Can it help with migrating from Core Data?

Absolutely. It provides patterns for coexisting with legacy Core Data stacks and strategies for migrating data to SwiftData using VersionedSchema and MigrationPlan.

Does it include support for CloudKit?

Yes, it includes guidance on configuring ModelConfiguration for CloudKit database synchronization and adhering to CloudKit-compatible schema requirements.

Does this skill support the latest Swift 6 concurrency features?

Yes, it specifically focuses on Swift 6.3 patterns, emphasizing actor-based data handling with @ModelActor and the use of Sendable PersistentIdentifiers across boundaries.

What version of iOS is this skill optimized for?

The skill is optimized for modern development targeting iOS 26 and later, utilizing the newest SwiftData features like compound uniqueness and relationship enhancements.

How does it handle background data operations?

The skill promotes the use of @ModelActor to encapsulate background tasks, ensuring that ModelContext operations are performed on the correct actor to prevent concurrency crashes.

Implements, reviews, and optimizes modern data persistence layers for iOS 26+ applications using SwiftData and Swift 6.3.

This skill provides specialized guidance for architecting robust data layers in modern iOS applications by leveraging SwiftData's tight integration with Swift 6.3 and SwiftUI. It enables Claude to assist with the entire data lifecycle, from defining @Model classes with complex relationships and unique constraints to implementing advanced concurrency patterns using @ModelActor. Whether you are setting up CloudKit synchronization, orchestrating multi-stage schema migrations, or writing type-safe queries with #Predicate, this skill ensures your implementation follows Apple's latest best practices for performance and thread safety.
