Free non-consumable in-app purchase with hosted content on Apples's servers
问题 Can non-consumable in-app purchases that include content hosted on Apple's servers be free? I couldn't find anything about this in the docs and as you can set in-app purchases to be free in iTunes connect, I assumed it was possible. I have set up a non-consumable in-app purchase on iTunes connect, uploaded some content and set its price to be free. Unfortunately when I request the products data using the product ID, I receive that ID in the SKProductsResponse.invalidProductIdentifiers array.
