I'm trying to work on editing grids sample app in playgrounds. It works fine on my iPad but it is not working on my Mac. I can see the code but I get an error message that minimum deployment target is 16 and there is no preview showing. MacOS is up to 13 no? So I guess it is refering to iPad OS 16? How do I fix this on my Mac? Also the code references NavigationStack which now replaced NavigationView but in Xcode it doesn't show up in autocomplete and the compiler doesn't recognize it. When I go into apple store both xcode and playground just say "open", there is no update option. What do I do?
