Native in terms of binary code and workable API.

But not native in terms of a great design interpretation of the Mac OS HIG (Human Interface Guidelines), or in terms of an API use that maps well to the Mac HIG. e.g. I can't see many Catalyst apps becoming Apple Design Award winners without significant design rework.

I did some Catalyst conversions of a few of my iOS apps, for quick and dirty demos and some laughs. But then decided to redesign and rewrite the UI of the apps for AppKit instead of UIKit to create a better user experience and a more attractive app on a MacBook.

I do agree that, UI-wise, Catalyst needs some work. It could make the app look/function a lot better on the Mac...

However, performance-wise, they're pretty quick. Swift Playgrounds runs reeeeeeeeealy fast on my Mac.
 
This is fantastic news! It's surprising what you can build with Swift and SwiftUI. It's a pretty powerful environment to build apps just for my personal use without having to pay for a yearly developer subscription.
 
I started my adveture with Swift Playgrounds last Sunday mainly because of #stayhome. First on an iPad Mini, then on iPad Pro 12.9. Yesterday I tried on my late 2013 i7 MBP, but the fans were turning like crazy. So I tried another setup:
iPad Pro 12.9 with a HDMI monitor, USB keyboard and USB mouse connected all via USB-C dongle. It seems to work :) > I will spend more time with it later today, but my first impression is good.

Interesting approach. I could do this with my iPad Air3 using AirPlay to the TV and using an Apple Bluetooth Keyboard.
