@Developer Tools Engineer thanks for reply. Yes, my widget is fully macOS one (source code https://github.com/bobrosoft/macos-yandex-weather-widget). So, SwiftUI previews are not working for macOS Widgets anymore in Ventura? I tried to run older Xcode 13.4 on Ventura -- seems previews not working as well, seems as issue is in macOS. I checked the link you posted but didn't get it clearly what to do now: you suggest to add iOS as target to see previews or debug things only manually? Thanks.
