How do I connect to my WebSocket server?

This library is NOT a WebSockets library. This library is only for servers that implement the socket.io protocol, such as socket.io. If you need a plain WebSockets client check out Starscream for Swift and JetFire for Objective-C.

Why isn’t my event handler being called?

One of the most common reasons your event might not be called is if the client is released by ARC.

Take this code for example:

class Manager {
    func addHandlers() {
        let manager = SocketManager(socketURL: URL(string: "http://somesocketioserver.com")!)

        manager.defaultSocket.on("myEvent") {data, ack in
            print(data)
        }
    }

}

This code is incorrect , and the event handler will never be called. Because as soon as this method is called manager will be released, along with the socket, and its memory reclaimed.

A correct way would be:

class Manager {
    let manager = SocketManager(socketURL: URL(string: "http://somesocketioserver.com")!)

    func addHandlers() {
        manager.defaultSocket.on("myEvent") {data, ack in
            print(data)
        }
    }
}
