title: How to implement autocomplete for cities with MapKit?
body: <p>I need to implement method which allows to receive list of cities (not full) by its first character. I thought I can use address autocompletion for this.</p>
  
  <p>For example I can do it in Google APIs: <a href="https://maps.googleapis.com/maps/api/place/autocomplete/json?input=V&amp;types=(cities)&amp;language=pt_BR&amp;key=YOUR_API_KEY" rel="noreferrer">https://maps.googleapis.com/maps/api/place/autocomplete/json?input=V&amp;types=(cities)&amp;language=pt_BR&amp;key=YOUR_API_KEY</a> 
  It returns 5 cities (because of types=cities) with "V" first character.</p>
  
  <p>But I don't have such parameter in MapKit from Apple. If I use MKLocalSearchCompleter I only have </p>
  
  <pre><code>enum MKSearchCompletionFilterType : Int {
      case LocationsAndQueries
      case LocationsOnly
  }
  </code></pre>
  
  <p>How I can resolve this problem and receive some cities by first character? Thanks!</p>
