title: UIPickerView and UI Unit Test: How to get values of UIPickerWheel?
body: <p>Recently I had a bad headache (and I'm still struggling) to find out how to retrieve all values inside an UIPickerWheel. For me should be enough to move at particular row of the wheel, but I can't! So frustrating! I tried to scroll row by row to retrieve all values (<a href="https://stackoverflow.com/a/39300344/821407">https://stackoverflow.com/a/39300344/821407</a>) but it's so slow! Any clue? </p>
  
  <p>NB: I can't use adjustToPickerWheelValue because my root problem is that I don't know the value since they are dynamic and I would like to avoid launchArguments/launchEnvironment.</p>
