Operation of Server Notifications V2 when Apple account is withdrawal
Please allow me to confirm the Server Notifications V2 specification. I am aware that if withdrawal an Apple account that has a subscription, the subscription will eventually be cancelled. Regarding Server Notifications V2 notifications with a notificationType of EXPIRED, am I correct in thinking that they will be sent when the subscription expires even if the Apple account is withdrawal?

Unable to sign in to Sandbox Apple Account on Simulator
I am unable to sign in to a Sandbox Apple Account, where this issue occurs only via Simulator. Under Settings > Developer, I tap "Sign In" under Sandbox Apple Account. I enter my account credentials, and after bringing me back to the Developer page, the Sign In button briefly appears as disabled, before being re-enabled, without signing in to the account. (The account credentials are also recognized as correct, as I will receive an alert popup if incorrect.) See screenshots below: After signing in, Sign In button appears disabled... ... then is re-enabled without actually signing in to the account. I have now tried setting up multiple sandbox accounts via App Store Connect with various permutations (no confirmation of Apple Account email, confirming Apple Account email, logging in to iCloud and accepting terms of service), running different device simulators, running simulators on different Mac computers... none of which yield a different result. By contrast, I can sign in to the Sandbox Apple Account without issue on a physical device. The problem occurs only via Simulator.

Can I ask user to share his/her email id while doing
We sell magazines through a third party app platform called Pocketmags and our website. The magazines have Print, Digital and Combo options available for purchase. Also, this third party app provides the platform to read the digital version of the magazines. Once a user buys a subscription on the website, he/she receives the email with the login information on PocketMags, where he registers his login details and can start reading his subscription. With us, the customer shares his billing/shipping address along with their email id while they make payment. Now we have our own app where through which we want to sell these magazines and have to integrate In-App purchase for selling these digital subscriptions. How do we send the 3rd party subscription access details on email to the user if they do in app purchase?

Sandbox user can't see StoreKit subscriptions
Hi everyone, I’m struggling to get StoreKit 2 to fetch products in my SwiftUI app while using a sandbox user. I think I’ve followed all necessary setup steps in Xcode, App Store Connect, and my physical test device, but Product.products(for:) always returns an empty array. I’d appreciate any insights! What I’ve Done Local App Setup (Xcode 16.2) Created a blank SwiftUI Xcode project. Enabled In-App Purchase capability under Signing & Capabilities. Implemented minimal StoreKit 2 code to fetch available products (see below). Using the correct bundle identifier, which matches App Store Connect. App Store Connect Configuration Registered the app with the same bundle identifier. Created an Auto-Renewable Subscription with: Product ID: v1 (matches my code). All fields filled (pricing, localization, etc.). Status: Ready for Review. Linked the subscription to the latest app version in App Store Connect. Sandbox User & Testing Setup Created a sandbox tester account. Logged in with the sandbox user under Settings → Developer → Sandbox Apple ID. This was on my physical device (iOS 18.2). Installed and ran the app directly from Xcode (⌘+R). Issue: StoreKit Returns No Products Product.products(for:) does not return any products. There are no errors thrown, just an empty array. I confirmed that StoreKit Configuration is set to None in Xcode. No StoreKit-related logs appear in the Console. Code Snippets //StoreKitManager.swift import StoreKit import SwiftUI @MainActor class StoreKitManager: ObservableObject { @Published var products: [Product] = [] @Published var errorMessage: String? func fetchProducts() async { do { let productIDs: Set<String> = ["v1"] // Matches App Store Connect let fetchedProducts = try await Product.products(for: productIDs) print(fetchedProducts) // Debug output DispatchQueue.main.async { self.products = fetchedProducts } } catch { DispatchQueue.main.async { self.errorMessage = "Failed to fetch products: \(error.localizedDescription)" } } } } //ContentView.swift import SwiftUI struct ContentView: View { @StateObject private var storeKitManager = StoreKitManager() var body: some View { VStack { if let errorMessage = storeKitManager.errorMessage { Text(errorMessage).foregroundColor(.red) } else if storeKitManager.products.isEmpty { Text("No products available") } else { List(storeKitManager.products, id: \.id) { product in VStack(alignment: .leading) { Text(product.displayName).font(.headline) Text(product.description).font(.subheadline) Text("\(product.price.formatted(.currency(code: product.priceFormatStyle.currencyCode ?? "USD")))") .bold() } } } Button("Fetch Products") { Task { await storeKitManager.fetchProducts() } } } .padding() .onAppear { Task { await storeKitManager.fetchProducts() } } } } #Preview { ContentView() } Additional Information iOS Version: 18.2 Xcode Version: 16.2 macOS Version: 15.3.1 Device: Physical iPhone (not simulator) TestFlight Build: Not used (app is run directly from Xcode) StoreKit Configuration: Set to None

Crash on UIApplicationInvalidInterfaceOrientation when [SKStoreProductViewController shouldAutorotate] is returning YES
I get crash reports which I can't reproduce when trying to present an SKStoreProductViewController : Fatal Exception: UIApplicationInvalidInterfaceOrientation Supported orientations has no common orientation with the application, and [SKStoreProductViewController shouldAutorotate] is returning YES No matter what app Deployment info orientation I try I can't get my SKStoreProductViewController shouldAutorotate property to return YES. It is always false. Does anyone knows why or how to get an SKStoreProductViewController to return shouldAutorotate YES?

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.

The Apple Pay interface is not responding
My server's access to Apple's payment interface (buy. itunes. apple. com/verifiyReceipt) has been unresponsive since the end of March, and I have been searching for a long time without finding any issues. Normally, even if the data is incorrect, there is still a {"status": 21000} response. We are using Alibaba Cloud's virtual servers here. I don't know if Apple has made any adjustments to the interface. If anyone has encountered this problem, please kindly help to answer it. Thank you all.

Reporting to External Purchase Server API when using alternative PSP in the EU
Dear community, Context My company operates in the European Union, where not so long ago there appeared the possibility to accept an ["Alternative Terms Addendum for Apps in the EU"] (https://developer.apple.com/contact/request/download/alternate_eu_terms_addendum.pdf), which, among others, gives us the possibility to use an alternative payment provider, other than Apple's In App Purchase PSP system (ref: Apple docs). My company did accept it and was granted the StoreKit External Purchase Entitlement (com.apple.developer.storekit.external-purchase) entitlement, with which we integrated a different PSP, so now we want to incorporate the reporting to Apple's External Purchase Server API. We are currently integrating with the External Purchase Server API and have encountered a couple of issues I would appreciate clarification on: Question 1 Is there a way to retrieve an overview or summary of the current subscription states on Apple’s servers as a result of the submitted reports to External Purchase Server API? Specifically, I would like to verify the expected outcomes before the monthly invoice is issued by Apple and to understand the subscription states for the test users I used during this process and for future reference as well. Question 2 In one scenario, I initiated a one-year subscription, and in the middle of its period, I submitted a RENEWAL for one month with a higher price. I expected the request to fail due to overlapping periods and/or pricing conflicts, but both submissions were accepted without error. Do you have an idea about: What happens at the end of the renewed month? Will the subscription continue with the renewed (higher) amount, revert to the original (lower) annual rate, or be canceled? Where can I view the final state and billing plan for that subscription? Thank you for your assistance, we are looking forward for any kind of help or information regarding this topic.

Invalid currency symbol
Strange issue with currency display in subscription products Hi everyone, I'm facing a strange issue in my app where I use a subscription-based in-app purchase model. The products I created in App Store Connect are all in "Approved" status. I've tested with both RevenueCat and StoreKit, but the result is the same. Here are the products being loaded: Product loaded: weekly_product_id Display name: Weekly Pro Description: Weekly Pro Subscription Price: ₺229,99 Product loaded: annual_product_id Display name: Annual Pro Description: Annual Pro Subscription Price: ₺1.799,99 Even though I can see the correct prices and currency (Turkish Lira) in the Xcode debug console, on my real device the currency appears as Philippine Peso, as shown in the attached screenshot. Interestingly, in the iOS simulator, it's displayed in USD. I've double-checked and my device's region settings are set to Turkey. Any ideas on what could be causing this? And more importantly, how can I fix it? Thanks in advance!

StoreKit Subscription Fails to Load During App Review, Works in Sandbox/TestFlight
Hi everyone, I’m facing a recurring issue with my macOS app being rejected during App Store review, and I’d really appreciate any guidance. The subscription flow in my app is implemented using StoreKit, and everything works perfectly in our development environment using a StoreKit configuration file. It also behaves as expected in Sandbox testing and TestFlight — I even had few beta testers confirm that the subscription information is displayed correctly and the purchase flow completes without issues. All required subscription details are configured in App Store Connect: • Subscription duration and the description of the services offered • Price and price per unit where applicable • Paid apps agreement and related forms are correctly filled However, when the app is submitted for review, the subscription screen fails to display the expected information. From what I can tell, the product information fails to load from the App Store in the review environment — even though everything is working fine on our side. We’ve already submitted a video to Apple showing the subscription UI working in the Sandbox environment, but the app continues to be rejected under guideline 3.1.2 due to missing subscription info in the binary. Is anyone else experiencing similar behavior during review? Could there be a caching issue or delay in StoreKit syncing for newly configured products? Any help or suggestions are very welcome. Thanks in advance!

Wrong Product.displayPrice?
I am using StoreKit 2 for my products and noticed that users from Ukraine (for example) receive a wrong Product.displayPrice. The App Store works with USD but shows the local currency UAH. Any chance to display the correct currency (USD)?

Error setting install attribution pingback
Hi there, We have an app targeted for children and we want to use the SkAdNetwork to track installs for campaigns. We don't want to track further in-app events (purchase etc.), just the install event. We added the SDK to our Unity app, listed the network identifiers in the plist file, configured the external campaign according to their instructions, but struggle to see any events for several weeks now. We see the following logs in the app: Registering install attribution pingback. Failed to migrate Install Attribution database schema from 17001 => 17400. SkAdNetwork: No pingbacks found while attempting to register/update. Error setting install attribution pingback registered for app: 1509727806, error: Error Domain=ASDErrorDomain code=1208 How can we debug this further? What does the error mean? Thank you very much! (I hope I posted in the correct forum topic. Apologies if not)
