At WWDC 2025, SwiftData was highlighted in several sessions, showcasing its capabilities and improvements. In the session titled "SwiftData: Dive into inheritance and schema migration," SwiftData was demonstrated using a sample app called Trips, which is written in SwiftUI. The session covered how to use SwiftData for persistence, schema migration, graph management, and synchronization with CloudKit. You can learn more about this in the session SwiftData: Dive into inheritance and schema migration (00:00:57).
Additionally, the "Platforms State of the Union" session mentioned enhancements to SwiftData, including model subclassing, entity inheritance, and support for additional data types like AttributedString. These updates make SwiftData more flexible and powerful for developers working with data models in SwiftUI.
