Branch context overlay for iOS Simulator; solves real pain for parallel workflows.

Strengths
  • •Solves a genuine, recurring pain point for power users running multiple simulator instances.
  • •Minimal scope and execution: reads git state from DerivedData, overlays branch name—no project changes needed.
  • •Pending build indicator catches a second real problem: stale builds after branch switching.
Weaknesses
  • •Niche audience: only useful if you're already juggling multiple worktrees or AI coding sessions.
  • •Single-platform macOS tool, appeals to a subset of an already iOS-developer-only audience.
Target Audience

iOS developers using git worktrees, multiple clones, or parallel AI coding sessions

Post Description

I kept running into the same problem while working across multiple worktrees and clones.

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.
