Where Is Xcode DerivedData Stored?
Xcode DerivedData build folder plus Archives and simulators support dirs on Mac.
Last updated
Xcode builds into DerivedData under Developer in Library: per project hashes with build products, indexes and logs. Stale entries there cause famously weird build errors.
Archives (release builds) and simulator data live in sibling folders. Deleting DerivedData only costs rebuild time, never source code.
Where Xcode stores this, by platform
~/Library/Developer/Xcode/DerivedData
Archives under ~/Library/Developer/Xcode/Archives, simulators under ~/Library/Developer/CoreSimulator. Change locations in Xcode Settings, Locations.
Frequently asked questions
Is it safe to delete DerivedData?
Yes. Quit Xcode, delete the folder contents, rebuild. Do a clean build folder from inside Xcode first for lighter cases.
Where are my App Store archives?
Under Archives by date in the same Developer tree. Organizer window opens them; keep those, prune DerivedData instead.
