SwiftUI noob question: I understand why my ViewModel is being initialized twice, but why is it not being deinitialized?

It's created, then a second later when appState.show is changed, the view is recomputed, and view, and its ViewModel, are created anew. Cool! But why is the old one not deinitialized? What's holding onto it?

Sample code: https://gist.github.com/christianselig/d88b1a4d1989b973689ae62d4691162f

@christianselig I think you need to use a StateObject property wrapper for what you are trying to achieve: https://cocoacasts.com/what-is-the-difference-between-stateobject-and-observedobject#:~:text=Unlike%20StateObject%20%2C%20ObservedObject%20doesn't,managed%20elsewhere%20in%20the%20app.

@christianselig didn’t know that… will have to dive into that as well then. Any progress?
