title: Insert only 10 elements to an array
body: <p>I have a struct named <code>Thing</code>:</p>
  
  <pre><code>struct Thing {
    var name: String
    var description: String
  }
  </code></pre>
  
  <p>and an array <code>things = [Thing]()</code> that contains 100 elements.</p>
  
  <p>Now I want something like <code>elements.addObjectsFromArray(things.subarrayWithRange(NSMakeRange(0, 10)))</code> to populate my <code>tableView</code>, but </p>
  
  <blockquote>
    <p>[Thing] has no member addObjectsFromArray.</p>
  </blockquote>
  
  <p>I know <code>elements.insertContentsOf(things, at: 0)</code>, but it inserts all elements of <code>things</code>.</p>
  
  <p>How can I insert only 10 elements in needed range?</p>
