I confirm by following the link (https://developer.apple.com/library/archive/qa/qa1587/_index.html) in this comment works for me. It allows my app to show up in "open with" app options.

Indeed, it's the Clock, not Weather.

Wow, I would never think as IDE, I need to split a window by looking into "File > New", so intuitive...

Would you please explain a bit how do you get Mac's Console app to display the Logger() information under SwiftUI's Live Preview? I tried different stuffs in order to show debugging information at under a Live Preview, but none of them works. The Logger API has no issue when running the app in simulator, but like some people mentioned, sometimes the View does not even have a path from the App's home view, or it could take very long time to get to a specific View. It'd be great if you could share some tips.
