Core Data is an AI Engineering skill for Claude Code, published by dpearson2699 in swift-ios-skills.
Core Data helps build and review persistence for apps using NSPersistentContainer, background contexts, fetched results controllers, batch operations, and staged migrations. Use it when working on Core Data threading, history tracking, or list-driven UI without SwiftData.
Core Data is cataloged under AI Engineering on DirSkills. Core Data comes from a repository tagged accessibility, agent-skills, ai-coding, apple and claude-code.

Core Data is one of 25 skills that DirSkills catalogs from dpearson2699/swift-ios-skills, the repository it ships in. Its siblings there include AVKit, Accessory Setup Kit and ActivityKit. Each one is a separate skill with its own page in this directory, installs the same way Core Data does, and is maintained by dpearson2699 in that same repository. The rest of the collection is listed on the dpearson2699/swift-ios-skills page.
Core Data ranks #1367 by stars among the 2451 AI Engineering skills in this catalog. The most-starred ones next to it are Architecture Decision Records, AI-First Engineering and Agentic OS. DirSkills ranks by the star count of the repository each skill ships in, so that order reflects how popular those repositories are rather than any review of Core Data against them. Open each page to compare what they document and how they install.
