Can I use this for CloudKit synchronization?

Absolutely. It covers CloudKit integration, conflict resolution strategies, and handling constraints like optional property requirements.

Does this skill support Swift 6 strict concurrency?

Yes, it focuses on modern Swift 6 patterns, specifically utilizing @MainActor and actor-based safety for database operations.

How does it handle relationship management?

The skill provides guidance on using @Relationship with delete rules like .cascade and .nullify, including how to maintain bidirectional integrity.

Does it provide migration paths from Core Data?

Yes, it includes patterns for dual-stack migrations, allowing you to transition safely from Core Data to SwiftData while keeping both running.
