Our app provides a calendar that integrates with the default calendar app. Specifically, we use iOS EventKit to perform CRUD operations on calendar data. Recently, we have received reports from users that all of their events have disappeared. However, after reviewing our implementation and logs, we have not been able to identify the cause. Some users have also reported that all data in their default calendar app has disappeared as well. Does anyone have any idea what might be causing this? To delete an event within our app, users must press the delete button and then confirm the deletion in a dialog. Additionally, it is not possible to delete more than two events at once. We've seen many people in the community discussing a bug where calendar events disappear after updating to iOS 18. If you have any information about when or why this happens, we'd appreciate it if you could share your insights.

For years our iOS apps have experienced a networking problem, which blocks them connecting to our servers via their API endpoint domains. How can we recover after the scenario described below? Using 3rd party error logging solutions, which have different endpoint domains, we can record the error: NSUnderlyingError": Error Domain=kCFErrorDomainCFNetwork Code=-1200 "(null)" UserInfo={_kCFStreamPropertySSLClientCertificateState=0, _kCFNetworkCFStreamSSLErrorOriginalValue=-9816, _kCFStreamErrorDomainKey=3, _kCFStreamErrorCodeKey=-9816, _NSURLErrorNWPathKey=satisfied (Path is satisfied), viable, interface: pdp_ip0[lte], ipv4, dns, expensive, uses cell}, "_NSURLErrorFailingURLSessionTaskErrorKey": LocalDataTask <DEDBFA4D-810D-4438-A6A0-95E3B9668B9E>.<308>, "_kCFStreamErrorDomainKey": 3, "_NSURLErrorRelatedURLSessionTaskErrorKey": <__NSSingleObjectArrayI 0x301f82e60>( LocalDataTask <DEDBFA4D-810D-4438-A6A0-95E3B9668B9E>.<308> ) "NSLocalizedDescription": An SSL error has occurred and a secure connection to the server cannot be made., "NSLocalizedRecoverySuggestion": Would you like to connect to the server anyway? -9816 is the "server closed session with no notification" error based on comments in CoreFoundation source files. Subsequent API endpoint calls to the same domain return the same error. The SSL error occurs most prevalently after a server outage. However, despite our best efforts, we have been unable to replicate triggering the problem for development purposes via experiments with our server. When the error occurs the users report that: Fully closing (i.e. not just sending to background) and reopening the app does NOT clear connectivity to our server being blocked. Problem seems more prevalent when using mobile/cell data. Switching from mobile/cell data to WIFI resolves the connection problem and then switching back to mobile/cell data shows the problem again. So the underlying problem is not cleared. All other apps on the same device and mobile/cell data or WIFI connection, like Safari, have no problems connecting to the Internet. Deleting and reinstalling, or updating (when an update is available) resolves the problem. Or after waiting a few days the problem seems to resolve itself. The last two point above suggest that something is persisted/cached in the app preventing it from connecting properly with subsequent network attempts. Notes: We have one shared instance of the URLSession in the app for its networking because we are aware of the perils of multiple URLSession instances. We recently added conditions to call the URLSession await reset() method when detecting the SLL errors before repeating the request. It is debatable whether this reduces the problem as we still see logged cases with the subsequent requests hitting the same -9816 error. URLSession configuration: let config = URLSessionConfiguration.default config.timeoutIntervalForResource = 22 config.timeoutIntervalForRequest = 20 config.requestCachePolicy = .reloadIgnoringLocalCacheData config.urlCache = nil

I am pretty sure iOS 13.4 (beta and later) did support Coded PHY (Long Range). Tested devices are iPhone SE2 and iPhone 11 Pro. However, it seems iOS 14 removed the support of Coded PHY, accidentally or on purpose, I don't know? The same PHY update request returns "1M PHY" in iOS 14, but "Coded PHY" in iOS 13 (13.4 beta and later). Anyone knows why? Samson

Hello, I use Storekit2 to test the purchase of subscription products. After purchasing a subscription product in the sandbox, it will automatically renew 12 times, and then it will no longer automatically renew. When I click to purchase again, calling the try await product.purchase() method does not pop up the purchase pop-up window. In fact, it will directly go to the case let .success(.verified(transaction)): step, and the Transaction.currentEntitlements is empty

I have added an "App Intents Extension" target to my main application in macOS. This generated the below two files: TWAppIntent.swift import AppIntents struct TWAppIntent: AppIntent { static var title: LocalizedStringResource = "TWAppIntentExtension" static var parameterSummary: some ParameterSummary { Summary("Get information on \(\.$TWType)") } //launch app on running action static var openAppWhenRun: Bool = true // we can have multiple parameter of diff types @Parameter(title: "TWType") var TWType: String func perform() async throws -> some IntentResult & ReturnsValue<String> & ProvidesDialog { return .result(value: TWType, dialog: "Logged break.") } } TWAppIntentExtension.swift import AppIntents @main struct TWAppIntentExtension: AppIntentsExtension { } I m able to build the extension target and I my intent action is available in the shortcuts app. However, on launching a shortcut with the above created intent action. I m getting the below popups: I have identified what is causing this error. Setting the openAppWhenRun to true is causing this error. I don't get this when it is set to false. This property is supposed to launch the application, but can someone help me understand why is it happening? This is only causing the error when using this property for AppIntent Extension and not for In app handling for the AppIntent. Can we not launch our application from AppIntent extension?

Hello developers, We're facing a critical issue with our app and need your insights: Since today, 3 specific IAP products return empty data when calling Product.products(for: [productId]). This affects all users, preventing any successful purchases of these items. Other IAP products seem unaffected. let products = try await Product.products(for: [productId]) Key details: Production environment Issue started: 2025.6.17 No recent app updates All products show as "Approved" in App Store Connect Questions: Has anyone experienced similar issues recently? Could this be a StoreKit or App Store system problem? Any suggestions for diagnosing or resolving this, besides contacting Apple Support? Recommendations for temporary workarounds? This is severely impacting our business. Any help is greatly appreciated! Thank you!

Hello, I’m building a health-related app for both watchOS and iOS, which needs to monitor certain health data (e.g., heart rate, active energy). Before updating to watchOS 26, the queries worked reliably without any issues. However, after adapting to watchOS 26, some users have reported that health data updates stop being delivered. What I’ve observed: HKObserverQuery with enableBackgroundDelivery is set up normally. On WatchOS 26, the query sometimes stops delivering updates entirely after a certain point, and once an update is missed, it may stop delivering further updates completely. Restarting the Apple Watch temporarily restores delivery, but the problem reoccurs after some time. This makes background health data monitoring unreliable for my app. Here’s a simplified version of the code we are using: guard let heartType = HKObjectType.quantityType(forIdentifier: .heartRate) else { return } let query = HKObserverQuery(sampleType: heartType, predicate: nil) { query, completionHandler, error in if let error = error { logEvent("Observer error: \(error.localizedDescription)") return } logEvent("Heart rate changed") MyNotificationManager.shared.sendNotification() // Send a local notification completionHandler() } healthStore.execute(query) healthStore.enableBackgroundDelivery(for: heartType, frequency: .hourly) { success, error in if success { logEvent("Background heart rate delivery enabled") } else { logEvent("Failed to enable background heart rate delivery: \(error?.localizedDescription ?? "Unknown error")") } } Could you please clarify: Is this a known issue with HKObserverQuery and enableBackgroundDelivery on watchOS 26? Are there any recommended workarounds or best practices to ensure continuous background delivery of health data? Thank you in advance for your help.

We're seeing a consistent issue where iPads with the A16 chip fail to connect to our BLE device, which uses a Silicon Labs chip running Gecko SDK 3.x. All other Apple devices — including older iPads and iPhones — connect without any problems. According to Silicon Labs, the issue stems from the iPad A16 sending an LL_CHANNEL_REPORTING_IND message (opcode 0x28) during connection establishment: Per Silicon Labs: "Currently the iPad 16 will send a message for LL_CHANNEL_REPORTING_IND (opcode 0x28). This is a feature that is not supported in Gecko SDK 3.x. Shortly after, the BLE module responds with an 'Unknown Response' (opcode 0x07), indicating that it does not support opcode 0x28 After this exchange the iPad stops sending meaningful transactions to the BLE module and eventually closes the connection. The BLE Module is responding to this unknown request as specified in the BT Core Spec Volume 6 Part B." Unfortunately, the firmware on these BLE modules cannot be updated remotely, and we've already shipped several thousand units to customers. Given how widely Silicon Labs' BLE modules are deployed, we suspect this issue could be affecting many other developers and products as well. We’re hoping Apple might offer a workaround or allow us access — even internally or unofficially — to suppress or bypass this feature in CoreBluetooth for this specific scenario. For example, is there a way to disable LL_CHANNEL_REPORTING_IND or instruct the stack to ignore the unknown response from the peripheral? We’re open to any workaround via CoreBluetooth (even private APIs or entitlements, if necessary) that would allow us to preserve compatibility without a mass recall. If there's an Apple engineer monitoring this, we'd be extremely grateful for guidance or escalation. Thank you!

Hello. I have a problem with update check ! Say “ error to Check update” update section on my iPhone 16 pro. what Is the solution to fix?

when I go to software and update it says can’t check for updateS.

I have an iPhone 14 Pro. I downloaded the iOS 26 beta and had a SERIOUS error, rendering the phone unusable. I charged it to 60% and kept it plugged in while updating. While updating, I restarted several times at the Apple logo, then at the Welcome screen, and it had quite a few bugs with low battery warnings. When I turned it on, I noticed I had 1% (I thought it was strange). When it was plugged in, it wouldn't charge; it only had 1% left, and it also restarted every 2 minutes. Off-plugged, it did exactly the same thing. In the end, I had to go back to iOS 18.5; I had no problems with this version.

Hi, I'm working with the new FSKit framework and have successfully implemented a custom file system using FSUnaryFileSystem. Mounting the file system via Terminal works perfectly — I can create, delete, and browse files and directories as expected. Since /Volumes is protected on modern macOS systems, I cannot mount my file system there directly. Instead, I mount it into a different writable directory (e.g., /tmp/MyFS) and then create a symbolic link to it in a user-visible location such as ~/Downloads/MyFS. Finder does see the symlink and displays it with a "Volume" icon, but clicking it results in an error — it cannot be opened. It seems like Finder does not treat the symlinked mount as a fully functional volume. Is there a proper way to register or announce a FSKit-mounted file system so that Finder lists it as a real volume and allows access to it? Are there additional steps (APIs, notifications, entitlements, or Info.plist keys) required to integrate with Finder? Any insight would be greatly appreciated. Thanks!

I have a strange crash which I have problems understanding. It only happens on a few devices, after a ModelContainer migration, and it doesn't seem to crash on the migration itself. The fetch is done in onAppear, and shouldn't necessarily result in a crash, as it is an optional try: let request = FetchDescriptor<Rifle>() let data = try? modelContext.fetch(request) if let data, !data.isEmpty { rifle = data.first(where: { $0.uuid.uuidString == settings.selectedRifleId }) ?? data.first! } When I get logs from users, there seems to be an error in encoding?

I recently encountered an issue with Xcode 16.2 while attempting to integrate Settings.bundle into a new app. I added Settings.bundle as a new file (using the provided template), but when I ran the app (the default "Hello World" project), the expected three default controls (Name, Enabled, Slider) did not appear in the app's settings. To troubleshoot, I downgraded my system to macOS Sonoma 14.7.2 and Xcode 15.4 (on a 2023 Mac Mini, M2). After this downgrade, everything worked as expected. With a new project, adding Settings.bundle, and running the app, the settings entry for the app appeared, including the three default fields. This behavior suggests a potential issue or incompatibility with Xcode 16.2.

In IOS17 and IOS18, core spotlight can only match app contents by searching for the displayName, but cannot hit the contents by using keywords. Moreover, when matching the app content by searching for the "displayName", it requires inputting four consecutive characters to achieve a match.These issues did not occur in iOS 16. What is the reason for this? Here is my code. func addItemToIndex(_ item: QSpotlightItem) { let attributeSet = CSSearchableItemAttributeSet(contentType: .item) attributeSet.title = item.title attributeSet.displayName = item.title attributeSet.contentDescription = item.contentDescription attributeSet.keywords = item.keywords attributeSet.thumbnailData = item.thumbnailImage attributeSet.contactKeywords = item.keywords attributeSet.supportsNavigation = true let searchableItem = CSSearchableItem(uniqueIdentifier: item.id, domainIdentifier: "xxx", attributeSet: attributeSet) searchableItem.expirationDate = .distantFuture CSSearchableIndex.default().indexSearchableItems([searchableItem]) { error in if let error = error { } else { } } }

When installing a new version the app while a tunnel is connected, seemingly the old packet tunnel process gets stopped but the new one does not come back up. Reportedly, a path monitor is reporting that the device has no connectivity. Is this the expected behavior? When installing an update from TestFlight or the App store, the packet tunnel instance from the old tunnel is stopped, but, due to the profile being on-demand and incldueAllNetworks, the path monitoring believes the device has no connectivity - so the new app is never downloaded. Is this the expected behavior? During development, the old packet tunnel gets stopped, the new app is installed, but the new packet tunnel is never started. To start it, the user has to toggle the VPN twice from the Settings app. The tunnel could be started from the VPN app too, if we chose to not take the path monitor into account, but then the user still needs to attempt to start the tunnel twice - it only works on the second try. As far as we can tell, the first time around, the packet tunnel never gets started, the app receives an update about NEVPNStatus being set to disconnecting yet NEVPNConnection does not throw. The behavior I was naively expecting was that the packet tunnel process would be stopped only when the new app is fully downloaded and when the update is installed, Are we doing something horribly wrong here?

PDFKit PDFPage.characterBounds(at: Int) is returning incorrect coordinates with iOS 18 beta 4 and later / Xcode 16 beta 4. It worked fine in iOS 17 and earlier (after showing the same issue during the early iOS 17 beta cycle) It breaks critical functionality that my app relies on. I have filed feedback (FB14843671). So far no changes in the latest betas. iOS release date is approaching fast! Anybody having the same issue? Any workaround available?

I have added a Network Extension to my iOS project to use the WireGuard library. Everything was working fine up to Xcode 16, but after updating, I’m facing a build issue. The build fails with the following error: No such file or directory: '@rpath/WireGuardNetworkExtensioniOS.debug.dylib' I haven’t explicitly added any .dylib to my project. The Network Extension target builds and runs fine on Xcode 16.

Recently, some feedback has been received. After users upgrade to ipados 17.7.7 and return to the login status and restart the App, it will become invalid. We checked the log and found that the content stored in NSUserdefault would be lost after restarting the App. Has anyone encountered this problem?

As a part of the video editing app I’m working on, I want to efficiently copy a folder of resources on the same (local) filesystem. Because iOS is on APFS, cloning (CoW) is an option. I read the documentation for clonefile(2) which states that cloning a folder works but is strongly discouraged. I did a small sample project which demonstrates that using clonefile on a folder works correctly and is 10× faster than using FileManager’s copyItem method. My questions: The main one I’m interested in: Why is using clonefile for a folder strongly discouraged? Is FileManager using cloning behind the scenes? Or more exactly how guaranteed are we it will use it? (I know it does, I tried manually cping the resources and it was thousands of times slower.)
