swiftdata
SwiftData skills — class inheritance patterns for hierarchical models, type-based querying, polymorphic relationships, and inheritance-vs-enum decisions. Use when designing SwiftData model hierarchies.
npx skills add rshankras/claude-code-apple-skills --skill swiftdata --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# SwiftData Skills SwiftData modeling patterns beyond the basics. ## When This Skill Activates Use this skill when the user: - Designs **hierarchical SwiftData models** (class inheritance) - Needs **type-based or polymorphic queries** - Weighs **inheritance vs enum** for model variants ## Available Skills Paths are relative to THIS file's directory — skills run with cwd set to the user's project, so resolve each path from this SKILL.md's own location. | Skill | Read | Covers | |-------|------|--------| | inheritance | `inheritance/SKILL.md` | Class inheritance, polymorphic relationships, type-based querying, inheritance-vs-enum | ## How to Route 1. Read `inheritance/SKILL.md` (relative to this file) plus any reference files it lists. 2. Apply the guidance to the user's code. For broader macOS SwiftData architecture, see also `../macos/swiftdata-architecture/SKILL.md`.

What does the swiftdata skill do?
SwiftData skills — class inheritance patterns for hierarchical models, type-based querying, polymorphic relationships, and inheritance-vs-enum decisions. Use when designing SwiftData model hierarchies.
How do I install it?
Run `npx skills add rshankras/claude-code-apple-skills --skill swiftdata --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From rshankras/claude-code-apple-skills, a repository with 589 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
