What architectural structure would you use when creating this component?

The choice of architectural structure for a component in iOS depends on its complexity and requirements for support and testing.

Common architectural patterns include:

• MVC (Model-View-Controller) — a classic pattern where the View displays data, the Controller manages logic, and the Model contains data. Suitable for simple components.

• MVVM (Model-View-ViewModel) — separates presentation logic into the ViewModel, which simplifies testing and binding to UI through bindings.

• VIPER — a more modular and scalable pattern that divides responsibilities into View, Interactor, Presenter, Entity, and Router. Used in large projects.

For most medium-level components, I would recommend MVVM, as it provides good separation of responsibilities and simplifies maintenance:

• Model — business logic and data.
• View — UI components.
• ViewModel — transforms data from the model for display and handles user actions.

This allows easy testing of the ViewModel separately from the UI and maintains code cleanliness.
