Is SwiftUI a buggy?

SwiftUI is buggy, immature and undocumented . But it also looks like Apple’s future focus. If you are starting a new app today, you’re pretty much betting that Apple will improve SwiftUI’s features as soon as you’ll need them. Again, as we said, it’s about tradeoffs rather than right and wrong.

In short, SwiftUI is a wonderful and very promising framework. I think it’s the future . But, it could be another 3–5 years until it reaches the same reliability and robustness as UIKit. However, that doesn’t mean you shouldn’t use SwiftUI today.
