MVVM examples for create/edit?

[TheGeekPharaoh]

I loved your Medium article, and this sample app is very helpful in learning about MVVM in SwiftUI. I'm new to the pattern so this was great! Any chance you could add an example showing how you would model adding a book to the list or editing the details of an existing one? All of the MVVM articles and tutorials I've found talk about listing/viewing, but none talk about write operations!
