Hi everyone 👋 I’m running into a persistent SSL issue on iOS where the app fails to establish a secure HTTPS connection to our backend APIs. The same endpoints work fine on Android and web, but on iOS the requests fail with: Error Domain=NSURLErrorDomain Code=-1200 "An SSL error has occurred and a secure connection to the server cannot be made." UserInfo={ NSLocalizedDescription = "An SSL error has occurred and a secure connection to the server cannot be made."; _kCFStreamErrorDomainKey = 3; _kCFStreamErrorCodeKey = -9802; } 🔍 What I’ve Checked: The servers use valid, trusted SSL certificates from a public CA TLS 1.2 and 1.3 are enabled The intermediate certificates appear correctly configured (verified using SSL Labs) The issue happens on our customer's end. (Got it via Sentry) Note: We recently removed NSAppTransportSecurity(NSAllowsArbitraryLoads) on our app, since all the endpoints use valid HTTPS certificates and standard configurations. ❓ Questions: Are there additional SSL validation checks performed by iOS when ATS is enabled? Has anyone seen similar behaviour, where valid certificate chains still trigger SSL errors? Any insights or debugging suggestions would be greatly appreciated 🙏

Hi, We began to get this new crash in codes that exist years ago from our recent released version, it crashed after a view removed itself from superview. We tried to look at the assembly code of NSISSparseVectorAddTermWithPlaceValueCoefficientStartingIndex, find out that d0 <= 0 would branch to NSISSparseVectorAddTermWithPlaceValueCoefficientStartingIndex.cold.1. We believe that it's related with Autolayout, but setting a negative value for width or height constraints can't reproduce this crash.

In the Keynote/Numbers/Pages apps for iPhone, there is a Help menu item for presenting a Help modal view. The view has a button for showing the hierarchical table of contents, and a field for searching the Help pages. How is such a Help modal view built through SwiftUI ? In which format is the Help content stored ?

I would like to know whether BGContinuedProcessingTaskRequest supports executing asynchronous tasks internally, or if it can only execute synchronous tasks within BGContinuedProcessingTaskRequest? Our project is very complex, and we now need to use BGContinuedProcessingTaskRequest to perform some long-running operations when the app enters the background (such as video encoding/decoding & export). However, our export interface is an asynchronous function, for example video.export(callback: FinishCallback). This export call returns immediately, and when the export completes internally, it calls back through the passed-in callback. So when I call BGTaskScheduler.shared.register to register a BGContinuedProcessingTask, what should be the correct approach? Should I directly call video.export(nil) without any waiting, or should I wait for the export function to complete in the callback? For example: BGTaskScheduler.shared.register(forTaskWithIdentifier: "com.xxx.xxx.xxx.xxx", using: nil) { task in guard let continuedTask = task as? BGContinuedProcessingTask else { task.setTaskCompleted(success: false) return } let scanner = SmartAssetsManager.shared let semaphore = DispatchSemaphore(value: 0) continuedTask.expirationHandler = { logError(items: "xwxdebug finished.") semaphore.signal() } logInfo(items: "xwxdebug start！") video.export { _ in semaphore.signal() } semaphore.wait() logError(items: "xwxdebug finished！") }

Good day, I've uploaded a build to TestFlight, but received an automated response with the following error: ITMS-90426: Invalid Swift Support - The SwiftSupport folder is missing. Rebuild your app using the current public (GM) version of Xcode and resubmit it. Our project started in Objective-C and have mixed swift class and pods. The last uploaded build without any automated response was Nov 8, 2023. I'm using XCode Version 26.0.1 (17A400). I've tried every way i found in internet and i'm not able to find any solution for this. ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = YES use_frameworks! :linkage => :dynamic (in pods) We would appreciate any assistance in clarifying why this issue is occurring and how we should proceed to address it. Your guidance would mean a lot. Thank you.

I’m developing an app that includes a navigation bar with a centered title and a single right bar button item. I’ve noticed that when both the navigation bar title and the right bar button item’s title are relatively long, the navigation bar title becomes hidden. This issue only occurs on iOS 26. When running the same code on iOS 18, the layout behaves as expected, with both elements visible. Has anyone else experienced this behavior on iOS 26? Is this a known layout change or a possible bug?

iPhone12 ， iOS26 NFCTagReaderSession cannot read NFCTagTypeISO7816Compatible anymore

Hello, I understand that to discover and pair a device or accessory with Wi-Fi Aware, we can use either the DeviceDiscoveryUI or AccessorySetupKitUI frameworks. During the pairing process, both frameworks prompt the user to enter a pairing code. Is this step mandatory? What alternatives exist for devices or accessories that don't have a way to communicate a pairing code to the user (for example, devices or accessories without a display or voice capability)? Best regards, Gishan

I am using a Raspberry Pi 5 (BLE 5.0) to read sensor data and send it via D-Bus and BlueZ to a Flutter application (flutter_blue_plus) for both iOS and Android. The goal is to display these real-time sensor updates directly on the device. On Android, the data transmission is immediate and the real-time visualization is extremely smooth and fast. However, on iOS, both BLE write and notification commands appear with noticeable latency—not only in real-time displays, but also when comparing ordinary notification feedback between the Raspberry Pi terminal and the iOS app. It seems that iOS buffers several BLE packets internally and then dispatches them in batches, which always introduces an additional delay. Additional setup details: I sample and transmit data every 25ms, sending binary packets of 20 bytes (length shouldn’t be a limiting factor). On the iOS side I am using an iPhone 15 Pro with iOS 18.6.2 (BLE 5.3). The Raspberry Pi (using btmon for logging) confirms after connection setup that the connection interval is fixed at 30ms (and cannot be changed). I have tried sending BLE packets every 30ms so that exactly one packet arrives per interval, but this made no difference—the latency and batch delivery remain. Interestingly, faster transmission rates (e.g. sending every 10ms) make the real-time display look smoother on iOS, but the guaranteed overall system latency does not improve. Also these methods used: write-without-response, using app in release modus (no debugging) Is there anyone familiar with this problem or a potential solution? Or is iOS simply not optimized for true real-time BLE data streaming and visualization? Any pointers, technical insights or workarounds would be greatly appreciated.

I have the main app that saves preferences to UserDefaults.standard. So I have this one preference that the user is able to toggle - isRawOn UserDefaults.standard.set(self.isRawOn, forKey: "isRawOn") Now, I have LockedCameraCaptureExtension which is required know if that above setting on or off during launch. Also if it's toggled within the extension, the main app should know about it on the next launch. The main app and the extension runs on separate containers and the preferences are not shared due to privacy reasons. Apple mentions of using appContext of CameraCaptureIntent, but not sure how above scenario is possible through that....unless I am missing something. Apple Reference What I have for CameraCaptureIntent: @available(iOS 18, *) struct LaunchMyAppControlIntent: CameraCaptureIntent { typealias AppContext = MyAppContext static let title: LocalizedStringResource = "LaunchMyAppControlIntent" static let description = IntentDescription("Capture photos with MyApp.") @MainActor func perform() async throws -> some IntentResult { .result() } }

When my Bluetooth peripheral device has both HID and MIDI services, the iOS Bluetooth host repeatedly sends different "Control Opcode: LL_CONNECTION_UPDATE_IND" to the peripheral, updating approximately every 100ms. The Bluetooth peripheral cannot handle such high-frequency update requests and typically disconnects with an error 0x28. My Bluetooth device uses the NRF52832 chip, and I have communicated with NORDIC and replicated this issue. This problem only occurs on iOS 26; it does not happen on earlier versions. I think it might be caused by the HID service in iOS requesting faster connection parameters for low latency, which then gets erroneously reverted for an unknown reason, leading to repeated competition and entering into a deadlock. Here is the communication record with NORDIC: https://devzone.nordicsemi.com/f/nordic-q-a/124994/ios-26-bluetooth-disconnect-issues This is the screenshot captured using the Bluetooth sniffer:

Starting with iOS 18, UITabBarController no longer updates tab bar item titles when localized strings are changed or reassigned at runtime. This behavior worked correctly in iOS 17 and earlier, but in iOS 18 the tab bar titles remain unchanged until the app restarts or the view controller hierarchy is reset. This regression appears to be caused by internal UITabBarController optimizations introduced in iOS 18. Steps to Reproduce Create a UITabBarController with two or more tabs, each having a UITabBarItem with a title. Localize the tab titles using NSLocalizedString(): tabBar.items?[0].title = NSLocalizedString("home_tab", comment: "") tabBar.items?[1].title = NSLocalizedString("settings_tab", comment: "") Run the app. Change the app’s language at runtime (without restarting), or manually reassign the localized titles again: tabBar.items?[0].title = NSLocalizedString("home_tab", comment: "") tabBar.items?[1].title = NSLocalizedString("settings_tab", comment: "") Observe that the tab bar titles do not update visually.

On iOS 26.1, this throws on the 2020 iPad Pro (4th gen) but works fine on an M4 iPad Pro or iPhone 15 Pro: guard let device = AVCaptureDevice.default(.builtInLiDARDepthCamera, for: .video, position: .back) else { throw ConfigurationError.lidarDeviceUnavailable } It's just the standard code from Apple's own sample code so obviously used to work: https://developer.apple.com/documentation/AVFoundation/capturing-depth-using-the-lidar-camera Does it fail because Apple have silently dumped support for the older LiDAR sensor used prior to the M4 iPad Pro, or is there another reason? What about the 5th and 6th gen iPad Pro, does it still work on those?

On this page: https://developer.apple.com/documentation/storekit/testing-age-assurance-in-sandbox It says: Start with a Sandbox account. What is a Sandbox account and how does one set one up? Just it just simply mean an Apple account id used for testing, or something else?

I am developing an IOS App that allow users to scan rooms, view the scans on device, and add notes. I need to preserve actual geometry (odd angles, chamfers, fixtures), not simplified RoomPlan boxes. Are there any easy ways to incorporate high quality texture mapping or PBR? Where is the documentation for scene reconstruction?

For a long time our app had this creation of a URLRequest: var urlRequest = URLRequest(url: url, cachePolicy: .reloadIgnoringLocalAndRemoteCacheData, timeoutInterval: timeout) But since iOS 26 was released we started to get crashes in this call.

Light shining effects can repeatedly be observed on older iPhone devices (12/13/14). This change is often seen after the device is rebooted or after a SystemMemoryReset.ips (System Analysis Data). It changes very often...

I've being playing aground with long press gesture in scroll view and noticed gesture(LongPressGesture()) doesn't seem to work with scroll view's scrolling which doesn't seem to be the intended behavior to me. Take the following example: the blue rectangle is modified with onLongPressGesture and the red rectangle is modified with LongPressGesture (_EndedGesture<LongPressGesture> to be specific). ScrollView { Rectangle() .fill(.blue) .frame(width: 200, height: 200) .onLongPressGesture { print("onLongPressGesture performed") } onPressingChanged: { _ in print("onLongPressGesture changed") } .overlay { Text("onLongPressGesture") } Rectangle() .fill(.red) .frame(width: 200, height: 200) .gesture(LongPressGesture() .onEnded { _ in print("gesture ended") }) .overlay { Text("gesture(LongPressGesture)") } } If you start scrolling from either of the rectangles (that is, start scrolling with your finger on either of the rectangles), the ScrollView will scroll. However, if LongPressGesture is modified with either onChanged or .updating, ScrollView won't respond to scroll if the scroll is started from red rectangle. Even setting the maximumDistance to 0 won't help. As for its counter part onLongPressGesture, even though onPressingChanged to onLongPressGesture, scrolling still works if it's started from onLongPressGesture modified view. ScrollView { Rectangle() .fill(.blue) .frame(width: 200, height: 200) .onLongPressGesture { print("onLongPressGesture performed") } onPressingChanged: { _ in print("onLongPressGesture changed") } .overlay { Text("onLongPressGesture") } Rectangle() .fill(.red) .frame(width: 200, height: 200) .gesture(LongPressGesture(maximumDistance: 0) // scroll from the red rectangle won't work if I add either `updating` or `onChanged` but I put both here just to demonstrate // you will need to add `@GestureState private var isPressing = false` to your view body .updating($isPressing) { value, state, transaction in state = value print("gesture updating") } .onChanged { value in print("gesture changed") } .onEnded { _ in print("gesture ended") }) .overlay { Text("gesture(LongPressGesture)") } } This doesn't seem right to me. I would expect the view modified by LongPressGesture(), no matter if the gesture has onChanged or updating, should be able to start scroll in a scroll view, just like onLongPressGesture. I observed this behavior in a physical device running iOS 26.1, and I do not know the behavior on other versions.
