iOS App Store receipt file does not exist

Question

I try to read the App Store receipt (iOS7) in the sandbox/development environment. I make a SKReceiptRefreshRequest, if the file does not exist (which is always). It always calls request:didFailWithError: on my delegate. Why is that? I thought Apple will provide fake receipts while developing for testing?

Answer 1

Reminder for myself and others facing stupid problems like this: Log in with a test user account!

Everything works now. Thanks guys
