Thank you, that worked.
Is it important to put my string catalog in a folder called Resources? (I realized mine had a typo but it still worked).
When working with SF symbols in Texts, I'm wondering how this should work with generated symbols:
Previously this worked (with strings instead of symbols):
let image = Image(systemName: "exclamationmark")
Text("myKey(image)", bundle: .module)
When converting this generated key to a symbol it uses a String argument in the generated function :(
