Is wallet extension an mandatory implementation for Apple Pay and Add to wallet?
I am working on a banking application (includes iPhone and iPad) which includes add to wallet feature. During the implementation I saw one document it is mentioned that for iPad app, the app must be extended to support Apple pay functionality. Details from document says "Card Issuers with an iOS mobile banking app must support Card Issuer iOS Wallet extension functionality to enable Card issuer mobile app customers to provision new cards directly from the iOS Wallet app with all eligible Apple iOS devices. If the Card Issuer has a dedicated iPad App, that App must be extended to support Apple Pay functionality. " Is wallet extension implementation required for Apple pay to work in iPhone and iPad? Is wallet extension a mandatory implementation for Add to Apple Wallet feature to work and approved by Apple? I am little confused in this. Anyone who integrated Apple pay or done add to Apple Wallet feature recently without wallet extension faced any rejection? Any help would be much appreciated.

StoreKit 2.0 keep throwing unknown error.
After the release of StoreKit 2.0, the in-app purchase failure rate increased by 63.19%, with the majority of errors being StoreKitError.unknown. When encountering this error, many users repeatedly attempt to make a purchase, but the outcome remains unchanged, resulting in the same unknown error. In some cases, users who wait approximately 2 minutes before retrying the purchase may either succeed or encounter the following error: “StoreKit.StoreKitError.systemError(Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.storekitd”)”. This issue has directly impacted our app's purchasing flow. Because our app only displays the promotional purchase offer once, these issues have significantly reduced the number of users successfully completing the offer. As a result, the conversion rate for this promotion has dropped well below expectations, negatively impacting our business metrics.

Server Not Receiving Apple App Store Server Notification
Hello, Our server isn't receiving Apple App Store Server Notification for in-app purchases. It works for Sandbox Server, even I sent a test notification which I received on the Production Server URL, but the real in-app payment notification isn't coming to the server. I checked this already: https://developer.apple.com/documentation/appstoreservernotifications/enabling-app-store-server-notifications and everything here has been reviewed. Transport Layer Security (TLS) version and others things mentioned have been checked, test notification was received. But the main in-app purchase notification for live transaction isn't coming. What's the issue precisely?

Best practice to prevent users from switching between subscriptions in the same group?
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!

In iOS 26 beta3 version, the finishTransaction method is unable to remove transactions from the SKPaymentQueue, causing transactions to remain in the queue even after being processed.
We have some users who have upgraded to iOS 26 beta3. Currently, we observe that when these users make in-app purchases, our code calls [[SKPaymentQueue defaultQueue] finishTransaction:transaction]; method, and we clearly receive the successful removal callback in the delegate method - (void)paymentQueue:(SKPaymentQueue *)queue removedTransactions:(NSArray<SKPaymentTransaction *> *)transactions. However, when users click on products with the same productId again, the method - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions still returns information about previously removed transactions, preventing users from making further in-app purchases.

How to change promotional image of in-app purchase
My apps stuck on review stage. Reason of it is Guideline 2.3.2 - Performance - Accurate Metadata We noticed that your promotional image to be displayed on the App Store does not sufficiently represent the associated promoted in-app purchase. Specifically, we found the following issue with your promotional image: – Your promotional image is the same as your app’s icon. The problem is i can't change this image. My subscription is still in 'in review' stage and I don't have option like delete image or change image. I replied to the review explaining that I cannot change it as long as the subscription is under review, but I haven’t received any meaningful reply, except that I need to change promotion image to be eligible for further review(which i cant do because i haven't option to change this image). Has anyone had such a problem before?

In-app purchases fail: "Password reuse" error?
I'm trying to implement my first in-app purchase, and I've created the IAP in App Store Connect, and created a sandbox account. When I open Settings > Developer in the iPhone Simulator, there is a "Sandbox Apple Account" option at the bottom. If I click the blue "Sign In" link I'm asked for the email and password, so I enter the correct credentials for the sandbox account. The "Sign In" text goes grey for a few seconds, then it goes blue again. It never changes to show that I'm signed in. Should it? (I think so.) Do I need to sign into the Simulator's Apple Account, too? (I don't think so.) Anyway, aside from that, in my app the IAP is listed and I have a button to purchase it. When I click it I'm asked for the email and password to sign into the Apple Account. I enter the correct sandbox email and password (they are definitely correct) and I see this in the Xcode console: Purchase did not return a transaction: Error Domain=ASDErrorDomain Code=530 "(null)" UserInfo={client-environment-type=Sandbox, NSUnderlyingError=0x600000d0c7b0 {Error Domain=AMSErrorDomain Code=100 "Authentication Failed The authentication failed." UserInfo={NSMultipleUnderlyingErrorsKey=( "Error Domain=AMSErrorDomain Code=2 \"Password reuse not available for account The account state does not support password reuse.\" UserInfo={NSDebugDescription=Password reuse not available for account The account state does not support password reuse., AMSDescription=Password reuse not available for account, AMSFailureReason=The account state does not support password reuse.}", "Error Domain=AMSErrorDomain Code=0 \"Authentication Failed Encountered an unrecognized authentication failure.\" UserInfo={NSDebugDescription=Authentication Failed Encountered an unrecognized authentication failure., AMSDescription=Authentication Failed, AMSFailureReason=Encountered an unrecognized authentication failure.}" ), AMSDescription=Authentication Failed, NSDebugDescription=Authentication Failed The authentication failed., AMSFailureReason=The authentication failed.}}} Why is it talking about password reuse? AFAIK, I have only one sandbox account for this app (and none for any of my other apps), and this is the only one of my apps that has an IAP. Any ideas on how to get an IAP working? Thanks!

StoreKit.product.purchase returns success, but subscription does not appear in Settings
Description: We are developing an iOS app that offers only one auto-renewable subscription. Recently, a user who had not subscribed for over a year purchased the subscription again through our app. However, when they checked Settings > Subscriptions, the new subscription did not appear. Instead, only their past subscription history was visible, and there was no option to cancel the new subscription. We have verified this issue with a screenshot provided by the user. Additionally, we checked our app’s logs and confirmed that StoreKit.product.purchase successfully returned .success, indicating that the purchase was processed correctly. Code used for purchase: let result = try await product? .purchase(options: [ .appAccountToken(uuid) ]) switch result { case .success(let verificationResult): switch verificationResult { case .verified(let transaction): addPurchaseLog("verificationResult.verified.") case .unverified(_, let verificationError): addPurchaseLog("verificationResult.unverified.") case .userCancelled, .pending, .none: addPurchaseLog("verificationResult.userCancelled or .pending or .none") @unknown default: addPurchaseLog("verificationResult.unknown.") } Despite the successful purchase, the new subscription does not appear under the user's active subscriptions. Could this be a bug in StoreKit? If there are any known issues or workarounds, we would appreciate any guidance. Environment: Xcode: 16.2 iOS version: 16.0+

Xcode 26 beta 3: StoreKit Testing broken
It seems that beta 3 broke StoreKit Testing when running against an iOS 26 simulator device. Specifically, when validating product IDs, the debug console displays messages like the following: [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) In addition, the SKProductsResponse (I am using the original StoreKit API), lists all requested product IDs in invalidProductIdentifiers. The products array is empty. StoreKit Testing behaves as expected when Xcode 26 beta 3 is run against an iOS 18.4 simulator device.

AppTransaction.shared doesn’t return originalAppVersion for users who installed the app in 2017
Hi, I'm using the AppTransaction.shared API to retrieve the originalAppVersion, but I'm encountering issues for users who originally installed the app in 2017. Specifically, the property doesn't seem to return the expected value (or returns nil) for these older accounts. I have verified this issue using a real App Store purchase from 2017. Steps to Reproduce: Use a test account that originally downloaded the app in 2017. Call: let shared = try await AppTransaction.shared print(shared.originalAppVersion) Observe that originalAppVersion is missing or not returned correctly. Any insights on whether this is expected behavior for very old App Store purchases, or if there is a workaround to reliably detect the original app version? Thanks in advance!

iOS promotional code eligibility
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. WTF I have tried this on users that have had a previous subscription and still the same error.

My iOS application cannot connect to the Sandbox environment.
I am testing the subscription flow in my iOS app. Initially, everything was working fine when following the official StoreKit and sandbox testing documentation. After a successful subscription, the “You’re all set” popup always displayed the environment as “sandbox.” However, after some changes, possibly upgrading macOS to the latest version, upgrading Xcode, or regenerating certificates, I can no longer connect to the sandbox testing environment. The subscription success popup now always shows the environment as “xcode.” By default, the iOS app should run in the sandbox on macOS, so I didn’t set the “Enable App Sandbox” option to “Yes” in the Xcode build settings. When I try enabling it, Xcode throws the following error: “Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.n3J0tr/extracted/Payload/XXXX.app : 0xe8008015 (A valid provisioning profile for this executable was not found.) Please ensure that your app is signed by a valid provisioning profile.” Additionally, if “Enable App Sandbox” is set to “No,” the app installs successfully on a real device, but there is no prompt to trust an untrusted developer certificate, which usually appears for such certificates. I’m not sure if this information will be useful to others, but I’ve been stuck on this issue for a while, and it’s preventing me from moving forward with my work. Any help to resolve this would be greatly appreciated. Thank you!

Does originalTransactionId change if a user resubscribes?
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.

Storekit2 equivalent of SKPaymentTransactionObserver
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?

Transaction ID Misassociation in IAP Subscription API
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!
