'init()' has been explicitly marked unavailable here (MapKit.MKPlacemark)

Hi!

Im making an app in SwiftUI and following https://www.youtube.com/watch?v=WTzBKOe7MmU tutorial on youtube for maps integration and finding nearby points of interest, in the last part of the video we're making an list of all results of the search. I get an error message "init() is unavailable on iOS" and "'init()' has been explicitly marked unavailable here (MapKit.MKPlacemark)", on this part of the code:

struct PlaceListView_Previews: PreviewProvider {
  static var previews: some View {
    PlaceListView(landmarks: [Landmark(placemark: MKPlacemark())], onTap: {})
  }
}

And this is how my Landmark struct looks like:

struct Landmark {
   
  let placemark: MKPlacemark
   
  var id: UUID {
    return UUID()
  }
   
  var name: String {
    self.placemark.name ?? ""
  }
   
  var title: String {
    self.placemark.title ?? ""
  }
   
  var coordinate: CLLocationCoordinate2D {
    self.placemark.coordinate
  }
}

It works for my friend but not for me, does somebody know the reason?
