$ grep -r Tag: «socket.io»

A small cheat sheet: there is a Swift client for socket.io. At first glance, GitHub documents how to use it pretty well. The problem is that it absolutely did not want to connect to my Node.js backend with the sample code.

The logs showed (when trying polling requests) that the client was hitting /engine.io and getting a 404 error. Studying the browser JavaScript library, which works with the same backend without any dancing with a tambourine, showed that a different path had to be specified: /socket.io. Fortunately, there is a dedicated option for that.

So in the end, this is what we get:

let socketURL = NSURL(string: "http://localhost:3000")
let socket = SocketIOClient(socketURL: socketURL!, options: [
    .ForceWebsockets(true),
    .Path("/socket.io/"),
    .ConnectParams(["token": "token"])
])

socket.on("connect") {data, ack in
    print("socket connected")
}

socket.connect()
