title: realm.objects().filter does not work with Resuts<T>
body: <p>I tried to do query objects from Realm using <code>RealmSwift framefowk</code> with predicates:</p>
  
  <pre><code>realm.objects(Train).filter("ANY route IN %@", realm.objects(Route))
  </code></pre>
  
  <p>Error is:</p>
  
  <blockquote>
    <p>Cannot invoke 'filter' with an argument list of type '(String,
    Results)'</p>
  </blockquote>
  
  <p>The same code worked with <code>Realm framework</code> but does not work with <code>RealmSwift framework</code>.</p>
  
  <p>What am I doing wrong ?</p>
