@jeffmueller That's how I think about it too. Something is better than nothing, and there is usually room to iterate and improve the parts that need more Mac-like attention.
@manton @jeffmueller Fairly obvious upside: these apps will ease people into the new ideas that iOS will truly bring to the Mac (i.e. innovation in third-party work), whilst Swift UI gradually gets ready for mainstream use. By the time the latter happens, the former will have laid the groundwork for a smoother transition as compared to without any of this "in-between state" work.
