Most of these negative comments are coming from veteran UIKit developers who then tried out SwiftUI. Of course they're only going to notice the things that are overwhelmingly harder compared to UIKit - they have years of bias. Imagine if SwiftUI came out first, then Apple released UIKit. Wouldn't there be another long complaint list from these developers?

I started developing with UIKit for a year, hated it, then switched to SwiftUI and have built multiple apps over the past few years. IMO the "last 10%" bugs are not that big of a detractor compared to the benefits. Of course some of this is my bias; I'm more likely to spend time trying Stack Overflow hacks on SwiftUI bugs when the UIKit solution is better. I have to "work with the grain" sometimes if something just isn't possible in SwiftUI, but I'm fine making that tradeoff. I feel lucky not having the bias of years of UIKit, it's hard to let go of something when you're so used to it. I'm also lucky to not be working on apps with backwards compatibility issues, but I do think SwiftUI is the way to go for new consumer startups.
