iOS Simulator Skill
Build, test, and automate iOS applications using accessibility-driven navigation and structured data instead of pixel coordinates.
Quick Start
# 1. Check environment
bash scripts/sim_health_check.sh
# 2. Launch app
python scripts/app_launcher.py --launch com.example.app
# 3. Map screen to see elements
python scripts/screen_mapper.py
# 4. Tap button
python scripts/navigator.py --find-text "Login" --tap
# 5. Enter text
python scripts/navigator.py --find-type TextField --enter-text "user@example.com"
All scripts support --help for detailed options and --json for machine-readable output.

Common Patterns
Auto-UDID Detection: Most scripts auto-detect the booted simulator if --udid is not provided.
Device Name Resolution: Use device names (e.g., "iPhone 16 Pro") instead of UDIDs - scripts resolve automatically.
Batch Operations: Many scripts support --all for all simulators or --type iPhone for device type filtering.
Output Formats: Default is concise human-readable output. Use --json for machine-readable output in CI/CD.
Help: All scripts support --help for detailed options and examples.
Typical Workflow
- Verify environment:
bash scripts/sim_health_check.sh - Launch app:
python scripts/app_launcher.py --launch com.example.app - Analyze screen:
python scripts/screen_mapper.py - Interact:
python scripts/navigator.py --find-text "Button" --tap - Verify:
python scripts/accessibility_audit.py - Debug if needed:
python scripts/app_state_capture.py --app-bundle-id com.example.app
Requirements
- macOS 12+
- Xcode Command Line Tools
- Python 3
- IDB (optional, for interactive features)

Key Design Principles
Semantic Navigation: Find elements by meaning (text, type, ID) not pixel coordinates. Survives UI changes.
Token Efficiency: Concise default output (3-5 lines) with optional verbose and JSON modes for detailed results.
Accessibility-First: Built on standard accessibility APIs for reliability and compatibility.
Zero Configuration: Works immediately on any macOS with Xcode. No setup required.
Structured Data: Scripts output JSON or formatted text, not raw logs. Easy to parse and integrate.
Auto-Learning: Build system remembers your device preference. Configuration stored per-project.
Use these scripts directly or let Claude Code invoke them automatically when your request matches the skill description.
