xcode-build-benchmark

See your Xcode build baseline before optimizing.

build performance

What it does

Benchmarks Xcode clean and incremental builds and saves repeatable timing summaries and timestamped artifacts.

When to use it

Use when establishing a build-time baseline, comparing changes, or determining whether Xcode builds became faster or slower.

Give it an Xcode project and scheme; it benchmarks build types, saves artifacts in the project, and reports timing summaries.
