iOS SMS OTP AutoFill without clicking the keyboard suggestion
Hi Apple, Currently we want to have enhancement for SMS OTP that we want to implement OTP Autofill, But after do some research we're stuck with option that the OTP only show in keyboard suggestion, is there any way for making OTP is automatically filled without user have to click the keyboard suggestion when receiving the SMS. Thanks Best Regards, Admiral Sultano Harly.

Is “webcredentials” required for HTTPS callbacks in ASWebAuthenticationSession?
Hello, When using ASWebAuthenticationSession with an HTTPS callback URL (Universal Link), I receive the following error: Authorization error: The operation couldn't be completed. Application with identifier jp.xxxx.yyyy.dev is not associated with domain xxxx-example.go.link. Using HTTPS callbacks requires Associated Domains using the webcredentials service type for xxxx-example.go.link. I checked Apple’s official documentation but couldn’t find any clear statement that webcredentials is required when using HTTPS callbacks in ASWebAuthenticationSession. What I’d like to confirm: Is webcredentials officially required when using HTTPS as a callback URL with ASWebAuthenticationSession? If so, is there any official documentation or technical note that states this requirement? Environment iOS 18.6.2 Xcode 16.4 Any clarification or official references would be greatly appreciated. Thank you.

Question about testing the Declared Age Range feature
I’m integrating the Declared Age Range feature to tailor our app’s experience based on a user’s age range. I’m currently in the testing phase and would like to repeatedly test the consent flow and different outcomes from AgeRangeService.shared.requestAgeRange(...). However, once I go through the consent flow and choose to share, the age-range sharing sheet no longer appears on subsequent attempts—so it’s hard to validate edge cases (e.g., changed gates, declined flow, re-prompt behavior). Could you advise on the recommended way to reset or re-prompt during development? In particular: Is there a supported way to clear per-app consent so the system prompts again? Under what conditions should the “Share Age Range Again” control appear in Settings, and is there an equivalent way to trigger it for testing? Are there best practices for QA (e.g., using Ask First at the system level, testing on real devices vs. Simulator, using a separate bundle ID for dev builds, or other steps)? Any other guidance for validating different requestAgeRange results (e.g., declined/not available) would be appreciated.

The relationship between age verification and permission kit isn't clear (IMO)
I'm trying to digest and understand the new set of APIs relating age verification that were released last week. I have say that without some cohesive overview, example app, just a simple diagram showing the relationship of everything, its not at all clear to me what's going on nor what an app developer is expected to do to use these apis (I'm a senior engineer with 15 year's iOS experience, but hey maybe I'm just a bit slow in the head). I have a few questions, but the topic of this post is what is the relationship between age verification i.e. between the declared age range/significant change and Permission Kit? The documentation for the former mentions the Significant Change API/Topic (https://developer.apple.com/news/?id=2ezb6jhj / https://developer.apple.com/documentation/PermissionKit/SignificantAppUpdateTopic). Now the Significant Change Topic is documented as being part of PermissionKit, however the documentation for that (https://developer.apple.com/documentation/permissionkit) States emphatically at the top: "Communication experiences using the PermissionKit framework are only available using iMessage." Meaning you can't use PermissionKit for anything other than iMessage? If it doesn't mean that, then why does it state so? If it does mean that, then how does an app which has nothing to do with iMessage make use of Significant Change - because this documentation:https://developer.apple.com/news/?id=2ezb6jhj Is talking about using significant change for all apps, not iMessage. So there is a contradiction here.

iOS 26: cells overlap in UICollectionView orthogonal scrolling section after zoom transition
I have a UICollectionView using a UICollectionViewCompositionalLayout with an orthogonally scrolling section. When selecting a cell, I present a modal view controller with a zoom transition. If I scroll quickly in that section after dismissing the presented view controller, the cells briefly overlap. See the attached screenshot. This issue occurs only on iOS 26 and does not occur on iOS 18. Has anyone found a way to mitigate this? Sample project: https://github.com/antiraum/iOS26_UICollectionViewZoomTransitionIssue Feedback FB21022192

Xcode 26.1.1 related issue.
I’m experiencing an issue after building the project with Xcode 26.1.1. In my code, I have a UICollectionView that contains multiple cells, and each cell has a slider. When I move a slider in one cell, sliders in other cells also move. This issue does not occur in Xcode 16.4 – it works perfectly there. If anyone has a solution or knows if this is related to Xcode 26 changes, please let me know. Thanks!

iOS BGProcessingTask + Background Upload Not Executing Reliably on TestFlight (Works in Debug)
iOS BGProcessingTask + Background Upload Not Executing Reliably on TestFlight (Works in Debug) Description: We are facing an issue with BGTaskScheduler and BGProcessingTask when trying to perform a background audio-upload flow on iOS. The behavior is inconsistent between Debug builds and TestFlight (Release) builds. Summary of the Problem Our application records long audio files (up to 1 hour) and triggers a background upload using: BGTaskScheduler BGProcessingTaskRequest Background URLSession (background with identifier) URLSession background upload task + AppDelegate.handleEventsForBackgroundURLSession In Debug mode (Xcode → Run on device), everything works as expected: BGProcessingTask executes handleEventsForBackgroundURLSession fires Background URLSession continues uploads reliably Long audio files successfully upload even when the app is in background or terminated However, in TestFlight / Release mode, the system does not reliably launch the BGProcessingTask or Background URLSession events. Technical Details We explicitly register BGTaskScheduler: BGTaskScheduler.shared.register( forTaskWithIdentifier: "example.background.process", using: nil ) { task in self.handleBackgroundProcessing(task: task as! BGProcessingTask) } We schedule it using: let request = BGProcessingTaskRequest(identifier: "example.background.process") request.requiresNetworkConnectivity = true request.requiresExternalPower = false try BGTaskScheduler.shared.submit(request) We also use Background URLSession: let config = URLSessionConfiguration.background(withIdentifier: sessionId) config.sessionSendsLaunchEvents = true config.isDiscretionary = false AppDelegate.handleEventsForBackgroundURLSession is implemented correctly and works in Debug. Issue Observed (TestFlight Only) In TestFlight builds: BGProcessingTask rarely triggers, or the system marks it as NO LONGER RUNNING. Background upload tasks sometimes never start or complete. No logs appear from our BGProcessingTask handler. system logs show messages like: NO LONGER RUNNING bgProcessing-example.background.process Tasks running in group [com.apple.dasd.defaultNetwork] are 1! This occurs most frequently for large audio uploads (30–60 minutes), while small files behave normally. What We Have Verified Proper Info.plist values: Permitted background modes: processing, audio, fetch BGTaskSchedulerPermittedIdentifiers contains our identifier BGProcessingTask is being submitted successfully (no errors) App has microphone permission + background audio works Device plugged/unplugged doesn’t change outcome Key Question for Apple We need clarification on: Why BGProcessingTask behave differently between Debug and TestFlight builds? Are there additional restrictions or heuristics (related to file size, CPU usage, runtime, network load, or power constraints) that cause BGProcessingTask to be throttled or skipped in Release/TestFlight? How can we guarantee a background upload continues reliably for large files (100MB–500MB) on TestFlight and App Store builds? Is there an Apple-recommended pattern to combine BGProcessingTask + Background URLSession for long-running uploads? Expected Result Background uploads should continue reliably for long audio files (>30 minutes) when the app goes to background or is terminated, in the same way they currently function in Debug builds.

Notification Service Extension is killed during startup
We are observing an issue where the iOS Notification Service Extension (NSE) is terminated by the system during startup, before either didReceive(_:withContentHandler:) or serviceExtensionTimeWillExpire(_:) is invoked. When this occurs, the notification is delivered without modification (for example, an encrypted payload is shown to the user). System logs frequently contain the message “Extension will be killed because it used its runtime in starting up”. During testing, we observed that CPU-intensive operations or heavy initialization performed early in the extension lifecycle — especially inside init() or directly on the main thread in didReceive often cause the system to kill the NSE almost immediately. These terminations happen significantly earlier than the commonly observed ~30-second execution window where the OS normally invokes serviceExtensionTimeWillExpire(_:) before ending the extension. When these early terminations occur, there is no call to the expiry handler, and the process appears to be forcefully shut down. Moving the same operations to a background thread changes the behavior: the extension eventually expires around the usual 30-second window, after which the OS calls serviceExtensionTimeWillExpire(_:). We also observed that memory usage plays a role in early termination. During tests involving large memory allocations, the system consistently killed the extension once memory consumption exceeded a certain threshold (in our measurements, this occurred around 150–180 MB). Again, unlike normal time-based expiration, the system did not call the expiry handler and no crash report was produced. Since Apple’s documentation does not specify concrete CPU, memory, or startup-cost constraints for Notification Service Extensions or any other extensions beyond the general execution limit, we are seeking clarification and best-practice guidance on expected behaviors, particularly around initialization cost and the differences between startup termination. NSE Setup: class NotificationService: UNNotificationServiceExtension { static var notificationContentHandler: ((UNNotificationContent) -> Void)? static var notificationContent: UNMutableNotificationContent? static var shoudLoop = true override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) { NotificationService.notificationContentHandler = contentHandler NotificationService.notificationContent = request.content.mutableCopy() as? UNMutableNotificationContent NotificationService.notificationContent!.title = "Weekly meeting" NotificationService.notificationContent!.body = "Updated inside didReceive" // Failing scenarios } override func serviceExtensionTimeWillExpire() { NotificationService.shoudLoop = false guard let handler = NotificationService.notificationContentHandler, let content = NotificationService.notificationContent else { return } content.body = "Updated inside serviceExtensionTimeWillExpire()" handler(content) } }

UITableView section flickering with Liquid Glass design
Description of the current implementation: A section, UIView, has been added to UITableView. This section is a UICollectionView that displays an array of images. Each UICollectionViewCell is an image displayed via a UIImageView. Issue: When UITableView is scrolled vertically, the section with the image collection flickers. Attempts made to solve the problem: if #available(iOS 26.0, *) { tableView.bottomEdgeEffect.isHidden = true tableView.topEdgeEffect.isHidden = true tableView.leftEdgeEffect.isHidden = true tableView.rightEdgeEffect.isHidden = true } else { // Fallback on earlier versions } This helped with a similar issue. I tried it on UITableView and UICollectionView, but it didn't work.

TestFlight builds expired immediately after new build upload & subsequent new build submission failure
I am experiencing a critical issue with my TestFlight builds and the App Store Connect submission process. I need urgent assistance as all my testing builds are currently expired. To fix the expiration, I increased the build number to Build 5 (Version 1.0.3) and uploaded it. I then tried to Submit for Review. The submission process failed, and I received an error message Has anyone experienced a widespread issue like this recently? What steps can I take to troubleshoot the submission error, and why would all my builds expire simultaneously, just days after a new upload? Thank you for your help!

iOS Universal Link opens app and then opens browser (Flutter + Universal Links) — only when using paths/params
Hi everyone, I’ve been stuck on an issue with iOS Universal Links for about a week and could really use some help. The problem When tapping a Universal Link on iOS, my Flutter app opens correctly (desired behavior) — but immediately afterward, Safari opens the same link in the browser. So both the app and the browser open. This only happens on iOS. On Android everything works as expected. What works If the link is simply the domain, like: https://mydomain.com …then the app opens without triggering the browser afterward. This is the correct behavior. What doesn’t work If the link includes a path or parameters, like: https://mydomain.com/path https://mydomain.com/path?param=value …then the app opens, and then the browser opens immediately after. What I’ve tried Verified my AASA file using Branch’s validator: https://branch.io/resources/aasa-validator/ → The AASA file is valid. Universal Links do open the correct screen inside the app — the issue is the unwanted second step (Safari opening). Behavior is consistent across different iOS devices. Extra details Using Flutter. Universal Links set up with the standard configuration (associatedDomains, AASA hosted at /.well-known/apple-app-site-association, etc.). Question Has anyone encountered this issue where Universal Links with paths/params open the app and then open Safari? What could cause iOS to trigger the browser fallback even when the AASA file is valid and the app handles the link correctly? Any insights, debugging tips, or known edge cases would be incredibly appreciated!

Request: Implement beforeinstallprompt event for PWA installation prompts in Safari
I'm building a progressive web app (PWA) and came to the conclusion that almost nobody knows that this feature exists - Add to Home Screen. Not many people even understand what a PWA is or that you can add it to the home screen. This feels unnatural compared to installing an app from a store. Why do we make it so hard for users? Could we not make this easier by having the ability to call this installation or show an install notification? Right now, when users visit a PWA on iOS, there's no way for developers to let them know they can install it. The "Add to Home Screen" option is tucked away in the Share menu, and most users never find it. I'd really like to be able to show them a friendly prompt. Comparing to other browsers, this is possible via the beforeinstallprompt event. This would make a huge difference for user experience. Right now the only way is to show iOS users a separate set of instructions with screenshots, which feels clunky compared to what's possible on other platforms. I'm curious - is there any reason why this hasn't been added to Safari yet? Other browsers have supported this for years now. Is there any progress being made on this, or is it being considered for the roadmap? It would be really helpful to know if this is something that will be worked on in the future. I know there's a lot on the roadmap, but this would really help developers create better installation experiences for our users. Thanks for considering this!

TabView + NavigationStacks broken on iOS 26.1
Broken TabView + NavigationStacks functionality on iOS 26.1. Even the most basic navigation made impossible. Example: TabView { Tab(...) { NavigationStack(path: $homePath) { HomeView() .navigationDestination { ... } } } Tab(...) { NavigationStack(path: $settingsPath) { SettingsView() .navigationDestination { ... } } } } Anything passed to settingsPath is just ignored and would never appear onscreen. (26.0 and prior versions work as expected.) Are there any workarounds?

iOS Dark mode Liquid Glass Tab bar with Reduce Transparency Issue
Hi, I have an iOS app that I’m trying to update with Liquid Glass. In this app, I’m using a tab bar, which works fine with Liquid Glass, but as soon as I enable the “Reduce Transparency” setting in dark mode, I get a strange effect: at launch, the tab bar appears correctly in dark mode, but after scrolling a bit in the view, it eventually switches to light mode 😅 At launch: After a bit of scrolling: I can’t figure out whether this is intended behavior from the framework or not (I don’t have this issue with other apps). I can reproduce it in a project built from scratch, here is the code (don't forget to set dark mode to the device and activate the reduce transparency option in the accessibility menu): struct ContentView: View { var body: some View { TabView { ScrollView { LazyVStack { ForEach(0..<100) { _ in Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello world").foregroundStyle(.primary) } } .padding() } .tabItem { Label("Menu", systemImage: "list.dash") } } } } Do you know if this is expected behavior? Or if there’s something that can be done about it? Thanks,

builtInLiDARDepthCamera doesn't work on the 2020 iPad Pro on iOS 26
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?

Age verification: How to obtain the method of age assurance?
In the summary documentation about the declared Age Range API:https://developer.apple.com/news/?id=2ezb6jhj It states: "The API will also return a signal from the user’s device about the method of age assurance, such as credit card or government ID" But if the api itself, and its documentation is examined, there is no such mechanism nor mention of it: https://developer.apple.com/documentation/declaredagerange/agerangeservice So my question is, is the first documentation incorrect, if not, then where and how to access the method of age assurance?

Modal presentation of SwiftUI view with TextField leads to frozen UI, missing keyboard and memory leak
Hello, I’m trying to present my custom SwiftUI dialog with text field in UIKit with modalPresentationStyle = .overFullScreen, but it leads to the UI being completely frozen once I select the TextField and memory constantly leaking. The minimal reproducible code is: class ModalBugViewController: UIViewController { var hostingController: UIHostingController<Content>! struct Content: View { @State private var text = "" var body: some View { ZStack { Color.black.opacity(0.5).ignoresSafeArea() VStack { TextField("Test", text: $text) .textFieldStyle(.roundedBorder) .padding() } } } } override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .clear hostingController = UIHostingController(rootView: Content()) addChild(hostingController) view.addSubview(hostingController.view) hostingController.view.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ hostingController.view.topAnchor.constraint(equalTo: view.topAnchor), hostingController.view.bottomAnchor.constraint(equalTo: view.bottomAnchor), hostingController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor), hostingController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor) ]) hostingController.didMove(toParent: self) } } And then in UIKit source view: let viewController = ModalBugViewController() viewController.modalPresentationStyle = .overFullScreen present(viewController, animated: true) The bug is reproducible on iOS 18 - 26.1, even on the simulator, although on iOS 26 it's in landscape mode only. Is there some workaround for this issue that doesn't involve rewriting the whole dialog in UIKit?

VNDocumentCameraViewController UI issues in iOS 26
We're observing several UI issues with VNDocumentCameraViewController on devices running iOS 26. These screens were functioning correctly in earlier iOS versions. Issue 1 - On the edge correction screen, the top bar now appears as a gray strip beneath the status bar, whereas in previous iOS versions, it was positioned at the bottom of the screen. Do we have any workarounds to address this issue? Issue2 - The edit buttons and their labels are not clearly visible, affecting usability. Im using XCode 16.4 to build to iOS26 and the usage is like below: `let scanner = VNDocumentCameraViewController() scanner.delegate = self self.present(scanner, animated: true)`
