Swift language patterns and best practices including concurrency, performance, and modern idioms. Use for Swift language-level code review or architecture guidance.
npx skills add rshankras/claude-code-apple-skills --skill swift --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.
# Swift Development Swift language-level guidance that applies across all Apple platforms. ## When This Skill Activates Use this skill when the user: - Asks about Swift concurrency (async/await, actors, Sendable, TaskGroup) - Needs help with Swift 6 strict concurrency migration - Has data race or actor isolation errors - Asks about **InlineArray**, **Span**, or low-level memory performance - Wants to eliminate heap allocations or replace unsafe pointers - Asks about modern Swift patterns independent of any specific platform - Wants complexity/size limits (SwiftLint thresholds) on agent-written code ## Available Modules ### concurrency-patterns/ Swift concurrency architecture and patterns. - Swift 6.2 approachable concurrency features (incl. `nonisolated(nonsending)`, Apple's adoption doctrine) - Structured concurrency (async let, TaskGroup, .task modifier, task-local values) - Actors, isolation, reentrancy, @MainActor, Sendable - Runtime internals + profiling (cooperative pool, unsafe primitives, Swift Concurrency Instrument) - Continuations for bridging legacy APIs - Swift 6 strict concurrency migration guide ### concurrency/ Swift 6.2 concurrency **updates** reference — the what-

What does the swift-development skill do?
Swift language patterns and best practices including concurrency, performance, and modern idioms. Use for Swift language-level code review or architecture guidance.
How do I install it?
Run `npx skills add rshankras/claude-code-apple-skills --skill swift --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.
