title: Unity IAP for IOS -- No App Receipt found
body: <p>I am trying set up some in-app purchases through Unity IAP for iOS devices. Registering the various product IDs, the initialization process seems to have passed successfully. However, when I tried to make a purchase using an iPad connected to a Mac, I received an error message on XCode saying:</p>
  
  <pre><code>UnityIAP: No App Receipt found
  </code></pre>
  
  <p>The purchase failed. The reason given for the error was: Unknown.</p>
  
  <p>On the Unity editor, the purchase did go through without any problem.</p>
  
  <p>So what could be the reason? What is an App Receipt?</p>
