Describe the process of data transfer from the server side through the network to the user interface in your previous project.

In my previous iOS project, the data transfer process looked like this:

1. The server-side (e.g., REST API) generated a JSON response to the client's request.
2. An HTTP request was sent to the server from the iOS app using URLSession.
3. The received JSON document was deserialized into data models using Codable.
4. After successful parsing, the data was passed to the business logic layer.
5. Then, the user interface was updated, for example, by refreshing a UITableView or a SwiftUI View, to display the new data.

Example of a request and data processing:

struct User: Codable {
    let id: Int
    let name: String
}

func fetchUsers() {
    let url = URL(string: "https://api.example.com/users")!
    URLSession.shared.dataTask(with: url) { data, response, error in
        guard let data = data else { return }
        do {
            let users = try JSONDecoder().decode([User].self, from: data)
            DispatchQueue.main.async {
                // update UI with users
            }
        } catch {
            print("Parsing error: \(error)")
        }
    }.resume()
}
