# iOS Simulator Skill

Build, test, and automate iOS applications using accessibility-driven navigation and structured data instead of pixel coordinates.

## Quick Start

```bash
# 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.

    - Optional verification
    - Options: `--udid`, `--name`, `--verify`, `--timeout`, `--all`, `--type`, `--booted`, `--json`

## 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.

**Screenshot Sizing**: Screenshots are resized to save tokens. Presets: `full` (3-4 tiles, ~5K tokens), `half` (1 tile, ~1.6K tokens, default), `quarter` (1 tile, ~800 tokens, less detail). Use `quarter` for quick visual checks, `half` for readable UI, `full` only when pixel-level detail matters. Scripts that capture screenshots (`app_state_capture.py`, `test_recorder.py`) default to `half`.

## Typical Workflow

1. Verify environment: `bash scripts/sim_health_check.sh`
2. Launch app: `python scripts/app_launcher.py --launch com.example.app`
3. Analyze screen: `python scripts/screen_mapper.py`
4. Interact: `python scripts/navigator.py --find-text "Button" --tap`
5. Verify: `python scripts/accessibility_audit.py`
6. 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)

## Documentation

- **SKILL.md** (this file) - Script reference and quick start
- **README.md** - Installation and examples
- **CLAUDE.md** - Architecture and implementation details
- **references/** - Deep documentation on specific topics
- **examples/** - Complete automation workflows

## 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.
