The approach would be to iterate inside the map using ForEach() to add the markers. Add a title string property to IdentifiableAnnotation and display it as such: Map(coordinateRegion: $locationManager.region, interactionModes: .all, showsUserLocation: true, userTrackingMode: .none) { ForEach(courtAnnotations) { item in Marker(item.title, coordinate: item.annotation.coordinate) } }

When tapping anywhere on a Map view, I get a warning "Trying to convert coordinates between views that are in different UIWindows, which isn't supported. Use convertPoint:fromCoordinateSpace: instead." I'd guess it's got something to do with that.

Portals have been enhanced this year with the ability to cross portal boundaries. It's discussed around the 20 minute mark, "Portal Enhancements" in the following video: https://developer.apple.com/videos/play/wwdc2024/10103/
