title: Iterate an array w/ explicit object type in Swift
body: <p>I have an array:</p>
  
  <pre><code>let individualScores = [75, 43, 103, 87, 12]
  </code></pre>
  
  <p>And I iterate like this:</p>
  
  <pre><code>for score in individualScores {
  
  }
  </code></pre>
  
  <p>However, is there a way to declare the object type explicitly?  I think it would come in handy later w/ custom objects, or other reasons.  Something like:</p>
  
  <pre><code>for Integer score in individualScores {
  
  }
  </code></pre>
