Custom and third-party types can now be persisted using the Codable protocol via a new @Attribute(.codable) modifier, though such properties cannot be used for filtering or sorting and don't support automatic migrations. The @Query property wrapper gains a sectionBy parameter for grouping fetched results into SwiftUI list sections. Two new observer types are introduced: ResultObserver, which mirrors @Query functionality but works outside SwiftUI contexts, and HistoryObserver, which monitors persistent store transaction history to help sync data with external systems like remote servers. ## Full article daily.dev links to this article rather than hosting it.
