## What problem does it solve? SwiftData simplifies persisting, querying, and migrating structured app data so developers no longer manage low-level SQLite wiring, manual schema transformations, or brittle Core Data interoperability by hand.
## Core Features & Use Cases
### Quick Start Create @Model classes for your entities, attach a ModelContainer to the SwiftUI scene, and use @Query or ModelContext to insert, fetch, update, and save records.
High-intent search queries and answers about installing and using this skill.
To set up SwiftData persistence, define @Model classes for your data structures, attach a ModelContainer to your SwiftUI scene, and use @Query or ModelContext to insert, fetch, and save records.
SwiftData migrations require defining VersionedSchema stages and a SchemaMigrationPlan to perform lightweight or custom migrations, ensuring safe schema transformations and updates without data loss.
Yes, SwiftData supports CloudKit sync by applying CloudKit-compatible configurations to your ModelContainer, enabling synced or local-only stores for your iOS application data.
The best way to drive SwiftUI views is using @Query with FetchDescriptor and SortDescriptor patterns, which dynamically fetch, filter, and sort structured app data to populate lists and previews.
Optimize SwiftData large data imports by using batched enumeration, external storage for large blobs, history tracking, and transaction semantics to ensure atomic operations and reliable performance.
