What is the difference between Viper and Clean Architecture?

Viper and Clean Architecture differ mainly in their structure and flexibility. Viper is a specific way to apply Clean Architecture to iOS apps, using View, Interactor, Presenter, Entity, and Router components. Viper strictly separates these components, so the project is well organised but can feel rigid and inflexible. Clean Architecture is a more general pattern, using broad layers such as Presentation, Domain, and Data, rather than specific roles. It can be more easily applied across many different platforms, and developers can adapt the structure to meet project needs. Viper works mainly for iOS and is more structured, while Clean Architecture offers more options for different project types and sizes.
