The Model-View-ViewModel (MVVM) architectural pattern is a design approach that separates an application's user interface logic from its business logic. In iOS development:
Model: Represents data and business logic, independent of the UI.
View: Displays information and captures user input. In iOS, this is typically a UIView or UIViewController.
ViewModel: Acts as an intermediary between Model and View, containing the presentation logic and state. It exposes data and commands for the View to bind to.
MVVM promotes a clear separation of concerns, enhances testability, and facilitates data binding. The ViewModel transforms Model information for View consumption and handles View-related logic, making the View as passive as possible.
