Samples

Sample Platforms High-level architecture Documented patterns
Adopting SwiftData for a Core Data app iOS, iPadOS, Mac Catalyst, macOS A Swift sample bundle with entry-bearing project variants Trips-Coexistence, Trips-CoreData, Trips-SwiftData, each leading to CoreData APIs. View-controller organization, Delegate or data-source callbacks, Actor-isolated state
Handling Different Data Types in Core Data iOS, iPadOS, Mac Catalyst A Swift sample with the source-visible chain AppDelegate → ViewController → ColorToDataTransformer → CoreData APIs. View-controller organization, Delegate or data-source callbacks
Linking Data Between Two Core Data Stores iOS, iPadOS, Mac Catalyst A Swift sample with the source-visible chain AppDelegate → FeedbackViewController → CoreData APIs. View-controller organization, Delegate or data-source callbacks
Sharing Core Data objects between iCloud users iOS, iPadOS, Mac Catalyst, macOS, watchOS A Swift sample bundle with entry-bearing project variants CoreDataCloudKitShare, CoreDataCloudKitShareOnWatch, each leading to CoreData APIs. View-controller organization, Delegate or data-source callbacks, Binding-based state propagation
Showcase App Data in Spotlight iOS, iPadOS, Mac Catalyst A Swift sample with the source-visible chain AppDelegate → FullImageViewController → PhotoProvider → CoreData APIs. View-controller organization, Protocol-oriented abstraction, Delegate or data-source callbacks
Synchronizing a local store to the cloud iOS, iPadOS, Mac Catalyst A Swift sample with the source-visible chain AppDelegate → DetailViewController → InjectableCLLocationManager → AttachmentProvider → CoreData / CoreDataCloudKitDemo APIs. View-controller organization, Protocol-oriented abstraction, Delegate or data-source callbacks
