> I wouldn’t be so pessimistic about macOS or even iOS update rates. According to StatCounter Mojave never went above 52% or market share, which means at its peak 48% of users were still on previous versions.
https://gs.statcounter.com/macos-version-market-share/desktop/worldwide I think it will be worse for Catalina. It's anecdotal, but every Mac user I know will remain in Mojave or even previous macOS versions for the foreseeable future. Also, every audio software developer I know has been sending emails to its users to not update to Catalina. Audio forums are full of people not being able to use their hardware with Catalina because of some driver problem or something else. > Cocoa being deprecated: I think you have some time. Probably, but my point is actually about not being able to plan for the future. Nobody can say for certain if or when Cocoa will be deprecated, in consequence investing a year or two of dev time in a new Cocoa project seems very risky. OTOH investing in a SwiftUI project for macOS is also a bad idea right now unless one is ready to be an early adopter.
