We are currently developing an enterprise iOS application and are in the process of implementing Data Leakage Protection (DLP) features. As part of this effort, we need to control the available actions and target applications presented within the UIActivityViewController. Specifically, we would like to programmatically filter or restrict certain activities and destination apps shown in the share sheet based on user-specific permissions. These permissions will be dynamically evaluated and updated at runtime. This type of functionality is supported by the Microsoft Intune SDK. However, our objective is to implement this behavior natively within our application without relying on any third-party libraries. Could you please advise on the recommended approach or available APIs to achieve this level of control over the UIActivityViewController?

We have found a large number of memory-related crashes in iOS18, and multiple issues have finally pointed to this crash line xzm_xzone_malloc_tiny_outlined. Do not know how to solve it now

Issue: Push notifications are not being received for some users. What could be the possible causes? Push notifications are being sent from our own server, and we are receiving success responses from APNS. Users have confirmed that notifications are enabled on their devices, and they report no network issues.

We've identified a regression in iOS 26.0 and 26.1 Beta 4 where AVSpeechSynthesisVoice(language:) no longer respects user-selected voices from Accessibility settings. Issue: When users select a specific voice in Settings → Accessibility → Spoken Content → Voices, calling AVSpeechSynthesisVoice(language:) returns the system default voice instead of the user's selection. This worked correctly in iOS 18.6.2. Particularly affects: Third-party speech synthesis voices (CereProc, Grammatek, etc.) Apps relying on automatic voice selection based on user preferences Example: // User selected CereProc Heather for en-GB in Accessibility settings let voice = AVSpeechSynthesisVoice(language: "en-GB") print(voice?.name) // iOS 18.6.2: "HEATHER", iOS 26: "Daniel" (system default) Interesting observation: The new Accessibility Reader feature in iOS 26 correctly uses the user-selected voice, but Tap to Speak and the API both ignore the setting. Tested methods: AVSpeechSynthesisVoice(language:) AVSpeechUtterance auto-selection Reflection for new APIs All return the system default voice, not the user's preference. Filed: FB[20271264] Has anyone else encountered this? Any known workarounds to programmatically access the user's preferred voice selection?

Hi, we are developing a screen time management app. The app locks the device after it was used for specified amount of time. After updating to iOS 26.2, we noticed a huge issue: the events started to fire (reach the threshold) in the DeviceActivityMonitorExtension prematurely, almost immediately after scheduling. The only solution we've found is to delete the app and reboot the device, but the effect is not lasting long and this does not always help. Before updating to iOS 26, events also used to sometimes fire prematurely, but rescheduling the event often helped. Now the rescheduling happens almost every second and the events keep reaching the threshold prematurely. Can you suggest any workarounds for this issue?

Our app supports UIScene. As a result, launchOptions in application(_:didFinishLaunchingWithOptions:) is always nil. However, the documentation mentions that UIApplication.LaunchOptionsKey.location should be present when the app is launched due to a location event. Given that our app is scene-based: How can we reliably determine whether the app was launched due to a location update, geofence, or significant location change? Is there a recommended pattern or API to detect this scenario in a Scene-based app lifecycle? This information is critical for us to correctly initialize location-related logic on launch. Relevant documentation: https://developer.apple.com/documentation/corelocation/cllocationmanager/startmonitoringsignificantlocationchanges()

I want to be able to disable all liquid glass effects from my Navigation bar, and it's bar buttons. But I still want to be able to have the liquid glass effect on my UITabbar. Is there a way to disable glass effects from navbar and still retain them all for tabbars using UIKit?

I have a transformation function that takes in data, executes some instructions, and returns an output. This function is dynamic and not shipped with the binary. Currently, I’m executing it using JavaScriptCore.JSContext, which works well, but the function itself is written in JavaScript. Is there a way to achieve something similar using Swift – such as executing a dynamic Swift script, either directly or through other means? I know this is possible on macOS, but I’m not sure about iOS. I’ve also heard that extensions might open up some possibilities here. Any insights or alternative approaches would be appreciated.

Hello, I have an app in AppStore "Counter Widget". https://apps.apple.com/app/id1522170621 It allows you to add a widget to your homescreen/lockscreen to count anything. Everything works fine except for one scenario. iOS 18+ I create 2 or more widgets for one counter. For example, medium and small widgets. I click on the widget button to increase or decrease the value. The button in the widget uses Button(intent: AppIntent) to update the value and calls WidgetCenter.shared.reloadAllTimelines() to update the second widget for the same counter. For iOS 18 in this particular scenario, you don't even have to call the WidgetCenter.shared.reloadAllTimelines(). iOS already knows that there is a widget with the same INIntent settings and will update it itself. Both widgets are updated and show the new value. Everything is correct. Now on the homescreen I open the widget configuration for one of the widgets to change the INIntent for the widget. For example, i change the background to wallpaper. This is just a skin for the widget, and the widget is associated with the same counter value as before. As in (2), I click the widget button to increase or decrease the value. But now only one widget is updated. iOS ignores my call to WidgetCenter.shared.reloadAllTimelines() and does not update the second widget connected to the same counter. As I found, iOS, when I call WidgetCenter.shared.reloadAllTimelines() from the widget itself, updates other widgets only if INIntent is absolutely equal for them. Overriding isEqual for them did not help. That is, I cannot specify which fields from my INIntent can be ignored during such an update and consider that widgets are equal and need to be updated. Obviously iOS make this compare outside my code. The main problem is that when the user adds a widget to the lock screen and increases and decreases the value there. After that, he opens the home screen and the widget there is not synchronized with the value from the widget on the lock screen. How to solve this problem?

I have a couple of (older) UIKit-based Apps using UISplitViewController on the iPad to have a two-column layout. I'm trying to edit the App so it will shows the left column as sidebar with liquid glass effect, similar to the one in the "Settings" App of iPadOS 26. But this seems to be almost impossible to do right now. "out of the box" the UISplitViewController already shows the left column somehow like a sidebar, with some margins to the sides, but missing the glass effect and with very little contrast to the background. If the left column contains a UITableViewController, I can try to get the glass effect this way within the UITableViewController: tableView.backgroundColor = .clear tableView.backgroundView = UIVisualEffectView(effect: UIGlassContainerEffect()) It is necessary to set the backgroundColor of the table view to the clear color because otherwise the default background color would completely cover the glass effect and so it's no longer visible. It is also necessary to set the background of all UITableViewCells to clear. If the window is in the foreground, this will now look very similar to the sidebar of the Settings App. However if the window is in the back, the sidebar is now much darker than the one of the Settings App. Not that nice looking, but for now acceptable. However whenever I navigate to another view controller in the side bar, all the clear backgrounds destroy the great look, because the transition to the new child controller overlaps with the old parent controller and you see both at the same time (because of the clear backgrounds). What is the best way to solve these issues and get a sidebar looking like the one of the Settings App under all conditions?

If I use the method callAsyncJavaScript() my app will compile, but it won't run on older simulators. Specifically, in a brand new Storyboard project, I added this to `viewDidLoad(): let webView = WKWebView() webView.callAsyncJavaScript("1", in: nil, in: .page) { result in print("\(result)") } This runs fine with Xcode 16.3 targeting the iOS 18.4 simulator. It doesn't work if I target the iOS 18.3.1 simulator or the iOS 17.5 simulator. It does work on an iPhone 15 Pro running iOS 18.4 and it works on an iPhone 12 Pro running iOS 17.7.1. It goes without saying that this used to work on Xcode 16.2 and earlier, since my real project has been using that API for 3 or 4 years now.

Description: We are developing an iOS app that offers only one auto-renewable subscription. Recently, a user who had not subscribed for over a year purchased the subscription again through our app. However, when they checked Settings > Subscriptions, the new subscription did not appear. Instead, only their past subscription history was visible, and there was no option to cancel the new subscription. We have verified this issue with a screenshot provided by the user. Additionally, we checked our app’s logs and confirmed that StoreKit.product.purchase successfully returned .success, indicating that the purchase was processed correctly. Code used for purchase: let result = try await product? .purchase(options: [ .appAccountToken(uuid) ]) switch result { case .success(let verificationResult): switch verificationResult { case .verified(let transaction): addPurchaseLog("verificationResult.verified.") case .unverified(_, let verificationError): addPurchaseLog("verificationResult.unverified.") case .userCancelled, .pending, .none: addPurchaseLog("verificationResult.userCancelled or .pending or .none") @unknown default: addPurchaseLog("verificationResult.unknown.") } Despite the successful purchase, the new subscription does not appear under the user's active subscriptions. Could this be a bug in StoreKit? If there are any known issues or workarounds, we would appreciate any guidance. Environment: Xcode: 16.2 iOS version: 16.0+

I'm a web developer of WebRTC based web app for video and audio calls. After updating to iOS 26.1 beta I noticed, that my app can't use microphone anymore. When I'm calling to getUserMedia with audio set to true, Safari returns error "No AVAudioSessionCaptureDevice device". Other WebRTC demo apps also can't access microphone on this firmware. And maybe it's connected somehow, but safari can't detect connected AirPods Pro 2 as an input device. So, this bug brakes any WebRTC app, that uses microphones.

Hi all, I’ve got a usability question about accessibility navigation. My app has a lot of carousels (horizontally scrolling lists of content with far more elements than can fit on the screen). Often, these are just images, but sometimes, they’re cards with multiple subelements. In our previous implementation, each card was a single accessibility element, and we exposed the subelements as accessibility custom actions. Despite this, users frequently mentioned navigating with VoiceOver as a pain point. It takes a long time to navigate through and navigate past these carousels. To solve this, I converted my carousels into a single adjustable element, so users can navigate through it with one swipe, and they can still access the elements by adjusting the values up and down. I got this advice from this 2018 WWDC talk. Is this still the recommended advice? Or is there a new, preferred way to do this? Additionally, I had to get a little creative with the second carousel, the one with multiple subelements. Some of these were interactive (imagine a card with a description, an upvote button, and a downvote button). Adjustable elements override the accessibility custom actions VoiceOver gesture, so I can’t expose the individual buttons as actions. Instead, I made each subelement in each card in the carousel one of the adjustable values. Swiping up would go from description 1 to upvote button 1 to downvote button 1 to description 2, etc. Double tapping with VoiceOver would perform whatever action the carousel is currently on. So if I adjust the value to the element at index 2 (say, downvote 1), double tapping would trigger the downvote button’s action. Does this make sense? Is there a better way to do this? This seemed to be the best compromise between screenreader navigation speed, exposing all actions, and the existing UI.

Description I am seeing a consistent crash in a NEDNSProxyProvider on iOS when migrating from completion handlers to the new Swift Concurrency async/await variants of readDatagrams() and writeDatagrams() on NEAppProxyUDPFlow. The crash occurs inside the Swift Concurrency runtime during task resumption. Specifically, it seems the Task attempts to return to the flow’s internal serial executor (NEFlow queue) after a suspension point, but fails if the flow was invalidated or deallocated by the kernel while the task was suspended. Error Signature Thread 4: EXC_BAD_ACCESS (code=1, address=0x28) Thread 4 Queue : NEFlow queue (serial) #0 0x000000018fe919cc in swift::AsyncTask::flagAsAndEnqueueOnExecutor () #9 0x00000001ee25c3b8 in _pthread_wqthread () Steps The crash is highly timing-dependent. To reproduce it reliably: Use an iOS device with Developer Settings enabled. Go to Developer > Network Link Conditioner -> High Latency DNS. Intercept a DNS query and perform a DoH (DNS-over-HTTPS) request using URLSession. The first few network requests should trigger the crash Minimum Working Example (MWE) class DNSProxyProvider: NEDNSProxyProvider { override func handleNewFlow(_ flow: NEAppProxyFlow) -> Bool { guard let udpFlow = flow as? NEAppProxyUDPFlow else { return false } Task(priority: .userInitiated) { await handleUDPFlow(udpFlow) } return true } func handleUDPFlow(_ flow: NEAppProxyUDPFlow) async { do { try await flow.open(withLocalFlowEndpoint: nil) while !Task.isCancelled { // Suspension point 1: Waiting for datagrams let (flowData, error) = await flow.readDatagrams() if let error { throw error } guard let flowData, !flowData.isEmpty else { return } var responses: [(Data, Network.NWEndpoint)] = [] for (data, endpoint) in flowData { // Suspension point 2: External DoH resolution let response = try await resolveViaDoH(data) responses.append((response, endpoint)) } // Suspension point 3: Writing back to the flow // Extension will crash here on task resumption try await flow.writeDatagrams(responses) } } catch { flow.closeReadWithError(error) flow.closeWriteWithError(error) } } private func handleFlowData(_ packet: Data, endpoint: Network.NWEndpoint, using parameters: NWParameters) async throws -> Data { let url = URL(string: "https://dns.google/dns-query")! var request = URLRequest(url: url) request.httpMethod = "POST" request.httpBody = packet request.setValue("application/dns-message", forHTTPHeaderField: "Content-Type") let (data, _) = try await URLSession.shared.data(for: request) return data } } Crash Details & Analysis The disassembly at the crash point indicates a null dereference of an internal executor pointer (Voucher context): ldr x20, [TPIDRRO_EL0 + 0x340] ldr x0, [x20, #0x28] // x20 is NULL/0x0 here, resulting in address 0x28 It appears that NEAppProxyUDPFlow’s async methods bind the Task to a specific internal executor. When the kernel reclaims the flow memory, the pointer in x20 becomes invalid. Because the Swift runtime is unaware that the NEFlow queue executor has vanished, it attempts to resume on non-existing flow and then crashes. Checking !Task.isCancelled does not prevent this, as the crash happens during the transition into the task body before the cancellation check can even run. Questions Is this a known issue of the NetworkExtension async bridge? Why does Task.isCancelled not reflect the deallocation of the underlying NEAppProxyFlow? Is the only safe workaround? Please feel free to correct me if I misunderstood anything here. I'll be happy to hear any insights or suggestions :) Thank you!

Hi Apple engineers! We are making an iOS browser and are planing to deliver a feature that allows enterprise customers to use a MAM key to set a PAC file for proxy. It's designed to support unmanaged device so the MDM based solutions like 'Global HTTP Proxy MDM payload' or 'Per-App VPN' simply don't work. After doing some research we found that with WKWebView, the only framework allowed on iOS for web browsing, there's no API for programmatically setting proxy. The closes API is the WKURLSchemeHandler, but it's for data management not network request interception, in other word it can not be used to handle HTTP/HTTPS request well. When we go from the web-view level to the app level, it seems there's no API to let an app set proxy for itself at an app-level, the closest API is Per-App VPN but as mentioned above, Per-App VPN is only available for managed device so we can't use that as well. Eventually we go to the system level, and try to use Network Extension, but there's still obstacles. It seems Network Extension doesn't directly provide a way to write system proxy. In order to archive that, we may have to use Packet Tunnel Provider in destination IP mode and create a local VPN server to loop back the network traffic and do the proxy stuff in that server. In other word, the custom VPN protocol is 'forward directly without encryption'. This approach looks viable as we see some of the network analysis tools use this approach, but still I'd like to ask is this against App Store Review Guidelines? If the above approach with Network Extension is not against App Store Review Guidelines, I have a further question that, what is the NEProxySettings of NETunnelNetworkSettings for? Is it the proxy which proxies the VPN traffic (in order to hide source IP from VPN provider) or it is the proxy to use after network traffic goes into the virtual private network? If none of the above is considered recommended, what is the recommended way to programmatically set proxy on WKWebView on an unmanaged device (regardless of where the proxy runs, web-view/app/system)?

I've got an iOS app with lots of extensions, some of them complex and doing a lot of stuff. After a bug I'd like to be able to use OSLogStore to get a holistic picture of logging for the app and its extensions and send that to a debugging server to retrospectively view logs for the app and its extensions. The constructor is OSLogStore.init(scope: OSLogStore.Scope), however scope only has one value .currentProcessIdentifier. Implying if that is called from within the app it can only get access to logging for its process only. I tried it out to confirm this is the case - if I log something in an extension (using Logger), then run the app with code like this:  let logStore = try! OSLogStore(scope: .currentProcessIdentifier)  let oneHourAgo = logStore.position(date: Date().addingTimeInterval(-3600)) let allEntries = try! logStore.getEntries(at: oneHourAgo)       for entry in allEntries { look at the content of the entry Then none of the entries are from the extension. Is there anyway from within the app I can access logging made within an extension?
