swiftDesign, implement, and review Swift APIs and Apple-platform code.
Swift is an agent skill from margelo/react-native-skills. Design, implement, and review Swift APIs and Apple-platform code. Use when working on .swift files, Swift types, Foundation or AVFoundation APIs, DispatchQueue, async/await, Task, actors, MainActor, thread-affine state, or Swift-backed React Native Nitro Module implementations.
Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Mobile, covering iOS development and Cross-platform mobile apps. It works with React Native. The repository describes itself as: The best react-native Agent Skills. Forget 10x, this is 100x.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 1e9e17b. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Swift loads about 3.2k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 1,557 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,557 words (~3,192 tokens).
“Use this skill for Swift code that needs strong API boundaries, predictable threading, and idiomatic Apple-platform integration. When the code is part of a Nitro Module, pair this with build-nitro-modules for generated specs, Promise mapping, and HybridObject constraints.”

Design, implement, and review Swift APIs and Apple-platform code. Swift is an agent skill from margelo/react-native-skills. Design, implement, and review Swift APIs and Apple-platform code.
Swift fits situations like: working on .swift files; AVFoundation APIs; thread-affine state; swift-backed React Native Nitro Module implementations.
Run `npx skills add margelo/react-native-skills --skill swift -a claude-code`. Or copy the skill folder (skills/swift in margelo/react-native-skills) into .claude/skills/swift in your project. Claude Code loads it when a task matches its description.
Run `npx skills add margelo/react-native-skills --skill swift -a codex`. Or copy the skill folder (skills/swift in margelo/react-native-skills) into .agents/skills/swift in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add margelo/react-native-skills --skill swift -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/swift, .gemini/skills/swift, .github/skills/swift and .opencode/skills/swift in your project.
SKILL.md names no scripts, command-line tools or credentials: Swift is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
No licence was found for Swift or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 3.2k tokens (SKILL.md is roughly 13k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Swift: Cometchat React Native Migration (cometchat/cometchat-skills, 129 stars), Mobile App Builder (revfactory/harness-100, 1.3k stars), Apple Design (vrcm-team/VRCM, 179 stars) and Expo Brownfield Integration (mweinbach/agent-coworker, 156 stars).
