sandbox account isn't logging in on purchase window
I don't know if I am posting this in the right place. I am using xcode's phone simulator and I have setup my sandbox account on appstoreconnect under users and access/sandbox/test accounts then in my app on the simulator when I tap the subscribe button to purchase my product the a window pops up for in app purchases and I get a login prompt for my sandbox credentials, but no matter how many times I enter them after tapping ok all I get is a blank login prompt. also not this a brand new sandbox account and I've only changed the password 3 times, that seems to be important because its inconsistent with some of the errors I am getting on the error log here is error log. Purchase did not return a transaction: Error Domain=ASDErrorDomain Code=530 "(null)" UserInfo={NSUnderlyingError=0x600000d09080 {Error Domain=AMSErrorDomain Code=100 "Authentication Failed The authentication failed."

Age Assurance Sandbox Testing - revoke vs declined
1)What's the relationship between ""Texas, child, 16-17, significant change declined" from my 11:03 screenshot below and "revoking"? ie what situation could someone decline but not revoke or vice versa, what is the purpose of the distinction in testing or legally or implications/implementation 2) What is a cause besides a typo to receive the "Can't trigger notification" titled message after using "Revoke"? you can see by my screenshot by comparing the left and right half there is no title. 3) Even if i find a workaround perhaps my info will help someone else or be an opportunity for improved documentation see: see my 5:54pm second screenshot

InApp purchases ok and ko at the same time (?!)
I'm working on an app the has implemented inapp purchases. They have been working so far, and they keep working currently. But just a couple of days ago, a specific user sent us a support ticket stating that when he purchases and item the bank charges it for the purchase, but within the app, the purchase fails and he doesn't receive the item. He sent us screenshots showing: The iOS native modal when a purchases has been finished correctly ("You're all set - Your purchase was successful "). Right after that modal, the app shows an internal modal showing "The purchase failed, please, try again later". Checking the app logs, that failure modal was triggered by "The operation couldn’t be completed. (StoreKit.StoreKitError error 1.)". Reading docs about this error leads me to think about device or user restrictions (parental controls, usage limits, etc...). It seems that in theses cases the bank charge could be issued but refunded later once Apple ultimately declines the purchase. However the user says that he doesn't have any kind of restriction. The only related thing is a "this device is also restricted by a profile" message, but everyone seems to have this message. What could it be causing this issue? In what scenariowould the app show a native OK modal but a storekit error 1? I'm pretty sure the app is well configured because I keep receiving purchases of all kind, from different users with any problem.

Dev Defined IAP Transaction Metadata
I have an app that works by being able to map IAP transactions to a predefined user ID. This means when I consume events from Apple's App Store Server Notifications endpoints I have to do a reverse lookup in order to assign permissions within my app. Workflow: User purchases subscription within the app via IAP. The app persists the subscriptionID from the Apple IAP library in my cloud database (Firestore). Cloud function receives the event from App Store Server Notifications endpoint and looks up the user ID containing the persisted transactionID (with retries to avoid race condition). Question: This workflow works but it seems an improvement would be to allow dev's to append metadata, like the user ID, to the transaction submitted to IAP that we can access within the signedTransactionInfo of the event from the App Store Server Notifications endpoint in order to facilitate a direct lookup of the user document needing it's permissions updated. This would greatly simplify workflows that use non-Apple systems as a source of truth for app permissions. Does this actually exist already? If not, is there a feature request platform?

Double-counted consumable in StoreKit unfinished and updates workflow
In Getting started with In-App Purchase using StoreKit views and the corresponding sample project, Store simultaneously enumerates Transaction.unfinished and Transaction.updates. Since, "if your app has unfinished transactions, the updates listener receives them once, immediately after the app launches," it appears that Transaction.unfinished would also receive the same unfinished transactions causing handle(updatedTransaction:) to be called for twice for each transaction, causing consumables to be double-counted. Is this a bug in the sample? Is there more information on concurrent execution of unfinished and updates?

Apple ID Password Is Required During In-App Purchase
Hello, I would like to ask about an Apple ID authentication behavior during in-app purchases. Our app uses a StoreKit 1 (SKPaymentQueue-based) implementation, and there are no differences in the in-app purchase logic between the TestFlight build and the App Store production build. However, we have observed that some users are prompted to enter their Apple ID password during in-app purchases. The observed behavior is as follows: On the first in-app purchase, the system prompts for the Apple ID password After the password is entered once, subsequent purchases proceed normally using Face ID (double side-button press) Even after deleting and reinstalling the app, or switching between TestFlight and App Store builds, the password prompt does not reappear if authentication has already occurred This behavior can occur even when the Apple ID already has an active auto-renewable subscription The only confirmed change on our side is: The app is now built with Xcode 26 instead of Xcode 18 Based on this, we are currently considering the following possible causes: A change in purchase authentication behavior due to the Xcode version update Expiration of the Apple ID purchase authentication session after a long period without purchases In addition to these points, we would like to ask: Are there any other common conditions or security policies in iOS or the App Store that may cause the system to require Apple ID password input during in-app purchases? Is this behavior considered expected under certain circumstances? We would appreciate your clarification on whether this is expected system behavior or if there are any implementation aspects we should further review. Thank you for your support.

StoreKit Product Request Times Out in TestFlight (macOS) Despite Successful Server Connection
Product Timeout, In App purchase is approved in App Store Connect. The Product ID and Bundle ID match. Environment macOS App in TestFlight Bundle ID: com.streamtime.StreamTime App Version: 1.1 (Build 51) StoreKit 2 Product ID: com.streamtime.premium Status: App & Subscription Approved Issue StoreKit product request (Product.products(for:)) consistently times out after 60 seconds in TestFlight, despite all connectivity checks passing. The same code works perfectly in Xcode with local StoreKit configuration. Diagnostic Results ✅ Successful checks: App Store connectivity (HTTP 200 from buy.itunes.apple.com) Backend API connectivity (HTTP 200) StoreKit 2 API available AppStore.canMakePayments: true Valid receipt exists Bundle ID matches Product ID matches approved subscription ❌ Failing: Product request times out after 60 seconds No products returned Code Implementation // Direct product request (fails in TestFlight) let products = try await Product.products(for: ["com.streamtime.premium"]) Logs 🔍 App Bundle ID: com.streamtime.StreamTime 🔍 Product ID: com.streamtime.premium 🔍 AppStore.canMakePayments: true 🔍 Apple Store connectivity: HTTP 200 🔵 Direct request for product ID: 'com.streamtime.premium' ⏱️ Direct request start time: 2025-08-30 10:21:32 +0000 ❌ TIMEOUT: Product request took longer than 60 seconds What I've Tried Removed manual in-app-purchase entitlement (per Apple's guidance) Using automatic signing Verified subscription is approved in App Store Connect Using Sandbox Apple ID in TestFlight Verified all network connectivity Questions Why does StoreKit timeout only in TestFlight when all other connectivity works? Are there additional configuration steps needed for macOS apps vs iOS? Could this be related to the automatic in-app purchase entitlement? Any guidance would be greatly appreciated as this is blocking our TestFlight validation.

An unrecognised subscription
Hello, I have a problem with a subscription: it is not recognised by my application (under TestFlight); it is as if it did not exist. I have two subscriptions in the same group, a premium subscription that works perfectly and a basic subscription that is not recognised. I have checked everything at least twenty times. Its status is ‘Ready to submit’. I asked GPT 5.1 and Claude AI, but clearly both of their AIs are out of date and are giving me an obsolete procedure with App Store Connect options that don't exist.

How to test refunds of consumable purchases?
I have consumable IAPs in my app. Currently there is no way for me to test refunds for them as Xcode testing doesn't allow refunds option for my Purchases. According to this official documentation on Transaction.all , i should be getting my refunded consumables in Transaction's all property. But there is no way for me to know what kind of data is in the refunded transaction object. Will there be a 'revocation date' like in the case of non-consumables?

AppDistributor.current never returning
I try to access the AppDistributor.current (using try await) and the property never seem to return nor throw. The code I'm using looks like this: do { print("accessing current") let current = try await AppDistributor.current print("current obtained") switch(current) { case .appStore: return "AppStore" default: return "Unknown" } } catch { return "Exception: \(error)" } But the log only shows the accessing current and never the current obtained. Trying to step in the property starts with some assembly, but at some point, the debugger just never returned. I join a full Swift file of a sample test I'm using: SwiftMarketplaceTests.swift

Mismatch between App Store Server API `expiresDate` (July 23) and iOS UI “Expires on” date (July 22) for 1-month subscription
Hi everyone, I’m seeing a consistent one-day discrepancy between the expiresDate returned by the App Store Server API and the “Expires on” date shown in the iOS Settings / App Store subscription list. I’d like to confirm whether this behavior is expected or if I’m misunderstanding the way Apple rounds dates. Reproduction steps Step Action Result 1 Purchase a 1-month auto-renewable subscription on 23 June 2025 14:00 JST (UTC+9) Transaction succeeds 2 Immediately fetch the transaction with GET /inApps/v1/subscriptions/{transactionId} Response contains "expiresDate": "2025-07-23T05:00:00Z" (= 23 July 2025 14:00 JST) 3 On the same device open Settings › Apple ID › Subscriptions (or App Store › Account › Subscriptions) UI shows Expires on: 22 July 2025 The same happens for every monthly renewal and on multiple devices. Region is Japan, device time zone Asia/Tokyo. What I understand so far (and my hypothesis) Apple’s docs say a monthly subscription renews “on the same calendar date” of the next month, so renewal in this example is 23 July. If the renewal is scheduled for 23 July at 14:00 JST, the subscription is fully usable until the end of 22 July in calendar terms, because the new billing period starts the moment the 23rd begins in Apple’s canonical time zone. Therefore, it might be intentional for the UI to display 22 July—i.e., “you can keep using it through the 22nd; on the 23rd it renews.” This hypothesis makes sense internally, yet it still looks confusing to end users who read “Expires on 22 July” and assume access ends at 00:00 on the 22nd, a whole day earlier than in reality. Questions Is showing the day before the renewal date the official/expected behavior? If so, could Apple clarify that the “Expires on” label represents the last full calendar day rather than the exact expiry timestamp? Which value should we surface in-app when telling users “Your subscription is valid until …”? The server’s expiresDate (precise to the second, converted to user time zone), or A UI-style date that’s one day earlier, matching Settings / App Store? Does Apple have a public document describing this rounding/visual convention? Have other developers encountered user confusion about the apparent 1-day “shortening” and, if so, how did you word your in-app messaging? Any insight from Apple engineers or fellow developers would be greatly appreciated. Thank you!

How to check if user still have valid subscription?
Is there an API Endpoint that I can call to check if user still have valid subscription? I want to be sure that his subscription renewal was succesful (ie: I dont want to give him another month/year/.. if his latest renewal wasnt successful) Would GET https://api.storekit.itunes.apple.com/inApps/v1/transactions/{transactionId} be the correct API endpoint to call? But I wonder, after subscription auto-renews, do we still use the same transactionId to check whether his subs is still valid?

Cannot see support instruction pages or entitlement request page for external purchase links.
Hello! I am trying to get my app set up to support external payments. The snag I am hitting at the moment is it seems that relevant pages are not accessible? There is this old EU doc https://developer.apple.com/support/apps-using-alternative-payment-providers-in-the-eu/ But the more updated US doc titled "Distributing apps in the U.S. that provide an external purchase link - Support" is not available where it should be https://developer.apple.com/support/storekit-external-entitlement-us/ In addition the link for requesting the entitlement seems to be broken https://developer.apple.com/contact/request/storekit-external-entitlement-us/ Any idea how one can access these? Perhaps this is just a temporary error?

Ask to buy pending state lacking transaction object
StoreKit ask to buy should have more data in pending state. When user try to purchase ask to buy, we should get at least transactionID, product itself, and time that user start the request. So we can keep track of the whole transaction flow jwsRepresentation should always available for every state, actually even failing state. And should attach state inside of it. Instead of only available after verified purchase. So we can use transactionID and everything relate to transaction for both waiting for purchase and clearing up the cancel or invalid purchase Currently we only have jwsRepresentation after complete purchase, which is very limited its usage

Screen Rocorder plus Front Camera
I want to build an app for ios using react native. preferably expo. The app will be for recording user experiences with technology. the SLUDGE that they face while navigating through technology. I want to have basic login, signup. The main feature would be to have 2 recording modes. First is record the screen and the front camera simultaneously. Second is to record the back camera and the front camera simultaneously. I can then patch the two outputs later on that is the screen recording and the front camera clip in post processing. I want to know if this is possible as I was told that react native and expo does not have the support yet. if not is there any library or another approach to make this app come alive.

Cannot get public keys for jwks verification
I am using the public url https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/jwsPublicKeys to get the jwks keys to verify the signed payload for store kit payments. I am checking Apple server notifications. const APPLE_JWKS_URL = "https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/jwsPublicKeys" // Apple JWK set (cached by jose) const appleJWKS = createRemoteJWKSet(new URL(APPLE_JWKS_URL)); const jwks = await appleJWKS(); logger.debug("Apple JWKS Keys: %O", jwks); // Log the keys if (!signedPayload) { // return res.status(400).json({ error: "Missing signedPayload" }); } // Step 1: Verify JWS (signature + payload) using Apple's JWKS const { payload, protectedHeader } = await jwtVerify( signedPayload, appleJWKS, { algorithms: ["ES256"], // Apple uses ES256 for signing } );

Request Guidance on IAP Requirements for Dynamically Priced Digital Video Content
Dear Apple Developer Support Team, I hope you are doing well. We are reaching out to request clarification and guidance regarding the In-App Purchase (IAP) requirements for our upcoming iOS application. Our app offers paid access to digital video content. Each video has a dynamic price determined by our backend based on multiple factors (such as duration, category, and promotions). Additionally, users are allowed to select and purchase multiple videos at the same time, which results in a combined total price that varies per transaction. Challenges we face with IAP on iOS Dynamic pricing: Apple requires IAP products to have static pricing defined in App Store Connect. Our video prices change frequently and cannot be represented by fixed IAP product SKUs. Multiple-item purchases: iOS does not support a single purchase that includes multiple different IAP products. Processing many separate IAP transactions in sequence results in a poor user experience and is likely to cause failures. Product creation limitations: Since our catalog contains many videos with frequently changing prices, it is not feasible to create individual IAP products per video. Given these restrictions, we are unclear how to remain compliant while still providing a functional purchase flow for our users. Question In this scenario, where: video prices are dynamic, users may purchase multiple videos together, and IAP does not support multi-item purchases or dynamic pricing, are we allowed to use Stripe or another external payment provider to handle these purchases? If not, we would appreciate Apple’s guidance on what the recommended and compliant approach would be for apps that must price digital content dynamically and allow bulk purchasing. We want to ensure full compliance with App Store Review Guidelines and would like confirmation on the correct implementation strategy before proceeding. Thank you for your time, and we look forward to your clarification. Kind regards, Muhammad Adnan Koderlabs
