Context: I’ve been working with iOS full time since a few years before Swift came out. A few startups ago we built our app using SwiftUI 1.0. At that time, while 90% of it was fantastic, 10% was either unworkable or extremely unreliable, causing for some maddening bugs. The documentation was laughable so for these reasons I chose to do the app for a subsequent startup in UIKit. Fast forward to my most recent company;…

Do you mind explaining exactly what animations would take that much work? I’m struggling to see how animations could ever take as long as estimated for UIKit

If you like SwiftUI, I challenge you to a SwiftUI fizzbuzz: a square, screen width, 10x padding, red background. inside it, a little square, centered and a little square, top left corner, 10px padding, blue background for both. Tell me that was easy, so that I know you're lying :)

  struct ContentView: View {
      var body: some View {
          ZStack {
              Rectangle()
                  .fill(Color.red)
              Rectangle()
                  .fill(Color.blue)
                  .frame(width: 100, height: 100)
              HStack {
                  VStack {
                      Rectangle()
                          .fill(Color.blue)
                          .frame(width: 100, height: 100)
                      Spacer()
                  }
                  Spacer()
              }
              .padding(10)
          }
          .aspectRatio(1, contentMode: .fit)
          .padding(10)
      }
  }

...no comparison with Flutter or at least remarks of what would also apply to it?

Flutter is almost exclusively used by web developers in my professional and personal experience which is odd considering the lack of JS. The types of companies that hire iOS developers and build iOS apps also hire android developers and build android apps, again, IME.

Is anyone using this really? My team is pretty excited about using it but I've been a little more hesitant mostly because I've not read of anyone using it at any sort of scale with success. Even for smaller project it still doesn't seem production ready.

I just finished a contract on an app with 400K users. It was in pretty bad shape when I got my hands on it. Last update: February 2020. Targeting iOS 11+, mostly UIKit, powered by Cocoapods with 25 dependencies, and 1.3M LOC. It took me 3 months to rewrite everything from scratch in SwiftUI, with 100% feature parity. Of the ~20 different view/components that I had to write, just one required me to dip into UIKit (wit…
