title: Change UITextField width dynamically depends of content
body: <p>I have the same issue as here: <a href="https://stackoverflow.com/questions/18236661/resize-a-uitextfield-while-typing-by-using-autolayout">Resize a UITextField while typing (by using Autolayout)</a></p>
  
  <p>But It was resolved with <code>UITextView</code> and not with <code>UITextField</code>.</p>
  
  <p>This code doesn't help:</p>
  
  <pre><code>func textFieldDidChange(sender: UITextField) {
      sender.invalidateIntrinsicContentSize()
  }
  </code></pre>
  
  <p>I have <code>UITextField</code>(red background) and use AutoLayout with StackView:</p>

  <p>but <code>UITextField</code> change it width only when it is <code>resignFirstResponder</code>.
  Could you give me please any advice about the issue?
  I'm new in Swift and iOS Development. </p>
