Paulo Andrade: ‘A WWDC 27 Update on Building a Mac-Assed App With SwiftUI’

Paulo Andrade:

My last post on using SwiftUI to build a Mac-assed app got a bit more traction than I expected. It was mentioned on Mastodon several times, included in iOS Dev Weekly, inspired May’s edition of the Swift Blog Carnival, and was eventually mentioned by John Gruber, arguably the person most to blame for popularizing the term “Mac-assed”, on Daring Fireball.

All this attention also resulted in an engineer from Apple reaching out with some notes. We exchanged a few emails, I filed a few radars, and now that WWDC 27 is behind us, this post serves as a small update to the issues I wrote about before.

There’s real progress here, but I think my main point still stands: SwiftUI is now seven years old and it does not make it easy to create great Mac apps.
