Xcode DerivedData No Space Left

Xcode `No space left on device` errors often point at DerivedData or ModuleCache, but the safest fix is to separate rebuildable cache from archives, simulator runtimes, and project state.

SafeDisk Lite local scan

Download the Mac app and scan in this same page.

The website alone cannot read Mac folders. SafeDisk Lite adds the local permission bridge, then this web UI shows the largest visible buckets and one optional cleanup candidate.

Usually safer to clean

DerivedData after Xcode and xcodebuild jobs are stopped
ModuleCache.noindex when the build can regenerate modules
Old build logs and temporary intermediates after preserving failure logs you need

Review before deleting

Archives used for releases, crash symbolication, or App Store history
Simulator runtimes required by active projects or CI matrix jobs
DeviceSupport folders for devices still used by QA or release testing

Read-only checks first

du -sh ~/Library/Developer/Xcode/DerivedData
du -sh ~/Library/Developer/Xcode/Archives
du -sh ~/Library/Developer/CoreSimulator
du -sh ~/Library/Developer/Xcode/iOS\ DeviceSupport 2>/dev/null

Need this as a repeatable team rule?

SafeDisk turns one representative Xcode scan into a safe/review/do-not-touch cleanup plan for developers, QA automation, or macOS CI runners.

Deep Cleanup

Still full after the SafeDisk Lite scan?

Start with the SafeDisk Lite scan. If the scan shows review-first storage that still needs judgment, send one request for the $29 Deep Cleanup next step.
