Hi all. I'm attempting to add consumable IAPs to my IOS application. My code seems to work fine when I'm testing locally using the storekit.configuration; however, when I switched over to Sandbox testing, I get the Purchase pop-up in the app, and my PaymentQueue observer hits the "purchasing" status, but that's it. After I hit Purchase on the pop-up, my PaymentQueue observer never hits again. The purchase pop-up says the purchase was successful in the app, and it goes away, but it pops back up a few seconds later. In testing, my PaymentQueue observer hits and goes to the "purchased" case, so things work as-expected. I've set my test account up in Sandbox as per Apple's instructions. Has anyone else run into this? Is there a way for me to see the Queue real-time so I can see what's going on in there? My app is still in development - I'm testing in TestFlight, but haven't submitted for full AppStore review yet, in case that matters.... Here's the code for my In-App Purchase manager, in case that helps. // // IAPManager.swift // // import Foundation import StoreKit final class IAPManager: NSObject, SKProductsRequestDelegate, SKPaymentTransactionObserver { static let shared = IAPManager() var products = [SKProduct]() private var completion: ((Int) -> Void)? enum Product: String, CaseIterable { case tokens_10 var count : Int { switch self { case .tokens_10: return 10 } } } public func GetProducts() { //Load all the product in our Product enum in let request = SKProductsRequest(productIdentifiers: Set(Product.allCases.compactMap({ $0.rawValue }))) request.delegate = self request.start() } func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) { print("Products found : \(response.products.count).") self.products = response.products } public func purchase(product : Product, completion: @escaping ((Int) -> Void)) { //Make sure the user is allowed to purchase stuff guard SKPaymentQueue.canMakePayments() else { return } //Make sure the product IDs match guard let storeKitProduct = products.first(where: { $0.productIdentifier == product.rawValue}) else { return } self.completion = completion let paymentRequest = SKPayment(product: storeKitProduct) SKPaymentQueue.default().add(self) SKPaymentQueue.default().add(paymentRequest) } func paymentQueue(_ queue: SKPaymentQueue, shouldAddStorePayment payment: SKPayment, for product: SKProduct) -> Bool { print("Should add payment hit.") return true } //MARK Error - 2024-02-02: Never hitting "case .purchased" when using Sandbox func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) { transactions.forEach( { switch $0.transactionState { case .purchasing: print("Transaction purchasing.") break case .purchased: print("Transaction PURCHASED.") if let product = Product(rawValue: $0.payment.productIdentifier) { completion?(product.count) } SKPaymentQueue.default().finishTransaction($0) SKPaymentQueue.default().remove(self) break case .failed: print("Transaction failed.") break case .restored: print("Transaction restored.") break case .deferred: print("Transaction deferred.") break @unknown default: break } }) } } Any help would be greatly appreciated!
