What are the key components of the Viper architecture?

The key components of the Viper architecture are View, Interactor, Presenter, Entity, and Router. The View displays UI elements and also listens and responds to a user’s tap or other interactions. The Interactor includes business operations; for instance, data processing. The Presenter acts like an intermediary between View and Interactor, maintaining the data format according to the UI requirements and taking action on user interactions. The Entities are simple data models representing data in the application, while the Router manages and keeps track of all navigation and screen transitions. This kind of separation keeps the responsibility clear, modular, and testable; hence, Viper is especially useful in large, complex applications where maintainable and organized code is a must.
