Information
This tool is utilising the logic from the sample project provided by Apple Here. For purchasing promotional offers developer needs some additional paramters to pass in for SKPayment before adding it in the payment queue. For example:
let discount = SKPaymentDiscount(identifier: offerIdentifier,
keyIdentifier: keyIDentifier,
nonce: UUID(uuidString: nonce),
signature: signature,
timestamp: NSNumber(value: timeStamp))
payment.paymentDiscount = discount
SKPaymentQueue.default().add(payment)NB: This tool works within a browser locally and does not sync keys. You can always revoke your keys from App Store Connect.Server side is required to get the additional parameters mainly because adding your private key inside your app's bundle isn't a good idea.
