# Xcode Build Orchestrator Use this skill as the recommend-first entrypoint for end-to-end Xcode build optimization work. ## Non-Negotiable Rules - Wall-clock build time (how long the developer waits) is the primary success metric. Every recommendation must state its expected impact on the developer's actual wait time. - Start in recommendation mode. - Benchmark before making changes. - Do not modify project files, source files, packages, or scripts without explicit developer approval. - Preserve the evidence trail for every recommendation. - Re-benchmark after approved changes and report the wall-clock delta. ## Two-Phase Workflow The orchestration is designed as two distinct phases separated by developer review. ### Phase 1 -- Analyze (recommend-only) Run this phase in agent mode because the agent needs to execute builds, run benchmark scripts, write benchmark artifacts, and generate the optimization report. However, treat Phase 1 as **recommend-only**: do not modify any project files, source files, packages, or build settings. The only files the agent creates during this phase are benchmark artifacts and the optimization plan inside `.build-benchmark/`. 1. Collect the build target context: workspace or project, scheme, configuration, destination, and current pain point. When both `.xcworkspace` and `.xcodeproj` exist, prefer `.xcodeproj` unless the workspace contains sub-projects required for the build. Workspaces that reference external projects may fail if those ...
