Thanks! I reviewed the options, and I was wondering which run destination (not target, sorry) will be used when choosing the Xcode option. I was worried about an issue I had with a SwiftUI NavigationSplitView in Mac Catalyst (FB12108868), but I found a workaround and I don't think I'll have any specific instructions.

Make sure to check if your app builds and runs on Swift Playgrounds.

NavigationView is deprecated. You can use NavigationStack and NavigationSplitView instead. Here you can find more details.
