Answer from AI
VIPER architecture divides responsibilities into five components: View, Interactor, Presenter, Entity, and Router. This provides clearer modularity and easier maintenance compared to MVC, where the ViewController often becomes too overloaded (Massive View Controller).
Advantages of VIPER over MVC:
- Clear separation of responsibilities: each component is responsible for its part of the logic.
- Better testability: business logic is isolated in the Interactor, simplifying the writing of unit tests.
- Improved scalability: easier to add new features without changing existing code.
- Explicit navigation: the Router handles transitions between screens, simplifying navigation management.
Example: in MVC, the ViewController contains both display logic and business logic, whereas in VIPER these responsibilities are divided between the Presenter and Interactor.
