What is the com.apple.dt.Xcode bundle, and can I delete it?

In looking to free space on my system volume. I found this file:

~/Library/Caches

The file is over 15GB in size, but I can't really tell what it comprises.

I see a Downloads in there, so perhaps it has the manuals/documentation that I've downloaded? Can I relocate this bundle, or should I leave it alone?

It's safe to delete

com.apple.dt.XCode

because Xcode will recreate its caches when needed (it can take some time at first relaunch, though, if Xcode needs to re-download something).

You should not delete the whole

~/Library/Caches

folder, though, because it contains many applications preferences and it wouldn't be safe to delete everything.

To gain more space, you can also delete the obsolete contents of

~/Library/Developer/Xcode/iOS DeviceSupport/

(for example, the old iOS versions you don't use anymore).

There's also stale Xcode data in

~/Library/Developer/Xcode/DerivedData

that you can remove safely.
