give me basic setup of URLSessionWebSocketTask, to maintain a socket connection, allow for disonnection, and suport reconnecting as best practice by this framework

To set up a URLSessionWebSocketTask for maintaining a WebSocket connection, allowing for disconnection, and supporting reconnection as a best practice, you can follow these general steps:

1. Create a URLSession and WebSocket Task:

   • Initialize a URLSession and create a URLSessionWebSocketTask with the desired URL.

2. Connect and Listen for Messages:

   • Start the WebSocket task and set up a loop to continuously receive messages. Use the receive method to handle incoming messages asynchronously.

3. Send Messages:

   • Use the send method to transmit messages over the WebSocket connection.

4. Handle Disconnection:

   • Implement a mechanism to handle disconnections gracefully. This can include listening for errors or close events and cleaning up resources.

5. Reconnect Logic:

   • Implement a reconnection strategy. This could involve attempting to reconnect after a delay when a disconnection is detected. Consider using exponential backoff to manage reconnection attempts.

6. Concurrency and Thread Safety:

   • Ensure that your WebSocket handling code is thread-safe. Use Swift's concurrency features, such as async/await, to manage asynchronous operations effectively.

For more detailed guidance on concurrency in Swift, you might find the session A Swift Tour: Explore Swift’s features and design helpful, as it covers concurrency concepts like tasks and async/await.
