iOS Devs: Device Hub misses a lot of features compared to Xcode's Simulator. For example: a shortcut to shake the device. Missing more features? Reply, and I'll see what I can do!

Xcode's Device Hub misses drag & drop support for files like certificates, screenshots and videos. Losing simple habits like this can annoy you as a developer who uses these tools daily. Let me fix it for you in RocketSim 🚀

My last few weeks: battling Xcode 27 with agentic support for RocketSim, testing in Codex, Cursor, Claude, while Device Hub replaces the Simulator, bringing all kinds of edge cases 🙈 My developer tools are getting better, but it's a long road. Thanks for all your feedback & support along the way!
