After going through and cleaning my disk with old things that I didn’t need anymore, I came across the iOS DeviceSupport folder in ~/Library/Developer/Xcode which was taking nearly 20 GB.
A similar question has been asked before, but since then many things have changed and I would like an up-to-date answer.
As long as I have the version I use for testing, can I delete the older/unused versions without breaking anything?
