Link: Catalyst vs SwiftUI: Which is better for building a new Mac/iPad app?
Unfortunately the thing SwiftUI does share with Swift 1.0 is that it’s very much a beta technology that is in no way ready for extensive use. … The bigger problem though are the tools and documentation. Compiler errors are useless to the point that it would almost be better that they weren’t shown.
Looks like we might still have a ways to go.
