Happens to me as well, but in my case I get the error: "An unknown error occurred". Payment succeeded, but I get an error as feedback.

Ok, we've been able to trace this, not fix it mind you, but at least we know exactly why it's happening. Basically, this occurs (for us) whenever a user needs to accept Apple's new Terms of Service agreement before making a purchase. When Apple updates their ToS, every App Store user needs to agree with them before making any more purchases, if your product is the first thing they try to purchase after the ToS are updated, Apple forces them to Accept or Decline them and that transition kicks back the "An unknown error occurred". The user presumably then accepts the new ToS, and continues to payment and that succeeds but the delegate functions for SwiftyKit don't catch that success. It's an odd use case but that's what we've found for our system.
