I wanna add an intents app extension on iOS 15, I'm following the link https://toolboxpro.app/blog/adding-shortcuts-to-an-app-1.
It works fine when running the extension target on device, but here comes the error "Could not run Make Uppercase,There was a problem with the app" when I running the main target.
There is no exception or breakpoint in Xcode so I don't know what's the problem. Any help will be appreciate, thanks.
