How do I structure feature modules in UIKit with Swift?

Structuring feature modules in UIKit with Swift allows you to create a more organized and maintainable codebase. By following best practices, you can enhance the scalability of your iOS applications.

 // Example of structuring a feature module
import UIKit

// MARK: - UserProfile Module
class UserProfileViewController: UIViewController {
    var user: User?

    override func viewDidLoad() {
        super.viewDidLoad()
        setupView()
    }

    private func setupView() {
        // Setup your user profile view elements here
    }
}

// MARK: - User Model
struct User {
    let id: Int
    let name: String
    let email: String
}

// Module to handle user service
class UserService {
    func fetchUser(for id: Int, completion: @escaping (User?) -> Void) {
        // Simulate network request
        let user = User(id: id, name: "John Doe", email: "johndoe@example.com")
        completion(user)
    }
}
