Showing multiple previews in Xcode 15 and up using Preview Macro

Question

How can I show two or more different variants in Xcode using the new #Preview macro?

Without the macro, this was possible:

struct TutorialView_Previews: PreviewProvider {
 static var previews: some View {
 MyAwesomeView(title: "Title One", hideSomePart: true)
 .previewDisplayName("Hidden some part")
 
 MyAwesomeView(title: "Title Two", hideSomePart: false)
 .previewDisplayName("Showing all parts")
 }
}

But with the new macro, this isn't compiling:

#Preview {
 MyAwesomeView(title: "Title One", hideSomePart: true)
 .previewDisplayName("Hidden some part")
 
 MyAwesomeView(title: "Title Two", hideSomePart: false)
 .previewDisplayName("Showing all parts")
}

Answer 1

Using .previewDisplayName("...") does not work for me. I got it working doing it like this:

#Preview("Hidden some part") {
 MyAwesomeView(title: "Title One", hideSomePart: true)
}
#Preview("Showing all parts") { 
 MyAwesomeView(title: "Title Two", hideSomePart: false)
}

• Jorn Rigter: See previewDisplayName documentation -- should work on iOS 13.0+
• D'Fontalland: It should but I didn't. They way I got it working was as I showed on my example.

Answer 2

Turned out to be a simple fix:

#Preview {
 MyAwesomeView(title: "Title One", hideSomePart: true)
 .previewDisplayName("Hidden some part")
}
#Preview { 
 MyAwesomeView(title: "Title Two", hideSomePart: false)
 .previewDisplayName("Showing all parts")
}

• kakaiikaka: previewDisplayName not work on Xcode 15, Use #Preview("PreviewName") like D'Fontalland said.
• Jorn Rigter: Thanks for the heads up! I've accepted their answer as the accepted answer, then it seems like the documentation is wrong about how to show the preview display name
• kakaiikaka: they only work if you are not using the new Preview Marco syntax.

Yea if you try using .previewDisplayName in a #Preview macros nowadays it shows a warning - 1. PreviewDisplayName is ignored in a #Preview macro. Provide the name to the macro initializer, e.g. #Preview("preview name")

You should just use "#Preview("your preview name")"
