Most coding agents can write iOS code, but testing what they built is still awkward. I built Lys around that missing loop. Agents can use the simulator, test real flows and see runtime issues. TestFlight is built in too, so tester feedback, screenshots and device context can go straight to an agent to fix. I also built a testing SDK for Swift and Expo/React Native to make apps easier for agents to test reliably. Lys is free and open-source.

Hey Product Hunt!
I built Lys because iOS development with coding agents still feels pretty awkward. Agents are getting really good at writing code, but testing what they built still means jumping between Xcode, simulators and other tools.
I wanted the agent to actually use the app, test real flows and see what happens at runtime. So I built a testing SDK for Swift and Expo/React Native and started building Lys around that workflow.
While building it, I also got annoyed by how disconnected TestFlight and App Store Connect are from the development loop. So Lys now brings those in too. You can see tester feedback and send the screenshot, device info and context straight to your agent to fix.
It’s still early and there are things to improve, but I’m using it myself and wanted to put it out there.
Lys is completely free and open-source. Would love to hear what you think!
