How do I separate domain, data, and presentation layers in Swift?

In Swift, it's essential to architect your application using a layered approach to ensure maintainability, scalability, and testability. The application can be divided into three main layers:

1. Domain Layer: This is where the business logic resides. It defines the core interactions and models that the application will use.

2. Data Layer: This layer is responsible for data management, which includes fetching, saving, and persisting data. It abstracts the data sources like APIs, databases, and caches.

3. Presentation Layer: This layer is responsible for the user interface and user experience. It communicates with the domain layer to present data and handle user interactions.
