should I use mvvm

The Model-View-ViewModel (MVVM) pattern is a popular architectural pattern for building user interfaces, especially in the context of SwiftUI. SwiftUI itself is designed to work well with state-driven architectures, which aligns with the principles of MVVM.

In the session SwiftUI essentials, it is highlighted that SwiftUI views are declarative, compositional, and state-driven. This means that SwiftUI automatically keeps your UI up to date as your view state changes over time, which reduces boilerplate code and update bugs. This is a core concept of MVVM, where the ViewModel manages the state and logic, and the View reflects this state.

Additionally, SwiftUI's use of bindings and state properties, as discussed in the same session, supports the separation of concerns that MVVM promotes. For example, a view can use a @State property to manage its own state or a @Binding to reflect the state managed by a ViewModel.

Therefore, using MVVM with SwiftUI can be a good choice as it leverages SwiftUI's strengths in managing state and updating the UI declaratively. If you are building a new app or migrating an existing one, incorporating MVVM can help you create a more maintainable and scalable codebase.
