Whilst trying to free up some disk space for a new Virtual Machine, I noticed that I have about 50GB of Xcode related stuff (that's not the app itself)

I'm not sure what is just obsolete and what is actually still used by Xcode (On my Mac I keep Xcode 6.4 and Xcode 7.1)

Here are the two main culprit folders:

~/Library/Developer/Xcode/iOS DeviceSupport (41GB)

This seems to full of symbol files, for many versions of the OS. I am guessing these get created each time a new device/OS pair gets attachched to the Mac and Xcode does its "Copy Symbol files" thing. So is it safe to just delete the contents of this folder and let Xcode re-copy the symbol files as I use devices again.

~/Library/Caches/com.apple.dt.Xcode/Downloads (9GB)

Mostly a variety of disk images for various versions of OS documentation. Am assuming that the documentation itelf is not read off these images once the docset has been installed off it. As such, any harm in deleting them too?

As far as "~/Library/Developer/Xcode/iOS DeviceSupport" is concerned, then yes it does indeed seem that that is where the "Copy Symbol Files" files go. Emptying it did no harm and plugging in devices started to recreate the relevant stuff as needed.

Not tried "~/Library/Caches/com.apple.dt.Xcode/Downloads" yet as emptyhing the other folder freed up enough space for me
