Can you explain the data transfer mechanism in the VIPER architecture?

In VIPER architecture, data is transmitted between components along a specific path, ensuring separation of concerns and clean architecture:

1. View sends user actions (e.g., taps) to Presenter.
2. Presenter processes logic and requests data from Interactor.
3. Interactor performs business logic and interacts with the model or services, then returns the result to Presenter.
4. Presenter formats data for display and passes it back to View.
5. Router handles navigation and can receive commands from Presenter.

Thus, data flows through the chain View → Presenter → Interactor → Presenter → View, ensuring clear separation and testability.
