Sort of "Clean Architecture"

3 main layers: Presentation, Domain, and Data

It’s the layer that interacts with the UI. Very platform dependent.

It manage the state of the UI.

Examples of classes:

• iOS: ViewController, View, any UIControl, ViewModel
• Android: Activity, Fragment, Presenter, ViewModel

Pattern: MVVM, MVP or MVC?

Also known as business logic. This layer has the rules of our business.

It might manage some state, even persist it.

Examples of classes:

• data models
• managers
• repository

In this layer, you have definitions of the different data sources.

It basically encapsulates the interaction with the underlying platform (iOS or Android) or services/libraries (networking library, database, Firebase, etc), so that the rest of the code can be agnostic and reusable.

Examples of classes:

• HTTP client
• database
