Closure ioslation and Actor

Using Swift
,
1

Hello Folks,

I have this code here. I'm getting the error, see screenshot.

Assumptions:

  • Is the code on line 11 running on the MainActor and Not the FactoryActor? even through the closure is invoked on line 22 in the factory actor
  • Can't modify the NoneSendableWorkUnit, b/c it's a SwiftData @Model

Question:

  • is there a way to run line 11 in the factory actor isolation context?

Code:

1. import SwiftUI
2. @main
3. struct MyApp: App {
4.     let factory = Factory()
5.     
6.     var body: some Scene {
7.         WindowGroup {
8.             Text("hello")
9.                 .task {
10.                     await factory.enqueue { unit in
11.                         unit.work += 1
12.                     }
13.                 }
14.         }
15.     }
16. }
17. class NoneSendableWorkUnit {
18.     var work: Int = 0
19. }
20. actor Factory {
21.     func enqueue(work: (NoneSendableWorkUnit) -> Void) async {
22.         work(NoneSendableWorkUnit())
23.     }
24. }

Looks like my solution is marking the closure as @Sendable
