How can I test WebSockets in SwiftUI?

You can test WebSockets in SwiftUI by using the URLSessionWebSocketTask class to create a WebSocket connection.

Can you show me a simple example of how to implement this?

Sure! Here's a basic example:

import SwiftUI

struct ContentView: View {
    @State private var message = ""
    @State private var receivedMessage = ""

    var body: some View {
        VStack {
            Text(receivedMessage)
            TextField("Type a message", text: $message)
            Button("Send") {
                sendMessage()
            }
        }
    }

    func sendMessage() {
        let url = URL(string: "wss://your-websocket-url")!
        let webSocketTask = URLSession.shared.webSocketTask(with: url)
        webSocketTask.resume()
        let messageToSend = URLSessionWebSocketTask.Message.string(message)
        webSocketTask.send(messageToSend) { error in
            if let error = error {
                print("Error sending message: \(error)")
            }
        }
        receiveMessage(webSocketTask: webSocketTask)
    }

    func receiveMessage(webSocketTask: URLSessionWebSocketTask) {
        webSocketTask.receive { result in
            switch result {
            case .failure(let error):
                print("Error receiving message: \(error)")
            case .success(let message):
                switch message {
                case .string(let text):
                    receivedMessage = text
                default:
                    break
                }
            }
        }
    }
}

What are some common issues I might face while testing?

Common issues include connection timeouts, message format errors, and handling unexpected disconnections.
