Overview

I've followed the setup process to get Apple Hosted Background Assets configured for my project. (https://developer.apple.com/documentation/backgroundassets/downloading-apple-hosted-asset-packs) But when I build and run the app I get the following error... BackgroundAssets/AssetPackManager.swift:174: Fatal error: The process lacks a team ID. I've checked the Signing->Team for both targets and they both have my Team associated. Any help or advice would be appreciated...

Hi, run into this error today: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.QJh2l0/extracted/MyAwesome.app : 0xe8008015 (A valid provisioning profile for this executable was not found.) Project is an AUv3 app + extension. It builds and install fine on MacOS. It builds on iPad but can't install : that's when the error appears. Regarding provisioning files, I use Automatic manage signing and I can see that the Xcode Managed Profile looks fine an includes my iPad. The only thing I see that differ from other projects is that as an AUv3 project, I have both and App (host) and extension projects. Thus the bundle identifier for this extension project is not the same as it seems I have to use different identifiers. So app bundle id is x.y while extension is x.y.z (same x.y base)) Last but not least the project and IPA can be built fine on XCode Cloud. (Although I can't download the artifacts but it seems it's the same problem for many of us today...) macOS Version 15.4 (Build 24E248) Xcode 16.2 (23507) (Build 16C5032a) Thanks in advance for your help :)

Hello, I think it is quite a common use-case to open the parent app that owns the ShieldActionDelegate when the user selects an action in the Shield. There are only three options available that we can do in response to an action: ShieldActionResponse.none ShieldActionResponse.close ShieldActionResponse.defer It would be great if this new one would be added as well: ShieldActionResponse.openParentApp While finding a workaround for now, the problem is that the ShieldActionDelegate is not a normal app extension. That means, normal tricks do not work to open the parent app from here. For example, UIApplication.shared.open(url) does not work because we can’t access UIApplication from the ShieldActionDelegate unfortunately. NSExtensionContext is also not available in the ShieldActionDelegate unfortunately, so that’s also not possible. There are apps however, that managed to find a workaround, in my research I stumbled across these two: https://apps.apple.com/de/app/applocker-passcode-lock-apps/id1132845904?l=en-GB https://apps.apple.com/us/app/app-lock/id6448239603 Please find a screen recording (gif) attached. Their workaround is 100% what I’m looking for, so there MUST be a way to do so that is compliant with the App Store guidelines (after all, the apps are available on the App Store!). I had documented my feature request more than 2 years ago in this radar as well: FB10393561

I am using macOS Tahoe on Xcode 26.

I honestly thought I was getting somewhere with this, but alas, no. Every time I do anything in my List of ItemRows it jumps back to the top. Here's the setup: DataService.swift: final class DataService { static let shared = DataService() private init() {} let coreData: CoreData = CoreData() let modelData: ModelData = ModelData() } ModelData.swift: @Observable class ModelData: ObservableObject { var allItems: [ItemDetails] var standardItems: [ItemDetails] var archivedItems: [ItemDetails] init() { allItems = [] standardItems = [] archivedItems = [] } func getInitialData() { // Get all items, then split them into archived and non-archived sets, because you can't use `.filter` in a view... allItems = dataService.coreData.getAllItems() standardItems.append(contentsOf: allItems.filter { !$0.archived }) archivedItems.append(contentsOf: allItems.filter { $0.archived }) } } MainApp.swift: // Get access to the data; this singleton is a global as non-view-based functions, including the `Scene`, need to access the model data let dataService: DataService = DataService.shared @main struct MainApp: App { // Should this be @ObservedObject or @StateObject? @ObservedObject private var modelData: ModelData = dataService.modelData // I would use @StateObject if the line was... //@StateObject private var modelData: ModelData = ModelData() // right? // But then I couldn't use modelData outside of the view hierarchy var body: some Scene { WindowGroup { ZStack { MainView() .environment(modelData) } } .onAppear { modelData.getInitialData() } } } MainView.swift: struct MainView: View { @Environment(ModelData.self) private var modelData: ModelData var body: some View { ... ForEach(modelData.standardItems) { item in ItemRow(item) } ForEach(modelData.archivedItems) { item in ItemRow(item) } } } ItemRow.swift: struct ItemRow: View { @Environment(\.accessibilityDifferentiateWithoutColor) private var accessibilityDifferentiateWithoutColor var item: ItemDetails @State private var showDeleteConfirmation: Bool = false var body: some View { // Construct the row view // `accessibilityDifferentiateWithoutColor` is used within the row to change colours if DWC is enabled, e.g. use different symbols instead of different colours for button images. // Add the .leftSwipeButtons, .rightSwipeButtons, and .contextMenu // Add the .confirmationDialog for when I want to ask for confirmation before deleting an item } } Now, the problems: Swipe an item row, tap one of the buttons, e.g. edit, and the list refreshes and jumps back to the top. In the console I see: ItemRow: @self, @identity, _accessibilityDifferentiateWithoutColor changed. Why did accessibilityDifferentiateWithoutColor change? The setting in Settings > Accessibility > Display & Text Size has not been changed, so why does the row's view think it changed? With a .confirmationDialog attached to the end of the ItemRow (as seen in the code above), if I swipe and tap the delete button the list refreshes and jumps back to the top again. In the console I see: ItemRow: @self, @identity, _accessibilityDifferentiateWithoutColor, _showDeleteConfirmation changed. Right, it changed for the one row that I tapped the button for. Why does every row get redrawn? I already had to shift from using the colorScheme environment variable to add new asset colours with light and dark variants to cover this, but you can't do that with DWC. Honestly, managing state in SwiftUI is a nightmare. I had zero problems until iOS 26 started removing one or two rows when I scrolled, and the fix for that - using @Statebject/@ObservedObject - has introduced multiple further annoying, mind-bending problems, and necessitated massive daily refactorings. And, of course, plenty of my time islost trying to figure out where a problem is in the code because "The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions"...

we already got access to com.apple.developer.usernotifications.filtering , we have set up this special permission in our app extension entitlement and provision profile. but we are still unable to filter notification by providing empty UNNotificationContent

I am adding In-App provisioning to my app. I am able to access the Apple Pay Sandbox and I have successfully tested adding a secure element/payment pass to Apple Wallet. However, once the pass has been added to the wallet, I can not access or retrieve the pass from my app. I have confirmed with the PNO that the PNO Pass Metadata Configuration in the testing environment include the correct metadata for "associatedApplicationIdentifiers" and "associatedStoreIdentifiers". Does anyone know why I am having this issue and how I can resolve it? Steps used to access pass in Apple Wallet I am unable to view the pass when I attempt to access it using the PKPassLibrary function as follows: let library = PKPassLibrary() if #available(iOS 13.4, *) { // This returns an empty array library.passes(of: .secureElement) } else { // This also returns an empty array library.passes(of: .payment) } // This returns an empty array too library.passes() Steps used to add pass to Apple Wallet These are the steps I follow to add the card: I create a PKAddPaymentPassRequestConfiguration I use this config to instantiate a PKAddPaymentPassViewController. I provide the nonce, nonceSignature, and certificates to my PNO along with the card data. I receive the activationData, encryptedPassData, and ephemeralPublicKey from my PNO and create a PKAddPaymentPassRequest using this data. I add the pass to Apple Wallet. In the addPaymentPassViewController callback, I am able to view the pass data from the .didFinishAdding pass: PKPaymentPass? variable. I am also able to see that the pass has been added from Apple Wallet app. I am not able to access the pass using PKPassLibrary().passes() at this point. I am not able to access the pass at any point after adding it either.

Since Xcode 26 our tests are crashing due to the Main Thread not being able to deallocate WKNavigationResponse. Following an example: import Foundation import WebKit final class WKNavigationResponeMock: WKNavigationResponse { private let urlResponse: URLResponse override var response: URLResponse { urlResponse } init(urlResponse: URLResponse) { self.urlResponse = urlResponse super.init() } convenience init(httpUrlResponse: HTTPURLResponse) { self.init(urlResponse: httpUrlResponse) } convenience init?(url: URL, statusCode: Int) { guard let httpURLResponse = HTTPURLResponse(url: url, statusCode: statusCode, httpVersion: nil, headerFields: nil) else { return nil } self.init(httpUrlResponse: httpURLResponse) } } import WebKit import XCTest final class ExampleTests: XCTestCase { @MainActor func testAllocAndDeallocWKNavigationResponse() { let expectedURL = URL(string: "https://galaxus.ch/")! let expectedStatusCode = 404 let instance = WKNavigationResponeMock() // here it should dealloc/deinit `instance` automatically } Here the call stack: Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 CoreFoundation 0x101f3dd54 CFRetain.cold.1 + 16 1 CoreFoundation 0x101e14860 CFRetain + 104 2 WebKit 0x10864dd24 -[WKNavigationResponse dealloc] + 52

First time working with DEXT, so I'm trying to make "Communicating between a DriverKit extension and a client app" sample project to work and I'm having trouble. I'm following the steps for "Automatically manage signing". It seems that the step “Sign to Run Locally” is wrong now, so I let it to Apple Developer. Now I have a Provisioning Profile error that says it doesn't include the com.apple.developer.driverkit.allow-any-userclient-access entitlement. If I go to Certificates, Identifiers and Profiles for this AppID and go to Capability Requests and select DriverKit Allow Any UserClient Access, this bring me to a page where I select DriverKit Entitlement but Any UserClient Access is not a choice. I tried asking for UserClient Access but the request has been denied saying that the engineering team does not think these entitlements are necessary for testing locally. So I removed com.apple.developer.driverkit.allow-any-userclient-access from NullDriver.entitlements. I can now install the DEXT but when I try "Communicate with Dext" button, I received the error: Failed opening connection to dext with error: 0xe00002e2. Looking in the console, I see this error message: DK: NullDriverUserClient-0x10000ad6a:UC failed userclient-access check, needed bundle ID com.example.apple-samplecode.dext-to-user-client-2-TEST.driver I tried many things, but I can't seem to be able to pass through the check to allow the application to communicate with the dext. What am I missing? Note that I'm focusing only on macOS, not iOS. Thanks.

Hello. My developer membership is expired. I cannot renew because the renewal option/button does not appears in any device. A banner tells me: "Any apps you had on the App Store are no longer available for download and you can no longer access membership benefits. If you’d like to renew your membership to reinstate your apps and membership benefits, open the Apple Developer app on your iPhone, iPad, or Mac. Sign in to your account, tap/click Renew, and follow the prompts.If you agreed to the Paid Applications Agreement, you’ll need to agree to it again after renewal in the Agreements, Tax and Banking section of App Store Connect." However, there's no "Renew" to tap or click anywhere in the app nor in the web. Any ideas? Thanks a lot.

Question based on the https://developer.apple.com/forums/thread/649172 What is the mechanics of using this entitlement? What should be done in the UNNotificationServiceExtension in order to prevent the display of a notification for the user? Just pass an empty UNNotificationContent object to contentHandler or something else?

I implemented BGContinuedProcessingTask in my app and it seems to be working well for everyone except one user (so far) who has reached out to report nothing happens when they tap the Start Processing button. They have an iPhone 12 Pro Max running iOS 26.1. Restarting iPhone does not fix it. When they turn off the background processing feature in the app, it works. In that case my code directly calls the function to start processing instead of waiting for it to be invoked in the register block (or submit catch block). Is this a bug that's possible to occur, maybe device specific? Or have I done something wrong in the implementation? func startProcessingTapped(_ sender: UIButton) { if isBackgroundProcessingEnabled { startBackgroundContinuedProcessing() } else { startProcessing(backgroundTask: nil) } } func startBackgroundContinuedProcessing() { BGTaskScheduler.shared.register(forTaskWithIdentifier: taskIdentifier, using: .main) { @Sendable [weak self] task in guard self != nil else { return } startProcessing(backgroundTask: task as? BGContinuedProcessingTask) } let request = BGContinuedProcessingTaskRequest(identifier: taskIdentifier, title: title, subtitle: subtitle) request.strategy = .fail if BGTaskScheduler.supportedResources.contains(.gpu) { request.requiredResources = .gpu } do { try BGTaskScheduler.shared.submit(request) } catch { startProcessing(backgroundTask: nil) } } func startProcessing(backgroundTask: BGContinuedProcessingTask?) { // FIXME: Never called for this user when isBackgroundProcessingEnabled is true }

"the compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions" ...... it killing me !!!!

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!

Hello, I created an app using the latest version of Xcode (16.2), and I'm having a problem testing this app on my iPhones. I created this app just like all the others I've made for my clients, including one on (03/24/25), but when I went to upload another App to App Store Connect on (03/26/25) I couldn't test it on my phone. Points to consider: The app runs perfectly on the Emulator. All my terms and agreements with Apple are up to date. I tried to download the apps through Testflight on 2 different devices, iPhone 7 Plus (iOS 15.8.1) and iPhone 15 Pro Max (iOS 18.3.2), and I was unsuccessful in neither attempt. I can send my app to the internal testers, but when I click download, the following message appears: Could not install [APP NAME]. The requested App is not available or doesn't exist. I imagine this problem is with Apple itself, I have already contacted support, but I need to resolve this urgently for my customers. Has anyone experienced this and resolved it?

Seemingly innocuous contents passed to tabViewBottomAccessory can trigger inscrutable AttributeGraph cycles, which can then cause unexplained broken behavior of views that may be participating in these cycles. These cycles can be introduced by adding common elements to the tabViewBottomAccessory view hierarchy, like Slider, Button, Toggle, and even things simple if statements surrounding Text elements. These cycles can even also be triggered in a manner that causes the tabViewBottomAccessoryPlacement Environment value to be nil, which can then cause views that depend on this value to render incorrectly or not at all. The errors logged to the Xcode console are of the form: === AttributeGraph: cycle detected through attribute 29528 === === AttributeGraph: cycle detected through attribute 324264 === No further information about this attribute is available in any public Xcode tools. Environment XCode Version 26.0 (17A324) iOS 26.0 (23A343) Steps to reproduce Run the sample above in Simulator Observe no AttributeGraph cycles in Xcode console. Uncomment any of the commented out examples in SliderView.body Observe Xcode console for AttributeGraph cycle messages. Observe glitchy animation behavior Expected Behavior No AttributeGraph cycle diagnostics for ordinary state changes. tabViewBottomAccessoryPlacement always present (non-nil) while accessory is attached. Dependent views update consistently. Errors logged to the Console would help guide me towards a resolution Impact Undermines confidence in adopting tabViewBottomAccessory. Hard to debug: cycle traces are opaque and environment silently degrades (becomes nil) instead of asserting. Nearly shipped a UI where accessory layout fails sporadically. What would help Underlying fix to prevent cycles for ordinary accessory content mutations. Guarantee (or documented contract) that tabViewBottomAccessoryPlacement is never nil while accessory is active, or an assert if invariants break. Option to enable detailed environment propagation trace when a cycle is detected. Symbolic source identifiers in cycle backtraces. Documentation note on current limitations (if certain view types are not yet supported in accessory regions).

I have an odd issue I'm trying to troubleshoot. I have an app that is deployed to our enterprise and works on almost all of our devices. Lately, I have devices (very small number) where the app installs from our MDM and it crashes upon launch, it does not get past the launch screen. If I remove and reinstall the app from the MDM it still crashes. I decided to put the devices in developer mode and if I run the App from Xcode on the device it works fine. If I stop it and run it right from the device it also works. If I do a final build of the app and install it using "Devices and Simulators", the app crashes upon launch. Using "Devices and Simulators" I check for crash log for the app and no file. I am stumped as to whats going on.

As of now, there is no Kernel Debug Kit (KDK) available for macOS 26.0 Developer Betas after the first build. Kernel Debug Kits are crucial for understanding panics and other bugs within custom Kernel Extensions. Without the KDK for the corresponding macOS version, tools like kmutil fail to recognize a KDK and certain functions are disabled. Additionally, as far as I am aware, a KDK for one build of macOS isn't able to be used on a differing build. Especially since this is a developer beta, where developers are updating their software to function with the latest versions of macOS, I'd expect a KDK to be available for more than one build.

I have SwiftData models containing arrays of Codable structs that worked fine before adding CloudKit capability. I believe they are the reason I started seeing errors after enabling CloudKit. Example model: @Model final class ProtocolMedication { var times: [SchedulingTime] = [] // SchedulingTime is Codable // other properties... } After enabling CloudKit, I get this error logged to the console: 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release CloudKit Console shows this times data as "plain text" instead of "bplist" format. Other struct/enum properties display correctly (I think) as "bplist" in CloudKit Console. The local SwiftData storage handled these arrays fine - this issue only appeared with CloudKit integration. What's the recommended approach for storing arrays of Codable structs in SwiftData models that sync with CloudKit?

Is the Notary service unavailable again? The system-status page shows it as being green but I am back to receiving the same error as previously which fixed itself once the notary service went green again and I am unable to notarize and staple my Distribution PKG.
