It's responsible for displaying things as directed by presenter and sends the actions taken by the user to the presenter - [[Interactor]] - The Interactor is responsible for interacting between the presenter(business logic layer) and the data(domain layer) - [[Presenter]] - This is our Business logic layer. Directing data between UI layer and Interactor Layer and taking user actions and calling to the router to move the user between views. - [[Entity]] - It's the information and data used on the functionality. In our case, it will be CoreData since our information will be stored there. - [[Router]] - It stores the navigation logic used for describing which screens need to be displayed. {{ https://miro.medium.com/max/1400/1*mmNexF2eDsOCcsmrPQYEaQ.png }}
