SwiftUI is Apple’s new declarative framework for building user interfaces for all Apple devices. This framework can be broken down into two essential components: views and state. By Amisha I.
State management is an integral part of SwiftUI development, and there are many different ways of working with the state. In which State represents the data associated with a view. In this article we are going to learn about a state holder to separate business logic from UI components. ViewModel has a longer lifecycle than the view so ViewModel can preserve its state across UI changes.
For simplicity, author divided this post into 3 sections:
- Add data layer – Responsible for fetching data from API
- Add ViewModel – Responsible for managing the state of the screen
- Add View – Actual UI representation that users will see
This is one of the ways to manage the state, however, you should explore other options as well once you are familiar with these basics. Good read!
