Should I use view models with SwiftUI?

Using view models with SwiftUI can be beneficial, especially when you want to manage and organize the state and logic of your views more effectively. SwiftUI views are declarative, compositional, and state-driven, which means they are designed to reflect the current state of your data. View models can help encapsulate this state and the logic that manipulates it, making your code more modular and testable.

In the SwiftUI essentials session, it is highlighted that SwiftUI views are value types defined using structs, and they are descriptions of what the current state of the UI should be. This makes it easy to break up one view into multiple views without hurting performance, which aligns well with the use of view models to manage state and logic separately from the view layer.

Overall, while SwiftUI itself does not require the use of view models, they can be a useful pattern to adopt for better code organization and separation of concerns.
