What practices and approaches to software development ensure integration with continuous integration processes?

The Model-View-Controller (MVC) architectural pattern divides an application into three main components:

• Model: Responsible for data and business logic. It manages the application's data, state, and rules.
• View: Responsible for presenting data to the user. It displays the data and sends user commands to the controller.
• Controller: Acts as an intermediary between the Model and the View. It processes user input, interacts with the model, and updates the view.

In iOS, for example, a UIViewController often plays the role of the controller, managing interactions between the model and the view.

Example:

class UserModel {
    var name: String
    init(name: String) {
        self.name = name
    }
}

class UserView {
    func displayUserName(_ name: String) {
        print("User name is: \(name)")
    }
}

class UserController {
    var model: UserModel
    var view: UserView

    init(model: UserModel, view: UserView) {
        self.model = model
        self.view = view
    }

    func updateUserName(to newName: String) {
        model.name = newName
        view.displayUserName(model.name)
    }
}

This separation simplifies maintenance and extension of the application.
