First apologies because I clearly messed up when sending. So can you re-ask 
your question on the version of this thread that isn't [DRAFT] followed by 
blank?

Second, I do not anticipate deprecating osx because Swift will/can be deployed 
to OS X as well as macOS. I'll answer on the other thread too, so there's a 
clear record of discussion for archival retrieval.

Thanks (and sorry),
