title: Detect if an iPad can use an Apple Pencil (is iPad Pro)
body: <p>Is there a way to detect if the model of an iPad supports Apple Pencil?</p>
  
  <p>I can check for the [UIDeviceHardware platformString] which returns the model of iPad and I can get the Pro models, but I would like a definitive solution that works even for future iPad Pro models. </p>
