SwiftUI support

[AccuPhoenix01]

SwiftUI doesn't treat UIFonts like its own SwiftUI Font class, so by default using the same paradigm of the pod doesn't work. Would be great to have baked-in SUI support that can use the same syntax as before.

BTW, I love Swash and has made it easy to use in new AccuWeather app. 🤩

this might be as easy as:
let swashFont = Solis.black.of(size: 18) as CTFont

then

Text("words")
  .font(Font(swashFont))

and really not require any change.
