What are the main components of a network request?

The main components of a network request in iOS include:

• URL — the address of the resource being requested.
• URLRequest — an object that contains information about the request: URL, HTTP method (GET, POST, etc.), headers, and body.
• URLSession — an object that manages the execution of network tasks.
• URLSessionTask — a task that performs the request and receives the response.
• Response — data received from the server, including status, headers, and body.

Example of a simple GET request using URLSession:

let url = URL(string: "https://api.example.com/data")!
let task = URLSession.shared.dataTask(with: url) { data, response, error in
    if let data = data {
        // process the received data
        print(String(data: data, encoding: .utf8) ?? "")
    } else if let error = error {
        print("Error: \(error.localizedDescription)")
    }
}
task.resume()
