title: Multi request for distance via MKDirections
body: <p>I'm coding an application that it use MapKit features. When I make request with for loop to get directions for many locations using MapKit's MKDirections , it gives error as  &quot;Directions is not available &quot; with following details :</p>
  <pre><code>Error Domain=MKErrorDomain Code=3 &quot;Directions Not Available&quot; UserInfo={NSLocalizedFailureReason=Route information is not available at this moment., MKErrorGEOError=-3, MKErrorGEOErrorUserInfo={
  details =     (
              {
          intervalType = short;
          maxRequests = 50;
          &quot;throttler.keyPath&quot; = &quot;app:lszlp.nobetciEczane/0x20200/short(default/any)&quot;;
          timeUntilReset = 54;
          windowSize = 60;
      }
  );
  timeUntilReset = 54; ```
