Socket.io examples with Swift and Node.js on the backend

I am trying to find a working example of implementing Socket.io on iOS with Swift, but so far no luck. I got some examples from Github, but each one has some problems, and I cannot say why they do not work.

Does anyone know where I can get a working example from a window so that I can go through the code and understand the implementation?

Since I asked the question, there have been changes, and now I have socket.io for iOS. Here's the original blog post: http://socket.io/blog/socket-io-on-ios/

Based on socket.io examples:

Server (index.js, see socket.io site for configuration):

var app = require('express')(); var http = require('http').Server(app); var io = require('socket.io')(http); app.get('/', function(req, res){ res.sendFile(__dirname + '/index.html'); }); io.on('connection', function(socket){ socket.on('chat message', function(msg){ io.emit('chat message', msg); }); }); http.listen(8080, function(){ console.log('listening on *:8080'); });

Client (ViewController.swift):

 import UIKit import Socket_IO_Client_Swift class ViewController: UIViewController { @IBOutlet weak var chatView:UITextView! @IBOutlet weak var sendButton:UIButton! @IBOutlet weak var sendField:UITextField! let socket = SocketIOClient(socketURL: "10.0.0.1:8080", opts: ["log": true]) override func viewDidLoad() { super.viewDidLoad() addHandlers() self.socket.connect() } @IBAction func send() { self.socket.emit("chat message", withItems: [self.sendField.text!]) self.sendField.text = "" } func addHandlers() { self.socket.on("connect") {data, ack in print("socket connected") } self.socket.on("chat message") {[weak self] data, ack in if let value = data.first as? String { self?.chatView.text?.appendContentsOf(value + "\n") } } } }

Web Client (index.html, useful for testing):

 <!doctype html> <html> <head> <title>Socket.IO chat</title> <style> * { margin: 0; padding: 0; box-sizing: border-box; } body { font: 13px Helvetica, Arial; } form { background: #000; padding: 3px; position: fixed; bottom: 0; width: 100%; } form input { border: 0; padding: 10px; width: 90%; margin-right: .5%; } form button { width: 9%; background: rgb(130, 224, 255); border: none; padding: 10px; } #messages { list-style-type: none; margin: 0; padding: 0; } #messages li { padding: 5px 10px; } #messages li:nth-child(odd) { background: #eee; } </style> </head> <body> <ul id="messages"></ul> <form action=""> <input id="m" autocomplete="off" /><button>Send</button> </form> <script src="https://cdn.socket.io/socket.io-1.2.0.js"></script> <script src="http://code.jquery.com/jquery-1.11.1.js"></script> <script> var socket = io(); $('form').submit(function(){ socket.emit('chat message', $('#m').val()); $('#m').val(''); return false; }); socket.on('chat message', function(msg){ $('#messages').append($('<li>').text(msg)); }); </script> </body> </html>
