SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses slow Xcode build times by providing systematic analysis and optimization strategies for compilation, linking, and scripting phases.

Core Features & Use Cases

  • Build Timeline Analysis: Identify critical path bottlenecks and idle core time.
  • Performance Tuning: Optimize compilation modes, active architecture settings, and debug information formats.
  • Advanced Xcode Features: Leverage compilation caching (Xcode 26+) and explicitly built modules (Xcode 16+) for significant speedups.
  • Use Case: Reduce your project's clean build time from 5 minutes to under 2 minutes by applying targeted optimizations for compilation and parallelization.

Quick Start

Run the /axiom:optimize-build agent for automated scanning and quick wins.

Frequently Asked Questions about axiom-build-performance

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

FAQPage Schema
How do I optimize Xcode build times for slow Swift compilation?▼

Optimize Xcode build times by analyzing build timelines to identify compilation and linking bottlenecks, then applying compilation caching and explicitly built modules to reduce slow incremental builds.

What's the best way to reduce slow incremental builds in iOS projects?▼

Reduce slow incremental builds by tuning active architecture settings and debug information formats, while leveraging explicitly built modules in Xcode 16+ to improve parallelization and address idle core time.

Do I need Xcode 26 to use compilation caching for build performance?▼

Yes, you need Xcode 26+ for compilation caching to achieve significant speedups. Build timeline analysis requires Xcode 14+, while explicitly built modules are available starting with Xcode 16+.

How does build timeline analysis identify compilation bottlenecks?▼

Build timeline analysis identifies compilation bottlenecks by mapping the critical path and detecting idle core time during the build process, allowing targeted performance tuning across iOS and macOS platforms.

Can I improve parallelization for macOS and iOS Xcode builds?▼

You can improve Xcode parallelization by adjusting compilation modes and applying explicitly built modules, which addresses inefficient core utilization across Apple platforms including iOS and macOS.
