I'm trying to understand the terminology around forward vs backward references in CloudKit. Say I have two record types: User LeaderboardScore (a score belongs to a user) The score record stores a user reference: score["user"] = CKRecord.Reference( recordID: userRecordID, action: .deleteSelf ) So: LeaderboardScore → User The user record does not store any references to scores From a data-model perspective: Is this considered a forward reference (child → parent)? Or a back reference, since the score is "pointing back" to its owner? My use case is having leaderboard in my app and so i have created a user table to store all the users and a score table for saving the scores of each user of the app.

Hi! My users have reported (and I have observed) a blank Live Activity where only a black capsule is shown in the dynamic island. When tapping that capsule, the app opens, but inside the capsule, nothing is shown. The Live Activity is created through the AlarmKit API like this: let identifier = UUID() Task { do { _ = try await AlarmManager.shared.schedule( id: identifier, configuration: .init( countdownDuration: countdownDuration, attributes: attributes, stopIntent: CancelTimerIntent(), secondaryIntent: RestartTimerIntent(), sound: Settings.shared.systemAlarmToneEnabled ? .default : .named(Settings.shared.alarmTone[.loop].filename) ) ) Log.debug("Alarm scheduled successfully: \(identifier.uuidString)") } catch { Log.error("Error scheduling alarm with id \(identifier.uuidString), error: \(error)") } } I've read some other forum posts where developers reported the same issue: https://developer.apple.com/forums/thread/807335 https://developer.apple.com/forums/thread/812006 I assume, it has something to do with state management. However, in my case, this only happens very rarely. I use the app on a daily basis and the issue with the blank live activity only occurs like once a month, so I cannot reproduce it. I also have some logic to resume an existing alarm or snooze: do { for alarm in try AlarmManager.shared.alarms { switch alarm.state { case .paused: try AlarmManager.shared.resume(id: alarm.id) case .alerting: try AlarmManager.shared.countdown(id: alarm.id) default: break } } } catch { Log.error("Error resuming alarm: \(error)") } Is there any way I can debug this issue properly? I have checked the Device Logs and the Console in Xcode and didn't find any hints. Only one log made me a little suspicious, but I read that this might happen occasionally and may be ignored: Couldn't read values in CFPrefsPlistSource<0x10ae0d080> (Domain: group.myappgroupidentifier User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd Any ideas on how I could proceed to find the cause of this empty (apparently crashed) Live Activity?

I use MapKit and MKDirections for driving directions. The error "Directions Not Available" appears when the two points (A and B) are outside mainland China (e.g. Tokyo → Osaka). For routes inside China (e.g. Shanghai → Beijing), the same code works. let req = MKDirections.Request() req.source = MKMapItem(placemark: MKPlacemark(coordinate: origin)) req.destination = MKMapItem(placemark: MKPlacemark(coordinate: destination)) req.transportType = .automobile MKDirections(request: req).calculate { response, error in // Tokyo–Osaka (outside China): "Directions Not Available" // Shanghai–Beijing (inside China): works } Questions: Is MKDirections intended to support only routes within the device’s region (e.g. China)? When A/B are abroad, is "Directions Not Available" expected? Is this documented? For cross-country or overseas routes (e.g. Tokyo–Osaka), what is the recommended approach—third-party routing API + drawing on MapKit? Thanks.

I’m encountering a persistent issue with my Network Extension (specifically NEFilterDataProvider) and would really appreciate any insights. The extension generally works as expected, but after some time — especially after sleep/wake cycles or network changes — a global network outage occurs. During this state, no network traffic works: pings fail, browsers can’t load pages, etc. As soon as I stop the extension (by disabling it in System Preferences), the network immediately recovers. If I re-enable it, the outage returns instantly. I’ve also noticed that once this happens, the extension stops receiving callbacks like handleNewFlow(), and reinstalling the app or restarting the extension doesn’t help. The only thing that resolves the issue is rebooting the system. After reboot, the extension works fine again — until the problem reoccurs later. I asked AI about this behavior, and it suggested the possibility that the kernel might have marked the extension as untrusted, causing the system to intentionally block all network traffic as a safety mechanism. Has anyone experienced similar behavior with NEFilterDataProvider? Could there be a way to detect or prevent this state without rebooting? Is there any logging or diagnostic data I should collect when it happens again? Any guidance or pointers would be greatly appreciated. Thanks in advance!

Hi, I’m implementing ePassport reading in an iOS app using a third-party KYC identity verification SDK (the SDK handles the NFC logic internally). Before adding any specific AID, the NFC session would start normally and iOS showed the system popup asking the user to hold the passport near the device. However, the passport was never read , the session just stayed there with no progress or data returned. I then tried enabling the ICAO ePassport AID: A0000002471001 After adding this, the build failed with the following signing error: Provisioning profile "iOS Team Provisioning Profile: com.sandrotbilisi.DigitalCurrency" doesn't include the com.apple.developer.nfc.readersession.iso7816.select-identifiers entitlement. Has anyone encountered this behavior when working with ePassports? Do I need special entitlement approval from Apple for this AID? Thank you.

Hi, I’m building an iOS self accountability app using FamilyControls and DeviceActivity. I can show the user’s real Screen Time correctly inside a DeviceActivityReport extension on a real device, but I want to use that same daily total inside the main app for today’s log and leaderboard. What I’m stuck on is getting that value back into the app. I tried App Groups, shared UserDefaults, a shared file in the app group container, and CFPreferences, but the report still only works as a display and the main app never receives the total. Is there any Apple supported way to use the daily Screen Time total from a DeviceActivityReport extension inside the containing app, or is this intentionally display only? Thanks.

Hi - Using storekit2 on ios26.2 and using presentOfferCodeRedeemSheet to allow users to leverage Offer Codes. The codes work (sandbox and production), however on the confirmation view that shows Redeem Special Offer, while my App Icon is properly displayed up top, the associated product subscription image is missing and I see a grey App Store image/icon instead. I do successfully see the associated subscription and pricing to the right. My subscription product images are already reviewed/approved and have been live for a number of weeks. I see this in Sandbox and Production (with a live customer sending me the phone screenshot). PS, my product icons/logos all show up successfully during normal checkout in sandbox/production, this only occurs on Offer Code Redemption views.

I have a driver extending IOUserUSBSerial and I want the device to show up as /dev/tty.mycustombasename-123 and /dev/cu. respectively. How can I achieve that?

I am writing a DriverKit driver for the first that uses the USBSerialDriverKit. The driver its purpose is to expose the device as serial interface (/dev/cu.tetra-pei0 or something like this). My problem: I don't see any logs from that driver in the console and I tried like 40 different approaches and checked everything. The last message I see is that the driver get successfully added to the system it is in the list of active and enabled system driver extensions but when I plug the device in none of my logs appear and it doesn't show up in ioreg. So without my driver the target device looks like this: +-o TETRA PEI interface@02120000 <class IOUSBHostDevice, id 0x10000297d, registered, matched, active, busy 0 (13 ms), retain 30> | { | "sessionID" = 268696051410 | "USBSpeed" = 3 | "UsbLinkSpeed" = 480000000 | "idProduct" = 36886 | "iManufacturer" = 1 | "bDeviceClass" = 0 | "IOPowerManagement" = {"PowerOverrideOn"=Yes,"DevicePowerState"=2,"CurrentPowerState"=2,"CapabilityFlags"=32768,"MaxPowerState"=2,"DriverPowerState"=0} | "bcdDevice" = 9238 | "bMaxPacketSize0" = 64 | "iProduct" = 2 | "iSerialNumber" = 0 | "bNumConfigurations" = 1 | "UsbDeviceSignature" = <ad0c16901624000000ff0000> | "USB Product Name" = "TETRA PEI interface" | "locationID" = 34734080 | "bDeviceSubClass" = 0 | "bcdUSB" = 512 | "USB Address" = 6 | "kUSBCurrentConfiguration" = 1 | "IOCFPlugInTypes" = {"9dc7b780-9ec0-11d4-a54f-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"} | "UsbPowerSinkAllocation" = 500 | "bDeviceProtocol" = 0 | "USBPortType" = 0 | "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb")) | "USB Vendor Name" = "Motorola Solutions, Inc." | "Device Speed" = 2 | "idVendor" = 3245 | "kUSBProductString" = "TETRA PEI interface" | "kUSBAddress" = 6 | "kUSBVendorString" = "Motorola Solutions, Inc." | } | +-o AppleUSBHostCompositeDevice <class AppleUSBHostCompositeDevice, id 0x100002982, !registered, !matched, active, busy 0, retain 5> | { | "IOProbeScore" = 50000 | "CFBundleIdentifier" = "com.apple.driver.usb.AppleUSBHostCompositeDevice" | "IOProviderClass" = "IOUSBHostDevice" | "IOClass" = "AppleUSBHostCompositeDevice" | "IOPersonalityPublisher" = "com.apple.driver.usb.AppleUSBHostCompositeDevice" | "bDeviceSubClass" = 0 | "CFBundleIdentifierKernel" = "com.apple.driver.usb.AppleUSBHostCompositeDevice" | "IOMatchedAtBoot" = Yes | "IOMatchCategory" = "IODefaultMatchCategory" | "IOPrimaryDriverTerminateOptions" = Yes | "bDeviceClass" = 0 | } | +-o lghub_agent <class AppleUSBHostDeviceUserClient, id 0x100002983, !registered, !matched, active, busy 0, retain 7> | { | "IOUserClientCreator" = "pid 1438, lghub_agent" | "IOUserClientDefaultLocking" = Yes | } | +-o IOUSBHostInterface@0 <class IOUSBHostInterface, id 0x100002986, registered, matched, active, busy 0 (5 ms), retain 9> | | { | | "USBPortType" = 0 | | "IOCFPlugInTypes" = {"2d9786c6-9ef3-11d4-ad51-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"} | | "USB Vendor Name" = "Motorola Solutions, Inc." | | "bcdDevice" = 9238 | | "USBSpeed" = 3 | | "idProduct" = 36886 | | "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb")) | | "bInterfaceSubClass" = 0 | | "bConfigurationValue" = 1 | | "locationID" = 34734080 | | "USB Product Name" = "TETRA PEI interface" | | "bInterfaceProtocol" = 0 | | "iInterface" = 0 | | "bAlternateSetting" = 0 | | "idVendor" = 3245 | | "bInterfaceNumber" = 0 | | "bInterfaceClass" = 255 | | "bNumEndpoints" = 2 | | } | | | +-o lghub_agent <class AppleUSBHostInterfaceUserClient, id 0x100002988, !registered, !matched, active, busy 0, retain 6> | { | "UsbUserClientBufferStatistics" = {"IOMemoryDescriptor"=0,"IOBufferMemoryDescriptor"=0,"IOSubMemoryDescriptor"=0} | "IOUserClientCreator" = "pid 1438, lghub_agent" | "UsbUserClientBufferAllocations" = {"Bytes"=0,"Descriptors"=0} | "IOUserClientDefaultLocking" = Yes | } | +-o IOUSBHostInterface@1 <class IOUSBHostInterface, id 0x100002987, registered, matched, active, busy 0 (5 ms), retain 9> | { | "USBPortType" = 0 | "IOCFPlugInTypes" = {"2d9786c6-9ef3-11d4-ad51-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"} | "USB Vendor Name" = "Motorola Solutions, Inc." | "bcdDevice" = 9238 | "USBSpeed" = 3 | "idProduct" = 36886 | "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb")) | "bInterfaceSubClass" = 0 | "bConfigurationValue" = 1 | "locationID" = 34734080 | "USB Product Name" = "TETRA PEI interface" | "bInterfaceProtocol" = 0 | "iInterface" = 0 | "bAlternateSetting" = 0 | "idVendor" = 3245 | "bInterfaceNumber" = 1 | "bInterfaceClass" = 255 | "bNumEndpoints" = 2 | } | +-o lghub_agent <class AppleUSBHostInterfaceUserClient, id 0x10000298a, !registered, !matched, active, busy 0, retain 6> { "UsbUserClientBufferStatistics" = {"IOMemoryDescriptor"=0,"IOBufferMemoryDescriptor"=0,"IOSubMemoryDescriptor"=0} "IOUserClientCreator" = "pid 1438, lghub_agent" "UsbUserClientBufferAllocations" = {"Bytes"=0,"Descriptors"=0} "IOUserClientDefaultLocking" = Yes } more details in my comment.

Exception Type: SIGSEGV SEGV_ACCERR Exception Codes: fault addr: 0x0000000000000100 Crashed Thread: 4 2. Behavior & Context The crash occurs during normal HTTPS networking using standard URLSession (no direct usage of Network.framework nor boringssl APIs). It appears to be triggered during QUIC connection establishment or TLS fallback. The stack trace contains no application code frames — all symbols are from system libraries. The crash strongly indicates double-free, over-release, or dangling pointer inside nw_protocol_boringssl_options deallocation. 3. Questions for Apple Is this a known issue in iOS 26 within Network.framework / boringssl related to nw_protocol_boringssl_deallocate_options? What is the root cause of the over‑release / invalid objc_release in this path? Is there a workaround we can implement from the app side (e.g., disabling QUIC, adjusting TLS settings, or queue configuration)? Do you have a target iOS version or patch where this issue will be fixed? We can provide full crash logs and additional metrics upon request. 4. Additional Information Developed using Swift 5, with a deployment target of iOS 12+. Thank you for your support.

Dear Apple Developer Technical Support, I am currently developing a macOS network filtering solution using NetworkExtension with NEFilterDataProvider. During implementation of the handleOutboundData logic, we are using the following verdict: NEFilterNewFlowVerdict.filterDataVerdict( withFilterInbound: true, peekInboundBytes: InboundPeekBytes, filterOutbound: true, peekOutboundBytes: OutboundPeekBytes ) However, we have encountered an issue when SMB traffic is involved. When SMB protocol communication occurs, the network connection occasionally becomes unresponsive or appears to stall when peekOutboundBytes is set to a large value. Through testing, we observed the following behavior: On some systems, reducing the peekOutboundBytes value allows SMB communication to proceed normally. On other systems, even relatively small values can still cause the SMB connection to stall. This behavior appears inconsistent across different macOS environments. Because of this, we would like to clarify the following: Is there a documented or recommended maximum value for peekOutboundBytes when using NEFilterNewFlowVerdict.filterDataVerdict? Are there any internal limits or constraints within NetworkExtension that could cause SMB traffic to stall when the peek buffer size is too large? Are there best practices for selecting appropriate peekInboundBytes / peekOutboundBytes values when filtering high-throughput protocols such as SMB? If necessary, we can provide additional information such as macOS version, test environment details, and logs. Thank you for your assistance. Best regards, sangho

We began storing our users' appTransactionID as a quick lookup identifier for purchase history as it is back-dated and consistent between installs and can be signed by Apple. We've read through both the Storekit documentation and the app transfer documentation, but wanted to verify that a users appTransactionID remains consistent after an app has been transferred from one Apple developer account to another (assuming they have the proper shared secret info)? Basically, would the new developer team be seeing the same appTransactionID our current team sees for an existing user post-transfer?

We use AppShortcutsProvider with a parameterized App Shortcut. One of the entities has a dynamic display title (e.g. "Everyone is searching: {keyword}") that comes from UserDefaults and is returned in EntityQuery.suggestedEntities() and entities(for:). When we change the keyword and call updateAppShortcutParameters(), the Shortcuts app updates and shows the new title. In Spotlight (Siri Suggestions), the displayed title stays on the old value (e.g. still shows "Everyone is searching: 456" after we switched to "123"). On tap, the shortcut runs with the new value (123), so the execution is correct; only the displayed title in Spotlight is stale. Question: Is this expected? Is there any API or recommended approach to invalidate or refresh the Spotlight suggestion so the displayed title matches the current parameter, or should we avoid dynamic titles for the first suggestion for better UX?

I have several macOS applications that use CloudKit. I need to test and finds out what happens when the user signs out of their iCloud account. That's because the application may lose data after signing out and then signing in again. Every time I do that, it'll take 15, 20 minutes... I don't time it, but it takes quite a gigantic time to sign out as the spinner keeps rolling. Why does it take so long to just sign out? This sign out effect is untestable because it takes a long time to sign out of an iCloud account and then make changes to the code and then test again. In case you need to know, my system version is Sequoia 15.7.

aka MKLocalSearch.Request in Swift. Today my users reported that our address auto-complete functionality was returning strange results. We narrowed the issue down to pointOfInterestFilter being set. Sample code below: MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init]; request.region = self.region; request.naturalLanguageQuery = addressString; request.resultTypes = MKLocalSearchResultTypeAddress; request.pointOfInterestFilter = [MKPointOfInterestFilter filterIncludingAllCategories]; That last line is the problem. When I stopped setting request.pointOfInterestFilter the MKLocalSearch started working as it always had. To further hammer home the point, with request.pointOfInterestFilter unset I set resultTypes to MKLocalSearchCompleterResultTypePointOfInterest (aka .pointOfInterest) and the issue returned. It seems Apple made a change on their backend recently such that pointOfInterestFilter now overrides resultTypes.

I'm building a macOS network monitor using NEFilterDataProvider as a system extension, distributed with Developer ID signing. On macOS 26.3 (Tahoe), sysextd consistently rejects the activation request with "no policy, cannot allow apps outside /Applications" — despite the app being in /Applications and passing every verification check. I'm aware of the known Xcode NE signing bug (r. 108838909) and have followed the manual signing process from Exporting a Developer ID Network Extension. I've also tried both xcodebuild build and xcodebuild archive workflows — identical failure.

System-level checks: Rebooting — no change Killing sysextd — no change Removing com.apple.quarantine xattr — no change chown root:wheel on app bundle — no change lsregister -r (reset Launch Services) — no change Waiting 27 days for certificate propagation — no change Reinstalling via Finder drag-to-Applications — no change No MDM or configuration profiles installed /Library/SystemExtensions/db.plist shows extensionPolicies: [] (empty) Key observation Pre-existing network extensions activated before macOS 26 work fine on this machine. For example, Tailscale's NEPacketTunnelProvider shows state: activated_enabled in the system extensions database — it was activated on a prior macOS version and is still running. Only new system extension activations fail. I've seen similar Tahoe-specific reports from LuLu (same NEFilterDataProvider type, Developer ID distribution): LuLu #825 LuLu #831 Questions Is this a known regression in macOS 26's sysextd policy evaluation for new Developer ID system extension activations? sysextd's policy check fails after all signature and trust evaluation succeeds. Is there a separate trust/policy path that sysextd consults beyond what spctl, codesign, and CodeSigningHelper verify? Is there anything else I should be checking? I have a sysdiagnose captured immediately after the failure, a minimal reproducer project, and full raw sysextd logs available on request.

Hello, I'm trying to figure out why an Int is being inferred over my explicit Double I'm parsing a CSV that contains 2 tables. I don't own the data so I'm not able to change it. The first row contains one cell that's used as a title for the document The second row is empty The third row contains one cell that's used as the header for the first table There is a header row for the table There's a dynamic number of rows for this table The an empty spacer row There is a row that's used as a title for the second table There is a header row for the table There's a dynamic number of rows for this table Im able to separate and create two DataFrame's from the data without issue. And this is the initializer I'm using. DataFrame( csvData: csvData, rows: rows, types: types, options: options ) Column names and their CSV types looks like this var types: [String: CSVType] { [ // ... "Column 38": .double, // ... ] } The data in the CSV is 0 nil nil nil 2 And this is what the one of the columns in question looks like when printed ▿ 38 : ┏━━━━━━━━━━━┓ ┃ Column 38 ┃ ┃ <Int> ┃ ┡━━━━━━━━━━━┩ │ 0 │ │ nil │ │ nil │ │ nil │ │ 2 │ └───────────┘ - name : "Column 38" - count : 5 ▿ contents : PackedOptionalsArray<Int> ▿ storage : <PackedOptionalsStorage<Int>: 0x600000206360> The docs state /// - types: A dictionary of column names and their CSV types. /// The data frame infers the types for column names that aren't in the dictionary. Since types contains the column name and it's still being inferred, my assumption is that the issue involves the renaming of the header row when it has empty cells occurs after the types are checked. Edit: After setting hasHeaderRow: false from true and adjusting my row offset, the types are now being assigned correctly. I'd recommend opening a feedback enhancement where renaming columns occurs before type assignment.

Some users have switched to wearing smart rings instead of an Apple Watch, but they still want their rings to close throughout the day in Apple Fitness to keep their streaks going. I've noticed that the 3rd party smart ring apps do not affect the progress of the exercise and move rings unless the user puts on their Apple Watch and syncs with there iPhone throughout the day. Is there a way to make the progress rings update throughout the day without having to connect an Apple Watch periodically?

I’m encountering a strange, sporadic error in FileManager.replaceItemAt(_:withItemAt:) when trying to update files that happen to be stored in cloud containers such as iCloud Drive or Dropbox. Here’s my setup: I have an NSDocument-based app which uses a zip file format (although the error can be reproduced using any kind of file). In my NSDocument.writeToURL: implementation, I do the following: Create a temp folder using FileManager.url(for: .itemReplacementDirectory, in: .userDomainMask, appropriateFor: fileURL, create: true). Copy the original zip file into the temp directory. Update the zip file in the temp directory. Move the updated zip file into place by moving it from the temp directory to the original location using FileManager.replaceItemAt(_:withItemAt:). This all works perfectly - most of the time. However, very occasionally I receive a save error caused by replaceItemAt(_withItemAt:) failing. Saving can work fine for hundreds of times, but then, once in a while, I’ll receive an “operation not permitted” error in replaceItemAt. I have narrowed the issue down and found that it only occurs when the original file is in a cloud container - when FileManager.isUbiquitousItem(at:) returns true for the original fileURL I am trying to replace. (e.g. Because the user has placed the file in iCloud Drive.) Although strangely, the permissions issue seems to be with the temp file rather than with the original (if I try copying or deleting the temp file after this error occurs, I’m not allowed; I am allowed to delete the original though - not that I’d want to of course). Here’s an example of the error thrown by replaceItemAt: Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “test-file.txt” in the folder “Dropbox”." UserInfo={NSFileBackupItemLeftBehindLocationKey=file:///var/folders/mt/0snrr8fx7270rm0b14ll5k500000gn/T/TemporaryItems/NSIRD_TempFolderBug_y3UvzP/test-file.txt, NSFileOriginalItemLocationKey=file:///var/folders/mt/0snrr8fx7270rm0b14ll5k500000gn/T/TemporaryItems/NSIRD_TempFolderBug_y3UvzP/test-file.txt, NSURL=file:///Users/username/Library/CloudStorage/Dropbox/test-file.txt, NSFileNewItemLocationKey=file:///Users/username/Library/CloudStorage/Dropbox/test-file.txt, NSUnderlyingError=0xb1e22ff90 {Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “test-file.txt” in the folder “NSIRD_TempFolderBug_y3UvzP”."

"Dummy text".write(to: tempURL, atomically: false, encoding: .utf8)) != nil else { return } do { // Use replaceItemAt to safely move the new file into place. _ = try fileManager.replaceItemAt(savingURL, withItemAt: tempURL) print("save succeeded!") try? fileManager.removeItem(at: replacementDirURL) // Clean up. } catch { print("save failed with error: \(error)") // Note: if we try to remove replaceDirURL here or do anything with tempURL we will be refused permission. NSAlert(error: error).runModal() } } If you run this code and set savingURL to a location in a non-cloud container such as your ~/Documents directory, it will run forever, resaving the file over and over again without any problems. But if you run the code and set savingURL to a location in a cloud container, such as in an iCloud Drive folder, it will work fine for a while, but after a few minutes - after maybe 100 saves, maybe 500 - it will throw a permissions error in replaceItemAt. (Note that my real app has all the save code wrapped in file coordination via NSDocument methods, so I don’t believe file coordination to be the problem.) What am I doing wrong here? How do I avoid this error? Thanks in advance for any suggestions.

Greetings fellow devs, After accepting the Alternative Terms Addendum for Apps in the EU and adding the Storekit External Purchases or Offers capability via App Store Connect in our app identifier, the entitlement showing up in xcode is com.apple.developer.storekit.custom-purchase-link.allowed-regions and has the value 'jp'. How can we change the value for that entitlement to 'gr'? We tried changing it in xcode, but we get the error <Provisioning profile "iOS Team Provisioning Profile: [app identifier]" doesn't match the entitlements file's value for the com.apple.developer.storekit.custom-purchase-link.allowed-regions entitlement.>. In Certificates, Identifiers and Profiles in the developer account there is no way to configure that capability. We sent a request to support and they only gave a link to documentation and to the forum here. We have a completed every business agreement requested and we have chosen Greece as the organisation region and the app's availability region wherever possible. We haven't found anywhere that Japan would be chosen to explain the entitlement given. So where can this entitlement about allowed regions be configured? Xcode version is 16.4 and iOS minimum deployments is 18
