Is it safe to delete a DerivedData folder in a project?

Rebuilds automatically Yes.

Build products kept inside the project. Xcode rebuilds them on the next build.

You can remove it while Xcode is open. ClearMac reminds you first, in case a build is running.

Where it is

• folders named DerivedData

What “Rebuilds automatically” means

The app or tool that made it recreates it by itself the next time it's needed. Removing it only costs a little time. ClearMac pre-selects these items.

How ClearMac handles it

ClearMac pre-selects it in a cleanup and moves it to the Trash, so you can put it back until you empty the Trash.

This page is generated from the same rule ClearMac uses on your Mac (project.derived-data), so the app and this page always say the same thing.
