テーブルビューのSwift MKMapItemデータソースが機能しません

Question

ArrayのMKMapItemをデータソースに使用しています。データソースにはテストで10個の項目がありますが、データをロードしようとするとアプリケーションがクラッシュします：

2016年9月17日22：17：58.097901アプリ[460：48227] で*アサーション障害 - [のUITableView _configureCellForDisplay：forIndexPath：]、/BuildRoot/Library/Caches/com.apple.xbs /Sources/UIKit/UIKit-3599.6/UITableView.m:8035 2016-09-17 22：17：58.099698 app [460：48227] * がキャッチされていないため、アプリを終了しています例外 'NSInternalInconsistencyException'、理由： 'UITableView（;層=; contentOffset：{0、-64}; contentSize：{768、440}>）は、そのデータソース （）」から細胞を得ることができなかった

マイコード：私のテスト例で

extension LocationSearchTable : UISearchResultsUpdating { 
    @available(iOS 8.0, *) 
    public func updateSearchResults(for searchController: UISearchController) { 
     guard let mapView = mapView, 
      let searchBarText = searchController.searchBar.text else { return } 

     print(searchBarText) 

     let request = MKLocalSearchRequest() 
     request.naturalLanguageQuery = searchBarText 
     request.region = mapView.region 
     let search = MKLocalSearch(request: request) 
     search.start { response, _ in 
      guard let response = response else { 
       return 
      } 
      print(response.mapItems) 
      self.matchingItems = response.mapItems 
      self.tableView.reloadData() 
     } 
    } 

    func updateSearchResultsForSearchController(searchController: UISearchController) { 
     guard let mapView = mapView, 
      let searchBarText = searchController.searchBar.text else { return } 
     let request = MKLocalSearchRequest() 
     request.naturalLanguageQuery = searchBarText 
     request.region = mapView.region 
     let search = MKLocalSearch(request: request) 
     search.start { response, _ in 
      guard let response = response else { 
       return 
      } 
      self.matchingItems = response.mapItems 
      self.tableView.reloadData() 
     } 
    } 
} 

extension LocationSearchTable { 
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     return matchingItems.count 
    } 

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
     let cell = tableView.dequeueReusableCell(withIdentifier: "cell")! 
     let selectedItem = matchingItems[indexPath.row].placemark 
     cell.textLabel?.text = selectedItem.name 
     cell.detailTextLabel?.text = parseAddress(selectedItem: selectedItem) 
     return cell 
    } 
} 

extension LocationSearchTable { 
    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
     let selectedItem = matchingItems[indexPath.row].placemark 
     handleMapSearchDelegate?.dropPinZoomIn(placemark: selectedItem) 
     dismiss(animated: true, completion: nil) 
    } 
}
