title: No placemark using MKLocalSearchCompleter
body: <p>I want to search for Cities only but MKLocalSearchRequest/MKLocalSearch can not be filtered. I tried MKLocalSearchCompleter but this is not giving me any placemarks... only name and subtitle. Is there a way to get placemarks from MKLocalSearchCompleter?</p>
  
  <p>I did the following to make it work. But I don't think it is good practice to call MKLocalSearchRequest again inside didSelectRowAt indexPath. But I can not save the first result and get the correct item out of this array in didSelectRowAt</p>
  
  <pre><code>var searchCompleter = MKLocalSearchCompleter()
  
  var searchResults = [MKLocalSearchCompletion]()
  
  extension SearchTableViewController : UISearchResultsUpdating {
  
  public func updateSearchResults(for searchController: UISearchController) {
  
      guard let searchBarText = searchController.searchBar.text else { return }
  
      searchCompleter.queryFragment = searchBarText
  
      if searchCompleter.results.count &gt; 0 {
  
          let searchRequest = MKLocalSearchRequest()
  
          let search = MKLocalSearch(request: searchRequest)
          search.start { (response, error) in }
      }
  }
  }
  extension SearchTableViewController: MKLocalSearchCompleterDelegate {
  
  func completerDidUpdateResults(_ completer: MKLocalSearchCompleter) {
      searchResults = completer.results
      self.tableView.reloadData()
  }
  
  func completer(_ completer: MKLocalSearchCompleter, didFailWithError error: Error) {
      // handle error
  }}
  
  extension SearchTableViewController {
  override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
      return searchResults.count
  }
  
  override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -&gt; UITableViewCell {
      let cell = tableView.dequeueReusableCell(withIdentifier: "SearchCell")!
     // let selectedItem = matchingItems[indexPath.row]
      let searchResult = searchResults[indexPath.row]
  
      cell.textLabel?.text = searchResult.title
      cell.detailTextLabel?.text = searchResult.subtitle
  
      return cell
  }
  
  override func tableView(_ tableView: UITableView, didSelectRowAt indexPath:IndexPath) {
  
  
      let searchRequest = MKLocalSearchRequest(completion: searchCompleter.results[indexPath.row])
  
      let search = MKLocalSearch(request: searchRequest)
      search.start { (response, error) in
  
          let placemark = response?.mapItems[0].placemark
  
          self.onSearchMapChanged?(placemark!.coordinate)
      }
  }
