Hi everybody! I'm desperately looking for help as I'm stuck with a rather fundamental problem regarding StoreKit2 - and maybe Swift Concurrency in general: While renovating several freemium apps I'd like to move from local receipt validation with Receigen / OpenSSL to StoreKit2. These apps are using a dedicated "StoreManager" class which is encapsulating all App Store related operations like fetching products, performing purchases and listening on updates. For this purpose the StoreManager holds an array property with IDs of all purchased products, which is checked when a user invokes a premium function. This array can have various states during the app's life cycle: Immediately after app launch (before the receipt / entitlements are checked) the array is empty After checking the receipt the array holds all (locally registered) purchases Later on it might change if an "Ask to Buy" purchase was approved or a purchase was performed It is important that the array is instantly used in other (Objective-C) classes to reflect the "point in time" state of purchased products - basically acting like a cache: No async calls, completion handler, notification observer etc. When moving to StoreKit2 the same logic applies, but the relevant API calls are (of course) in asynchronous functions: Transaction.updates triggers Transaction.currentEntitlements, which needs to update the array property. But Xcode 16 is raising a strict error because of potential data races when accessing the instance variable from an asynchronous function / actor. What is the way to propagate IDs of purchased products app-wide without requiring every calling function as asynchronous? I'm sure I'm missing a general point with Swift Concurrency: Every example I found was working with call-backs / await, and although this talk of WWDC 2021 is addressing "protecting mutable states" I couldn't apply its outcomes to my problem. What am I missing?

Dear Apple Support Team, Hello! I am currently developing the in-app subscription functionality using Apple IAP API and have encountered a serious technical issue while processing subscription data. I would like to report this issue to you. Issue Description: When calling the subscription API endpoint, the same OriginalTransactionId returns inconsistent results. Specifically, a particular transaction ID (let's call it TransactionId_A) should belong to the subscription order with OriginalTransactionId_A, but it is currently incorrectly associated with OriginalTransactionId_B. This issue severely affects our ability to accurately manage and process subscription data. Here are the relevant log details for your reference: API Endpoint Requested: https://api.storekit.itunes.apple.com/inApps/v1/subscriptions/{TransactionId_A} (Note: The link is a placeholder for the actual API endpoint.) Log Information on February 21, 2025, at 09:40:09: { "AppAccountToken": "{AppAccountToken}", "BundleId": "{BundleId}", "Currency": "CNY", "Environment": "Production", "ExpiresDate": {ExpiresDate}, "InAppOwnershipType": "PURCHASED", "IsUpgraded": false, "OfferDiscountType": "", "OfferIdentifier": "", "OfferType": 0, "OriginalPurchaseDate": {OriginalPurchaseDate}, "OriginalTransactionId": "{OriginalTransactionId_A}", "Price": {Price}, "ProductId": "{ProductId}", "PurchaseDate": {PurchaseDate}, "Quantity": 1, "RevocationDate": 0, "RevocationReason": 0, "SignedDate": {SignedDate}, "Storefront": "CHN", "StorefrontId": {StorefrontId}, "SubscriptionGroupIdentifier": "{SubscriptionGroupIdentifier}", "TransactionId": "{TransactionId_A}", "TransactionReason": "PURCHASE", "Type": "Auto-Renewable Subscription", "WebOrderLineItemId": "{WebOrderLineItemId}" } Log Information on March 21, 2025, at 09:38:49: { "AppAccountToken": "{AppAccountToken}", "BundleId": "{BundleId}", "Currency": "CNY", "Environment": "Production", "ExpiresDate": {ExpiresDate}, "InAppOwnershipType": "PURCHASED", "IsUpgraded": false, "OfferDiscountType": "", "OfferIdentifier": "", "OfferType": 0, "OriginalPurchaseDate": {OriginalPurchaseDate}, "OriginalTransactionId": "{OriginalTransactionId_B}", "Price": {Price}, "ProductId": "{ProductId}", "PurchaseDate": {PurchaseDate}, "Quantity": 1, "RevocationDate": 0, "RevocationReason": 0, "SignedDate": {SignedDate}, "Storefront": "CHN", "StorefrontId": {StorefrontId}, "SubscriptionGroupIdentifier": "{SubscriptionGroupIdentifier}", "TransactionId": "{TransactionId_A}", "TransactionReason": "PURCHASE", "Type": "Auto-Renewable Subscription", "WebOrderLineItemId": "{WebOrderLineItemId}" } From the above logs, it is evident that the same transaction (TransactionId_A) returns different OriginalTransactionId values at different times, which is clearly not expected and severely impacts our ability to correctly process and manage subscription data. I hope you can address and investigate this issue as soon as possible. If you need any further information or assistance, please feel free to contact me. Thank you for your support! Best regards!

I'm developing storekitV2, my app is providing the way to refund some product, and I use method below. func beginRefundRequest(in scene: UIWindowScene) async throws -> Transaction.RefundRequestStatus however when i call the method, the modal view presented but the view shows error with message 'cannot connect'. when I select retry button, something done with indicator and get same result. how can I solve this problem?

Hello, I am encountering an issue where I receive an App Store Server Notification V2 upon the purchase of a consumable item. I have configured the App Store Server Notification V2 endpoint to handle notifications related to subscription products. However, I did not expect to receive notifications for consumable purchases. The notification includes the following signedPayload decoded into the ResponseBodyV2DecodedPayload object with the following values: notificationUUID: 3cd6410b-0c89-4247-aba5-20710e79895e notificationType: null subtype: null The transaction information decoded from the ResponseBodyV2DecodedPayload object is as follows: transactionId: 2000000633622618 webOrderLineItemId: null productId: heart_2 To debug, I called the Get Notification History API of the App Store Server API, and the mentioned notification for the consumable product purchase is not included in the history. Only notifications related to subscription product purchases are retrieved. According to the notification type documentation, there is no explanation for cases where both notificationType and subtype are null, nor is there any mention of receiving notifications for consumable purchases. Therefore, I am uncertain how to interpret and handle this notification. Could you please provide an explanation or guidance on this issue? Thank you.

Our app offers auto-renewable subscriptions using StoreKit Original API for In-App Purchase and App Store Server Notifications V1. Starting around 2025-03-15, we found some cases where original_transaction_id which was associated to web_order_line_item_id of already purchased subscription had changed in the receipt information of verifyReceipt response or App Store Server Notifications V1. The detailed steps are: Around February 2025, re-purchase from the app the same subscription product which was canceled and expired some time ago, using StoreKit Original API for In-App Purchase Receive the following 2 notifications from App Store Server Notifications V1 almost at the same time INITIAL_BUY DID_CHANGE_RENEWAL_STATUS In both notifications, latest_receipt_info contains the receipt for the re-purchased subscription period with new original_transaction_id and web_order_line_item_id pending_renewal_info contains both new original_transaction_id and original one which was generated at first purchase, and original one has "is_in_billing_retry_period": "1" Starting around 2025-03-15, the following happens When we receive another "DID_CHANGE_RENEWAL_STATUS" notification from App Store Server Notifications V1, original_transaction_id which is associated to web_order_line_item_id of the re-purchased subscription period has changed back to the original one (the one which was generated at first purchase) in latest_receipt_info. When we call verifyReceipt with the receipt obtained from appStoreReceiptURL, the response does not seem to contain new original_transaction_id which was generated at re-purchase We have some questions regarding this original_transaction_id behavior. When a user re-purchase the same subscription product which was canceled and expired some time ago, it seems that new original_transaction_id is generated. Is this an expected behavior? If yes, it seems that, at some point, original_transaction_id which is associated to web_order_line_item_id of the re-purchased subscription changed back to the original original_transaction_id which had been generated at first purchase. Is this an expected behavior? What triggers the original_transaction_id change to the original one? Is it related to some user actions or subscription status change?

Hi all, I have a simple prototype subscription for a recurring monthly for $0.29 cheap! And it works great! But it only works great at sub time. It's stuck in the sandbox, constantly giving me "currently subscribed" status even though I’ve done a bunch of things: Force-quit the app. Deleted and re-installed it. Rebooted my phone. Signed out of media purchases. Looked on AppStore connect to try to find anything that seems like it’d let me fix this All efforts in vain. I'm trying to avoid fully logging out of my iCloud account on my phone. Any other thoughts?

Hello, For In App Purchases with a renewable subscription, does the originalTransactionId change in the following scenarios? Case 1: A user subscribes to a subscription A within a Subscription Group SG1. The user then cancels it at the end of the month. Comes back later to subscribe to the same subscription A within the same Subscription Group SG1. Case 2: A user subscribes to a subscription A within a Subscription Group SG1. The user then cancels it at the end of the month. Comes back later to subscribe to subscription B within the same Subscription Group SG1.

I am implementing promotional codes for auto-renewing subscriptions in my app. I need to create the codes and have them link to a discounted auto-renewing subscription. So my normal 1 month subscription is $24.99, I would like to offer users (new subscribers and existing/expired subscribers) the ability to enter a promo code that discounts the price of the first month to $4.99, then $24.99 after the initial first month. All users, regardless of whether or not they have has a previous subscription or not should be able to use this code for this discount. From what I am seeing in documentation, promo codes are only available to users that have had a subscription previously? Currently I am receiving the response "Offer Not Available" with the error: <SKPaymentQueue: 0x2815f0d60>: Payment completed with error: Error Domain=ASDServerErrorDomain Code=3904 "Offer Not Available" UserInfo={NSLocalizedDescription=Offer Not Available I simply do NOT understand why apple engineers have to make something that should be somewhat straightforward, be SO COMPLEX, then when you try to figure out whats going wrong, no meaningful error to troubleshoot. *** I have tried this on users that have had a previous subscription and still the same error.

works perfectly on android but doesn't work at all on IOS and i have used the same bundle id and product ids on both stores. The error that i get on IOS is : "IAP initialization failed: NoProductsAvailable - No Product returned from store" Here are the things that i've done: Created an App ID on the apple developer portal with the correct capabilities I have enabled the correct capabilities on the xcode project Unity Framework is embed and signed, Storekit (do not embed) In singin and capabilities in-app purchases is there I am using testflight to submit the app with a distribution certificate that appears to be valid I've checked the the bundle identifier and it's the same everywhere (unity project, xcode project, App ID) All of the products are cleared for sale and are in the status "ready to submit" I always uninstall the old app version before testing the new one My banking updates are still processing does this effect TestFlight IAP Paid Apps Agreement is in Pending User Info state does this effect also I still haven't filled out the tax forms, so I'm wondering if I need to complete them before my app's in-app purchases (IAPs) work in TestFlight.

While reviewing the Apple Documentation, I came across a potential issue in one of the examples that I believe is worth addressing. The example appears to compare strings instead of integers, which could lead to unexpected behavior in production environments. Specifically, in the line where originalMajorVersion (a string) is compared with newBusinessModelMajorVersion (also a string) using <: if originalMajorVersion < newBusinessModelMajorVersion This comparison performs a lexicographical check rather than evaluating the numerical values of the strings. As a result, strings like "10" would incorrectly be considered less than "2", which is not the desired behaviour when comparing version numbers. I have reported this via the Feedback assistant (FB16432337) but at the time of posting this there has been no reply at all (23 days) Supporting business model changes by using the app transaction do { // Get the appTransaction. let shared = try await AppTransaction.shared if case .verified(let appTransaction) = shared { // Hard-code the major version number in which the app's business model changed. let newBusinessModelMajorVersion = "2" // Get the major version number of the version the customer originally purchased. let versionComponents = appTransaction.originalAppVersion.split(separator: ".") let originalMajorVersion = versionComponents[0] if originalMajorVersion < newBusinessModelMajorVersion { // This customer purchased the app before the business model changed. // Deliver content that they're entitled to based on their app purchase. } else { // This customer purchased the app after the business model changed. } } } catch { // Handle errors. }

Hi 👋! I want to switch the business model in my app from premium to freemium and do it gracefully for existing users. Essentially, I wish to provide newly-paywalled content for free to existing paid users (people who bought the original app). It seems clear that I should be using appTransaction's originalAppVersion property to check against purchases made in a previous version of the app, per the documentation. However, there seems to be broad confusion over whether originalAppVersion returns the version number or the build number and how to test for it. Examples of confusion can be found here, here and here. This lack of clarity seems especially dangerous due to the difficulty in testing these values. In the sandbox originalAppVersion returns 1.0 by default, so whether you design for version number or build number, you'll always return a positive as long as your value is more than 1. There is a real risk to unknowingly either never identify previous premium users or accidentally identify everyone as premium (essentially giving away your app for free). For example, my app's current version number is 1.4.0 and build number is 18, so 1.4.0 (18). As this is a major change, for this new update I might as well go for version number 2.0.0, and let's say I release the app with build number 5, so 2.0.0 (5). If I expect originalAppVersion to return the version number, I would match it against 2, because anything before 2.0.0 needs to be marked as premium. However, if I expect the build number, I should check against 19 and respectively bump up my build number: 5 -> 19. In the standard version/build "v.v.v (b)" format, does originalAppVersion return app version or app build? If it indeed does return build, and not version, I guess I'll start all of my future build numbers from 100 just in case: 2.0.0 (100). The only way I imagine I can test this is to print the value on the visual interface in a live version of the app, and ask a random user 🤷‍♂️.

I have three questions about verify receipt I use this api （https://buy.itunes.apple.com/verifyReceipt）to verify receipt is success or not. But since last month, this interface has started to return an error(21002). I see this document (https://developer.apple.com/documentation/appstorereceipts/verifyreceipt) say its Deprecated. My question is, is the error suddenly returned recently because the interface has been deprecated or for some other reason? (I haven't modified my code about this recently) I can not understand this document: （https://developer.apple.com/documentation/appstorereceipts/validating_receipts_on_the_device） Does this mean that in the new version, as long as the app returns a payment success (purchaseDetails.status == PurchaseStatus.purchased), the payment is guaranteed to be successful, and my server does not need to request payment result verification from Apple's server? I try to use this (https://github.com/apple/app-store-server-library-java) to get TransactionInfo, but I dont konw to get Transaction status to know is success or not. my java server code : AppStoreServerAPIClient client = new AppStoreServerAPIClient(encodedKey, keyId, issuerId, bundleId, environment); TransactionInfoResponse response = client.getTransactionInfo(transactionId); (bug i can note get transaction status, how do i konw this Transaction is success or not)

In my app’s IAP products, before enabling free trials, the App Store Server Notifications V2 callbacks all returned the correct notificationType. For auto-renewable subscriptions, when they were about to expire, the notificationType was either DID_RENEW or EXPIRED. A small number of cases(DID_FAIL_TO_RENEW) failed to renew due to billing issues, which was expected. However, after I enabled a 7-day free trial for the auto-renewable products, I noticed that in the App Store Server Notifications V2 callbacks, almost all users (except those who manually turned off auto-renewal) received notificationType = DID_FAIL_TO_RENEW. According to the documentation, DID_FAIL_TO_RENEW indicates a billing issue renewal failure, but in this case it seems like all renewals are being marked as failed. I’ve observed that for users who cancel during the free trial, the callbacks look normal: first a DID_CHANGE_RENEWAL_STATUS notification, then an EXPIRED notification when the trial ends. That flow seems correct. However, for users who do not cancel the trial, almost all callbacks show DID_FAIL_TO_RENEW. Does this mean every remaining user has a billing issue? I also noticed on the Developer Forums that other developers have reported the same issue — receiving a large number of DID_FAIL_TO_RENEW notifications specifically when free trials convert to paid subscriptions: https://developer.apple.com/forums/search?q=DID_FAIL_TO_RENEW Could someone clarify: under normal circumstances, when a free trial transitions to a paid subscription and fails, should the App Store Server Notifications V2 notificationType indeed be DID_FAIL_TO_RENEW, or should it be a different type(e.g. EXPIRED)? And is it expected behavior that almost all free trial conversions return DID_FAIL_TO_RENEW?

Hello everyone, For example, our app currently has one subscription group in App Store Connect with 5 plans (2 annual, 2 monthly, and 1 quarterly). By default, users can go into Apple Subscriptions in Settings and freely switch between all of these plans. However, our business requirement is to only allow users to stay on one annual plan and one quarterly plan. We don’t want them to switch to the other plans. My questions are: Is there any best practice or recommended approach to restrict subscription switching within the same group? Would removing the unwanted products from sale be the correct approach, or are there any risks/downsides with this method? Has anyone faced a similar situation and found a practical solution? Any guidance or shared experience would be greatly appreciated. Thanks!

I'm using StoreKit together with SubscriptionStoreView to show the subscriptions in my app. I also utilize subscriptionStorePolicyDestination to show the terms of service and the privacy policy link on the view: .subscriptionStorePolicyDestination(url: URL(string: "https://www.apple.com/legal/internet-services/itunes/dev/stdeula/")!, for: .termsOfService). Everything was working fine until iOS 18.0.1. After the update, when you tap into the terms of service (or the privacy policy) link on the store view, it opens the web view by rendering the page incorrectly. Besides that, it is not possible to close the web view anymore, you have to kill the app. I already submitted a bug (FB15552274) on Feedback Assistant but I didn't hear anything back for 2 weeks. My apps are getting rejected now, because the store view doesn't have: A functional link to the Terms of Use (EULA) A functional link to the privacy policy This is really frustrating because the API was working fine but now it is broken and neither the Apple developers nor the reviewers really care if the API is broken.

I’m testing an auto-renewable subscription on TestFlight. Now the user can't re-purchase the same product – Apple just restores the old (expired) one, and no payment sheet appears. How can I let the same TestFlight user re-subscribe to an expired product? Do I have to create a new productId for every test cycle?

I try to call Get Transaction Info from App Store Server API, and the transactionId is for a Non-consumable type product, but it is odd that there are so many different transactionId and they have a same originalTransactionId { "bundleId": "${bundleId}", "environment": "Production", "inAppOwnershipType": "PURCHASED", "originalPurchaseDate": 1691220528000, "originalTransactionId": "${originalTransactionId}", "productId": "${productId}", "purchaseDate": 1691220528000, "quantity": 1, "signedDate": 1692590989925, "storefront": "USA", "storefrontId": "143441", "transactionId": "${originalTransactionId}", "transactionReason": "PURCHASE", "type": "Non-Consumable" } the defination of Non-Consumable is can only purchase once for same apple account. But why there would have originalTransactionId?

Hi. If the app is in landscape only and when the SKStoreProductViewController is presented, the safeArea changes to what looks like a portrait mode safe area. When the SKStoreProductViewController is dismissed, the safeArea does NOT revert back to the original values. Is there a way to force the safeArea to "reset"? I've submitted some bug tickets through Apple Feedback but I haven't received any response about it. The below code will pop up the SKStoreProductViewController and if you have a UIView that is constrained to the safe area, then you can visibly notice that the safe area is changed and doesn't go back. I have tested this on iPhone 14 Pro, iPhone 15, and iPhone 16 Pro and in the Simulators. The incorrect behavior happens on those and probably more. Thanks. #import "ViewController.h" #import &amp;lt;StoreKit/StoreKit.h&amp;gt; @interface ViewController () @property (nonatomic, strong) SKStoreProductViewController *productViewController; @end @implementation ViewController - (IBAction)buttonTapped:(id)sender { self.productViewController = [[SKStoreProductViewController alloc] init]; NSDictionary *parameters = @{ @"id" : @"6443575749" }; [self.productViewController loadProductWithParameters:parameters completionBlock:^(BOOL result, NSError * _Nullable error) { [self presentViewController:self.productViewController animated:YES completion:^{ // presented // The panel that is constraint to the safe area visibly shows that the safe area is no longer correct. }]; }]; } @end

Hi everyone, I was just wondering if anyone could point me in the right direction on how to properly handle inquiries about refunding in-app purchases. I've seen multiple posts saying to direct them to Apple's support, but is there no other direct way of handling this? Also, does Apple not provide an API to interface with so you can issue refunds on behalf of the customer? Thanks.

We have implementend Storekit 2 in our app, for one time purchases and subscriptions, so it is iOS15 and higher only. Everything works fine, but now we want to add App Store promotions for our IAP's. That doesn't work because the App requires the app to implement SKPaymentTransactionObserver How to Promote Your In-App Purchases Make sure your app supports a delegate method in SKPaymentTransactionObserver. You can choose to customize which promoted in-app purchases a user sees on a specific device by implementing SKProductStorePromotionController. The problem is that this observer is part of the original Storekit API and not of the new one. What can we do to make this work with the new Storekit 2 API?
