This repository offers a comprehensive suite of 27 scripts, optimized for both human developers and AI agents, to streamline iOS development workflows. It covers both Xcode builds, via `xcodebuild`, for compiling, testing, and parsing results with progressive error disclosure, and Simulator interaction, via `xcrun simctl` and `idb`, for semantic UI navigation, accessibility testing, and device lifecycle management. A key benefit is its token-efficient output, which drastically reduces the amount of information LLMs need to process, saving on token wastage and focusing agent conversations. ## Installation

Via Plugin Marketplace (Recommended)

In Claude Code, use the following commands: /plugin marketplace add conorluddy/ios-simulator-skill /plugin install ios-simulator-skill@conorluddy

Via Git Clone

For personal or project-specific installations: bash # Personal installation git clone https://github.com/conorluddy/ios-simulator-skill.git ~/.claude/skills/ios-simulator-skill # Project installation git clone https://github.com/conorluddy/ios-simulator-skill.git .claude/skills/ios-simulator-skill After cloning, restart Claude Code for the skill to load automatically.

Prerequisites

Ensure your system meets these requirements: * macOS 12+ * Xcode Command Line Tools (`xcode-select --install`) * Python 3 * IDB (optional, for interactive features: `brew tap facebook/fb && brew install idb-companion`) * Pillow (optional, for visual diffs: `pip3 install pillow`) ## Examples The skill's operational limits are tunable via `IOS_SIM_*` environment variables, allowing adaptation to different environments, from local development to slow CI runners. Here are some examples: * **Slow GitHub Actions macOS runner**: Give boot up to 10 minutes. bash IOS_SIM_BOOT_TIMEOUT=600 python scripts/simctl_boot.py --wait-ready * **Monorepo with hundreds of warnings**: See them all in verbose mode. bash IOS_SIM_BUILD_VERBOSE_CAP=500 python scripts/build_and_test.py --verbose * **Complex Settings-style screen**: Return more tappable elements. bash IOS_SIM_MAX_ELEMENTS=100 python scripts/navigator.py --list-tappable * **Snappy app**: Cut tap-settle delay in half for faster E2E runs. bash IOS_SIM_TAP_SETTLE_MS=250 python scripts/navigator.py --find-text "Login" --tap * **Long CI pipeline**: Keep cache entries valid for the whole job. bash IOS_SIM_CACHE_TTL_HOURS=8 python scripts/build_and_test.py --project MyApp.xcodeproj You can also export these variables once for the entire session: bash export IOS_SIM_BOOT_TIMEOUT=600 export IOS_SIM_LOG_TAIL=500 export IOS_SIM_MAX_ELEMENTS=50 # … all subsequent scripts honor them ## Why Use It The `ios-simulator-skill` offers several compelling advantages for developers and AI agents working with iOS applications: * **Optimized for AI Agents**: Specifically designed for Claude Code, it enables AI to interact with iOS simulators and Xcode builds efficiently, reducing the cognitive load and token cost for LLMs. * **Token Efficiency**: Features like progressive disclosure for build logs, optimized screenshot compression, and accessibility-first UI navigation drastically cut down on token consumption, making AI interactions more cost-effective and faster. * **Robust UI Interaction**: Instead of fragile pixel-coordinate tapping, the skill uses iOS accessibility APIs for semantic navigation, ensuring interactions are robust and resilient to UI changes. For more details on accessibility-first navigation for AI agents, refer to [AI-Accessible Apps](https://www.conor.fyi/writing/ai-access){:target="_blank"}. * **Comprehensive Tooling**: With 27 specialized scripts, it provides extensive capabilities for build management, device state manipulation, app navigation, testing, privacy management, and simulator lifecycle control. * **Configurable Environment**: Nearly every operational limit is tunable via environment variables, allowing fine-grained control to adapt the skill's behavior to diverse development and CI/CD environments. * **Proven Reliability**: Tested using Claude Code evals, the skill demonstrates a 100% pass rate, ensuring its reliability and effectiveness in automated workflows. ## Links * **GitHub Repository**: [https://github.com/conorluddy/ios-simulator-skill](https://github.com/conorluddy/ios-simulator-skill){:target="_blank"}
