SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This skill addresses slow compilation times, excessive type-checking warnings, and long build phases in Swift and mixed-language projects by identifying specific code-level and configuration bottlenecks.

Core Features & Use Cases

  • Diagnostic Analysis: Parses build timing summaries and compiler diagnostics to rank the most expensive functions and expressions.
  • Optimization Planning: Provides actionable, evidence-based recommendations to reduce compiler workload and improve parallel build efficiency.
  • Use Case: When a developer faces long CompileSwiftSources tasks or slow incremental builds, this skill analyzes the build logs to pinpoint whether the issue stems from complex type-checking, monolithic modules, or inefficient bridging headers.

Quick Start

Use the xcode-compilation-analyzer skill to diagnose the current project by running the compilation diagnostics script with a 100ms threshold.

FAQPage Schema
How do I diagnose slow Swift compilation times in Xcode?

To diagnose slow Swift compilation, parse build timing summaries and compiler diagnostics to rank the most expensive functions. This identifies bottlenecks in type-checking and module emission to generate source-level optimization plans.

Why does my Xcode incremental build take so long?

Long incremental builds often stem from complex type-checking, monolithic modules, or inefficient bridging headers. Analyzing build logs pinpoints these specific code-level bottlenecks to reduce overall compiler workload.

What is the best way to optimize Xcode build performance?

The best way to optimize Xcode build performance is analyzing compilation hotspots to generate evidence-based recommendations. This reduces compiler workload and improves parallel build efficiency for slow clean builds.

Do I need xcodebuild command-line tools to analyze compilation hotspots?

Yes, analyzing compilation hotspots requires xcodebuild command-line tools and access to project build logs or timing summaries. These inputs perform root-cause analysis for excessive type-checking durations.

Can this analyzer handle mixed-language compilation bottlenecks?

Yes, it handles mixed-language compilation bottlenecks by analyzing slow CompileSwiftSources tasks and inefficient bridging headers. It provides project-level optimization plans for mixed-language projects experiencing long build phases.
