What benefits do you get by using Viper architecture?

Using Viper helps you keep your code better organised and makes it more testable because each of its five parts (View, Interactor, Presenter, Entity, Router) has its own responsibility. This structure prevents you from ending up with messy 'massive view controllers.' You can test each part independently, so issues are easier to identify and fix. Viper also makes your code easier to reuse and more scalable, which is why it is a strong choice for larger, more complex applications that need to stay clear, maintainable, and easy to expand.
