MapKit not working in Swift Playgrounds

This is the complete Playground code:

import MapKit
import SwiftUI
import PlaygroundSupport


struct AddressSearchView: View {
    @State private var region = MKCoordinateRegion(
        center: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194),
        span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01)
    )
    var body: some View {
        VStack {
            Map(position: .constant(MapCameraPosition.region(region))) {
                
            }
            .frame(height: 300)
        }
    }
}

struct AddressSearchView_Previews: PreviewProvider {
    static var previews: some View {
        AddressSearchView()
    }
}

PlaygroundPage.current.setLiveView(AddressSearchView())

When I try to run this I get this in the debug console:

error: Couldn't look up symbols:

Hint: The expression tried to call a function that is not present in the target, perhaps because it was optimized out by the compiler.

the preview never shows up. If I use other SwiftUI components and not the map it works fine. What is happening?

Playground target is Swift 6 macOS (iOS does the same). Xcode 16.2
