title: Is there a way to get the string value of a picker wheel that is an XCUIElement?
body: <p>I know that this exists:
  <code>func adjust(toPickerWheelValue pickerWheelValue: String)</code>, but I'm not trying to adjust the value. I want to make sure that the value is the string that I'm expecting after I've moved it. </p>
  
  <p>I tried doing <code>.value</code> on the picker wheel element, but it's giving me an <code>Any</code> type with the string that I need in there, plus some extra stuff.</p>
  
  <p>Let's say the printout of the screen is this:</p>
  
  <pre><code>Attributes: Application, pid: 64445, label: ‘App’
  Element subtree:
   →Application, 0x60000263a150, pid: 64445, label: ‘App’
      Window (Main), 0x600002639110, {{0.0, 0.0}, {320.0, 568.0}}
        Other, 0x6000026396c0, {{0.0, 0.0}, {320.0, 568.0}}
          Picker, 0x600002639040, {{0.0, 352.0}, {320.0, 216.0}}
              PickerWheel, 0x600002639520, {{0.0, 314.5}, {103.0, 291.0}}, value: 0 hours
              PickerWheel, 0x600002639380, {{108.0, 314.5}, {103.0, 291.0}}, value: 13 min
  </code></pre>
  
  <p>I'll print out <code>app.pickerWheels.element(boundBy: 0).value</code> in the console and get this</p>
  
  <pre><code>Optional&lt;Any&gt;
      - some : 0 hours
  </code></pre>
  
  <p>I explicitly only want the <code>0 hours</code> so I can assert that the picker wheel says that.</p>
