title: How to find the offending file for 'fopen failed for data file: errno = 2 (No such file or directory)'
body: <p>I have a Swift/SpriteKit project with an <code>App Clip</code>. The app clip compiles on the Simulator (though it crashes when tested via TestFlight), but I receive the error <code>fopen failed for data file: errno = 2 (No such file or directory)</code>. <strong>However, the offending file is not named.</strong></p>
  <p>There are numerous SO questions on the topic of this error. But as far as I can tell, those questions do not address <em>how to find the offending file when it's not named in the logs</em>.</p>
  <p>My question is simple: What's the easiest way to find the name/location of the file in question when receiving this error?</p>
  <p>Thank you!</p>
  <p><strong>Edit:</strong> I'm also getting the following message:
  <code>Errors found! Invalidating cache...</code></p>
