This project is a simple example of VIP architecture and network foundation on iOS using:

• RxSwift for asynchronous tasks and communication between the different components
• Swinject for dependency injection
• SnapKit for UI constraint management

There are some differences with the original VIP (real abstraction of the different components, communication with Rx)

• The different components (View, Interactor and Presenter) are abstracted by the protocol ViewType, Interactor and Presenter.
• The ViewController acts like a bridge between View, Interactor and Presenter. It holds these instances. It also holds a Router instance for navigation if needed.
• View contains UI elements and exposed through the protocol ViewType:
  • a method "update" which takes in parameter a Driver<T> where T is a view model, to handle a continuous update,
  • a method "request" which returns all the event from the view formatted as an EventRequest
• Interactor handles business logic and holds Model instances. It takes in input an EventRequest, representation of a request from the View.
• Presenter handles transformation of data to ViewModel. It takes in input an EventResponse, representation of a response from the Interactor.
• Router handles navigation from an EventRequest given in input and returns an Observable<EventResponse>
• Model are abstracted with protocol and always injected in Interactor.
• Data layer follows the Repository pattern abstracted by the protocol Repository.
• About folder hierarchy:
  • Foundation contains all transversed extensions/dependencies. Also, there is all the abstraction of VIP components.
  • Scene contains ViewController/Presenter/Interactor/View/ViewModel for each feature of the app.
