This Skill resolves complex challenges in SwiftData implementation, including concurrency management, CloudKit synchronization, and schema migration, ensuring robust and performant data persistence.
Use the swiftdata-expert skill to review my current model definitions and suggest the necessary migration plan for adding a new property to my CloudKit-synced entity.

Implement SwiftData concurrency using the @ModelActor macro to safely manage ModelContext access across isolated execution domains. This pattern ensures strict Swift 6 concurrency compliance while maintaining efficient data persistence.
Migrate SwiftData schemas safely by defining a VersionedSchema and creating a SchemaMigrationPlan. This approach provides step-by-step strategies to transition between models and prevents data loss during production updates.
Yes, SwiftData supports CloudKit synchronization to sync user data across devices. You can safely refactor a local-only cache store into a CloudKit-synced data model without breaking existing production data.
Yes, adhering to strict Swift 6 concurrency rules is required for safe ModelContainer and ModelContext operations. This ensures data races are prevented and efficient data management strategies are maintained.
Review your model definitions and generate a SchemaMigrationPlan to add the new property. This ensures the CloudKit-synced entity updates correctly across versions without corrupting existing data.
