Note that SwiftUI only notice changes in variable's value only when the value is @State or @ObservedObject (it's possible to make custom type, but that aside).
Thank you again. I have that mechanism already working with the timer, which is a component of a struct in the model that holds all of the relevant variables for t=driving the app. I am just confused as to setting up the publisher but, with your help, I have toiled long today and will bring a fresh overnight skull to it tomorrow.
