Hey everyone, I'm currently preparing an older iOS app for App Store release that includes a non-consumable In‑App Purchase using StoreKit 2. Everything works perfectly in the StoreKitTest environment inside Xcode – the product loads, the purchase flow runs, the transaction verifies. However, when I run the same app through TestFlight, I always get the error: ❌ Product not available - mapped to Here’s what I’ve already checked: ✅ The product ID is correct and matches what’s in App Store Connect (case-sensitive). ✅ The IAP is created in App Store Connect and includes: Title Product ID Price Tier Screenshot for review ✅ The App Store "Paid Applications" agreement is active. ✅ The app is using the correct bundle ID. ✅ I'm using Product.products(for: [productID]) from StoreKit 2. ✅ I’ve implemented fallback and retry logic (e.g. reload after delay). ✅ All IAP logic is wrapped in @MainActor and async-safe. As the App got Rejected on Review, the IAP is also now in the Rejected Status. Now the IAP shows status: 🟠 "Developer Action Required" And App Review rejected the IAP with the message: "Your first In‑App Purchase must be submitted together with a new app version." But if I add the App to the Test again and therefore the IAP, then the app will get Rejected again for App Completeness, IAP does not work... What am I doing wrong here? :) Thanks a lot in advance Cheers, Niklas

Dear Apple Technical Support Team, We have encountered a potential issue related to transaction handling while using StoreKit v2, and would greatly appreciate your assistance in confirming the behavior or providing any relevant guidance. Issue Description: When calling Transaction.unfinished and listening to Transaction.updates on the client side, we noticed that some transactions—despite having already been processed and successfully completed with finish()—are being returned again upon the next app launch, which results in duplicate receipt uploads. Current Handling Flow: 1. Upon app launch: • Iterate over Transaction.unfinished to retrieve unfinished transactions; • Simultaneously listen for transaction changes via Transaction.updates (e.g., renewals, refunds); 2. For each verified transaction, we immediately call await transaction.finish(); 3. We then construct a transaction model, store it locally, and report it to our backend for receipt verification; 4. After the server successfully verifies the receipt, the client deletes the corresponding local record; 5. On every app launch, the client checks for any locally stored receipts that haven’t been uploaded, and re-uploads them if necessary. Key Code Snippets: private static func verifyReceipt(receiptResult: VerificationResult) -> Transaction? { switch receiptResult { case .unverified(_, _): return nil case .verified(let signedType): return signedType } } public static func handleUnfinishedTransactions(payConfig: YCStoreKitPayConfig, complete: ((YCStoreKitReceiptModel?) -> Void)?) { Task.detached { for await unfinishedResult in Transaction.unfinished { let transaction = YCStoreKitV2Manager.verifyReceipt(receiptResult: unfinishedResult) if let transaction { await transaction.finish() if transaction.revocationDate == nil { let receipt = YCStoreKitV2Manager.createStoreKitReceiptModel( transation: transaction, jwsString: unfinishedResult.jwsRepresentation, payConfig: payConfig, isRenew: false ) complete?(receipt) } } } } } private func observeTransactionUpdates() -> Task<Void, Never> { return Task { for await updateResult in Transaction.updates { let transaction = YCStoreKitV2Manager.verifyReceipt(receiptResult: updateResult) if let transaction { await transaction.finish() if transaction.revocationDate == nil { let receipt = YCStoreKitV2Manager.createStoreKitReceiptModel( transation: transaction, jwsString: updateResult.jwsRepresentation, payConfig: self.payConfig, isRenew: false ) self.callProgressChanged(.receiptPrepared, receiptModel: receipt, errorType: .none, error: nil) } } } } } Our Questions: 1. Is it possible for Transaction.unfinished or Transaction.updates to return transactions that have already been finished? Specifically, if a transaction was successfully finished in a previous app launch, could it still be returned again during the next launch? 2. Are there any flaws in our current handling process? Our current sequence is: finish() → construct model → local save → report to server → delete after verification. Could this order lead to timing issues where StoreKit considers a transaction unfinished? 3. If we need your assistance in investigating specific user transaction records or logs, what key information should we provide? We greatly appreciate your support and look forward to your response to help us further optimize our transaction processing logic.

We got access into Advanced Commerce API and trying out the server APIs. I was trying out the Migrate a Subscription to Advanced Commerce API but the API was just simply returning not found to me with a generic error code 4040000 (this is undocumented in the API doc). Here is the request body { "descriptors": { "description": "User migrated from old plan to Essential", "displayName": "Essential Plan" }, "items": [ { "sku": "com.company.essential", "description": "A new subscription description after migration", "displayName": "Essential" } ], "requestInfo": { "requestReferenceId": "11aa3174-9aeb-41a6-996d-fc655a793c06" }, "storefront": "HKG", "targetProductId": "com.company.subscription.base", "taxCode": "C003-00-1" } Headers Authorization: Bearer <REQUEST_TOKEN> And the response { "errorCode": 4040000, "errorMessage": "Not found." } Am I doing something wrong or there will be additional configuration needed?

My Mac app fails to open for some users with the error: "ABC.app does not support the latest receipt validation requirements." I assume this is due to the update of the App Store receipt signing intermediate certificate with one that uses the SHA-256 algorithm. I cannot reproduce this myself and I have trouble figuring out how to address this issue. Below is the code that decrypts the receipt and verifies its signature. How does this code need to be updated to support the new signing certificate? Thanks a lot in advance! inline static void CheckBundleSignature(void) { NSURL *bundleURL = [[NSBundle mainBundle] bundleURL]; SecStaticCodeRef staticCode = NULL; OSStatus status = SecStaticCodeCreateWithPath((__bridge CFURLRef)bundleURL, kSecCSDefaultFlags, &amp;staticCode); if (status != errSecSuccess) { [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to validate bundle signature: Create a static code", nil]; } NSString *requirementText = @"anchor apple generic"; SecRequirementRef requirement = NULL; status = SecRequirementCreateWithString((__bridge CFStringRef)requirementText, kSecCSDefaultFlags, &amp;requirement); if (status != errSecSuccess) { if (staticCode) CFRelease(staticCode); [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to validate bundle signature: Create a requirement", nil]; } status = SecStaticCodeCheckValidity(staticCode, kSecCSDefaultFlags, requirement); if (status != errSecSuccess) { if (staticCode) CFRelease(staticCode); if (requirement) CFRelease(requirement); [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to validate bundle signature: Check the static code validity", nil]; } if (staticCode) CFRelease(staticCode); if (requirement) CFRelease(requirement); } static NSData *DecodeReceiptData(NSData *receiptData) { CMSDecoderRef decoder = NULL; SecPolicyRef policyRef = NULL; SecTrustRef trustRef = NULL; @try { OSStatus status = CMSDecoderCreate(&amp;decoder); if (status) { [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to decode receipt data: Create a decoder", nil]; } status = CMSDecoderUpdateMessage(decoder, receiptData.bytes, receiptData.length); if (status) { [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to decode receipt data: Update message", nil]; } status = CMSDecoderFinalizeMessage(decoder); if (status) { [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to decode receipt data: Finalize message", nil]; } NSData *ret = nil; CFDataRef dataRef = NULL; status = CMSDecoderCopyContent(decoder, &amp;dataRef); if (status) { [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to decode receipt data: Get decrypted content", nil]; } ret = [NSData dataWithData:(__bridge NSData *)dataRef]; CFRelease(dataRef); size_t numSigners; status = CMSDecoderGetNumSigners(decoder, &amp;numSigners); if (status) { [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to check receipt signature: Get singer count", nil]; } if (numSigners == 0) { [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to check receipt signature: No signer found", nil]; } policyRef = SecPolicyCreateBasicX509(); CMSSignerStatus signerStatus; OSStatus certVerifyResult; status = CMSDecoderCopySignerStatus(decoder, 0, policyRef, TRUE, &amp;signerStatus, &amp;trustRef, &amp;certVerifyResult); if (status) { [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to check receipt signature: Get signer status", nil]; } if (signerStatus != kCMSSignerValid) { [NSException raise:@"MacAppStore Receipt Validation Error" format:@"Failed to check receipt signature: No valid signer", nil]; } return ret; } @catch (NSException *e) { @throw e; } @finally { if (policyRef) CFRelease(policyRef); if (trustRef) CFRelease(trustRef); if (decoder) CFRelease(decoder); } }

I'm considering developing an app where users can create their own subscription plans by freely setting their prices, similar to YouTube's membership feature. I understand that in-app purchases must be used to unlock features within the app. With that in mind, I searched for APIs to enable this functionality but couldn't find relevant information. When I contacted Apple directly, they mentioned that they couldn't provide specific answers unless the app is under review. If anyone has knowledge about the following points, I would greatly appreciate your response: Is it possible to implement a feature similar to YouTube's membership using in-app purchase APIs? If it's not feasible with in-app purchases, is it allowed to use external payment services like Stripe?

I am testing sandbox subscribe but I always recieve DID_FAIL_TO_RENEW I try to create new sandbox account and clear purchase history but not work can anyone help?

I have an app which is already on App Store with In-app purchase. Now I want to integrate In-app purchase in my another app for the same products as in the existing app. Both the apps are using same Apple Account. Can I reuse those Product Ids from the first app in the second one. If yes, what is the ways to use them. Thank you in advance.

Whether using Storefront.current?.countryCode or SKPaymentQueue.default().storefront?.countryCode, both are returning "USA" only. (It used to return the correct country code before the update.) In the sandbox environment, the country code is returned correctly, but in the TestFlight environment, it always returns "USA". There's no mention of this behavior in the beta release notes, so I'm posting it here for visibility.

I cannot explain how frustrating this is. Not that I want to compare to Android, but in 3 years of QA Testing my app, Android works like a dream, while iOS fights with me EVERY SINGLE STEP OF THE WAY. Hopefully someone here can tell me what I am missing/doing wrong/which god I must appease to get this to work. I have 3 REAL iPhones of varying iOS versions and ages. But they are all proper actual iPhones. We use google accounts at this company, so my primary email is a gmail one. I have created MANY sandbox accounts inside App Store Connect. Currently I have 2, and 2 of my devices (both 14's one of which is a Pro) have my Primary account as the main account for the device. But they both also have a Sandbox account which is simply my main email with a +sandbox in it to make it a new unique email. Here is the problem, nothing works as expected ever. I can install my Staging and Production apps from TestFlight, then I can make a subscription purchase as a customer would and I SHOULD see that subscription in my Sandbox right? That's the point of a Sandbox and TestFlight is it not? But in ALL cases whenever I try to view my 'Sandbox Subscriptions' it tells me I don't have any. Now, sometimes, very occasionally, I get a specific error message inside my app when attempting to make a purchase, this one states something like 'You already have a subscription, please restore it instead...' which makes no sense. Since it clearly states that I have none. But this message has a 'Manage' button to manage my subscriptions, tapping it lads me to a windows which amazing DOES have a subscription in it. But attempting to 'Cancel' it does nothing, just refreshes the screen to be the same. Now I think that this subscription is actually attached to the primary account on the device and NOT the sandbox account. So when this happens I cannot subscribe, I cannot restore, and I cannot manually alter the subscription within iOS. So I am stuck at this point. What am I doing wrong, am I setting this all up in the wrong order? Do I need to install some kind of profile or security cert, do I need to give a pint of blood to Imhotep? What am I missing. I even once sat on the phone for 90 minutes with an Apple Support Rep who took me through it step by step, same result. Also I just noticed that inside 'App Store Connect' when you look at the list of 'Sandbox' accounts there is a column for 'Last Purchase' which is entirely blank, apparently after a year of use I have NEVER purchased on the Sandbox, which is another reason I think my subs are going to the main email, not the sandbox one. I tried using the sandbox email as the main account for the whole device, I can't recall the result but it was worse and didn't work at all. So that's not it. https://developer.apple.com/help/app-store-connect/test-in-app-purchases/create-a-sandbox-apple-account/ The instructions on this page are not detailed enough and were not helpful to me. All I really want to know is how to fully setup a real actual iPhone for TestFlight and Sandbox testing of a app. WHat order do I create accounts, validate emails, attach to devices, login with etc etc etc. Step by step, nothing no matter how mundane missed out. A true idiots guide to making this work for me. Testing this on Android always takes 5 mins. iPhone, I'm lucky if I am done in half a day. Please help and thanks for reading!

Testing recurring subscriptions in a new release in both development environment and in Test Flight, we see an increased percentage of failed calls returning from Apple server. The return failure message is that an unknown error occurred. The behavior is not consistent and most often we get a failure and another attempt succeeds. We do get around 50% failures which is alarming and cannot be explained to the end user. We have also experimented with previous test versions that are in production currently and we see the same behavior, so this is not isolated to the most recent release we plan nor to a specific application we have. Past testing in previous releases did not return such high percentage of failures from Apple server. Have you encountered such an issue? We have no idea what may cause Apple server to return with this "Unknown error" and there is no log we can consume from Apple subscription service. Appreciate your help on this.

I just converted my App to Freemium, but the method is used to give user, that bought the App before it was free, access to the paid futures seems not to be working. I am getting the original Purchase Date from the AppTransaction (https://developer.apple.com/documentation/storekit/apptransaction/originalpurchasedate) and comparing that to a set date where the App Model changed. In Test Flight this is working without any Problems but on the Live System, users that have purchased the App do not get access! let shared = try await AppTransaction.refresh() if case .verified(let appTransaction) = shared { result(appTransaction.originalPurchaseDate.ISO8601Format()). } I am using flutter to develop the App and the result()... send the string back to the flutter side. Here is the code of the Flutter side: Future<void> restorePurchases() async { SubscriptionProvider().updatePayment(PurchaseStatus.pending); await InAppPurchase.instance.restorePurchases(); if (Platform.isIOS) { DateTime changedToFreemium = DateTime.utc(2025, 4, 7, 11, 0, 0); String? purchaseDateRaw = await IosFlutterChannel().getOriginalPurchaseDate(); if (kDebugMode) { print("Purchase Date Raw: $purchaseDateRaw"); } if (purchaseDateRaw != null) { DateTime purchaseDate = DateTime.parse(purchaseDateRaw); if (purchaseDate.isBefore(changedToFreemium)) { if (kDebugMode) { print("Restoring legacy purchases"); } SubscriptionProvider().update(true, SubscriptionStatus.active, SubscriptionType.fs_lifetime); } else { if (kDebugMode) { print("Not restoring legacy purchases"); } } } } SubscriptionProvider().updatePayment(PurchaseStatus.purchased); } Console Log when running in Test Environment: flutter: Purchase Date Raw: 2013-08-01T07:00:00Z flutter: Restoring legacy purchases Thanks!

We distribute apps that offer auto-renewing subscriptions. In order to test a new service, we would like to create a new subscription group and subscription product (hereinafter referred to as “test subscription”) for this app. If the “In-app purchase statuses” of the test subscription is “Ready to Submit” is the following behavior correct? ・General end users cannot purchase the test subscription. ・Users with SANDBOX Apple accounts can purchase the test subscription.

We are facing a serious issues with in app purchases in our app. We offer 3 IAP: auto-renewable subscription 1W, auto-renewable subscription 1Y, non-consumable one-time purchase (LifeTime access) In our case 90-95% of transactions fail and we mostly get SKError code=2 . Sometime purchase fails several times for the same user so it’s very hard to believe that user intentionally cancels transaction for the same product 4 or even 5 times in a row. It happens regardless iOS version, device model, our app version. We've checked multiple threads with the same issue but coudn't find any solution. We do not offer any promotions, product identifiers are valid... Some users are able to make a purchases without any issues.

I'm encountering a crash on app launch. The crash is observed in iOS version 17.6 but not in iOS version 18.5. The only new notable thing I added to this app version was migrate to store kit 2. Below is the error message from Xcode: Referenced from: &lt;DCC68597-D1F6-32AA-8635-FB975BD853FE&gt; /private/var/containers/Bundle/Application/6FB3DDE4-6AD5-4778-AD8A-896F99E744E8/callbreak.app/callbreak Expected in: &lt;A0C8B407-0ABF-3C28-A54C-FE8B1D3FA7AC&gt; /usr/lib/swift/libswift_Concurrency.dylib Symbol not found: _$sScIsE4next9isolation7ElementQzSgScA_pSgYi_tYa7FailureQzYKFTu Referenced from: &lt;DCC68597-D1F6-32AA-8635-FB975BD853FE&gt; /private/var/containers/Bundle/Application/6FB3DDE4-6AD5-4778-AD8A-896F99E744E8/callbreak.app/callbreak Expected in: &lt;A0C8B407-0ABF-3C28-A54C-FE8B1D3FA7AC&gt; /usr/lib/swift/libswift_Concurrency.dylib dyld config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/usr/lib/libLogRedirect.dylib:/usr/lib/libBacktraceRecording.dylib:/usr/lib/libMainThreadChecker.dylib:/usr/lib/libRPAC.dylib:/System/Library/PrivateFrameworks/GPUToolsCapture.framework/GPUToolsCapture:/usr/lib/libViewDebuggerSupport.dylib``` and Stack Trace: ```* thread #1, stop reason = signal SIGABRT * frame #0: 0x00000001c73716f8 dyld`__abort_with_payload + 8 frame #1: 0x00000001c737ce34 dyld`abort_with_payload_wrapper_internal + 104 frame #2: 0x00000001c737ce68 dyld`abort_with_payload + 16 frame #3: 0x00000001c7309dd4 dyld`dyld4::halt(char const*, dyld4::StructuredError const*) + 304 frame #4: 0x00000001c73176a8 dyld`dyld4::prepare(...) + 4088 frame #5: 0x00000001c733bef4 dyld`start + 1748``` Note: My app is a Godot App and uses objc static libraries.

I have a rather simple StoreKitSubscriptionView for my app's single subscription. Question: Am I expected to write code to handle lack of network connectivity? When I run the app on development device, not using the local StoreKit configuration but rather the real app store, if the network is not available I get a not-user-friendly error message instead of the normal SubscriptionStoreView content. I'm uncertain if end-users actually see this. Maybe they see a more appropriate "Cannot connect to App Store, try later" message? Maybe I am supposed to check for network and not present the view if it is not available. I don't recall any mention of this in the WWDC video but I guess I should check again. Ideas anyone?

Hi, Currently, instead of using a real device and test account for in-app purchase testing, we are using Products.storekit with the Simulator. Our app offers a subscription plan with a 3-day free trial. We would like to simulate the following test scenarios: User cancels the subscription within the 3-day free trial period. User cancels the subscription after the 3-day free trial period. However, in Xcode, under Debug > StoreKit > Manage Transactions..., we couldn’t find an option to simulate a subscription cancellation. There is an option to refund the purchase, but we believe this is not the same as a cancellation. Do you have any idea how we can simulate these two cases using Products.storekit and the Simulator? Thanks in advance!

I am trying to implement in-app purchases in Apple TV. I added a "non-consumable" product and started testing in Sandbox, but it did not work properly. While I am trying to fetch the product from the appstore, it won't give any responses like success or failure. So that our app gets rejected in the App Store. Please provide me the steps to implement in-app purhcase in Apple tvos using Swift. Note: The same code is working fine in iOS.

Dear Apple Support, We are currently in the process of migrating from Apple Server Notifications v1 to v2. As you know, once we switch from v1 to v2 in App Store Connect, this change is irreversible. Our team needs to ensure that our backend environment, developed in Python with Django and using the app-store-server-library==1.5.0, is fully prepared to handle all possible notification types before making that final switch. While we can receive a basic test notification from Apple, it doesn’t provide the range of data or scenarios (e.g., INITIAL_BUY, RENEWAL, GRACE_PERIOD, etc.) that our code must be able to process, store in our database, and respond to accordingly. Without comprehensive, example-rich raw notification data, we are left guessing the structure and full scope of incoming v2 notifications. Could you please provide us with a set of raw, fully representative notification payloads for every notification type supported in v2? With these examples, we can simulate the entire lifecycle of subscription events, verify our logic, and confidently complete our migration. Thank you very much for your assistance.

We are running auto-renewing subscriptions with StoreKit2 and the “get all subscription statuses” API is behaving unexpectedly. record the originalTransactionId from the iPhone to the server side when purchasing a subscription with Storekit2. query the get all subscription statuses API from the server side with the originalTransactionId recorded. get all subscription statuses returns a response, but there is no data in the response that matches the originalTransactionId. I have an error on my system because I have built my system on the assumption that all subscriptions including originalTransactionId will be returned.
