# VIPER

  - [[VIEW]]
    - The View is the user interface. 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.
