Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

사용 사례

실전 활용법: ios-simulator-skill

Build, run, and screenshot the current flow

👤 iOS devs using Claude Code to iterate ⏱ ~5 min beginner

언제 쓸까: You changed a view and want to see it live without leaving the chat.

사전 조건

Xcode + simulator installed — Standard macOS iOS dev setup

흐름

Ask Claude to build and run

Use ios-simulator-skill. Build MyApp scheme for iPhone 16, launch, navigate to Settings, screenshot.✓ 복사됨

→ Compact build summary, then the screenshot
Iterate

I tweaked the padding — rebuild and re-screenshot.✓ 복사됨

→ Fast turn with minimal token overhead

결과: Tight build-iterate-view loop in Claude Code.

함정

Scheme name typo causes unclear error — Skill returns a compact list of available schemes on mismatch

함께 쓰기: filesystem

Drive a scripted UI flow for smoke testing

👤 iOS devs and QA ⏱ ~15 min intermediate

언제 쓸까: You want to verify a critical flow without writing full XCUITest scaffolding.

흐름

Describe the flow

Launch the app, tap 'Sign in', enter creds, tap the first row in the list, screenshot.✓ 복사됨

→ Claude uses accessibility labels to drive each step
Check WCAG compliance

Now run the accessibility audit on the current screen.✓ 복사됨

→ WCAG findings with fix suggestions

결과: A working smoke flow plus an a11y pass.

함정

Flow breaks when a label changes — Labels are more stable than coordinates, but still review after big UI refactors

Tail logs while reproducing a bug

👤 iOS devs chasing a flaky issue ⏱ ~10 min intermediate

언제 쓸까: A bug only repros in the simulator and you want the relevant logs.

흐름

Reproduce with filtered logs

Launch the app, tap through the crashing flow, tail logs filtered to error+warning.✓ 복사됨

→ Claude returns a trimmed log bundle and highlights the likely cause

결과: A targeted log excerpt and a hypothesis for the bug.

함정

Logs too noisy if severity filter not set — Default to error+warning; raise to info only when debugging

조합

다른 MCP와 조합해 10배 효율

ios-simulator-skill + filesystem

Skill runs the build; filesystem reads/writes the sources

Edit SettingsView.swift, then build and screenshot.✓ 복사됨

ios-simulator-skill + github

Reproduce an issue from a GitHub bug report in the simulator

Read issue #42, reproduce the steps in the simulator, attach screenshot to a comment.✓ 복사됨

도구

이 MCP가 노출하는 것

도구	입력	언제 호출
xcodebuild wrapper	scheme, destination	Any build request
Simulator driver (accessibility APIs)	element label/role + action	UI automation in the simulator
Screenshot capture	none (current screen)	Visual verification
Log tailing	severity filter, duration	Debugging runtime issues
Device lifecycle	boot/shutdown/create/reset	Fresh simulator state needed
Accessibility audit	current screen	A11y review

비용 및 제한

운영 비용

API 쿼터: None
호출당 토큰: Very low — compact build summaries + compressed screenshots are the main design goal
금액: Free — skill is local
팁: Keep screenshots at default compression; full-res screens eat context fast.

보안

권한, 시크릿, 파급범위

자격 증명 저장: No credentials in the skill. App-side secrets stay in your build config.

데이터 외부 송신: None — everything runs on local simulators

Simulators have access to your keychain if you've configured it — be careful with credentials during automation.

문제 해결

자주 발생하는 오류와 해결

'No such scheme'

Skill lists available schemes on mismatch; pick the exact name.

확인: xcodebuild -list -project MyApp.xcodeproj

Accessibility label not found

Add accessibilityIdentifier to the SwiftUI view — it's more stable than the visible label.

Simulator stuck booting

Use the device-lifecycle reset command; then re-boot.

확인: xcrun simctl list

대안

ios-simulator-skill 다른 것과 비교

대안	언제 쓰나	단점/장점
Direct xcodebuild + simctl	You don't mind the token bloat from raw output	No abstraction; verbose
XcodeBuildMCP	You prefer an MCP server with structured tools	MCP route; this skill is local scripts
