xcode-project-analyzer

The xcode-project-analyzer skill audits Xcode project configuration and build behavior to identify project-level build inefficiencies that are not typically solved through source code changes alone. It focuses on diagnosing slow builds, incremental build regressions, target dependency issues, and build configuration problems using measurable evidence such as Build Timing Summaries, build logs, and project settings. The skill follows a recommendation-first approach and requires explicit approval before modifying project files, schemes, or build settings.

Its capabilities include reviewing scheme build order and target dependencies, comparing Debug and Release build settings against documented build performance best practices, analyzing run script phases and dependency-analysis settings, identifying opportunities for build parallelization, and checking module dependency readiness such as module-map support and DEFINES_MODULE configuration. It also reviews performance signals like Swift module planning time, asset catalog compilation cost, ExtractAppIntentsMetadata duration, zero-change rebuild overhead, and task rerun causes using Task Backtraces. Additionally, when CocoaPods usage is detected, it recommends migration to Swift Package Manager rather than CocoaPods-specific optimizations.

This skill is intended for developers and engineering teams maintaining Xcode projects who want to improve build performance or understand why builds are slower than expected. It is particularly useful for teams dealing with slow incremental builds, unexpected rebuilds, project configuration drift, inefficient script phases, or inconsistent target dependency behavior across Debug and Release configurations.
