Hi,
I ask myself about its necessary if I use useCase pattern with a MVVM architecture and repositories. Initially the viewModel comunicate with the repository directly.
So if I want to add a UseCase layer, the viewModel will communicate with the useCase and the useCase with repository.
Why useCase is a class, I could get the same result with protocol?
protocol AddUseCase
protocol FetchUseCase
The only reason I see to create a UseCase class is to add a validation logic (instead of it in the ViewModel) before continuing to repository.
