A SwiftData reference for Claude Code that targets iOS 26+ and the latest features of Apple's persistence framework. If you're building SwiftUI apps with @Model classes and @Query, this gives your agent the context it needs to work with Swift's modern data layer instead of fumbling with outdated Core Data patterns. The focus on current iOS versions means you won't get buried in legacy API baggage, which is refreshing. Part of the axiom collection from charleswiltgen, which has picked up nearly a thousand GitHub stars. Passed security audits from Gen Agent Trust Hub, Socket, and Snyk.
