What problem does it solve?

This Skill addresses the common frustration of slow Xcode build times, which significantly hinder developer productivity. It provides a systematic approach to analyze, identify, and optimize bottlenecks in compilation, linking, and script phases.

Core Features & Use Cases

  • Systematic Optimization Workflow: Guides through measuring baselines, analyzing the Xcode Build Timeline, and identifying critical path bottlenecks.
  • Targeted Optimization Patterns: Provides specific fixes for slow Swift type checking, inefficient build phase scripts, and suboptimal compilation mode settings.
  • Parallelization Strategies: Leverages Xcode's parallel build capabilities and dependency management to shorten the critical path and maximize core utilization.
  • Use Case: When your incremental debug builds are taking too long, use this skill to ensure "Build Active Architecture Only" is set to YES and "Compilation Mode" is "Incremental" for Debug configurations, drastically reducing build times.

Quick Start

To measure your clean build time, run time xcodebuild build -scheme YourScheme in your terminal, then record the total duration.
