MVVM Architecture in iOS Apps

Understand how the Model-View-ViewModel pattern brings structure, testability, and maintainability to iOS projects. This video walks through separating business logic from UI code by introducing ViewModels that expose published state for both UIKit and SwiftUI layers to observe. You'll refactor a tightly coupled view controller step-by-step into a clean MVVM module, and see how dependency injection makes your ViewModels easy to unit test. The video closes with practical advice on when to reach for more advanced patterns like Coordinator or Clean Architecture.
