title: Set the value of multiple variables
body: <p>In a UIStackView, I have four labels corresponding to four <code>IBOutlet</code> variables named <code>lbl_0</code>, <code>lbl_1</code>, <code>lbl_2</code>, <code>lbl_3</code>. </p>
  
  <p>Sometimes, I need to set their value to an empty string. I thought I could do something "flashy" like the following:</p>
  
  <pre><code>// inside a loop body
  cell["lbl_"+i].text = ""
  </code></pre>
  
  <p>but it seems I can't ("no subscript members" error).</p>
  
  <p>So, aside from setting the value this way:</p>
  
  <pre><code>cell.lbl_0.text = ""
  cell.lbl_1.text = ""
  cell.lbl_2.text = ""
  cell.lbl_3.text = ""
  </code></pre>
  
  <p>is there any other way to set the value of these labels?</p>
