Fix for missing documentation indexes and other anomolies in the Xcode documentation viewer. Mine seemed to get all borked up with some beta relaeases. Shamelessly ripped off from this thread.
- Quit Xcode
- Delete the cache file at
~/Library/Caches/com.apple.dt.Xcode
. - Delete the contents of
~/Library/Developer/Shared/Documentation/DocSets/
. - Delete the contents of
/Applications/Xcode.app/Contents/Developer/Documentation/DocSets/
. - Launch Xcode.
- Open the Preferences pane, select the Downloads tab, and download the docsets you want to use.
These instructions are outdated and yet they still helped me! Thank you for solving my issue
