title: UIPickerView - Loop the data
body: <p>I'm currently developing an app using Swift where I use a UIPickerView, see below for image. Currently the UIPickerView stops when the user has scrolled to the last data, but i want it no never stop. I want it to be possible to start from the first data by just keep on scrolling when you're at the bottom. Or scroll up when at the top. I want it to be like Apple's Countdown where you can drag up or down whenever you want.</p>
  
  <p><strong>How I want it to be:</strong></p>
