is MVVM the preferred architecture for swiftui?

The content from the WWDC sessions does not explicitly state that MVVM (Model-View-ViewModel) is the preferred architecture for SwiftUI. However, SwiftUI is built on principles of declarative, compositional, and state-driven views, which align well with the MVVM architecture. This architecture is often used with SwiftUI because it helps manage state and data flow in a way that complements SwiftUI's declarative nature.

For more details on SwiftUI's capabilities and its interoperability with other frameworks, you can refer to the SwiftUI essentials session, which discusses SDK interoperability and how SwiftUI can be incrementally adopted in apps.
