What coding agents get wrong in Swift
Agents write Swift 5 code that fails Swift 6 strict concurrency checks. They mark types @unchecked Sendable to silence the compiler, mix XCTest with Swift Testing, and hide dependencies behind singletons that tests cannot replace.
Skills that help
Skills for Swift concurrency review, Swift Testing (@Test, #expect), protocol-based dependency injection, and performance audits.
Cursor rules: the database holds 10 Cursor rule files (.mdc) tagged Swift (modern-swift, swift-argument-parser, swift-observable, swift-observation, swift-testing-api, swift-testing-playbook, and more). Cursor reads them from .cursor/rules/. Other agents load SKILL.md skills, so most picks here are skills.
3 picks to start with
1. swift-concurrency-expert
Swift Concurrency review and remediation for Swift 6.2+.
npx skills add Dimillian/Skills --skill swift-concurrency-expert
2. swift-testing-expert

npx skills add AvdLee/Swift-Testing-Agent-Skill --skill swift-testing-expert
3. swift-protocol-di-testing
Protocol-based dependency injection for testable Swift code , mock file system, network, and external APIs using focused protocols and Swift Testing.

These 3 fit Swift in general. The scan box opens with a sample Swift description you can edit. A scan reads your repo or description, shows the match count and 2 picks free, and the full curated list (up to 30 picks with install commands, reasons and overlap notes) costs $9 once.
Where each agent loads Swift skills
- Claude Code: project folder
.claude/skills/, install flag--agent claude-code - Cursor: project folder
.cursor/skills/ or .agents/skills/, install flag--agent cursor - Codex: project folder
.agents/skills/, install flag--agent codex - GitHub Copilot: project folder
.github/skills/ or .agents/skills/, install flag--agent github-copilot
npx skills add owner/repo --skill skill-name --agent claude-code
How we count
We match project tags against 99,639 skills from 7,206 public GitHub repos (refreshed 2026-10-18). A skill built for another framework or language is left out, and so is a skill below our relevance floor. The picks on this page come from the ranked list for these tags. We favor broad practice skills over single-task ones. Licenses are shown as each repo declares them. Read a skill before you install it.
Questions
What agent skills should I use for Swift?
Start with a broad practice skill built for Swift, then add skills for testing and review. In our database 82 skills are tagged for Swift and 332 skills match a typical Swift project. The picks on this page are a place to start. A scan of your repo ranks the full list for your tasks.
How is this page different from the iOS page?
This page covers the Swift language: concurrency, tests and code structure. The iOS page covers apps: SwiftUI screens, UI tests and App Store steps.
Are there Cursor rules for Swift?
Yes. The database holds 10 Cursor rule files (.mdc) tagged Swift. Cursor loads them from .cursor/rules/. Claude Code, Codex and Copilot do not read .mdc rules, so pick SKILL.md skills for those agents.
Where do Swift skills go for Claude Code, Cursor, Codex and Copilot?
Claude Code reads .claude/skills/, Cursor reads .cursor/skills/ or .agents/skills/, Codex reads .agents/skills/, and GitHub Copilot reads .github/skills/ or .agents/skills/. The install command takes --agent with the agent name and copies the skill folder there.
Why 3 picks here?
The right list depends on your exact stack and tasks. Run a free scan for your project to see its match count and 2 picks. The full curated list is $9 once.
