# Xcode Compilation Analyzer

Find the Swift code that's costing you the most compile time

## What this does

Compiling your Swift code takes longer than it should and you don't know which parts are responsible. This uses your build's own timing information and Swift compiler diagnostics to find the expensive spots, then suggests what to change in the source. Reach for it when compilation itself is the slow part.

### Top 3 things it does for you

- Find out which files are slowest to compile
- Chase down type-checking warnings
- Get a plan for speeding up Swift compilation

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Xcode Compilation Analyzer

This analyzes Swift and mixed-language compile hotspots, drawing on build timing summaries and Swift frontend diagnostics, and produces a recommend-first source-level optimization plan.

It fits reports of slow compilation: type-checking warnings, expensive clean-build compile phases, long CompileSwiftSources tasks, or warn-long-function-bodies output. It also covers the plainer version of the same question, wanting Swift type checking to be faster.

## Questions

### Is Xcode Compilation Analyzer safe to install?

AIR scanned this exact version of Xcode Compilation Analyzer and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 6bd7b596cd68, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/xcode-compilation-analyzer.

### How do I install Xcode Compilation Analyzer?

Open https://airmarket.ai/app/xcode-compilation-analyzer on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/avdlee/xcode-build-optimization-agent-skill/tree/6bd7b596cd688b1127ded00e812b1b6937ec35d6/skills/xcode-compilation-analyzer. Install from that link, not the branch.
