Yes, all the M1 Macs support RealityKit Object Capture. From the page you linked to, the requirements are: at least 4 GB of RAM a GPU which supports ray tracing As a double-check, I ran the tests on that page, on my MacBook Pro, which also uses an M1. All tests passed.

"padding()" should be ".padding()" As in: struct ContentView: View { var body: some View { VStack { Text("Hello, world!") .padding() Text("Another Line") } } } "padding()" is an instance method, so calling it without the leading ".", as you do, probably causes something horrible to happen, which causes the crash. (Since it will return a function, not a View)

Was that helpful, @13774259911?

Was that helpful, @modern?

Do you have a question?

Upload an early build to the App Store. Submitting to TestFlight should make sure (but may not be required).

I reported the upside-down text issue here: https://developer.apple.com/forums/thread/691718 I filed a feedback, ref: FB9684421 I haven't had a response from Apple. The original problem was random, and has not happened (for me) on the latest Xcode (13.2.1)

I suggest you post your "ContentView" code, then it may be possible to say why it doesn't preview.

my goal is to change the text "hello" to number 1 when I click on it Your code is a long way from achieving that. It may be best to work through some tutorials first? Are you studying anything, at the moment? (There is no point my just writing the solution for you, as I think your current code demonstrates a number of misunderstandings.)

While it might be technically possible, it might not be wise. Could you be sure that the app would work correctly/reliably on 12.x, without actually ever running it on 12.x? It would be a bit like developing an iOS app using only the Simulator, but not an actual device. Possible(?), but not advisable.

Typically, you would use a Notification. When the user responds to the notification, that can launch your app, and trigger an action. (Note though, it is also possible for the user to dismiss the notification, and not launch your app.) Other techniques (than Notification) might be possible, but as I understand it, Notification is the only "legal" one, and any other method would risk App Store rejection.

No minimum, you can set whatever you like.

I think you will need to share the code to ArticleRow, for anyone to be able to help you with this.

It might be worth re-creating a new nib file, using Xcode 13?
