title: StoreKit Error Codes
body: <p>Does anyone know where I can find a list of all of StoreKit's error codes and descriptions. It was hinted at in WWDC 2014, session 303 (Optimizing In-App Purchases) but the person never provided a URL and I can't for the life me find the correct document.</p>
  
  <p>I found SKError.h - but it doesn't seem to be the complete list (ie. <code>Error Domain=SSErrorDomain Code=16 "Cannot connect to iTunes Store"</code> is not mentioned in there, nor does the enum go as high as 17 items).</p>
  
  <p>Any help would be greatly appreciated!</p>
