@0xtim I created the Acronym.swift file via Xcode and went through the steps.
Iām receiving a Use of unresolved Identifier 'Acronym' error even though the file is there? Iām not sure what is wrong. Using the toolchain 4.1 and vapor-3.0.0-rc-1
Edit: Figured it out, when creating the file from Xcode it sets the Target Membership to your project name.
You need to uncheck that and set the target to be App. Then it should work
You change this in the File Inspector in the Utilities bar (right side bar).
