VIP (View-Interactor-Presenter) is Uncle Bob's Clean Architecture applied to iOS with strict unidirectional data flow. Unlike MVVM (bidirectional) or VIPER (complex 5-component), VIP uses 3 core components with protocol-based boundaries.

Core Principle: Data flows in one direction: View → Interactor → Presenter → View. No component ever calls backward in the cycle.

| Component | Responsibility | Testability | What It Must NOT Do |

Implement VIP (View-Interactor-Presenter) Clean Architecture for iOS apps requiring maximum testability, unidirectional data flow, and protocol-based boundaries. Use when refactoring complex features or building enterprise apps with strict separation of concerns. Source: dagba/ios-mcp.
