   Hi @BryanJBryce, the StandupsList view holds onto its observable object like so:

   struct StandupsList: View {
     @ObservedObject var model: StandupsListModel
     …
   }

   …which makes the parent responsible for providing the model. So it will not be recreated unless the parent decides to recreate it.

   And the parent is the app entry point:

   @main
   struct StandupsApp: App {
     var body: some Scene {
       WindowGroup {
         StandupsList(
           model: StandupsListModel()
         )
       }
     }
   }

   And that shows that only a single model is created for the entire duration of the app.

   Also I am going to move this to a discussion since it isn't really an issue with the code sample.
