What it does
Bootstrap iOS is an agent skill from RayFernando1337/rayfernando-skills. Bootstrap agents for iOS, iPadOS, macOS, Swift, SwiftUI, SwiftData/Core Data, Swift Testing, Xcode build/test/debug, Simulator, App Intents, or XcodeBuildMCP work. Use before building, fixing, refactoring, QAing, or setting up Apple-platform repos, and when asked to load/install Ray's iOS skills or bootstrap iOS.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `references/install-and-bootstrap.md`, `references/skill-map.md` and `references/sources.md`).
It sits in Mobile, covering iOS development. It works with iOS, Xcode, SwiftUI and macOS. The repository describes itself as: Ray Fernando's collection of Skill files for AI coding agents. First up: running-bug-review-board, a real-user QA workflow with a Bug Review Board (BRB) feedback loop. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve iOS development
Example prompts
- “/bootstrap-ios”
Requirements
- A Bash shell
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Detect surfaces: iOS, iPadOS, macOS, mixed web/native, SwiftPM, Xcode
- Read references/workflow.md.
- If the task involves setup or machine bootstrap, read
- If the task involves building, running, simulator, tests, or debugging,
- Pick only the external skill packs relevant to the current task from
What it can do on your machine
Read from SKILL.md and the folder at commit 952eaaa. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
bash
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Bootstrap iOS loads about 1.1k tokens when it runs, and up to ~4.4k if it reads all its reference files. Until then it costs about 82 tokens; SKILL.md has 498 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.
Safety
Auto-check passed
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); the scripts in this folder are not scanned.

- description
- Bootstrap agents for iOS, iPadOS, macOS, Swift, SwiftUI, SwiftData/Core Data, Swift Testing, Xcode build/test/debug, Simulator, App Intents, or XcodeBuildMCP work. Use before building, fixing, refactoring, QAing, or setting up Apple-platform repos, and when asked to load/install Ray's iOS skills or bootstrap iOS.
Bootstrap iOS
Use this as the single entry point before touching an Apple-platform app. It is a router skill: discover the project, load only the references needed for the current job, verify that build/test tools exist, then act.
The default posture is conservative:
- Build and test before judging code.
- Prefer modern Swift, SwiftUI, Observation, Swift Concurrency, Swift Testing, SwiftData, and current Xcode APIs.
- Avoid deprecated APIs unless the deployment target requires them.
- Use XcodeBuildMCP or an agent-friendly build script instead of raw,
unfiltered
xcodebuildoutput when possible. - Load focused skill packs on demand. Do not dump every Swift rule into context.
First move
- Detect surfaces: iOS, iPadOS, macOS, mixed web/native, SwiftPM, Xcode project/workspace, Tuist, XcodeGen, CocoaPods, or buildable folders.
- Read references/workflow.md.
- If the task involves setup or machine bootstrap, read references/install-and-bootstrap.md.
- If the task involves building, running, simulator, tests, or debugging, read references/xcodebuildmcp.md.
- Pick only the external skill packs relevant to the current task from references/skill-map.md.

When installing external skills
Do not silently modify the user's machine. If the user asks to install or bootstrap, explain what will be installed, then use the helper script in dry-run first:
bash scripts/bootstrap-ios-skills.sh --dry-run --agent cursorAfter the user confirms, run without --dry-run. The helper is idempotent and
keeps optional/non-GitHub sources as instructions instead of pretending it can
install them. After a real install it verifies every expected skill actually
landed and is complete (every references/, scripts/, and assets/ file
cited by each SKILL.md exists on disk) and fails loudly with reinstall
instructions if any skill is missing entirely or installed shallow. See
references/install-and-bootstrap.md.
Verification
Before reporting an Apple-platform task done:
- Confirm the scheme/project/workspace you used.
- Run the smallest meaningful build or test command.
- Capture build errors from clean output, not raw wall-of-text logs.
- If using XcodeBuildMCP, name the tool/command used.
- If build/test is blocked by signing, missing simulator, or missing Xcode, report the blocker with the exact next command to fix it.
- For UI work, run in Simulator when feasible and capture enough evidence for the next agent to verify.

When should I use Bootstrap iOS?
Bootstrap iOS fits situations like: tasks that involve iOS development.
How do I install Bootstrap iOS in Claude Code?
Run `npx skills add RayFernando1337/rayfernando-skills --skill bootstrap-ios -a claude-code`. Or copy the skill folder (plugins/bootstrap-ios/skills/bootstrap-ios in RayFernando1337/rayfernando-skills) into .claude/skills/bootstrap-ios in your project. Claude Code loads it when a task matches its description.
How do I install Bootstrap iOS in Codex?
Run `npx skills add RayFernando1337/rayfernando-skills --skill bootstrap-ios -a codex`. Or copy the skill folder (plugins/bootstrap-ios/skills/bootstrap-ios in RayFernando1337/rayfernando-skills) into .agents/skills/bootstrap-ios in your project. Codex loads it when a task matches its description.
Can I use Bootstrap iOS in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add RayFernando1337/rayfernando-skills --skill bootstrap-ios -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/bootstrap-ios, .gemini/skills/bootstrap-ios, .github/skills/bootstrap-ios and .opencode/skills/bootstrap-ios in your project.
What does Bootstrap iOS need to run?
Going by SKILL.md and its folder, Bootstrap iOS needs a shell for the scripts in its folder and the command-line tools its instructions call (bash). Our summary lists: A Bash shell.
Does Bootstrap iOS access the network?
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.
Is Bootstrap iOS safe to install?
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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Bootstrap iOS use?
Bootstrap iOS is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Bootstrap iOS use?
About 1.1k tokens (SKILL.md is roughly 4.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.3k tokens, read only when the agent opens those files.
What are the alternatives to Bootstrap iOS?
Skills that share tags, products or a category with Bootstrap iOS: Swift Development (aiskillstore/marketplace, 430 stars), SwiftUI Design Skill (Wholiver/swiftui-design-skill, 210 stars), Snapshot Tests (microsoft/SwiftStreamingMarkdown, 378 stars) and Flowdeck (SwiftedMind/Tessera, 116 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
