I'm getting sporadic reports of users who purchase my auto-renewing subscription and there is no receipt data on their device. After the purchase is made, I parse the receipt and save the expire date into UserDefaults. Then whenever you open the app I check the expire date against today and if its later, you can access my content.
I've created a gist with my relevant code that parses the receipt and saves the expireDate that is kicked off in my appDelegate's handle purchase:
extension AppDelegate: SKPaymentTransactionObserver {
func paymentQueue(_ queue: SKPaymentQueue,
updatedTransactions transactions: [SKPaymentTransaction]) {
for transaction in transactions {
switch transaction.transactionState {
case .purchasing:
handlePurchasingState(for: transaction, in: queue)
case .purchased:
handlePurchasedState(for: transaction, in: queue)
case .restored:
handleRestoredState(for: transaction, in: queue)
case .failed:
handleFailedState(for: transaction, in: queue)
case .deferred:
handleDeferredState(for: transaction, in: queue)
}
}
}
func handlePurchasingState(for transaction: SKPaymentTransaction, in queue: SKPaymentQueue) {
print("User is attempting to purchase product id: \(transaction.payment.productIdentifier)")
}
func handlePurchasedState(for transaction: SKPaymentTransaction, in queue: SKPaymentQueue) {
print("User purchased product id: \(transaction.payment.productIdentifier)")
queue.finishTransaction(transaction)
SubscriptionService.shared.uploadReceipt { (success) in
DispatchQueue.main.async {
//self.updateWatchContext()
NotificationCenter.default.post(name: SubscriptionService.purchaseSuccessfulNotification, object: nil)
}
}
}
func handleRestoredState(for transaction: SKPaymentTransaction, in queue: SKPaymentQueue) {
print("Purchase restored for product id: \(transaction.payment.productIdentifier)")
queue.finishTransaction(transaction)
SubscriptionService.shared.uploadReceipt { (success) in
DispatchQueue.main.async {
NotificationCenter.default.post(name: SubscriptionService.restoreSuccessfulNotification, object: nil)
}
}
}
func handleFailedState(for transaction: SKPaymentTransaction, in queue: SKPaymentQueue) {
queue.finishTransaction(transaction) //The RW tutorial did NOT finish the transaction, but iOS Slack said I should
print("Purchase failed for product id: \(transaction.payment.productIdentifier) on \(String(describing: transaction.transactionDate)) and this transaction is currently listed as \(transaction.transactionState) because of this error \(String(describing: transaction.error))")
}
func handleDeferredState(for transaction: SKPaymentTransaction, in queue: SKPaymentQueue) {
print("Purchase deferred for product id: \(transaction.payment.productIdentifier)")
}
}
A few users have told me that they cannot unlock the content even though they subscribed (these users also said they had purchased the annual subscription, I also have a monthly option)...I had one user install a beta version with a Firebase integration so that I could push the receipt and expire date to the console to see what it says and it appears that there is no expire date or receipt on his device. Any thoughts on what the issue is and why this seems to only be the case in the UK? My active user base is roughly 600 and I haven't heard of this issue outside of the UK.
