How does Viper compare to MVVM for iOS projects?
The question is about VIPER
Viper and MVVM differ in structure, complexity, and suitability for various iOS projects. MVVM is organized into the usual three components: Model, which corresponds to the data; View, the UI; and ViewModel, the business logic. It’s less heavy than Viper and creates a sweet balance between code organization and development speed; thus, it’s suitable for medium projects or applications when you want to implement modular but lightweight architecture. MVVM further enhances testability and keeps view controllers lean by maintaining clarity without excessive overhead.
Viper is a more complex architecture, with its five layers: View, Interactor, Presenter, Entity, and Router, which provide much tighter separation of concerns. It allows better modularity, greater scalability, and testability-mostly when big or complex applications are touched upon, where maintainability is a concern. Viper introduces development overhead and normally fits best for enterprise-level projects only, where extensive organization and clearly defined responsibilities are needed.
To sum it up, MVVM works well on projects where improvement in organization and lightweight structure is required. The Viper architecture would be appropriate for large and complex applications since it can offer more robust, highly organized architecture.
