swiftdata · prisma-labs-dev — Claude Code skill: SwiftData API reference
A reference skill for SwiftData. The agent searches four markdown files for answers on @Model, ModelContext, @Query and schema migrations.
npx skills add Prisma-Labs-Dev/apple-skills --skill swiftdata -a claude-codeWhat swiftdata does
The skill is user-invocable and runs in a forked context: it spins up an Explore subagent and hands it the doc search. Answers come back in two parts — a short summary plus the file paths holding the details. For @Model that is swiftdata-model.md, for @Query it is swiftdata-query.md.
Four files ship with it. swiftdata-index.md covers the framework overview and the API list, swiftdata-model.md the @Model macro, swiftdata-modelcontext.md CRUD through ModelContext, and swiftdata-query.md the @Query property wrapper. There is no dedicated file for schema migrations even though the description mentions them, so those questions land on the general material.
Worth installing if you write Swift and keep tabbing over to Apple's docs. Nothing beyond the markdown files gets pulled in.
What it helps with
- find how to declare a model with @Model
- recall the ModelContext methods for insert and delete
- work out how @Query filters and sorts a fetch
- get the file list with details on a specific API
Example prompts for the agent
- show me how to declare a model with @Model and a one-to-many relation
- how do I insert and delete an object through ModelContext?
- what does @Query do and how do I give it a predicate
