What Hacker News says

2 sources
The documentation of SwiftUI is poor but I was able to create mostly what I wanted from it, this was a year or so ago. I released a SwiftUI calculator I built earlier as open source on GitHub, it may be useful for some dipping their toes into it. I actually really enjoyed working in SwiftUI. Towards the end of my time, I started moving into a hybrid approach where I would borrow some of the concepts of CSS stylesheets and clearly separate constant parameters used in UX into their own swift files (making it easier to flip between them, eg when going from light mode to dark or from iPhone to iPad) Link: https://github.com/ashok-khanna/RPN-31
