title: SceneKit crash on iPad Air 2
body: <p>I am developing an iPad App using SceneKit. It is still under development, but I have a few users testing via TestFlight. </p>
  
  <p>One user has an iPad Air 2 which is consistently crashing. The App works OK on my iPad Air, a number of iPad 2 devices and the iPad simulator. </p>
  
  <p>Crash logs from the iPad Air 2 all state the crash is caused by 'gpus_ReturnGuiltyForHardwareRestart'. The offending thread does not link back to my code so I am unsure how to resolve this.</p>

  <p>I do not at present have access to an iPad Air 2.</p>
  
  <p>Any suggestions on how I can overcome this issue?</p>
  
  <p>Many Thanks</p>
