title: Achieve AYVibrantButton effect with Swift 3
body: <p>I have a project that uses the 3rd party API called <a href="https://github.com/a1anyip/AYVibrantButton" rel="nofollow">AYVibrantButton</a> (please take a look in the link).</p>
  
  <p>The problem is that this API doesn't support Swift 3, so I'm searching for a way to achieve the same effect ("Invert style with vibrancy effect") with Swift 3 (another 3rd party API or a way to create it without using any 3rd parties, the easier one).</p>
  
  <p>Anyone knows?</p>
  
  <p>Thanks!</p>
