RocketSim - Build Apps Faster
RocketSim enhances the iOS Simulator with tools for testing, debugging, captures, accessibility, app actions, and more. It helps iOS developers move faster by making common Simulator workflows easier to inspect, automate, and repeat.
Developers use RocketSim to:
- Inspect and debug simulator behavior faster
- Trigger app actions and test flows without leaving their coding environment
- Capture screenshots and recordings with less manual work
- Automate simulator interaction through the RocketSim CLI and bundled agent skill
RocketSim Agent Skill
The RocketSim agent skill gives AI coding tools a reliable way to work with the iOS Simulator through RocketSim. It detects the installed RocketSim version, uses the matching RocketSim CLI, and enables agents to inspect what is visible on screen before interacting with the app.
In practice, this gives your agents eyes. Instead of guessing with brittle simulator automation, they can use RocketSim to understand the current UI state and interact with it efficiently using the same stateful tooling that powers RocketSim itself.
This is especially useful if you want an agent to:
- Navigate and test iOS Simulator apps
- Read visible accessibility elements before interacting
- Tap, type, swipe, and trigger flows more reliably
- Use the RocketSim version already installed on your machine
The RocketSim Agent Skill now lives in its own repository with full installation instructions, packaging metadata, and release workflow:
