Question 1

Clean Architecture SwiftUI vs MVVM: which is better?

Accepted Answer

Clean Architecture offers superior separation of concerns and testability, but MVVM is simpler and more common in iOS. This project includes an MVVM branch for direct comparison, highlighting trade-offs in complexity and maintainability.

Question 2

How to implement dependency injection in SwiftUI Clean Architecture?

Accepted Answer

This project uses SwiftUI's @Environment to inject AppState and Interactors, providing a native, type-safe way to manage dependencies without third-party libraries, as detailed in the Business Logic Layer section.

Question 3

Is Clean Architecture overkill for small SwiftUI apps?

Accepted Answer

Yes, for apps with trivial logic, the architectural layers can add unnecessary complexity. The README's discussion on data storage choices illustrates how simpler approaches might suffice for basic use cases.

Question 4

How do I test SwiftUI views in Clean Architecture?

Accepted Answer

The project uses the ViewInspector framework to inspect and test SwiftUI views, allowing you to verify UI logic independently of business layers, as mentioned in the Key Features.

Question 5

Can I use CoreData instead of SwiftData in this setup?

Accepted Answer

Yes, the Data Access layer is abstracted via Repositories, so you can swap SwiftData for CoreData or other solutions by implementing the repository interface, maintaining the architecture's flexibility.

Question 6

What are the performance costs of using Combine in Clean Architecture?

Accepted Answer

Combine enables reactive data flow but can add overhead in memory and complexity; for high-performance or simple apps, manual state management might be more efficient, though this project integrates it seamlessly.
