I liked the promise, but the reality has been disappointing.

SwiftUI is great for test harnesses and admin utilities, but I won't use it for shipping software. I have one app that I rewrote in SwiftUI, just so that I can say that I have shipped it, but I am still using UIKit for most of my apps.

I'm not thrilled with UIKit, but SwiftUI has kind of withered on the vine.
