Can I Delete Xcode DerivedData?

Usually, yes. DerivedData contains build output, indexes, and intermediate files that Xcode can regenerate.

Safe answer

Close Xcode first. Then deleting DerivedData is generally safe, though the next build may take longer because Xcode has to recreate cache and indexes.

What it does not delete

• Your source code
• Your project files
• Your App Store account
• Your installed Xcode app

Read-only check

du -sh ~/Library/Developer/Xcode/DerivedData
