SwiftUI Map annotations don't show up

I'm using Xcode 14.0 beta 3 (14A5270f) on macOS 13.0 beta 3 (22A5295h).

SwiftUI Map with annotationItems: and annotationContent: doesn't seem to work. No annotations show up on the map, either with MapMarker or MapAnnotation. I tried running the code below on the same macOS as well as iOS 16.0 beta 3 (20A5312g).

Is this a beta software bug or is there anything wrong with the code?

import SwiftUI
import MapKit

struct Place: Identifiable {
    let id: String
    let location: CLLocationCoordinate2D
    init(id: String, latitude: CLLocationDegrees, longitude: CLLocationDegrees) {
        self.id = id
        self.location = CLLocationCoordinate2D(latitude: longitude, longitude: longitude)
    }
}


struct ContentView: View {
    @State private var mapCoordinateRegion: MKCoordinateRegion = .init(.world)
    
    let places = [Place(id: "test", latitude: 37.3346917, longitude: -122.0111262)]
    
    var body: some View {
        Map(coordinateRegion: self.$mapCoordinateRegion, showsUserLocation: true, annotationItems: self.places) { place in
            MapMarker(coordinate: place.location, tint: .blue)
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
