The document compares the MVVM-C and MVP architectures. It discusses problems with the traditional MVC pattern, such as the view controller being a "God" class and mixing of business logic and UI. It then introduces MVP and MVVM as solutions, outlining the responsibilities of each component in each pattern. MVVM-C builds upon MVVM by adding a coordinator to handle navigation and building of view-model stacks. The document notes similarities but also differences between MVP and MVVM, such as how bindings are handled, and concludes by listing advantages of MVP/MVVM-C such as decoupling business logic from UI and improved testability and reusability.
