xcode documentation

I'm doing a bit of hard-drive spring-cleaning. I have just under 6G of developer documentation under ~/Library/Developer/Shared/Documentation/DocSets with dates from 2013 - 2015. Is this likely to be obsolete for Xcode (I'm still running Xcode 12.4) and can I delete these files?
