title: how do I change text in a label with swift?
body: <p>I'm trying to change the text on a label in a simple iOS app.</p>
  
  <p>The idea is to write a message in a textField and have it change the label once I press a button.</p>
  
  <p>the <strong>objective-c</strong> code states the following:</p>
  
  <pre><code>[self.simpleLabel setText:message]
  </code></pre>
  
  <p>simpleLabel: is associated with the <code>UILabel</code>
  <code>setText:</code> is the method
  message: is a variable set in a previous line</p>
  
  <p>How would I write this in swift?</p>
  
  <p>I tried combing through the Apple documentation but came up with nothing.</p>
