Hi darkpaw,
Yes, I have tried both of those suggestions from Xcode.
For the first, the error shown is "Closure containing control flow statement cannot be used with result builder 'AppShortcutsBuilder'". Ive also tried to remove the @AppShortcutsBuilder property wrapper and the same error is still shown.
For the second, a build error says you cannot have two structs conforming to AppShortcutsProvider in a project.
