Install  pod 'Starscream', '~> 2.0.3' in the project in which you have required web socket.

Step 2 . After Installing web Socket in the project import Starscream in AppDelegate of your project.

import Starscream

Step 3. Add WebSocketDelegate  in AppDelegate Class.

class AppDelegate: UIResponder, UIApplicationDelegate,WebSocketDelegate {

Step 4. Now Add all required Delegates in your class as follows

   
    // MARK: Websocket Delegate Methods.
    
    func websocketDidConnect(socket: WebSocket) {
        print("websocket is connected")
    }
    func websocketDidDisconnect(socket: WebSocket, error: NSError?) {
        if let e = error {
            print("websocket is disconnected: \(e.localizedDescription)")
        } else {
            print("websocket disconnected")
        }
    }
    
    func websocketDidReceiveMessage(socket: WebSocket, text: String) {
        print("Received text: \(text)")
    }
    
    func websocketDidReceiveData(socket: WebSocket, data: Data) {
        print("Received data: \(data.count)")
    }
    
    func pushSocket(){
        if socket.isConnected{
            socket.write(string: "Any Message You Want to Send")
        }
        else{
            socket.connect()
            socket.onConnect = {
                self.socket.write(string: "Any Message You Want to Send")
            }
            }
        }

Step 5. Now Create an Shared Instance of your app Utility Class as follows

let appDelegateSharedInstance = UIApplication.shared.delegate as! AppDelegate

Step 6. Now send the message to web Socket as Follows

                appDelegateSharedInstance.pushSocket()

Step 7. Your message will be sent to socket server, if any message dispatched from server then it will be recieved in the delegate 

websocketDidReceiveMessage

Step 8. Your can use this socket for live updation of data or live chat or such live tasks.
