# Xcode Build Benchmark

Know whether your build actually got faster, instead of guessing

## What this does

You changed something and you think builds are faster, but you don't actually know. This times your Xcode clean and incremental builds the same way each run and saves the results, so before and after can be compared. Reach for it before optimising anything, and again afterwards.

### Top 3 things it does for you

- Measure how long my builds really take
- Get a baseline before I change anything
- Compare build times before and after a change

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Xcode Build Benchmark

This benchmarks Xcode clean and incremental builds using repeatable inputs, so runs can be compared against each other rather than measured once and forgotten. Results come back as timing summaries, with timestamped artifacts written to a `.build-benchmark/` directory.

Use it when you want a baseline, or when you want to compare before and after a change. It fits any moment someone asks how long builds take, how long they should take, or whether builds got faster or slower.

## Questions

### Is Xcode Build Benchmark safe to install?

AIR scanned this exact version of Xcode Build Benchmark and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 6bd7b596cd68, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/xcode-build-benchmark.

### How do I install Xcode Build Benchmark?

Open https://airmarket.ai/app/xcode-build-benchmark on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/avdlee/xcode-build-optimization-agent-skill/tree/6bd7b596cd688b1127ded00e812b1b6937ec35d6/skills/xcode-build-benchmark. Install from that link, not the branch.
