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 xcodebuild output when possible.
• Load focused skill packs on demand. Do not dump every Swift rule into context.

First move

1. Detect surfaces: iOS, iPadOS, macOS, mixed web/native, SwiftPM, Xcode project/workspace, Tuist, XcodeGen, CocoaPods, or buildable folders.
2. Read references/workflow.md.
3. If the task involves setup or machine bootstrap, read references/install-and-bootstrap.md.
4. If the task involves building, running, simulator, tests, or debugging, read references/xcodebuildmcp.md.
5. Pick only the external skill packs relevant to the current task from references/skill-map.md.

Mode picker

User asks for...	Load
"Bootstrap iOS", "install my iOS skills", "one command"	install-and-bootstrap.md
Build, test, simulator, logs, debug, device install	xcodebuildmcp.md
SwiftUI screen, navigation, sheets, app wiring	skill-map.md SwiftUI entries
Animation, motion, "make it feel alive", loaders, delight	Also use swiftui-animation-match (interaction-to-animation matcher)
Async/await, actors, Sendable, Swift 6 migration	skill-map.md concurrency entries
Unit tests, Swift Testing, XCTest migration	skill-map.md testing entries
SwiftData, models, queries, migrations, CloudKit	skill-map.md SwiftData entries
Core Data stack, fetches, background contexts	skill-map.md Core Data entries
Slow builds, compiler time, project settings	SwiftLee Xcode Build Optimization in skill-map.md
Architecture/rules loader/advanced Swift discipline	Merowing rules in skill-map.md
App Intents, Siri, Shortcuts, widgets	Official Build iOS Apps plugin notes in skill-map.md
QA this iOS app	Also use running-bug-review-board and its iOS simulator playbook

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.
