xcode-compilation-analyzer SKILL.md skillA
xcode-compilation-analyzer from jordancoin/ios-skills-collection is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jordancoin/ios-skills-collection/xcode-compilation-analyzer@git:20260329.893209fPins git:20260329.893209f in mdr.lock. Pin the fingerprint instead.

Analyze Swift and mixed-language compile hotspots using build timing summaries and Swift frontend diagnostics, then produce a recommend-first source-level optimization plan. Use when a developer reports slow compilation, type-checking warnings, expensive clean-build compile phases, long CompileSwiftSources tasks, warn-long-function-bodies output, or wants to speed up Swift type checking.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. ## What To Inspect - `Build Timing Summary` output from clean and incremental builds - long-running `CompileSwiftSources` or per-file compilation tasks - `SwiftEmitModule` time -- can reach 60s+ after a single-line change in large modules; if it dominates incremental builds, the module is likely too large or macro-heavy …

How to install
mdr add jordancoin/ios-skills-collection/xcode-compilation-analyzer@sha256:c49d8bf206d6ea2dThe line at the top of this page pins the label git:20260329.893209f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
