title: GVR Audio Engine for iOS crashing
body: <p>I'm trying to run a program using the Google Resonance Audio SDK for iOS, but every time I try to initialize the GVRAudioEngine, the application crashes and this error appears in XCode:</p>
  
  <pre><code>Thread 1: EXC_BAD_ACCESS (code=1, 
        address=0xffffffffffffffe8)
  </code></pre>
  
  <p>Does anyone have experience running Google Resonance Audio on iPhone?</p>
  
  <p>Specifically, I'm trying to run the program from this tutorial, <a href="https://developers.google.com/resonance-audio/develop/ios/getting-started" rel="nofollow noreferrer" title="Tresure Hunt Demo">Treasure Hunt Demo</a>, the example tutorial provided by Google, but using Xcode 10.0 and iOS 11 or 12, I get the error message above while following the directions.</p>
