Thanks! I personally dislike Electron apps but I understand the appeal of it which explains why many desktop apps are written with it.

It is not easy developing a well-crafted macOS app compared to iOS development as resources are limited. The obvious place is reading the AppKit documentation and the Human Interface Guidelines. Apple has some tutorials on their website using SwiftUI and Catalyst.

Ray Wenderlich and Hacking with Swift website has a book on macOS development.

If you do write a macOS app, do let me know, I look forward to it!
