I have the following code:

import SwiftUI
import Observation

struct ContentView: View {
    
    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundStyle(.tint)
            Text("Hello, world!")
        }
        .padding()
    }
    
}

@Observable class ViewModel {
    
    struct TestInfo {
        var myId:Int
    }
    
    @MainActor var info:TestInfo?
    
    func setupInfo() async {
        
        var tmp:TestInfo?
        
        await CoreData.shared.context.perform {

            /// some core data work and then we set tmp
            tmp = TestInfo(myId: ....)
        }
        
        
        await MainActor.run {
            info = tmp /// ERROR: Reference to captured var 'tmp' in concurrently-executing code
        }
        
    }
    
}

I would like to know how to fix this error. I setup tmp within the core data context closure and would like to then set info to tmp.
