Axiom Core Data

charleswiltgen/axiom

This is part of the axiom skill collection that helps Claude work with Apple's Core Data framework. It's positioned as the fallback option when SwiftData won't cut it, either because you're targeting iOS 16 and earlier or need advanced features the newer framework doesn't handle yet. The skill includes a decision tree to help you pick between Core Data and SwiftData, which is genuinely useful since that choice trips up a lot of developers. Worth noting it failed one security audit (Gen Agent Trust Hub) while passing Socket and Snyk. If you're maintaining legacy iOS apps or need Core Data's full feature set, this gives Claude the context to help without constantly explaining the basics.
