My SwiftUI codebase for https://equater.app definitely has some "// TODO: when apple fixes X" comments, but there's no denying the MASSIVE developer velocity I gained from using the framework.
If the bugs are bad enough I can always do something custom in UIKit via UIViewRepresentable.
I wonder what the economics of this product look like at $9.99/month. I'm rooting for them. I think the vast majority of people that would pay for premium software can't justify paying more for email than they pay for JetBrains, Adobe, or Figma/Sketch.
I've seen the happy customers paying $30. I just wonder if they're missing out on 5-10 more happy customers for every 1 of those that's willing to pay $9.99.
I love the emacs philosophy. Doom emacs with evil mode is a gorgeous experience. However, once LSP and a few plugins are running it's just too slow to use. I hope one day we'll have a multi-threaded version of emacs that can compete with VSCode, JetBrains, and Xcode.
