title: Attributed String only to change Font Size, not the font name
body: <p>I am trying to set attributed text to a label. However, I want to change the size but not want to set the font name, how do I do that?</p>
  
  <pre><code>let myAttributedString = NSMutableAttributedString(string: "Some Text",
   attributes: [NSFontAttributeName:UIFont(name: "Georgia",size: 18.0)!])
