App stuck no any Response from Mar 1
Hi everyone, My previous updates were usually processed within 24-48 hours, so I’m concerned if there might be an issue or if there's a general delay in the review queue. Should I continue to wait, or is it time to contact the App Review team directly or Shall i re-submit another build ? Has anyone else experienced similar delays recently?

User crash report contains ??? instead of my app's symbols and no binary image base address
A user of my app sent me a crash report. I have never seen one like this before. All of my app's symbols are replaced with three question marks (???) Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 ??? 0x10844eb40 ??? 1 CoreFoundation 0x7ff80f155518 __CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ + 137 and the binary image as 0x0 - 0xffffffffffffffff ??? (*) <00000000-0000-0000-0000-000000000000> ??? so I cannot find out where exactly the crash happened. What can cause this kind of crash report and can I do anything with it? crash.ips

How to Reload Collection View (DiffableDataSource) after API Finishes Calling
Hello, I have a collection view that uses a diffable data source, and I am initiating an API call while configuring a cell RuntimeCell in the cell registration block inside setupDataSource(). The cell has a runtimeLabel property whose text I am setting inside a configureLabel(movieId:) function. I noticed that the collection view does not automatically refresh the text label once this API call finishes and after setting the text property on a UILabel in the collection view cell to a value retrieved during the API call. I presume this is because I need to call dataSource.apply(snapshot) myself to reload the changes in the collection view after the API call finishes retrieving the runtime data. However, since the API call happens via the configuration of the cell in the cell registration closure, this API call ends up being called infinitely if I call dataSource.apply(snapshot) every time the API call finishes (i.e. calling dataSource.applySnapshot() calls the closure for the cell registration handler which re-triggers the API call). What is the correct architecture to apply to accomplish reloading the collection view so that the text label appears once the API finishes calling? Thank you class MovieDetailViewController: UIViewController { func setupDataSource() { // ... let runTimeCellRegistration = UICollectionView.CellRegistration<RuntimeCell, Item> { cell, indexPath, item in cell.runtimeLabelDelegate = self cell.configureLabel(movieId: self.selectedMovie.id) } dataSource = UICollectionViewDiffableDataSource(collectionView: collectionView, cellProvider: { collectionView, indexPath, itemIdentifier in let section = Section(rawValue: indexPath.section) switch section { //... case .runtime: return collectionView.dequeueConfiguredReusableCell(using: runTimeCellRegistration, for: indexPath, item: itemIdentifier) //... } return nil }) } } protocol RuntimeLabelCellDelegate: AnyObject { func didUpdateRuntime() } class RuntimeCell: UICollectionViewCell { var runtimeLabel: UILabel! //... UI Setup func configureLabel(movieId: Int) { Task { do { let details = try await movieSearchService.fetchMovieDetails(movieId: movieId) await MainActor.run { let minutes = details.runTime let durationText = "\(minutes)m" var emojiText = "" if minutes < 90 { emojiText = "Short & Sweet ⚡️" } else if minutes > 150 { emojiText = "Get the snacks ready 🍿" } runtimeLabel.text = emojiText.isEmpty ? durationText : "\(durationText) • \(emojiText)" runtimeLabelDelegate?.didUpdateRuntime() } } catch { print("Failed to load details: \(error)") } } } } extension MovieDetailViewController: RuntimeLabelCellDelegate { func didUpdateRuntime() { var snapshot = dataSource.snapshot() snapshot.appendItems([.runtime], toSection: .runtime) dataSource.apply(snapshot, animatingDifferences: true) } }

App Stuck in “Waiting for Review” for Over 3 Weeks (Since Feb 9)
Hello everyone, I am an iOS developer and both my apps are experiencing an unusual App Store review delay that I have not been able to resolve through the normal support channels. These are existing apps on app store with simple updates. It has not moved to “In Review”, and I have not received any rejection message or request for additional information from the App Review team. AppleID: 6756242440 and 6746870245 Please help us resolve the issue. Thanks in advance

RealityKit game keeps using ~65% CPU even with empty scene
I'm trying to convert my game from SceneKit to RealityKit. I noticed that even when the scene is static (nothing moves), RealityKit keeps using CPU. In SceneKit, CPU goes down to 0% with a static scene. With this simplest of games, RealityKit keeps using about 65% CPU: class ViewController: NSViewController { override func loadView() { view = ARView(frame: NSScreen.main!.frame) } } Is this expected or a bug? I created FB22125047.

How does AccessoryNotifications forward notifications to BLE accessories? What Service/Characteristic should the accessory implement?
Environment: iOS 26.4 beta Xcode 26.4 beta Framework: AccessoryNotifications, AccessorySetupKit, AccessoryTransportExtension Description: I'm implementing notification forwarding to a custom BLE accessory using the new AccessoryNotifications framework in iOS 26.4. I've set up an AccessoryDataProvider extension following the documentation, but I'm unclear about how the data is actually transmitted to the BLE accessory. Current Implementation: Main App - Uses AccessorySetupKit to discover and pair accessories: let descriptor = ASDiscoveryDescriptor() descriptor.bluetoothServiceUUID = CBUUID(string: "FEE0") let displayItem = ASPickerDisplayItem( name: "Notification Accessory", productImage: UIImage(systemName: "applewatch")!, descriptor: descriptor ) accessorySession.showPicker(for: [displayItem]) { error in // Handle error } AccessoryDataProvider Extension - Implements NotificationsForwarding.AccessoryNotificationsHandler: @main struct AccessoryDataProvider: AccessoryTransportExtension.AccessoryDataProvider { @AppExtensionPoint.Bind static var boundExtensionPoint: AppExtensionPoint { Identifier("com.apple.accessory-data-provider") Implementing { AccessoryNotifications.NotificationsForwarding { NotificationHandler() } } } } // NotificationHandler sends messages via: let message = AccessoryMessage { AccessoryMessage.Payload(transport: .bluetooth, data: data) } try await session?.sendMessage(message) Info.plist Configuration: EXExtensionPointIdentifier com.apple.accessory-data-provider NSAccessorySetupBluetoothServices FEE0 Questions: What BLE Service and Characteristic should the accessory advertise? - The documentation mentions specifying transport: .bluetooth, but doesn't explain what Service/Characteristic the accessory needs to implement to receive the notification data. 2. How does AccessoryMessage with transport: .bluetooth actually transmit data? - Is there a specific Apple-defined BLE protocol? - Does the accessory need to run specific firmware or support a particular protocol stack? 3. Is there any documentation about the accessory-side implementation? - The iOS-side documentation is clear, but I couldn't find information about what the BLE peripheral needs to implement. 4. Is MFi certification required for the accessory? - The documentation doesn't explicitly mention MFi, but it's unclear if custom third-party accessories can use this framework. Any guidance on how the BLE communication works under the hood would be greatly appreciated.

Core data destroyPersistentStore, not working for some
Hi all I have a problem with core data, where when a new user login that is different from the previous user i delete all of core data by using "destroyPersistentStore". Then i recreate the persistent store, this works when i am testing. When it does not work for one of my users when she test. I am not sure why this should not work, i have added the code i use to destroy the persistent store below. This code is run after login but before the view changes away from my login view. // Retrieves the shared `AppDelegate` instance guard let appDelegate = UIApplication.shared.delegate as? AppDelegate else { return } appDelegate.destroyDataSyncBackground() // Get a reference to a NSPersistentStoreCoordinator let storeContainer = appDelegate.persistentContainer.persistentStoreCoordinator // Delete each existing persistent store for store in storeContainer.persistentStores { if let url = store.url { do { try storeContainer.destroyPersistentStore( at: url, ofType: store.type, options: nil ) } catch { print("Failed to deleted all") } } else { print("Failed to deleted all") } } // Re-create the persistent container appDelegate.persistentContainer = NSPersistentContainer( name: "CueToCue" // the name of // a .xcdatamodeld file ) // Calling loadPersistentStores will re-create the // persistent stores appDelegate.persistentContainer.loadPersistentStores { (store, error) in // Handle errors let description = NSPersistentStoreDescription() description.shouldMigrateStoreAutomatically = true description.shouldInferMappingModelAutomatically = true appDelegate.persistentContainer.persistentStoreDescriptions = [description] } // Reapply context configuration let viewContext = appDelegate.persistentContainer.viewContext viewContext.automaticallyMergesChangesFromParent = true viewContext.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy do { try viewContext.save() appDelegate.recreateDataSyncBackground() } catch { print("Debug: saving delete all failed.") } } The function "destroyDataSyncBackground" just set the my sync class to nil so stop any changes to core data while the code is running. The function "recreateDataSyncBackground" recreate the sync class so fetch, post and patch requests is made again.

StoreKit1: finishTransaction fails to work as expected in iOS 26.4
Our game application is developed based on StoreKit 1, and an exception occurs on iOS 26.4: after players complete a payment, the finishTransaction method fails to properly remove the transaction from the SKPaymentQueue; as a result, when players restart the app, the system still triggers the retry process for this transaction (reconciliation of unpaid orders). Has anyone encountered this issue? If there is a solution, we would appreciate it if you could share it with us.

AVAssetDownloadConfiguration: How many video variants are actually downloaded when multiple variants exist in the HLS master playlist?
Hi, I’m trying to better understand how AVAssetDownloadConfiguration selects video variants when downloading HLS content for offline playback. Suppose I have an HLS master playlist (.m3u8) that contains several video variants defined with #EXT-X-STREAM-INF. For example, the master playlist may contain multiple video streams like this: Same resolution, different BANDWIDTH Or different resolutions (for example 720p, 1080p, etc.) My question is: How many video variants are actually downloaded when using AVAssetDownloadConfiguration without specifying any variantQualifiers? In other words: If the master playlist contains multiple video variants, will the download task fetch only one variant, or multiple variants? Does the behavior differ depending on whether the variants differ only by BANDWIDTH or also by RESOLUTION? What I observed in testing In my tests, I always end up with only one video variant downloaded, specifically the one with the highest BANDWIDTH parameter. In the m3u8 files I tested, all video variants had identical parameters (resolution, codec, frame rate, etc.) and differed only by the BANDWIDTH attribute in the master playlist. However, when inspecting the downloaded .movpkg, I noticed something interesting in boot.xml. It lists two video streams: one with complete="true" (the one with highest bandwidth) another with complete="no" (the one with lowest bandwidth) I actually had 3 video streams listed in m3u8, but the one with middle bandwidth wasn't listed in boot.xml file at all. There are also additional streams for audio and subtitles in boot.xml file. This made me wonder whether the system initially attempts to download another video variant (possibly a lower bitrate one), but then switches to the highest-quality variant and only completes that one. Additional question about variantQualifiers If I provide a predicate such as: NSPredicate(format: "peakBitRate > 0") which should theoretically match all variants, will the download task attempt to download all matching video variants, or will it still select only one? Summary So the main questions are: Without variantQualifiers, does AVAssetDownloadConfiguration always download a single video variant, and if so, how is it chosen? Does the behavior differ if variants have different resolutions vs only different bitrates? When a predicate matches multiple variants, can multiple video variants actually be downloaded in a single .movpkg? Why might boot.xml list multiple video streams when only one appears to be fully downloaded? Any clarification on the intended behavior would be greatly appreciated. Thanks!

In the iOS 26.4 beta version of WKWebView, it is impossible to establish an IP type WebSocket connection!
In iOS 26.4 beta, I noticed that when loading pages using WKWebView and using WebSocket to establish IP type addresses, the connection duration was several seconds and sometimes even failed to connect (normally, the connection duration should be in milliseconds). However, when establishing WebSocket connections using domain names, the connections were normal. Additionally, I discovered a special scenario: When directly establishing WebSocket connections using IP type addresses, it remained in the "connect" state. At the same time, based on Wireshark packet capture, it was found that no TCP connection was sent at this time. However, if two connections with the same address were established simultaneously, those two connections could successfully connect. This bug has seriously affected the use of my application service. Is there a chance that this version will solve the problem?

Validation error with Network Extension due to square brackets in Product Name
Hello, I am facing a validation error when uploading a macOS app with a Network Extension. The Error: Invalid system extension. The system extension at “[T] TEXT.app/Contents/Library/SystemExtensions/company_name.network-extension.systemextension” resides in an unexpected location. The Problem: Validation fails only when the app's Product Name contains square brackets: [T] TEXT. If I remove the brackets from the Product Name, validation passes. What I've tried: Setting Product Name to TEXT (without brackets) and CFBundleDisplayName to [T] TEXT. Cleaning Derived Data and rebuilding the archive. Verified that the extension is physically located at Contents/Library/SystemExtensions/. It seems the Apple validation tool fails to parse the bundle path correctly when it contains characters like [ or ]. Question: How can I keep the app name with brackets for the user (in System Settings and Menu Bar) while ensuring the Network Extension passes validation? Is there a way to escape these characters or a specific Info.plist configuration to satisfy the validator?"
