description: 29 production-ready scripts for iOS app testing, building, and automation. Provides semantic UI navigation, build automation, accessibility testing, and simulator lifecycle management. Optimized for AI agents with minimal token output.

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.

Navigation Strategy

**Always prefer the accessibility tree over screenshots for navigation.** The accessibility tree gives you element types, labels, frames, and tap targets — structured data that's cheaper and more reliable than image analysis.

Use this priority: 1. `screen_mapper.py` → structured element list (5-7 lines, ~10 tokens) 2. `navigator.py --find-text/--find-type/--find-id` → semantic interaction 3. Screenshots → only for visual verification, bug reports, or visual diff

Screenshots cost 1,600–6,300 tokens depending on size. The accessibility tree costs 10–50 tokens in default mode.

29 Production Scripts

Build & Development (2 scripts)

1. **build_and_test.py** - Build Xcode projects, run tests, parse results with progressive disclosure

• Build with live result streaming
• Parse errors and warnings from xcresult bundles
• Retrieve detailed build logs on demand
• Options: `--project`, `--scheme`, `--clean`, `--test`, `--verbose`, `--json`

2. **log_monitor.py** - Real-time log monitoring with intelligent filtering

• Stream logs or capture by duration
• Filter by severity (error/warning/info/debug)
• Deduplicate repeated messages
• Options: `--app`, `--severity`, `--follow`, `--duration`, `--output`, `--json`

Device State (2 scripts)

3. **appearance.py** - Control simulator appearance: dark mode, Dynamic Type size, and locale/region

• Toggle light/dark theme via `xcrun simctl ui`
• Set Dynamic Type size with friendly aliases (XS through AX5)
• Write locale and region defaults; optional app restart via `--bundle-id`
• RTL flagged automatically for ar/he/fa/ur/yi locales
• Options: `--theme`, `--text-size`, `--locale`, `--region`, `--reset`, `--bundle-id`, `--udid`, `--json`, `--verbose`

4. **location.py** - Simulate GPS coordinates, named city presets, and GPX scenario playback

• Fix a coordinate with `--lat`/`--lng` or pick a city with `--city`
• Play a built-in scenario (City Run, Freeway Drive, etc.) via `--gpx <scenario>`
• Animate multi-waypoint paths with configurable speed via `--waypoints` and `--speed`
• Clear simulated location with `--clear`; list available scenarios with `--list-scenarios`
• Options: `--lat`, `--lng`, `--city`, `--gpx`, `--waypoints`, `--speed`, `--clear`, `--list-scenarios`, `--udid`, `--json`, `--verbose`
