Xcode Build Benchmark

Use this skill to produce a repeatable Xcode build baseline before anyone tries to optimize build times.

Core Rules

• Measure before recommending changes.
• Capture clean and incremental builds separately.
• Keep the command, destination, configuration, scheme, and warm-up rules consistent across runs.
• Write a timestamped JSON artifact to .build-benchmark/.
• Do not change project files as part of benchmarking.
