I'm playing around with custom actor executors a bit ... as seen in What's new in Swift at WWDC 2023... The following code errors out: @available(iOS 17.0, *) actor TestActor { private let queue: DispatchSerialQueue nonisolated var unownedExecutor: UnownedSerialExecutor { queue.asUnownedSerialExecutor() } ... Value of type 'DispatchSerialQueue' has no member 'asUnownedSerialExecutor' There is the _DispatchSerialExecutorQueue that actually does provide the asUnownedSerialExecutor() function ... This conflicts a bit with what Doug said during the talk... "The synchronization of actors via dispatch queues is made possible because dispatch queue conforms to the new SerialExecutor protocol." https://developer.apple.com/wwdc23/10164?time=2206

I'm trying to see what I am doing wrong ... So I created this simple app where the stateobject Retainer won't get deallocated when I pop the view off the stack: import SwiftUI struct ContentView: View { var body: some View { NavigationView { List { NavigationLink("To Retain Cycle") { RetainCycleView() } } .navigationTitle("Retain Cycle Demo") } .navigationViewStyle(.stack) } } struct RetainCycleView: View { @StateObject var model = Retainer() // @State var enteredText: String = "" var body: some View { VStack(alignment: .leading, spacing: 4) { Text("Navigate back to the previous view.") Text("You will see that 'Retainer' was NOT deallocated.") Text("(it's deinit function prints deallocing Retainer)") .font(.callout) } .padding() .searchable(text: $model.enteredText) // ^---- retain cycle // .searchable(text: $enteredText) // ^---- no retain cycle when using the @State var } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } } class Retainer: ObservableObject { @Published var enteredText: String = "" init() { print("instantiated Retainer") } deinit { print("deallocing Retainer") } } I filed feedback but I am not entirely sure that this isn't me making some mistake ... Please help me
