Does it provide debugging assistance?

Yes, it includes a comprehensive list of launch arguments for SQL debugging, migration tracking, and detecting concurrency violations.

Does this skill support SwiftUI integration?

Yes, it includes specific patterns and boilerplate for integrating Core Data with SwiftUI views using @FetchRequest and FetchedResults.

Can I use this for iCloud data synchronization?

Absolutely. The skill provides detailed configurations for NSPersistentCloudKitContainer and explains schema migration rules for CloudKit.

How does it handle thread safety?

It utilizes Swift actors for the PersistenceController and provides patterns for background context operations to ensure the main UI thread remains responsive.

Mobile Development

Implements robust Core Data persistence patterns for macOS and iOS applications, covering stack setup, CRUD, and CloudKit synchronization.

This skill provides a comprehensive library of Core Data implementation patterns designed for modern macOS and iOS development. It offers standardized approaches for setting up actor-based persistence controllers, managing background contexts, and executing complex fetch requests. Beyond basic CRUD operations, it provides specialized guidance on advanced features like CloudKit integration, derived attributes for performance optimization, and rigorous data integrity constraints, making it an essential tool for building data-driven Apple platform applications.
