Problem with Family sharing on live build.
Hello, Our app supports family sharing skus, we successfully ran tests on family sharing features in sandbox, we noticed the feature does not work on live builds. The family member (child account) do see the subscription as "Shared with you". We attempted to restore multiple time and there is nothing to restore.

repeat subscription
After the user initiates the subscription payment, the SDK returns an error type: user cancels. When the user initiates the payment again, Apple will deduct the payment twice and successfully deduct the previously cancelled SKU. This is a recent occurrence with a large amount of data, and the app has not been upgraded in any way. We need to seek help. Thank you

How to test about user refund in sandbox?
My server is able to receive notifications for successful purchases. However, we are experiencing an issue where we do not receive any server notifications when a consumable product is refunded. Could you please help us verify if this behavior is expected? Also, is there a way to trigger a test refund notification for consumable products in the sandbox environment, so we can ensure our server is correctly set up to handle it?

StoreKit 2 Sandbox Testing - Product not found
Hi, I've been unable to successfully test in the sandbox environment for a StoreKit 2 subscription group and can't seem to find the missing piece. I am calling the following line of code: let products = try await Product.products(for: [subscriptionID]) Expected behavior: The product is returned in the products array. Actual result: The array is empty I have done the following: Successfully tested our logic using a storekit configuration file locally in Xcode. Created the Subscription group in App Store Connect. The subscription product is currently "Waiting for Review", but it is our first so will not be approved without being attached to a distribution build review. Created a Sandbox user account in App Store Connect -> Users -> Sandbox Signed into the sandbox user account in Settings -> Developer -> Sandbox Apple Account Signed the Paid Apps Agreement for our organization A few debugging notes: I deleted all apps before installing from Xcode I've tried both locally and in TestFlight builds Restarted my device Verified productID matches the productID in App Store Connect I'm not sure if I'm missing something, but any help would be appreciated. Thanks

App crashes on launch due to missing Swift Concurrency symbol
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: <DCC68597-D1F6-32AA-8635-FB975BD853FE> /private/var/containers/Bundle/Application/6FB3DDE4-6AD5-4778-AD8A-896F99E744E8/callbreak.app/callbreak Expected in: <A0C8B407-0ABF-3C28-A54C-FE8B1D3FA7AC> /usr/lib/swift/libswift_Concurrency.dylib Symbol not found: _$sScIsE4next9isolation7ElementQzSgScA_pSgYi_tYa7FailureQzYKFTu Referenced from: <DCC68597-D1F6-32AA-8635-FB975BD853FE> /private/var/containers/Bundle/Application/6FB3DDE4-6AD5-4778-AD8A-896F99E744E8/callbreak.app/callbreak Expected in: <A0C8B407-0ABF-3C28-A54C-FE8B1D3FA7AC> /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 am using swift with bridging headers for interoperability. This issue wasn't observed until my last version in which the migration to storekit2 was the only notable change.

How to Simulate Subscription Cancellation with Products.storekit in Simulator?
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!

Urgent: Reports of Duplicate Charges via AlipayHK on Apple Pay
We’ve recently observed an escalating number of complaints from AlipayHK users regarding duplicate charges when completing transactions via Apple Pay. While no similar issues have been reported by users of other credit card providers integrated with Apple Pay, the problem appears isolated to AlipayHK transactions. Key Details: Multiple users confirm being charged twice for single transactions. Complaints are increasing in frequency, indicating a potential systemic issue. No overlapping reports from non-AlipayHK payment methods at this time. To safeguard customer trust and ensure seamless payment experiences, we kindly request Apple’s support in: Investigating whether the root cause stems from Apple Pay’s transaction handling. Collaborating with AlipayHK (if necessary) to resolve the issue promptly. Providing guidance on interim measures to prevent further duplicate charges. Could Apple confirm if this is a known issue and share a timeline for resolution? We’re eager to assist in any way possible to mitigate impact on users. Thank you for your urgent attention to this matter.

Validating receipt for iOS in-app purchase always returns error 21002
I'm receiving the following error when attempting to validate an in‑app purchase receipt: Certificate verification failed at depth 0 : forge.pki.UnknownCertificateAuthority Certificate chain validation failed: Certificate is not trusted. This error occurs during the certificate chain validation process of the receipt's PKCS#7 container. My implementation uses node‑forge to decode the receipt, extract the embedded certificate chain, and verify that the chain properly links from the leaf certificate (which directly signed the receipt) through the intermediate certificate to the trusted Apple Inc. Root certificate. What the Error Indicates: "UnknownCertificateAuthority" at depth 0: This suggests that the leaf certificate in the receipt is not being recognized as part of a valid chain because it cannot be linked back to a trusted root in my CA store. "Certificate chain validation failed: Certificate is not trusted": This means that the entire certificate chain does not chain up to a trusted certificate authority (in this case, the Apple Inc. Root certificate) as expected. Steps Taken: I verified that the receipt is a valid PKCS#7 container. I extracted the certificate chain from the receipt. However, the receipt only provided the leaf certificate. I manually added the intermediate certificate (AppleWWDRCAG5.pem) to complete the chain. I loaded the official Apple Inc. Root certificate (AppleIncRootCertificate.pem) into my CA store. Despite these steps, the validation still fails at depth 0, indicating that the leaf certificate is not recognized as being issued by a trusted authority. Request for Assistance: Could you please help clarify the following points: Is the certificate chain for receipts (leaf → intermediate → Apple Inc. Root) as expected, or has there been any change in the chain that I should account for? Is there a recommended or updated intermediate certificate I should be using for receipt validation? Are there known issues or recent changes on Apple's side that might cause the leaf certificate to not be recognized as part of a valid chain? Any guidance to resolve this certificate chain validation error would be greatly appreciated.

Inquiry regarding StoreKit Messages for Free Trial Conversion and Recurring Payment Consent in South Korea
Dear Apple Developer Support, Our iOS application offers subscriptions with a free trial period. We understand that in South Korea, due to local subscription regulations, users must explicitly provide consent for recurring payments before the subscription converts from a free trial to a paid period. We have the following questions regarding how StoreKit handles this scenario: When a free trial is about to convert to a paid subscription for a user in South Korea, does StoreKit send a StoreKit.Message (or SKStorefront.Message) to the application to obtain the required consent for recurring payments? If such a message is sent, would the Reason for this message be StoreKit.Message.Reason.priceIncreaseConsent, or would it be another specific reason related to initial recurring payment consent after a trial? If our application receives such a message and we choose to defer its display, what is the maximum recommended or permissible deferral period? Is it possible to save the data of a received StoreKit.Message and display it to the user at a later time, for instance, after the application has been closed and subsequently reopened? Are there any best practices or limitations regarding this? We need this information to ensure our application correctly handles these consent requirements in compliance with South Korean policies and provides a smooth user experience. Thank you for your guidance.

IAP working in StoreKitTest on XCODE but not in TestFlight – shows mapped error "Product not available"
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
