Both Jetpack Compose and SwiftUI came out around the same time, in 2019 I think.

It's probably more correct to say that both frameworks copied React Native and made it more "native"

... and React Native copied the declarative approach of React, which copied WPF, which copied ... (no, we're definitely not the first ones to do declarative UIs here in 2023).

oh, its from wpf maybe thats why gearon interest in react that much because he have c# background

React definitely did not copy WPF. It copied XHP: https://docs.hhvm.com/hack/XHP/introduction which was another Facebook thing, but that itself was inspired by E4X: https://en.m.wikipedia.org/wiki/ECMAScript_for_XML
