Feature branch in one window. Hotfix in another. PR review in a third. With multiple AI coding sessions pushing builds to different simulators, it became very easy to lose track of what branch a running build actually came from.
The iOS Simulator gives you no branch context - every window looks identical.
I built a small free macOS utility that overlays the current git branch directly on the Simulator window.
It maps the running app to its artifacts in DerivedData, resolves the originating project path, then reads the active git branch from that directory and renders it as an overlay on the Simulator window.
No changes to your project are required - it just adds context at a glance.
This has already saved me from debugging the wrong branch several times.
Would love feedback from other iOS developers who've experienced this problem or use parallel AI workflows.

Happy to answer technical questions.
