This isn’t something that is specific to Vision Pro, but it is an xCode feature that is awesome, if you select some code and press { it will wrap the selected code with { and }.
Should look into xCode shortcuts they are internal snippets.
SwiftData seems very simple to implement. Wish it had sync with the server and cross platform support!
Well I’ve finished the playlist I found last night for this. So now I have a Todo List app that will only work on Vision Pro. For now I’m not going to try and add more features to that. If I want to build a Todo List app in the future it will have to support MacOS, iPhone, iPad and Android; not just Vision Pro.
