How to get Documentation and API Reference files

Apple API Reference and Documentation is available offline in Xcode.


I am developing an API Documenation Browser and need to know how to get access to the docset files (e.g. the offline documentation for nstablview like on the following link: https://developer.apple.com/documentation/appkit/nstableview)


I know how to get docsets for Guides and Samples but not how to get Swift and API Documentation.


Thanks in advance and best regards,


Sandro
