GitHub Actions macOS Runner No Space Left

When a macOS CI job fails with `No space left on device`, the fix should be a repeatable runner policy, not a random cleanup command pasted into every workflow.

Free browser cleanup

Find the biggest storage culprit first.

Run the Chrome or Edge web scan, delete one approved low-risk item free, then use the $29 Deep Cleanup only if meaningful space remains.

Common high-risk sources

Xcode DerivedData, ModuleCache.noindex, and build intermediates
Unused simulator runtimes, unavailable devices, and DeviceSupport folders
Homebrew, npm, pnpm, CocoaPods, SwiftPM, Gradle, and toolchain caches
Large test artifacts, screenshots, videos, archives, and logs

Safer CI cleanup order

Print disk usage before cleanup so failures are diagnosable.
Remove workflow-local build output and dependency caches with the owning tool first.
Clean Xcode DerivedData and ModuleCache only after the job no longer needs those artifacts.
Review simulator runtime deletion separately; deleting the wrong runtime can break later jobs.
Print disk usage after cleanup and keep the numbers in the build log.

Starter commands

df -h
du -sh ~/Library/Developer/Xcode/DerivedData 2>/dev/null || true
du -sh ~/Library/Developer/CoreSimulator 2>/dev/null || true
du -sh ~/Library/Caches 2>/dev/null || true
xcrun simctl delete unavailable || true

Turn this into a team runner policy

The $29 Deep Cleanup reviews one representative scan or CI log and returns a safe/review/do-not-touch cleanup plan for your macOS build environment.
