title: Swift - Placeholder long text - cut the middle
body: <p>I have <code>UITextField</code> with long placeholder like this:
  "QWERTYUIOPASDFGHJKLZXCVBNM", but my textfield is small and when I use function <code>textField.adjustsFontSizeToFitWidth = true</code> the <code>minimumFontSize</code> that I can set is 9 but still I can't fit the text into the textField. I want to cut the middle of the text and I expect the text to be "QWERTY...CVBNM" how to do that?</p>
