Hello all Synopsis: document based SwiftData app breaks document handling after first save due to internal error saving the -shm file. Long: i am working on a small document based SwiftData app for macOS. The UI works well as long as the document was not saved. After saving the document and reopening it, I get an error consistently in console: BUG IN CLIENT OF libsqlite3.dylib: database integrity compromised by API violation: vnode unlinked while in use: /Users/vrunkel/Library/Containers/de.ecoobs.CurtailmentAnalyzer/Data/tmp/TemporaryItems/NSIRD_CurtailmentAnalyzer_mrXKMs/NewDocument/StoreContent-shm So somehow the -shm file is still referenced to NewDocument created when the app opens an untitled document and resides in the temporary folder. I have saved the document to my documents folder. After reopening and the above error deletion or addition of items crashes the app with a long backtrace to view updating: Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread. I am not creating any threads or do background work. If I do not save the document but work within the new untitled document no problems occur. Even closing the app and reopening the untitled new doc (happens automatically) all is fine. To rule out any influence of my existing view structure I have created the most simple test case - Xcode -> New Project -> macOS document based app configured to use SwiftData. Same behaviour. After saving a new document the addition/deletion of items causes the thread-induced crash and shows the error in console when opening the document. I am using latest versions of Xcode 15.0 and macOS 14.0 Any ideas? thx, volker

Hello. Our application performs encoding and decoding of large json files which sometimes may take up to 1,5GB of RAM memory. We understand that this may be a problem for devices with low RAM memory (3GB). But before iOS 26.4 we didn't have much occurrences (3 for the last 90 days). Starting from iOS 26.4 it started to crash a lot. Can the reason be that iOS 26.4 occupies more RAM memory so there is less memory left for our app? Or maybe starting from iOS 26.4 there is less RAM memory allocated per app? The crash message is Fatal error: failed to allocate 392 bytes of memory with alignment 8

DJI's DNG files display abnormally in the Apple Photos app on iOS devices, with dark areas showing as very black, but the same files appear normal in Photoshop. I'm curious about what causes this issue.

Hello Apple Developer Support / StoreKit Team, We recently observed a behavior regarding the appAccountToken in App Store Server Notifications v2 that seems to completely contradict the official documentation. According to the Set App Account Token documentation: The same appAccountToken continues to apply to renewal transactions if the customer upgrades, downgrades, or cross-grades the subscription. However, we encountered a scenario where an active in-app crossgrade resulted in an updated/overwritten appAccountToken inside the subsequent JWSRenewalInfoDecodedPayload, despite our backend never calling the Set App Account Token REST API. Our Observation: A user subscribes to our 1-month plan (Product A). Apple generates an originalTransactionId bound to their initial appAccountToken (Token A). Later, a crossgrade to a 1-year plan (Product B) is initiated from within the app while the user is logged into a different account in our system (Token B), but using the same underlying Apple ID on the device. When the crossgrade takes effect at the next renewal date, we receive a DID_RENEW webhook. The Anomaly (See Attached Screenshots): Upon decoding the JWSRenewalInfoDecodedPayload from the webhook, we noticed that the appAccountToken had unexpectedly changed to the new token (Token B). As shown in the attached redacted screenshots: Screenshot 1 (Before/Original): JWSRenewalInfoDecodedPayload for Product 00001 shows the appAccountToken ending in ...e9a. Screenshot 2 (After Crossgrade): JWSRenewalInfoDecodedPayload for Product yearly_saver shows the appAccountToken has mutated to ending in ...507, even though the originalTransactionId remains exactly the same. To reiterate, our server did not call the POST /inApps/v1/subscriptions/appAccountToken/{originalTransactionId} endpoint to manually overwrite this token at any point. Our Questions: Is this the intended StoreKit 2 behavior? Does Apple automatically overwrite the base appAccountToken in the RenewalInfo if a new token is somehow associated during an active in-app crossgrade transaction? If this is intended, could the documentation be clarified? The current phrasing strongly suggests the token is permanently locked to the initial purchase and will never change during crossgrades unless the REST API is explicitly called. While this behavior is actually quite helpful for our backend to track multi-account users, we want to ensure we aren't relying on an undocumented bug that might be patched unexpectedly. Any insights from the StoreKit engineering team would be highly appreciated. Thank you!

Hello, I am trying to gather information on the global availability of the Apple Find My Network. Specifically, I would like to know: Which countries currently support this feature? Is it available worldwide, with only a few specific countries/regions facing usage restrictions or complete unavailability? I have already reviewed the public Feature Availability page, but was unable to find any documentation addressing regional restrictions. Any clarification or pointers to relevant documentation would be greatly appreciated. Thank you!

While attempting to read a user’s daily step history spanning backward to the last 7 days, a small but consistent subset of users encounter Error Code 3 with the underlying error description: Error Code 3 "Unable to invalidate interval: no data source available." When this error occurs, we are entirely unable to read their step history. We have received ~10 direct user reports of this within the last couple of weeks.

I’m using Network Framework with UDP and calling: connection.receive(minimumIncompleteLength: 1, maximumLength: 1500) { data, context, isComplete, error in ... // Some Logic } Is it possible for this completion handler to be called with data==nil if I haven't received any kind of error, i.e., error==nil and the connection is still in the .ready state?

This discussion is for iOS/iPadOS. I've written an NEAppProxyProvider network extension. I'd like to test it. I thought that using the "NETestAppMapping" dictionary was a way to get there, but when I try to instantiate an NEAppProxyProviderManager to try to install stuff, the console tells me "must be MDM managed" and I get nowhere. So can someone tell me, can I at least test the idea without needing to first get MDM going? I'd like to know if how I'm approaching the core problem even makes sense. My custom application needs to stream video, via the SRT protocol, to some place like youtube or castr. The problem is that in the environment we are in (big convention centers), our devices are on a LAN, but the connection from the LAN out to the rest of the world just sucks. Surprisingly, cellular has better performance. So I am trying to do the perverse thing of forcing traffix that is NOT local to go out over cellular. And traffic that is completely local (i.e. talking to a purely local server/other devices on the LAN) happens over ethernet. [To simplify things, wifi is not connected.] Is an app proxy the right tool for this? Is there any other tool? Unfortunately, I cannot rewrite the code to force everything through Apple's Network framework, which is the one place I know we can say "use cellular." [E.g. URLSession() has absolutely no way of forcing cellular, and even so, the low level streaming library I use is written with raw sockets, and its not feasible for me to rewrite it.] Any other suggestions of how to accomplish this "send non-local traffic to cellular, all local traffic out over ethernet" gratefully welcomed!

Hello, I am developing a macOS Launch Daemon (packaged as a bundle) that acts as an XPC server. For debugging purposes, I am trying to run the daemon's executable directly from the terminal via sudo ./mydaemon.app/Contents/MacOS/myexecutable. Initially, I added the com.apple.security.application-groups entitlement to the daemon. However, when starting the process, it failed to create the XPC service with the following errors: Unsatisfied entitlements: com.apple.security.application-groups Soft-restriction provisioning profile validation failure: Error Domain=AppleMobileFileIntegrityError Code=-413 "No matching profile found" UserInfo={NSURL=, unsatisfiedEntitlements=, NSLocalizedDescription=No matching profile found} listener failed to activate: xpc_error=[1: Operation not permitted] To resolve the profile validation failure, I registered a new App Group in the Apple Developer Portal, generated a new provisioning profile for the daemon that includes this group, and embedded it into the bundle (Contents/embedded.provisionprofile). Now, the previous profile error is gone, but I am getting a new identity conflict error, and the XPC listener still fails: Two equal instances have unequal identities. <anon<myproc_name>(501) pid=2818 AUID=501> and <anon<myproc_name>(501)(262) pid=2818 AUID=262> listener failed to activate: xpc_error=[1: Operation not permitted] My questions are: What exactly causes the Two equal instances have unequal identities error? I noticed the Audit UID difference (AUID=501 vs AUID=262). Why does NSXPCListener still fail with Operation not permitted? What is the recommended workflow for debugging a Launch Daemon that requires an App Group provisioning profile for XPC communication? Thank you in advance!

While going through the documentation for NWConnection, there seems to be state known as .waiting which means that the connection is waiting for a path change. For TCP, the state is understandable and can occur under some scenarios. But for the case of UDP, I have following queries: Why do we need .waiting state for the case of UDP? Even if we do need .waiting state for UDP, when all does this state occurs?

iOS 26.4系统上，我们发现三个问题： 1.调用了finishTransaction接口，但是在App重新启动后，[SKPaymentQueue defaultQueue].transactions仍然会有这笔订单。 2.支付完成后，[[NSBundle mainBundle] appStoreReceiptURL]]，拿到的票据解析出来里面的商品是空的，需要延迟2秒钟左右在调用[[NSBundle mainBundle] appStoreReceiptURL]]才能获取有效票据。 3.支付完成后，如果用户没有点击最后弹出的确认弹框，等待5秒钟，系统会自己回调 - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions; 代理方法。正常应该是用户点击了最后弹出的确认弹框，在回调- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions;方法。 我们在苹果开发者论坛上面找到其他开发者反馈的类似问题，链接如下： https://developer.apple.com/forums/thread/817700 https://developer.apple.com/forums/thread/792437?answerId=849557022#849557022 https://developer.apple.com/forums/thread/817834 https://developer.apple.com/forums/thread/817706 https://developer.apple.com/forums/thread/818586 我们有大量用户升级到了26.4系统，这对于我们造成了巨大的困扰，我们需要你们的帮助，感谢！

I've submitted a couple of pieces of feedback regarding broken WPA3 support on iOS 26 for the iPhone 17 Pro Max, and I've seen various access point vendors report that the GCMP256 cypher is not working. If you use WPA2, there is no issue. The problem I'm running into comes down to WPA3 being mandatory on 6 GHz. Some vendors have reported that disabling GCMP256 on Cisco Meraki hardware solves the problem. No other major vendor exposes this level of options. Does anyone know if it's possible to get more verbose diagnostic information out of the WiFi stack? I need actual information about why the negotiation fails, the technician-level stuff.

Summary I'm using Background Assets to download Apple-hosted Asset Packs(downloadPolicy = onDemand). The first download cancellation succeeds, but on the second and subsequent downloads, progress.cancel() fails to work and the download completes to the end. Environment iOS 26.0 – 26.3 RC (all produce the same result) Xcode Version 26.2 (17C52) Using Apple-hosted Asset Packs Steps to Reproduce Start downloading an Asset Pack Call progress.cancel() during download → Succeeds Start downloading the same Asset Pack again Call progress.cancel() during download → Fails (download completes to the end) Observed Error Logs After 1st cancellation: A download with the ID "X-XXXXXXXX-XXX" failed: Error Domain=NSURLErrorDomain Code=-999 "cancelled" ↑ This is expected (cancellation succeeded) The fact that version 0 of the asset pack with the ID "X-XXXXXX-XXX" finished being downloaded couldn't be reported: Error Domain=NSCocoaErrorDomain Code=3851 "Property list invalid for format: 200 (property lists cannot contain objects of type 'CFError')" ↑ Problem: Unable to serialize CFError to plist 2nd cancellation attempt: The download with the ID "X-XXXXXX-XXX" couldn't be canceled: Error Domain=BAErrorDomain Code=113 "The requested download operation failed because the download object did not exist." ↑ The download object we're trying to cancel supposedly doesn't exist Implementation Code // Cancel implementation func cancel(tag: String) async { let statusUpdates = AssetPackManager.shared.statusUpdates(forAssetPackWithID: tag) for await statusUpdate in statusUpdates { if case .downloading(_, let progress) = statusUpdate, progress.isCancellable { progress.cancel() } } } Analysis It appears that when the first cancellation occurs, the system internally tries to save the cancellation state to a plist, but fails to serialize the CFError object. This seems to cause an inconsistent internal state, preventing the system from correctly recognizing the download object on subsequent downloads. Questions Is there a workaround? Is there a planned fix for a future iOS version?

I have two Macbook Pros: 14" M4 Pro (company) 16" M4 Max (personal) I work remote full-time and recently purchased 2 of the new Studio Display XDRs. Everything works perfectly however I chose to connect them to the M4 Max. I have a caldigit Element TB5 hub and can daisy chain both monitors through that perfectly. With that said, no matter how I plug them into the M4 Pro I can only ever get one to light up at a time. What I have tried to resolve it: Plug them in individually to the m4 pro Plug them in one at a time, force them to 60hz and then plug them both in. Daisy Chaining the displays Daisy Chaining the displays through the TB5 Hub Nothing works. Only one display comes on and its whichever is plugged in first. I have even tried lowering the refresh to as low as it goes on both manually then plugging them back in. Still nothing. From what I am reading it appears to be that the M4 Pro has 3 display lanes and when I plug the first studio display XDR it is using 2 lanes. If I go down to 60hz which is what the original studio display was, then it should theoretically go down to 1 display lane allowing a second to be plugged in. A bunch of people had the older studio display running 2x 5k ASD monitors on the M4 Pro. Now with the latest Studio Display XDR I am stuck. I was researching possibly editing the EDID of each to mimic the older studio display, but I don't know how to do that easily without BetterDisplay and right now I have no ability to install that. There is a chance I can get approval to run commands / BetterDisplay to get this working if a solution can be found. What I think the ultimate fix is for the firmware / macOS to realize the limitation, force the studio display XDR to 60hz when a second monitor is plugged in and they both would work. A single Studio Display XDR could run 120hz, but immediately upon plugging a second one it swaps to 60hz. I am completely fine with that scenario. I have found a few discussions about this topic with the main one being on apple discussions: https://discussions.apple.com/thread/256262701?sortBy=rank&answerId=261888577022 Someone sort of gave me this idea on Mac because they were trying to use the studio display XDR on windows and it appears to have worked with cloning an older ASD EDID on the new model: https://www.reddit.com/r/mac/comments/1s3ani5/got_studio_display_xdr_working_on_windows_pc_5k/ I don't really know what else to do. I opened a ticket with support. Case # 102853480566, but it went no where. I got disconnected during the first call after describing everything and when they reached back out they didn't even give me 2 seconds to pick up and they hung up and closed the ticket. I really don't want to return the displays because they are beautiful and work beautifully on the m4 max. They should work with 60hz on the m4 pro. Who / How / When can we get this resolved? I would be happy to work with an Apple dev / engineer to help resolve this.

I created two sample apps — one sandboxed and one non‑sandboxed. I tested reading Managed Preferences using bash commands, CFPreferencesCopyValue for a domain, and defaults read. Everything works correctly only when the sandbox is disabled in the entitlements. When the sandbox is enabled, I’m unable to read values from /Library/Managed Preferences/. Is there any supported way for a sandboxed macOS app to read an MDM-delivered preference plist under /Library/Managed Preferences/? Any guidance on the correct and Apple‑supported method would be appreciated.

Since updating the OS to 26.4, the app has been crashing more often after I launch it. The devices on which this issue has been confirmed are as follows: ・iPhone SE (2nd generation) ・9th-generation iPad ・8th-generation iPad ・5th-generation iPad mini We have confirmed that the application functions properly on all devices prior to the OS update.

Prerequisites We plan to sell non-consumable items via in-app purchases. The app includes a restore button. We understand that after a payment is completed on a smartphone, the server must verify the receipt and activate the item in the database, and the app must then execute the transaction finish process. Due to our app’s constraints, there are specific cases where we must execute the transaction finish process on the app side without first performing the item activation process in the database. We do not know exactly what the transaction finish process entails. Questions What are the implications in the following cases? The payment was completed, but the product activation process in our database failed, and the transaction finish process was not executed on the app side. After restarting the app, an OS notification indicating an incomplete transaction appeared, and only the finish process was executed. In this scenario, we assume that the OS notification will not appear next time, and the user can simply activate the purchase by starting a transaction recovery. Are there any potential concerns or bugs that might occur? What are the implications if the product activation process in our database succeeds, but the finish operation fails to complete normally due to the user exiting the app or similar circumstances? Our assumption is that since the product is activated in our database, we can provide value for the charge without issue, and there is no deterioration in UX, such as the inability to process refunds in the app store. Are there any potential concerns or bugs that might arise? Regarding this inquiry, if you have any information—such as whether this scenario would result in a rejection during the app review process—we would appreciate it if you could share it with us.

Hello. I have a few questions about the implementation of Apple Pay payments on websites. Could you help me From the documentation: Apple Pay issues an Apple Pay Merchant Token if the user’s payment network supports merchant-specific payment tokens. Otherwise, Apple Pay issues a device token for the payment request. How can we determine whether a token is a merchant token or a device token? Is it possible to determine this by any of the token fields? https://developer.apple.com/documentation/passkit/payment-token-format-reference Is it possible to understand this in other ways? Can I make recurring payments with the device token if it was issued instead of the merchant token? Is it necessary to include the tokenNotificationURL when generating a merchant token, or can we generate one without specifying it? What does the applicationExpirationDate field in the merchant token represent? Is this the date when the device token or merchant token expires and payments cannot be made with it?
