Your code does not compile, as you have not defined "Number" The actual error is "Cannot find 'Number' in scope".

Did you try clearing the contents of the Derived Data folder? Product > Clean Build Folder Or the more drastic version Quit Xcode Delete the contents of the "Derived Data" folder Run the app again

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

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

No minimum, you can set whatever you like.

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.

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.

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.)

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

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)

File > New > Project macOS > Command Line Tool Language: Objective-C or File > New > Project macOS > App Interface: Storyboard ( or XIB, but if you choose SwiftUI, language must be "Swift") Language: Objective-C

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

Do you have a question?
