How do I get documentation of mac OS X 10.15 APIs

Hi,

I have an early 2013 MacBook pro and I need to write some software on it but all the documentation I can find for the APIs are for newer versions. How do I access the versions appropriate to the latest supported OS X (10.15)?

Thanks, James

appropriate to the latest supported OS X (10.15)?

If you open Xcode 12.4, API references there should correspond to 10.15. And not show newer versions of API.
