what architecture does apple recommend for modern switfui apps?

Apple recommends using SwiftUI for modern app development across all of its platforms. SwiftUI is a declarative user interface framework that allows developers to build apps with a focus on describing the UI they want, while SwiftUI handles details like dark mode, dynamic type, and model changes. It is designed to be easy to learn and packed with advanced features, enabling code sharing across devices and platforms. SwiftUI supports incremental adoption, meaning you can integrate it into existing apps or use it to build new ones from the ground up.

For more details, you can refer to the SwiftUI essentials session, which covers the fundamentals and capabilities of SwiftUI.
