Account Locked

Problem Description: 1、I have two sandbox accounts from different countries. Account A is from Mainland China (CHN), and Account B is from the United States (USA). When I switch the sandbox account from Account A (CHN) to Account B (USA) in the system settings and restart the app, the value of SKPaymentQueue.defaultQueue.storefront.countryCode always returns CHN instead of the expected USA. 2、This issue only occurs on iOS 18.2 and above. 3、On the same device running iOS 17.5.1, the behavior is correct. However, after upgrading the system to iOS 18.3.2, the error occurs. 4、In the sandbox environment, although SKStorefront.countryCode returns the wrong value, the currency type for Apple's in-app purchase is correct when initiating the payment. 5、The issue only exists in the sandbox environment and does not occur in the App Store-downloaded package. Demo Code: - (IBAction)clickButton:(id)sender { NSString *appStoreCountryCode3 = SKPaymentQueue.defaultQueue.st

Hello, I was trying to test out Foundation Model however it says Model assets are unavailable. I got my MacBook M1 back in China when i was living there. is this due to region lock?

Hi Apple Devs, We are having trouble getting subscription purchases to work in sandbox. We have sandbox set up with the right account and configuration, but the first subscription we submitted is still pending review. It seems that we cannot test the purchase flow until it has actually been approved. That is, attempting to upgrade your subscription leads to an invalid product ID error, presumably because the product is not ready for sale. Am I misunderstanding how subscriptions are supposed to be tested and reviewed? Thank you!

What’s the recommended way to recursively walk through a directory tree using File Coordination? From what I understand, coordinating a read of a directory only performs a “shallow” lock; this would mean that I’d need to implement the recursive walk myself rather than use FileManager.enumerator(at:includingPropertiesForKeys:options:errorHandler:) plus a single NSFileCoordinator.coordinate(with:queue:byAccessor:) call. I’m trying to extract information from all files of a particular type, so I think using NSFileCoordinator.ReadingOptions.immediatelyAvailableMetadataOnly on each file before acquiring a full read lock on it (if it’s the right file type) would make sense. Am I on the right track?

Hi there, We’re testing Declarative Device Management (DDM) for VPP app management and followed the latest declaration template here: https://github.com/apple/device-management/blob/release/declarative/declarations/configurations/app.managed.yaml Our goal is to enable VPP auto-updates via the declaration. The payload we’re using looks like this: AppStoreID: 1231325957, InstallBehavior: {Install: Required, License: {Assignment: Device}}, UpdateBehavior: {AutomaticAppUpdates: AlwaysOn} } What we’re seeing Device A (no Apple ID signed into App Store): User can manually update the VPP app with the above declaration in place. ( The same user cannot update the app if UpdateBehavior is not in the declaration payload. Device B (Apple ID signed into App Store, and the same Apple ID doesn't have the above app purchased): User cannot manually update the same VPP app. The App Store shows the error seen when UpdateBehavior is absent: “ cannot be updated because it was refunded or purchased with a different Apple Account

I'm trying to sign-in with a Sandbox account with my iOS simulator. Using Xcode 26 beta 7. After I sign in, the button goes inactive for a few seconds but then nothing happens. It does not actually sign me in.

Hello everyone, We recently transferred our iOS app from one Apple Developer account to another, and after the transfer, we encountered a serious issue where all previously stored Keychain data and the local database became inaccessible. As a result, all users are automatically logged out and lose access to their locally stored data (such as chat history) once they update to the new version signed with the new Team ID. We understand that Keychain items are tied to the App ID prefix (Team ID), which changes during an app transfer. However, we’re looking for possible workarounds or best practices to avoid user data loss. Questions: Is there any reliable method to maintain or migrate access to old Keychain data after an app transfer? Would reverting the app back to the original developer account and releasing an update from there (to persist or migrate data) before transferring it again be a viable solution? Has anyone faced a similar issue and found a practical way to handle data persistence d

Description: I’m integrating Apple Pay JS (version 3) into an Angular application. Here are the key details: Environment: Angular (latest) Apple Pay JS v3 Chrome (confirmed window.ApplePaySession is available) application region is in US. I'm in Taiwan and using my iPhone Taiwan account to scan the QR Code/ Implemented Handlers: onvalidatemerchant onpaymentmethodselected onpaymentauthorized oncancel Observed Behavior: When I click the Apple Pay button, the console logs: Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://applepay.cdn-apple.com') does not match the recipient window's origin ('https://{our-domain-name}') Despite this, the QR code still appears. Scanning the QR code with an iPhone 13 Pro running iOS 18.4.1 brings up the Apple Pay sheet with the correct amount, but payment never completes. In the browser, none of my Angular event handlers fire except oncancel. Questions: What causes the postMessage origin mismatch with Apple’s CDN frame, and how should my
