In which cases is it recommended to use the architectural pattern Model-View-Controller (MVC)?

The Model-View-Controller (MVC) architectural pattern is recommended when you need to clearly separate the application logic into three parts:

• Model — responsible for data and business logic.
• View — responsible for displaying data to the user.
• Controller — handles user input and interacts with the Model and View.

This separation simplifies support and scaling of the application, improves testability, and allows for independent development of the interface and logic.

In iOS, MVC is often used to organize code in applications, where View is a UIView and UIViewController, Model is data, and Controller is a UIViewController that connects them.

Use MVC when the application is not too complex, and you want to quickly organize code with a clear structure.
