How do I choose between MVC, MVVM, VIPER, and Clean Architecture in Swift?

When it comes to choosing an architectural pattern for Swift development, it is important to consider the specific needs of your application, as well as the preferences of your development team. Below are brief outlines of the most common architectures: MVC, MVVM, VIPER, and Clean Architecture.

Choosing the right architecture in Swift can significantly impact the scalability, testability, and maintainability of your application. Each architecture has its strengths and weaknesses that should be evaluated based on project requirements.

 
// Example of a simple MVC structure in Swift

import UIKit

// Model
struct User {
    var name: String
}

// View
class UserView: UIView {
    var nameLabel: UILabel = UILabel()
}

// Controller
class UserController: UIViewController {
    var user: User
    var userView: UserView
    
    init(user: User) {
        self.user = user
        self.userView = UserView()
        super.init(nibName: nil, bundle: nil)
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        userView.nameLabel.text = user.name
        view.addSubview(userView)
    }
}
