Service Layer을 두고, 모델을 얻기 위해 Repository에 요청하는 방식의 구조를 채택하자.
의존 구조 방향성을 한 방향으로 가져가기

ShopViewController -> ProductViewController 디렉토리 명 변경.

현재 각 뷰 별 예상 구조
-> compositional Layout으로 인해 cell에 대한 viewModel이

Clean Architecture 에서 usecase를 적용할 것인지
아니면 Service Layer에 대한 구분만 할 것인지에 대해서도 적용이 필요함

실제 Clean Architecture에 대한 부분은 milestone 1에 해당하지 않기 때문에 일단 MVVM에 대한 패턴을 확실히 하자


class EmployeesViewModel: NSObject {
    private var employeeService: EmployeeServiceProtocol
}
