Argent

Argent is an agentic toolkit that gives your AI assistant direct access to iOS Simulators. Ask it to tap a button, run a profiler or reproduce an issue manually - all from within your CLI, without switching context.

npx @swmansion/argent init

Capabilities

• Autonomous iOS development - Allow your agent to work with iOS apps on its own - let it build, open, interact with the app and debug it. Ask for reproducing issues, testing features manually, profiling your app and much more, without ever interrupting your work.
• UI interaction - Give your agent full control toolkit - tapping, swiping, pinching, typing, gestures, hardware buttons and all other gears included. Let it navigate your app exactly as a user would, without lifting a finger.
• Profiling with batteries included - Argent can perform and analyze both React-Native and Xcode Instruments profiling sessions. Get comprehensive summaries and ask to optimise your app where you find fit.
• Debugging and diagnostics - Let your agent inspect logs, capture crash reports, and reproduce failing states on the simulator, so you can jump straight to the fix.
• React Native out of the box - Argent works with React Native apps natively, so your agent can build, launch, and iterate on your RN project the same way it would any iOS app - no extra setup required.

Tip: Once installed, ask your assistant "What can Argent do?" - it will walk you through all capabilities available.

Privacy

Argent does not collect or transmit any user data. No telemetry, no analytics, no crash reporting.

• Argent integrates with your agent locally over MCP stdio.
• Its internal tools are not reachable from outside your machine.
• The only outbound network call we make is the version check against our public npm package, which sends no user data and fails gracefully if blocked.
