StoreKit In App Purchase invalid product identifiers [duplicate]

Question

I am getting an empty array of product identifiers from SKProductsRequest.

I did the following steps:

1. Created a In App Purchase Test User account under 'Manage Users' in iTunes Connect

2. Created some in app purchase products under 'Manage Your In App Purchases'.

3. Loaded the app onto the iPhone, went to Settings → Store and logged out of the regular store

4. Set a breakpoint in the (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response callback

All the submitted Product ID's are in the response's invalidProductIdentifiers property. When submitting the request I tried both the Product IDs created during step 2 as well as those IDs prefixed with the Bundle ID.

Thanks in advance,

Raghu

Answer 1

I tried everything suggested in the Apple forums and here, and still couldn't get it to work.

Found the solution:

Your app needs to be transferred by Xcode for the sandbox to be enabled.

Your app needs to be built and installed locally by Xcode, not downloaded from the App Store.

Obvious, right? Well, if you are working with an update to an existing application, the device will still treat it as an App Store-installed app.

So delete the app from your device. Then install the app back onto the device using Build & Run with your device tethered to your Mac. It should work now :)

I've been compiling a list of the reasons product identifiers come back invalid. Here's a checklist of the potential causes:
