title: XCUITest - Open iOS settings and change date/time
body: <p>Is it possible to change a device's date/time settings within a UI test? </p>
  
  <p>I'm able to open the Settings app, naviguate to General > Date &amp; Time and turn off the "Set Automatically" button. However, I can't find a way to change the pickerWheel value. </p>
  
  <pre><code>let settingsApp = XCUIApplication(bundleIdentifier: "com.apple.Preferences")
  settingsApp.launch()
  settingsApp.tables.cells["General"].tap()
  settingsApp.tables.cells["Date &amp; Time"].tap()
  settingsApp.switches["Set Automatically"].tap()
  // Change pickerWheel value?
  </code></pre>
  
  <p>Any thoughts? Is it at all possible? </p>
  
  <p>Thanks!</p>
