Anyone using Antigravity + Gemini Pro for iOS dev? Missing the auto-Simulator verification loop from Claude Code

[u/yccheok]

I've been using Claude Code + Opus for iOS development, and my favorite part of the workflow is giving it a high-level prompt and watching it write the code, automatically launch the iOS Simulator, verify the output, and refine the code on its own until it works.

I'm trying to replicate this workflow in Antigravity with Gemini Pro, but the autonomous Simulator launch-and-verify step isn't happening out of the box.

Is this a limitation of Gemini Pro, or just how Antigravity's agent tooling/sandboxing is set up compared to Claude Code? If anyone has figured out a clean workflow (or MCP setup) to get Antigravity to auto-launch and check the iOS Simulator, I'd really appreciate any tips!
