There are a large number of macOS users that are not app software devs. There's a large base of creative users that couldn't code their way out of a wet paper bag, yet spend lots of money on Mac hardware.

I’m among them, even if creative works aren’t my bread and butter (I’m a dev with a bit of an artistic bent).
That said, attracting creative users also adds value to the platform by creating demand for creative software for macOS, which keeps existing packages for macOS maintained and brings new ones on board every so often.
I'm a mix of both, however, my dev time does not create macOS or iDevice apps. My dev is still focused on creative/media workflows, while I still get work for photo/video. I don't even use Xcode any further than running the CLI command to install the necessary tools to have CLI be useful.
