What specific WebSocket protocol implementation have you used in your projects?

In iOS projects, the Starscream library is often used to implement the WebSocket protocol — a popular and easy-to-use solution.

Example of using Starscream:

import Starscream

class WebSocketManager: WebSocketDelegate {
    var socket: WebSocket!

    init() {
        var request = URLRequest(url: URL(string: "wss://example.com/socket")!)
        socket = WebSocket(request: request)
        socket.delegate = self
        socket.connect()
    }

    func websocketDidConnect(socket: WebSocketClient) {
        print("Connection established")
    }

    func websocketDidDisconnect(socket: WebSocketClient, error: Error?) {
        print("Disconnection: \(error?.localizedDescription ?? "no error")")
    }

    func websocketDidReceiveMessage(socket: WebSocketClient, text: String) {
        print("Received message: \(text)")
    }

    func websocketDidReceiveData(socket: WebSocketClient, data: Data) {
        print("Received data: \(data.count) bytes")
    }
}

Starscream supports all main WebSocket functions, including connection, sending and receiving messages, error handling, and reconnection.
