same problem here. if later in code everywhere use [weak appModel] and never tap on "start again" ( at coaching overlay) - if will consume (after exit from that screen) approx 250mb. And it tap on "start again" - looks like ARKit view or caching overlay - makes strong ref. =(

For anyone who struggles like me : Add this .navigationViewStyle(StackNavigationViewStyle()) to core navigation view - in our case that's App. ScrumdingerApp.swift @main struct ScrumdingerApp: App {     @State private var scrums = DailyScrum.data     var body: some Scene {         WindowGroup {             NavigationView {                 ScrumsView(scrums: $scrums)             }             .navigationViewStyle(StackNavigationViewStyle())         }     } } Somehow it fixes everything :)
