TN3138: Handling App Store receipt signing certificate change
Hi (from France) I have a MacOS application which handles the App Store receipt by requesting at the url "https://buy.itunes.apple.com/verifyReceipt". From the response, I can know what are the inApps bought by the user and that suits for me. I don't know if if I must change something in my code accordingly to this TN3118. Does someone knows the response ? Best regards.

'NDEF is disallowed' Xcode 16.2
Invalid entitlement for core nfc framework. The sdk version '18.2' and min OS version '14.0' are not compatible for the entitlement 'com.apple.developer.nfc.readersession.formats' because 'NDEF is disallowed'. Anyone knows what is the correct configuration SDK version and minimum iOS deployment target for NFC that has NDEF format?

"InvalidProviderToken" with APN push service when using code-generated token
Problem We have successfully set up push notifications using Apple APN service, that is push notifications work when using a token generated using the JSON Web Token Generator in the Push Notification console. However, we get an "InvalidProviderToken" error when creating using our own token using the following code. The Key and TeamID is definitely correct (obviously, censored in the below code). When pasting our token in the JSON Web Token Validator in the Push Notification console we get the error „Invalid signing key“. We merely pasted our secret key in our setNewTokenIfNeeded code, separated on four lines using the “““ style. Does anyone know why this error happens? Given that it works when we upload our .p8 file to the JSON Web Token Generator and we simply paste the text of this file (excluding the lines with "-----BEGIN/END PRIVATE KEY-----") I guess our secret key is correct? Code to generate token fileprivate var currentToken: String? fileprivate var currentTokenCreateTime: Date? fileprivate func setNewTokenIfNeeded() { // Ensure, token is at least 20 minutes but at most 60 minutes old if let currentTokenCreateTime = currentTokenCreateTime { let ageOfTokenInSeconds = abs(Int(currentTokenCreateTime.timeIntervalSinceNow)) NSLog("Age of token: \(Int(ageOfTokenInSeconds / 60)) minutes.") if ageOfTokenInSeconds <= 20 * 60 { return } } // Generate new token NSLog("Renewing token.") let secret = """ ABCABCABCABCABCABCABCABCABCABCABCABC+ABCABC+ABCABCABC+ABCABCAB/+ ABCABCABCABCABCABCABCABCABCABCABCABC+ABCABC+ABCABCABC+ABCABCAB/+ ABCABCABCABCABCABCABCABCABCABCABCABC+ABCABC+ABCABCABC+ABCABCAB/+ ABCABCAB """ let privateKey = SymmetricKey(data: Data(secret.utf8)) let headerJSONData = try!

JSONSerialization.data(withJSONObject: payload, options: .prettyPrinted). Could this be the culprit, given our secret key contains „/„ and „+“? Many thanks!

Launch URL
Hi I am developing a game app with Epic Unreal Engine. I am testing this as testFlight these days. My problem is “launch URL” what a function in Unreal Engine. This is a function that allows user to search the Internet with the entered URL. It worked well before. But not now. I don't know when it did start not working. It's like after the iPhone IOS update or the Xcode update. Mac sequoia 15.1.1 Xcode 16.2 ( Unreal Engine 5.4.4 ) IOS is 18.2. but It didn't work since the just previous version. Any advice can I get?

PushKit Voip notifications not triggering CallKit UI in the background
I am trying to add voip call functionality to my app. It works as expected while the app is in the foreground. But in the background it does not. I have registered the app as requiring background voip permissions. My implementation doesn't fit into one of these posts, so here is a gist: https://gist.github.com/BrentMifsud/4be43c022c1279f04ecb56250a86b3f1

App Store Review always got 4.3 for my apps
I created an app and submitted to app store for review and got a rejection with "4.3(a) - Design - Spam". This one was created for brand new, and I didn't find any similar apps in App store. I searched in this forum but am not sure if it is because I used flutter to build my app? How could I get a bit more specific detail why it got rejected? Guideline 4.3(a) - Design - Spam We noticed your app shares a similar binary, metadata, and/or concept as apps submitted to the App Store by other developers, with only minor differences. Submitting similar or repackaged apps is a form of spam that creates clutter and makes it difficult for users to discover new apps. Next Steps Since we do not accept spam apps on the App Store, we encourage you to review your app concept and submit a unique app with distinct content and functionality.

Can users create their own subscription plans?
I'm considering developing an app where users can create their own subscription plans by freely setting their prices, similar to YouTube's membership feature. I understand that in-app purchases must be used to unlock features within the app. With that in mind, I searched for APIs to enable this functionality but couldn't find relevant information. When I contacted Apple directly, they mentioned that they couldn't provide specific answers unless the app is under review. If anyone has knowledge about the following points, I would greatly appreciate your response: Is it possible to implement a feature similar to YouTube's membership using in-app purchase APIs? If it's not feasible with in-app purchases, is it allowed to use external payment services like Stripe?

Apple Intelligence on Workspace ONE
Hello! It's my first time posting in this forum. Apple Intelligence is enabled by default in Workspace ONE (WS1). I was wondering if Apple Intelligence can access or process corporate data within (WS1) corporate apps, which are containerized? Thank you!

StoreKit2 Subscription Verification
My question is simple, I do not have much experience in writing swift code, I am only doing it to create a small executable that I can call from my python application which completes Subcription Management. I was hoping someone with more experience could point out my flaws along with giving me tips on how to verify that the check is working for my applicaiton. Any inight is appreciated, thank you. import Foundation import StoreKit class SubscriptionValidator { static func getReceiptURL() -> URL? { guard let appStoreReceiptURL = Bundle.main.appStoreReceiptURL else { print("No receipt found.") return nil } return appStoreReceiptURL } static func validateReceipt() -> Bool { guard let receiptURL = getReceiptURL(), let receiptData = try? Data(contentsOf: receiptURL) else { print("Could not read receipt.") return false } let receiptString = receiptData.base64EncodedString() let validationResult = sendReceiptToApple(receiptString: receiptString) return validationResult } static func sendReceiptToApple(receiptString: String) -> Bool { let isSandbox = Bundle.main.appStoreReceiptURL?.lastPathComponent == "sandboxReceipt" let urlString = isSandbox ? "https://sandbox.itunes.apple.com/verifyReceipt" : "https://buy.itunes.apple.com/verifyReceipt" let url = URL(string: urlString)! let requestData: [String: Any] = [ "receipt-data": receiptString, "password": "0b7f88907b77443997838c72be52f5fc" ] guard let requestBody = try?

Message Filter Extension and multiple servers
In the documentation for a Message Filter Extension it states: If you have servers that can help your app extension determine how to handle a message, you must add the Associated Domains capability to your Xcode project and specify those domains. (https://developer.apple.com/documentation/sms_and_call_reporting/sms_and_mms_message_filtering/creating_a_message_filter_app_extension) The words servers and domains are in the plural. If it's possible to specify multiple servers/domains for a Message Filter Extension then how is that done? There's no documentation nor reference for that. If multiple domains can be added to the info.plist then what is the iOS behavior in that case? Can the extension supply/change which domain is used at run time?

Handling Empty in_app Data in iOS Order Verification and Verification Result in receipt.app_item_id
Body: Hello, We are currently implementing iOS order verification and have encountered an issue. Some of the receipts we verify return with an empty in_app array, which makes it impossible to determine whether there is a valid in-app purchase. Below is the code we’re using for verification and the result we receive: Code Example: public function iosVerifyReceipt($receipt, $password = '', $sandbox = false) { $url = $sandbox ? 'https://sandbox.itunes.apple.com/verifyReceipt' : 'https://buy.itunes.apple.com/verifyReceipt'; if (empty($password)) { $data = json_encode(['receipt-data' => $receipt]); } else { $data = json_encode(['receipt-data' => $receipt, 'password' => $password]); } $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $result = curl_exec($ch); curl_close($ch); $result = json_decode($result, true); $result = $result ?? []; $result['sandbox'] = $sandbox; if ($result['status'] != 0) { Log::warning('ios verify receipt failed', ['receipt' => $receipt, 'result' => $result, 'sandbox' => $sandbox]); if ($result['status'] == 21007) { return $this->iosVerifyReceipt($receipt, $password, true); } } return $result; } // Order validation check if (empty($result) || $result['status'] != 0) { throw new BadRequestHttpException("Ios Order Verify Error"); } $appItemId = $result['receipt']['app_item_id'] ?? ""; if ($appItemId != MY_APP_ID) { throw new BadRequestHttpException("Ios Order Verify Error"); } $inApp = array_filter($result['receipt']['in_app'] ?? [], function ($item) use ($transactionId, $order) { return $item['transaction_id'] == $transactionId && $item['product_id'] == $order->getProductId(); }); if (empty($inApp)) { throw new BadRequestHttpException("Ios Order Verify Error"); } Array ( [receipt] => Array ( [receipt_type] => Production [adam_id] => * [app_item_id] => * [bundle_id] => * [application_version] => * [download_id] => * [version_external_identifier] => * [receipt_creation_date] => 2025-02-11 04:06:47 Etc/GMT [receipt_creation_date_ms] => * [receipt_creation_date_pst] => 2025-02-10 20:06:47 America/Los_Angeles [request_date] => 2025-02-11 15:54:56 Etc/GMT [request_date_ms] => * [request_date_pst] => 2025-02-11 07:54:56 America/Los_Angeles [original_purchase_date] => 2025-02-11 04:02:41 Etc/GMT [original_purchase_date_ms] => * [original_purchase_date_pst] => 2025-02-10 20:02:41 America/Los_Angeles [original_application_version] => 5511 [preorder_date] => 2025-01-17 21:12:28 Etc/GMT [preorder_date_ms] => * [preorder_date_pst] => 2025-01-17 13:12:28 America/Los_Angeles [in_app] => Array ( ) ) [environment] => Production [status] => 0 [sandbox] => ) Problem Description: • We are noticing that in some orders, the in_app array is returned as empty. This causes difficulty in verifying the presence of in-app purchases. • Our validation logic assumes that if in_app is empty, the order is invalid, but we would like clarification on whether this is correct or if such a scenario is normal under certain conditions. Actions Taken: • We have reviewed Apple’s documentation and other related resources, but no clear explanation is given about when in_app might be empty. • Can we safely rely on an empty in_app array to consider the order invalid, or should we investigate further for potential issues like delays or errors during the verification process? We would appreciate your guidance on how to handle such cases. Thank you for your support!

Any way to adjust the speechRecognitionMetadata pause duration?
Speech Framework I've been checking for SFSpeechRecognitionMetadata to determine the end of a sentence when using Voice Recognition. Yet it doesn't detect small pauses but only large ones, so that I've transcribed basically an entire paragraph before going onto the next one. Besides implementing your own timer, are there any other ways to have more natural pauses to detect the end of sentences, similar to the browser's Web Speech recognition? Since it's in Safari, I assume there should be some similar feature that can be equivalent in MacOS.

error 49244 when using asr
a few times, for reasons unknown to me, asr restore processes broke with error 49244. Basically, the process get interrupted, most cases when is about to finish, with just a laconic message saying "Volume replication failed - error 49244". Where can I get information on this error, what exactly means, what causes it and more important, how to troubleshoot it. Any help will be appreciated, Thanks!!

IPad connected to DSLR captures incomplete image
At present, I am using the avfoundation external device API to connect my iPad to a DSLR camera for data collection. On my end, I am using AVCapture Video Data Output to obtain raw data for processing and rendering. However, the pixelbuf returned from the system layer is incomplete, with only a portion cropped in the middle. But using the Mac API is normal. I would like to ask how to obtain the complete pixelbuf of the image on iPad

Handling Data Download Backpressure in URLSession
I am developing an application that processes a video file stored on a server. I use URLSessionDataTask with a delegate handler to download the file. It is not necessary to download the entire file at once. Instead, I can load small chunks of the file as needed. This approach helps minimize memory consumption. I am trying to design a network layer that supports this behavior. Ideally, I would like to have an interface similar to: func readMoreData(length: Int) async throws -> Data Problems I Encountered: It seems that URLSessionDataTask does not allow controlling how many bytes will be downloaded. It always downloads the entire request. If I call suspend on URLSessionDataTask, the network activity does not stop, and the file keeps downloading. If I upgrade the dataTask to a StreamTask, the file still downloads, though reading bytes can be done through the StreamTask API. I would prefer behavior similar to AsyncHTTPClient (a Swift Server library) or Network Framework. These frameworks allow controlling the number of bytes downloaded at a time. Unfortunately, they do not fit the specific requirements of my project. Am I correct in understanding that controlling the download process is not possible with URLSessionDataTask? As a possible solution, I am considering using HTTP Range Requests, though this would increase the number of additional server requests, which I would like to avoid.

ManagedSettingStore limits and groups
So what's the point of being able to block unto 50 apps per ManagedSettingStore via store.application.blockedApplications (which works fine) until removing the blocked apps or clearing the store. Where the following occurs if you have a social networking group with more than 9 apps only 9 apps will go back into the group and all the others will go onto the springboard all jumbled if you end up with an empty group then tap into the group, it is removed then during the reset all apps are placed back on to the springboard

Apple Pay testing in Sandbox for Austria
Dear Team, we are from Austria and want to test our apple pay on the web implementation via Apple Sandbox. As far as we can see Austria is not on the list that sandbox supports Apple Pay testing for. Can you please advise how can we move forward with testing? We have already created and also tried out our Sandbox account on iPhone 11 and successfully added test cards to the Wallet. Can we expect please in later stage some restrictions due to our region? Thank you in advance. Iveta
