Overview

The same code built in a regular Mac app (with UI) does get paired. The characteristic properties are [.read, .write, .notify, .notifyEncryptionRequired] The characteristic permissions are [.readEncryptionRequired, .writeEncryptionRequired] My service is primary. In the iOS app (central) I try to read the characteristic, but an error is reported: Error code: 5, Description: Authentication is insufficient.

Updated version of this post My HomePod mini is now on version 16.4, so the the temperature and humidity sensors are enabled. The data properly shows up in the Home app on my various devices. In my HomeKit iPad app running on Mac Catalyst, however, the data does not show up. I would expect the HomePod mini to show up in HMHome.accessories with a service of type HMServiceTypeTempatureSensor. I see all of my other HomeKit accessories, just not the HomePod mini. I have tried with the latest Xcode (14.3) and highest available iOS Target and Minimum Deployment (16.4), macOS version 13.3. I have not, as of this writing, upgraded my HomeKit architecture, however. Note that I haven't tried the app on an actual iPad (and the iOS simulator doesn't expose my HomeKit environment.)

I'm on macOS Sequoia Version 15.7.3 (24G419) and using Xcode Version 26.2 (17C52). In my Xcode project, Transaction.updates and Product.SubscriptionInfo.Status.updates don’t seem to emit updates reliably. The code below works consistently in a fresh Xcode project using a minimal setup with a local StoreKit Configuration file containing a single auto-renewable subscription. class InAppPurchaseManager { static let shared = InAppPurchaseManager() var transactionTask: Task<Void, Never>? var subscriptionTask: Task<Void, Never>? init() { print("Launched InAppPurchaseManager...") transactionTask = Task(priority: .background) { for await result in Transaction.updates { print("\nReceived transaction update...") try? await result.payloadValue.finish() } } subscriptionTask = Task(priority: .background) { for await result in Product.SubscriptionInfo.Status.updates { print("\nReceived subscription update...") print("state:", result.state.localizedDescription) } } } } I initialise it in: func applicationDidFinishLaunching(_ aNotification: Notification) { _ = InAppPurchaseManager.shared } I do not build any UI for this test. I open StoreKit Transaction Manager then click Create Transaction → select the product → choose Purchase (Default) → Next → Done. The console shows that it detects the initial purchase, renewals and finishes each transaction. It also works even if I do not add the In-App Purchase capability. In my actual project, the initial purchase is detected and finished, but renewals are not detected. Subsequent transactions then appear as unverified, presumably because the updates are not being observed so the transactions are not being finished. What can I do to make this work reliably in my actual project? For context, in the actual project: I have a StoreKit Configuration file that is synced with App Store Connect The In-App Purchase capability is enabled The configuration file is selected in the scheme The products in App Store Connect show “Ready to Submit” Loading products works: try await Product.products(for: ...) Also, I use ProductView for the purchase UI. The first purchase works and is detected and finished, but subsequent renewals are not finished because the updates do not seem to be emitted.

I installed xcode 16 and both Predictive Code Completion Model and iOS 18.0 Simulator Failed Download. I can live without the code completion, but I can not get any Simulator to install.

NSWindow objects with custom styleMask configurations seem to behave erratically in macOS Tahoe 26.3 RC. For example an NSWindow is not resizable after issuing .styleMask.remove(.titled) or some NSWindow-s become totally unresponsive (the NSWindow becomes transparent to mouse events) with custom styleMask-s. This is a radical change compared to how all previous macOS versions or the 26.3 beta3 worked and seriously affects apps that might use custom NSWindows - this includes some system utilities, OSD/HUD apps etc, actually breaking some apps. Such fundamental compatibility altering changes should not be introduced in an RC stage (if this is intentional and not a bug) imho.

Since the beta releases of iPadOS 26 we have been having some crashes about Invalid parameter not satisfying: parentEnvironment != nil We got to contact a couple of users and we found out that the crash appears when entering a screen in a UINavigationController with the iPad device connected to a Magic Keyboard. If the device is not connected to the keyboard then nothing happens and everything works ok. From our end we haven't managed to reproduce the crash so I am pasting part of the stacktrace if it can be of any help. 3 UIKitCore 0x19dfd2e14 -[_UIFocusContainerGuideFallbackItemsContainer

I have tried the following code interface: IOBufferMemoryDescriptor： a. withCapacity(bufferSize, kIODirectionInOut, true)； b. inTaskWithPhysicalMask(kernel_task, kIODirectionInOut, bufferSize, 0x00000000FFFFFFFFULL)。 The physical addresses of the constructed descriptors are all >32 bits; IODMACommand： a. withSpecification(kIODMACommandOutputHost64, 64, 0, IODMACommand::kMapped, 0, 0)，gen64IOVMSegments() The allocated IOVM address must be>32 bits, which will generate a kernel panic when used later. b.withSpecification(kIODMACommandOutputHost32, 32, 0, IODMACommand::kMapped, 0, 0)，gen32IOVMSegments() The allocation of IOVM failed with error code kIOReturnenMessageTooLarge. So after the above attempts, the analysis shows that the strategy of Dart+PCIe root port on macOS (Apple Silicon) is causing the failure of 64 bit DMA address transfer. I have two questions: a. Does Dart in macOS (Apple Silicon) definitely not allocate <=32-bit IOVM addresses? b. Is there any other way to achieve DMA transfer for FGPA devices on macOS (Apple Silicon)? Thanks！

I've discovered an issue with using iOS 16's Transferable drag-and-drop APIs for SwiftUI. The dropDestination modifier does not work when applied to a subview of a List. This code below will not work, unless you replace the List with a VStack or any other container (which, of course, removes all list-specific rendering). The draggable modifier will still work and the item will drag, but the dropDestination view won't react to it and neither closure will be called. struct MyView: View { var body: some View { List { Section { Text("drag this title") .font(.largeTitle) .draggable("a title") } Section { Color.pink .frame(width: 400, height: 400) .dropDestination(for: String.self) { receivedTitles, location in true } isTargeted: { print($0) } } } } } Has anyone encountered this bug and perhaps found a workaround?

I'm struggling to understand whether TextField handles undo by itself, or how to properly handle it myself. In a macOS app with a SwiftUI lifecycle, in a DocumentGroup scene, I'm using both TextEditors and Textfields. The text editors handle undo out of the box, with undo coalescing. The text fields seem not to. However, on occasion, they do create undo points, leaving me confused as to what conditions are needed for that to happen. Is there a way to reliably get text fields to handle undo on their own? Or, how should I implement typing undo, including undo coalescing, manually?

Hello, We're developing endpoint security software using the Endpoint Security framework, and we've encountered challenges with the behavior change in macOS 15 regarding provisioning UDIDs in cloned VMs. The Change Prior to macOS 15, cloning a VM preserved its UDID (format: 0000FE00-9C4ED9F68BBDC72D). Starting with macOS 15, cloned VMs receive a new UDID generated from the host's Secure Enclave (format: b043d27202c7ac37ca3c6b82673302225485cae9), making each clone effectively a new device. Our Workflow We maintain a clean base VM image and clone it for each test run. We add the base VM's UDID to our provisioning profile once, then create clones which (previously) retained that same UDID, allowing us to start new testing cycles without re-registering devices. This is essential because our product involves low-level system integration through the Endpoint Security framework, and if something goes wrong during development, it has the potential to affect system stability. To prevent any cascading issues between test runs or different product versions, we need each test to start from a known clean state rather than reusing the same VM. The Challenge With each VM clone generating a new UDID, we're hitting Apple's device registration limits quickly. This particularly impacts: New team members who spin up VMs for the first time and can't run signed builds Our CI/CD pipeline where multiple test environments need provisioning profiles Developers testing different branches who need separate clean environments Current Workaround We've found that VMs created on macOS 14 and upgraded to macOS 15+ retain their original UDID format. However, we're concerned this workaround may stop working in future macOS versions, which would leave us without a viable path forward. If the workaround stops working, our fallback would be signing each CI build with a Developer ID signature to allow running on any device. However, we'd prefer to avoid this as it would significantly increase load on Apple's signing infrastructure for what are essentially internal test builds. We completely understand the security reasoning behind tying UDIDs to the host's Secure Enclave for Apple Account support. However, for development workflows that don't require Apple Account features in VMs but do require clean, isolated test environments, the previous behavior was quite valuable. Question Is there a recommended approach for teams in our situation? We're happy to explore alternative workflows if there's a pattern we're missing, or we'd be glad to provide more context if this is a use case Apple is considering for future updates. Thanks for any guidance you can provide! Feedback case: FB21389730

During Apple Pay in-app provisioning (EV_ECC_v2), our iOS app successfully obtains the issuer provisioning certificates and generates cryptographic material. The flow fails when Apple posts the card blob to Apple’s broker (card creation step), returning HTTP 500 from .../broker/v4/devices/{SEID}/cards. Steps: Call issuerProvisioningCertificates?encryptionVersion=EV_ECC_v2 → 200 OK; returns ECC leaf + Apple Root CA chain; nonce=2a831be4. 2.

I work on some proprietary codebases and can only use private AI services with them (currently MiniMax M2.1 and GLM 4.7). It all works great with both Claude Code and OpenCode agents, and I'd like to leverage the new agentic capabilities that are now in Xcode 26.3. I'm not seeing any option to connect to OpenCode, and both the Anthropic and OpenAI providers require an enterprise account (which I don't have access to). Are there any options that I'm missing here?

For testing permission response we can use the sandbox account However, when testing permission requests using the AskCenter API, none of the ask API works for me in xcode 26.2 rc and iOS 26.2 rc. For SignificantAppUpdateTopic, I got errors like "The user is in a region that does not support this type of ask" in the console log, but I've already set my billing address to Texas. For CommunicationTopic, the console shows several XPC-related errors, and I’m not sure which of them are relevant. Both of them show an alert view of "Can't ask, An unknown error occurred" Can someone help to guide us how to test the request flow? Thanks

QuickLookAR shares the actual USDZ model instead of the original website URL — critical copyright and data leak issue on iOS 26 Since iOS 26, QuickLookAR (or ARQuickLookPreviewItem) no longer preserves the original web URL when sharing a model. Instead of sending the link to the hosted file, the system directly shares the actual USDZ model file with the recipient. This is a critical regression and a severe breach of intellectual property protection, as it exposes proprietary 3D models that must never be distributed outside of the controlled web environment. In earlier iOS versions (tested up to iOS 18), QuickLookAR correctly handled sharing — the share sheet would send the website link where the model is hosted, not the file itself. Starting with iOS 26, this behavior has changed and completely breaks the intended secure flow for AR experiences. Our project relies on allowing users to view models in AR via QuickLook, without ever transferring the underlying 3D assets. Now, the share operation forces full file sharing, giving end users unrestricted access to the model file, which can be copied, rehosted, or reverse-engineered. This issue critically affects production environments and prevents us from deploying our AR-based solutions. Implement a standard QuickLookAR preview with a USDZ file hosted on your web server (e.g., via ARQuickLookPreviewItem). 2. Open the AR view on iOS 26. 3. Tap the Share icon from QuickLookAR. 4. Send via any messenger (Telegram, WhatsApp, etc.). 5. Observe that the actual .usdz model is sent instead of the original website URL. ⸻ Expected behavior: QuickLookAR should share only the original URL (as in iOS 17–18), not the file itself. This ensures that intellectual property and licensed 3D models remain protected and controlled by the content owner. ⸻ Actual behavior: QuickLookAR shares the entire USDZ file, leaking the model content outside of the intended environment. ⸻ Impact: • Violation of copyright and confidential data policies • Loss of control over proprietary 3D assets • Breaking change for all existing web-based AR integrations • Critical blocker for AR production deployment ⸻ Environment: • iOS 26.0 and 26.1 (tested on iPhone 14, iPhone 15) • Safari + QuickLookAR integration • Works correctly on iOS 17 / iOS 18 ⸻ Notes: This regression appears to have been introduced in the latest iOS 26 system handling of QuickLookAR sharing. Please escalate this issue to the ARKit / QuickLook engineering team as it directly affects compliance, IP protection, and usability of AR features across production applications. Additional Notes / Verification: Please test this behavior yourself using the CheckAR test model on my website: https://admixreality.com/ios26/ • If the login page appears, click “Check AR” and then “View in Your Space”. • On iOS 18 and earlier, sharing correctly sends the website URL. • On iOS 26, sharing sends the actual USDZ model file. This clearly demonstrates the regression and the security/IP issue.

Hi, I have been recently debugging the BGContinuedProcessingTask API and encountered some of the following issues. I hope you can provide some answers: First, let me explain my understanding of this API. I believe its purpose is to allow an app to trigger tasks that can be represented with progress indicators and require a certain amount of time to complete. After entering the background, these tasks can continue to be completed through the BGContinuedProcessingTask, preventing the system from terminating them before they are finished. In the launchHandler of the registration process, we only need to do a few things: Determine whether the actual business processing is still ongoing. Update the progress, title, and subtitle. Handle the expirationHandler. Set the task as completed. Here are some issues I encountered during my debugging process: After I called register and submit, the BGContinuedProcessingTask could not be triggered. The return values from my API calls were all normal. I tried different device models, and some could trigger the task normally, such as the 15 Pro Max and 12 Pro Max. However, there were also some models, such as the 17 Pro, 15 Pro, and 15, that could not trigger the task properly. Moreover, there was no additional error information to help locate the issue. The background task failed unexpectedly, but my app was still running normally. As I mentioned above, my launchHandler only retrieves the actual business status and updates it. If a background task fails unexpectedly while the app is still running normally, it can mislead users and degrade the user experience of the app. Others have also mentioned the issue of inconsistent behavior on devices that do not support Dynamic Island. On devices that support Dynamic Island, when a task is triggered in the foreground, the app does not immediately display a pop-up notification within the app. However, on devices that do not support Dynamic Island, the app directly displays a pop-up notification within the app, and this notification does not disappear when switching between different screens within the same app. The user needs to actively swipe up to dismiss it. I think this experience is too intrusive for users. I would like to know whether this will be maintained in the future or if there is a plan to fix it. On devices that do not support Dynamic Island, using the beta version 26.1 of the system, if the system is in dark mode but the app triggers a business interface in white, the pop-up notification will have the same color as the current page, making it difficult to read the content inside the pop-up. Users can actively stop background tasks by using the stop button, or the system can also stop tasks automatically when resources are insufficient or when a task is abnormal. However, according to the current API, all these actions are triggered through the expirationHandler. Currently, there is no way to distinguish whether the task was stopped by the user, by the system due to resource insufficiency, or due to an abnormal task. I would like to know whether there will be more information provided in the future to help distinguish these different scenarios. I believe that the user experience issues mentioned in points 2 and 3 are the most important. Please help to answer the questions and concerns above. Thank you!

This is my first driver and I have had the devil of a time trying to find any information to help me with this. I beg help with this, since I cannot find any tutorials that will get me over this problem. I am attempting to write a bridging driver for an older UPS that only communicates via RPC-over-USB rather than the HID Power Device class the OS requires. I have written the basic framework for the driver (details below) and am calling OSSystemExtensionRequest.submitRequest with a request object created by OSSystemExtensionRequest.activationRequest, but the didFailWithError callback is called with OSSystemExtensionErrorDomain of a value of 9, which appears to be a general failure to activate the driver. I can find no other information on how to address this issue, but I presume the issue is one of entitlements in either the entitlements file or Info.plist. I will have more code-based details below. For testing context, I am testing this on a 2021 iMac (M1) running Sequoia 15.7, and this iMac is on MDM, specifically Jamf. I have disabled SIP and set systemextensionsctl developer on, per the instructions here, and I have compiled and am attempting to debug the app using xcode 26.2. The driver itself targets DriverKit 25, as 26 does not appear to be available in xcode despite hints on google that it's out. For the software, I have a two-target structure in my xcode project, the main Manager app, which is a swift-ui app that both handles installation/activation of the driver and (if that finally manages to work) handles communication from the driver via its UserClient, and the driver which compiles as a dext. Both apps compile and use automated signing attached to our Apple Development team. I won't delve into the Manager app much, as it runs even though activation fails, except to include its entitlements file in case it proves relevant <dict> <key>com.apple.developer.driverkit.communicates-with-drivers</key> <true/> <key>com.apple.developer.system-extension.install</key> <true/> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.files.user-selected.read-only</key> <true/> </dict> and the relevant activation code: func request(_ request: OSSystemExtensionRequest, didFailWithError error: any Error) { // handling the error, which is always code value 9 } func activateDriver() { let request = OSSystemExtensionRequest.activationRequest(forExtensionWithIdentifier: "com.mycompany.driver.bundle.identifier", queue: .main) request.delegate = self OSSystemExtensionManager.shared.submitRequest(request) //... } And finally the Manager app has the following capabilities requested for its matching identifier in our Apple Developer Account: DriverKit Communicates with Drivers System Extension On the Driver side, I have two major pieces, the main driver class MyDriver, and UserClient class, StatusUserClient. MyDriver derives from IDriverKit/IOService.iig but (in case this is somehow important) does not have the same name as the project/target name MyBatteryDriver. StatusUserClient derives from DriverKit/IOUserClient.iig. I have os_log(OS_LOG_DEFAULT, "trace messages") code in every method of both classes, including the initializers and Start implementations, and the log entries never seem to show up in Console, so I presume that means the OS never tried to load the driver. Unless I'm looking in the wrong place? Because I don't think the driver code is the current issue, I won't go into it unless it becomes necessary. As I mentioned above, I think this is a code signing / entitlements issue, but I don't know how to resolve it. In our Apple Developer account, the Driver's matching identifier has the following capabilities requested: DriverKit (development) DriverKit Allow Any UserClient (development) DriverKit Family HID Device (development) -- NOTE: this is planned for future use, but not yet implemented by my driver code. Could that be part of the problem? DriverKit Transport HID (development) DriverKit USB Transport (development) DriverKit USB Transport - VendorID -- submitted, no response from Apple yet HID Virtual Device -- submitted, no response from Apple. yet. This is vestigial from an early plan to build the bridge via shared memory funneling to a virtual HID device. I think I've found a way to do it with one Service, but... not sure yet. Still, that's a problem for tomorrow. Apparently I've gone over the 7000 character maximum so I will add my entitlements and info.plist contents in a reply.

I hope you’re having a fantastic New Year and that your apps are doing great! This is my first time entering SSC , and I’m excited to share that I’m developing a screen timer app. The idea is to encourage you to take breaks by suggesting a run or workout instead of spending too much time on your screens. I was wondering, have anyone else included short videos or animations in their entries before? Also, could my screen time timer be running in the background? I know there are some limitations with integrations like HealthKit and Screen Time, which is why I’m using a regular countdown timer on the App Store as a prototype. I’m just trying to clarify the rules below to make sure that it’s all good to go : “If your submission includes any open source software, music, photos, artwork, or any other content that you do not have ownership rights in, you agree to (a) comply with all applicable licensing terms and copyright obligations and (b) provide an explanation of why it was used.” And regarding any tracking stuff in the disqualification section, whereas nothing in the app should include: “You track and/or insert analytics code in your App Store meant to identify or track judges’ activity while they review your App Store.” But my app will only have a simple timer in it.

I have the following view hierarchy in my app: [UINavigationController] -> [MainViewController] -> [MyTabBarController] -> [DashboardViewController] In my MainViewController I have a button that pushes the MyTabBarController onto the navigation controllers stack. In the tab bar controller I only have one tab in this example showing the DashboardViewController. That all works fine, and when I tap the back button on MyTabBarController, everything works fine and the MainViewController is shown again. The UI works exactly how I want it, but when I load up the 'Debug Memory Graph' view, I can see that my DashboardViewController is still in memory and it seems the UITab has a reference to it. The MyTabBarController is NOT in memory anymore. MyTabBarController is very simple: class MyTabBarController: UITabBarController { override func viewDidLoad() { super.viewDidLoad() self.mode = .tabSidebar var allTabs:[UITab] = [] let mainTab = UITab(title: "Dashboard", image: UIImage(systemName: "chart.pie"), identifier: "dashboard", viewControllerProvider: { _ in return UINavigationController(rootViewController: DashboardViewController()) }) allTabs.append(mainTab) setTabs(allTabs, animated: false) } } And the DashboardViewController is empty: class DashboardViewController: UIViewController { } The only reason I created as a seperate class in this example is so I can easily see if it's visible in the memory debug view. I have uploaded the simple sample app to GitHub: https://github.com/fwaddle/TabbarMemoryLeakCheck Anyone have any suggestions? Here is a screen grab of the memory debug view showing the UITab having a reference to the DashboardViewController even though MyTabBarController has been dealloc'd:

I’m currently developing an application using WKWebView. After updating to iOS 26.2 Developer Beta, the following Web API started returning false: isUserVerifyingPlatformAuthenticatorAvailable MDN: https://developer.mozilla.org/ja/docs/Web/API/PublicKeyCredential/isUserVerifyingPlatformAuthenticatorAvailable_static This issue did not occur on iOS 26.1 — it only happens on the beta version. Has anyone else encountered this problem or is aware of any related changes? OS: iOS 26.2 beta 3 (23C5044b)
