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
xcodebuild output 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 cursor
After 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.
