The fact that Apple's developer tooling is described as great makes me suspicious if the author has used JS tooling in a serious way. VS Code is just so much better than XCode. My experience developing native apps in SwiftUI is also that the documentation is very very lacking. And lastly I wasn't able to get a hover effect without dropping tons of frames. My lack of experience I'm sure is partly to blame for the app's poor performance, but it certainly wasn't performant out of the box. React would have been significantly more performant for my use case.
