What are the differences between the VIPER and Clean Swift architectural patterns in mobile development?

VIPER and Clean Swift are architectural patterns for iOS, aimed at separation of concerns and improved testability, but they have some differences:

• VIPER consists of five components: View, Interactor, Presenter, Entity, and Router. Each is responsible for its part of the logic: View — UI, Interactor — business logic, Presenter — connects View and Interactor, Entity — data models, Router — navigation.

• Clean Swift (also known as VIP) is a simplified version of VIPER, where the main components are View, Interactor, and Presenter. Clean Swift emphasizes data flow and clear separation of responsibilities, but without a separate Router and Entity as in VIPER.

Main differences:

• VIPER is more modular and formal, with a separate Router for navigation.
• Clean Swift is simpler and easier to understand, suitable for projects with less complexity.

The choice between them depends on the project requirements and team preferences.
