SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This skill eliminates guesswork in build performance optimization by providing a standardized, repeatable method to measure clean and incremental build times.

Core Features & Use Cases

Standardized Benchmarking: Captures clean, cached-clean, and zero-change build metrics to establish a reliable performance baseline.
Artifact Generation: Produces timestamped JSON reports and raw logs, enabling data-driven comparisons before and after project changes.
Use Case: Use this skill when you need to verify if a recent architectural change improved build times or to diagnose why a specific project scheme is performing poorly during incremental development.

Quick Start

Run the xcode-build-benchmark skill by providing the workspace path and scheme to generate a performance report for your current project configuration.

FAQPage Schema

How do I measure Xcode build performance for clean and incremental builds?▼

Measuring Xcode build performance involves benchmarking clean, cached-clean, and incremental build durations via the xcodebuild command-line tool. This generates structured JSON artifacts containing timing summaries and environment metadata for reliable comparison.

What is the best way to establish a reliable Xcode build time baseline?▼

Establishing a reliable Xcode build time baseline requires capturing clean, cached-clean, and zero-change build metrics. This standardized benchmarking method eliminates guesswork by producing timestamped JSON reports and raw logs for data-driven comparisons before and after project changes.

Do I need Python to benchmark Xcode build times?▼

Yes, benchmarking Xcode build times requires Python 3 and access to the xcodebuild command-line tool. These prerequisites execute the scripts and parse build timing data to generate performance reports.

How do I diagnose slow incremental build times in my iOS project?▼

Diagnosing slow incremental build times in an iOS project requires benchmarking zero-change and cached-clean build durations. Comparing timestamped JSON artifacts before and after architectural changes reveals why a specific project scheme performs poorly.

Can I benchmark Xcode workspace build performance for a specific scheme?▼

Yes, you can benchmark Xcode workspace build performance for a specific scheme by providing the workspace path. The benchmark operates on Xcode projects or workspaces to generate a performance report for your current configuration.

When do I need to generate timestamped JSON reports for Xcode builds?▼

You need to generate timestamped JSON reports for Xcode builds when verifying if a recent architectural change improved build times. These structured artifacts contain timing summaries and environment metadata, enabling data-driven comparisons to track performance regressions.
