SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Systematically identify and reduce slow Xcode build times by measuring baseline performance, analyzing the Build Timeline, and applying targeted optimizations.

Core Features & Use Cases

  • Build timing measurement and baseline creation
  • Build Timeline analysis and critical path diagnosis
  • Bottleneck discovery with stepwise optimization patterns
  • Guidance for enabling compilation caching, parallelization, and incremental builds
  • Real-world workflow examples across iOS/macOS projects

Quick Start

Start by running a baseline clean build, then apply one optimization at a time and measure the impact to validate improvements.

Frequently Asked Questions about axiom-build-performance

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I identify bottlenecks in slow Xcode build times?▼

Identify slow Xcode build bottlenecks by measuring a baseline clean build and analyzing the Build Timeline to diagnose the critical path. This process pinpoints specific compilation delays across iOS and macOS projects.

What is the best way to speed up Xcode builds for iOS and macOS projects?▼

The best way to speed up Xcode builds is applying proven workflows for incremental builds, compilation caching, and parallelization. Measure each optimization stepwise to validate performance improvements.

How does analyzing the Build Timeline improve Swift compilation performance?▼

Analyzing the Build Timeline improves Swift compilation performance by diagnosing the critical path and exposing specific bottlenecks. This allows you to apply targeted optimizations for faster, more deterministic builds.

Can I use compilation caching and parallelization for CLI projects in Xcode?▼

Yes, you can apply compilation caching and parallelization workflows across CLI, iOS, and macOS projects. These optimizations reduce build times by enabling faster, more deterministic compilation.

Why should I measure a baseline clean build before optimizing Xcode build performance?▼

Measuring a baseline clean build establishes a performance starting point so you can validate the impact of each optimization. Apply changes stepwise and measure again to ensure faster, deterministic builds.
