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? % ls -l total 0 drwxr-xr-x 3 peterhull 501 96 19 Sep 2013 Library drwxr-xr-x 3 peterhull 501 96 10 Aug 2013 com.apple.ADC_Reference_Library.DeveloperTools.4_6.docset drwxr-xr-x 3 peterhull 501 96 10 Aug 2013 com.apple.adc.documentation.AppleOSX10_8.CoreReference.docset drwxr-xr-x 3 peterhull 501 96 10 Aug 2013 com.apple.adc.documentation.AppleiOS6.1.iOSLibrary.docset drwxr-xr-x 3 peterhull staff 96 6 Mar 2015 com.apple.adc.documentation.OSX.docset drwxr-xr-x 3 peterhull staff 96 8 Apr 2015 com.apple.adc.documentation.Xcode.docset drwxr-xr-x 3 peterhull staff 96 8 Apr 2015 com.apple.adc.documentation.iOS.docset drwxr-xr-x 3 peterhull staff 96 20 Sep 2015 com.apple.adc.documentation.watchOS.docset
