Xcode Compilation Analyzer Use this skill when compile time, not just general project configuration, looks like the bottleneck. Core Rules Start from evidence, ideally a recent .build-benchmark/ artifact or raw timing-summary output. Prefer analysis-only compiler flags over persistent project edits during investigation. Rank findings by expected wall-clock impact, not cumulative compile-time impact. When compile tasks are heavily parallelized (sum of compile categories >> wall-clock median), note that fixing individual hotspots may improve parallel efficiency without reducing build wait time. When the evidence points to parallelized work rather than serial bottlenecks, label recommendations as "Reduces compiler workload (parallel)" rather than "Reduces build time." Do not edit source or build settings without explicit developer approval.
