Structure iOS features by separating concerns across Presentation, Domain, and Data layers. Place UI logic in Presentation, domain logic in Domain, and data access in Data to decouple business rules from SwiftUI views and enable testable boundaries.

The dependency rule requires dependencies to point strictly toward the Domain layer. This ensures Data and Presentation layers depend on Domain, not on each other, keeping use cases and repositories decoupled from UI and data access.

Place repositories and use cases in the Domain layer. This centralizes domain-driven modeling and business logic, keeping them independent of data access details and SwiftUI presentation components.

Yes, you can audit layer boundaries during code reviews by mapping components to Presentation, Domain, and Data. Use the provided checklist to verify dependencies point toward Domain and ensure proper separation of concerns.

Decouple business logic from data access by implementing explicit boundaries with Clean Architecture. Define Domain models and Use Cases independently, letting the Data layer handle data fetching while Presentation manages UI state.

Separate concerns across Presentation, Domain, and Data when you need scalable feature development and testable boundaries. This separation is crucial for clarifying code ownership and maintaining decoupled UI, business logic, and data access in SwiftUI.
