What means or libraries have you used when implementing the WebSocket protocol in your projects?

In iOS projects, the following libraries and tools are often used for working with the WebSocket protocol:

• URLSessionWebSocketTask — a built-in iOS class from version 13 that allows creating WebSocket connections without third-party libraries.

• Starscream — a popular third-party library in Swift that provides a convenient and extensible API for WebSocket, supporting SSL, pings, and reconnections.

• SocketRocket — a library from Facebook in Objective-C, also used for WebSocket, but now less popular in Swift projects.

Example of using Starscream:

import Starscream

class WebSocketManager: WebSocketDelegate {
    var socket: WebSocket!

    init(url: URL) {
        var request = URLRequest(url: url)
        request.timeoutInterval = 5
        socket = WebSocket(request: request)
        socket.delegate = self
        socket.connect()
    }

    func websocketDidConnect(socket: WebSocketClient) {
        print("Connected")
    }

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

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

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

If the project is minimalist and iOS 13+ support is sufficient, it is better to use the built-in URLSessionWebSocketTask for simplicity and reliability.
