I am creating a Medical App using SwiftUI. I am trying to make a treatment view that provides a different set of answers (fetched from a .json) based on the answer to a certain set of questions.
I have tried this (see below) but I am experiencing errors with it. I figured it would be best to get some other opinions before diving down this rabbithole.
