swiftui and data | Ask WWDC

SwiftUI and SwiftData are closely integrated to help developers build efficient and modern apps. SwiftData is a framework that simplifies building your app's model layer and persisting data across app launches. It provides features like schema modeling, migration, graph management, and synchronization with CloudKit. SwiftData can be easily adopted in SwiftUI apps by importing the framework and using the model macro to define models. This allows views to query and display data dynamically, as demonstrated in the "Trips" app example from the session What’s new in SwiftData.

SwiftUI, on the other hand, is a declarative framework that focuses on building user interfaces. It is state-driven, meaning that it automatically updates the UI when the underlying data changes. This is achieved through state management tools like state and binding, which create dependencies between data and views. SwiftUI's capabilities extend beyond views, allowing for the creation of custom layouts, animations, and even integration with other frameworks like SwiftData for persistent data models. This is discussed in the session SwiftUI essentials.

Both frameworks are designed to work seamlessly together, enabling developers to build robust and interactive applications with ease.
