SwiftData defines data models using the @Model macro with @Attribute and @Relationship annotations to specify constraints and connections. This enables structured data persistence without boilerplate, supporting efficient querying and schema management in iOS applications.
SwiftData querying uses #Predicate with FetchDescriptor to filter and retrieve data from the ModelContext. This provides type-safe filtering for your data models, allowing complex queries to be executed efficiently within your SwiftUI views or background actors.
SwiftData supports CloudKit synchronization to keep data consistent across devices. Configuring the ModelContainer appropriately enables automatic syncing for your data models, ensuring user data stays updated across their iOS devices.
SwiftData handles background data operations using the @ModelActor annotation. This isolates ModelContext access for concurrent tasks, ensuring thread-safe data persistence without blocking the main UI thread during complex data processing.
Migrating Core Data to SwiftData involves planning schema migrations using ModelContainer configuration. This enables incremental adoption of modern data persistence while maintaining compatibility with existing data structures and ensuring data continuity.
