What are the differences between the Viper pattern and MVC in Swift?

The Viper pattern is a more modular architecture compared to MVC. In Viper, the responsibilities are divided into five components: View, Interactor, Presenter, Entity, and Router. This separation allows for better testability and scalability. MVC, on the other hand, combines the model, view, and controller, which can lead to tightly coupled code.

Can you explain how the Viper pattern improves testability?

Sure! In Viper, each component has a specific responsibility, which makes it easier to isolate and test them individually. For example, you can test the Interactor without needing to involve the View or Presenter, leading to more focused and effective unit tests.

Are there any downsides to using the Viper pattern?

Yes, while Viper offers modularity, it can also introduce complexity due to the number of components and the need for communication between them. This can make it harder to understand for new developers compared to the simpler MVC pattern.

Which pattern would you recommend for a small project?

For a small project, MVC might be more suitable due to its simplicity and ease of implementation. Viper is better for larger projects where scalability and maintainability are critical.
