title: XCode Playground: Couldn't Lookup Symbols
body: <p>Co-working with a friend on a SwiftUI Playground and MapKit won't load on my machine, but it does on his.</p>
  <p>The error that I receive is:</p>
  <pre><code>expression failed to parse:
  error: Couldn't lookup symbols:
    nominal type descriptor for _MapKit_SwiftUI._DefaultMapContent
  </code></pre>
  <p>The relevant code is:</p>
  <pre><code>import SwiftUI
  import PlaygroundSupport
  import MapKit
  
  struct SearchView: View {
      @State private var mapRegion = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 35.1195684, longitude: -90.0632266), span: MKCoordinateSpan(latitudeDelta: 0.2, longitudeDelta: 0.2))
      ...
  
      var body: some View {
          ZStack{
              Map(coordinateRegion: $mapRegion)
                  .zIndex(0)
                  .onChange(of: mapRegion) { _ in
                      userMovedMap = true
                      print(userMovedMap, showReloadButton, timerAnimation.isActive)
                      timerAnimation.objectWillChange.send()
                  }
              ...
  }
  
  PlaygroundPage.current.setLiveView(SearchView()
      .frame(width: SCREEN_SIZE.width, height:SCREEN_SIZE.height))
  </code></pre>
  <p>Why won't this playground run on my machine while it does on his? (Using Xcode 13.4.1 and MacOS 12.5)</p>
