Hi, I'm currently working on an app made originally for iOS 15. On it, I add an observer on viewDidLoad function of my ViewController to listen for changes on the UserDefault values for connection settings. NotificationCenter.default.addObserver(self, selector: #selector(settingsChanged), name: UserDefaults.didChangeNotification, object: nil) Said values can only be modified on the app's section from System Settings. Thing is, up to iOS 17, the notification fired as expected, but starting from iOS 18, the notification doesn't seem to be sent by the OS. Is there anything I should change in my observer, or any other technique to listen for the describe event? Thanks in advance.

Hello! We're currently testing Live Caller ID implementation and noticed an issue with userIdentifier values in our database. Initially, we expected to have approximately 100 records (one per user), but the database grew to about 10,000 evaluationKey entries. Upon investigation, we discovered that the userIdentifier (extracted from "User-Identifier" header) for the same device remains constant throughout a day but changes after a few days. We store these evaluation keys using a composite key pattern "userIdentifier/configHash". All these entries have the same configHash but different userIdentifier values. This behavior leads to unnecessary database growth as new entries are created for the same users with different userIdentifier values. Could you please clarify: Is this the expected behavior for userIdentifier to change over time? If yes, is there a specific TTL (time-to-live) for userIdentifier? If this is not intended, could this be a potential iOS bug? This information would help us optimize our database storage and implement proper cleanup procedures. Thank you for your assistance!

On iOS 26, calling CXCallDirectoryManager.sharedInstance.openSettings() does not navigate to the “Call Blocking & Identification” settings page as documented. Instead, it either opens the main Phone settings page or fails to navigate entirely. This breaks the expected behavior for enabling Call Directory extensions and impacts onboarding flows for apps using CallKit. Expected: Settings should open directly to Phone → Call Blocking & Identification. Actual: Navigates to the main Phone settings page This appears to be a regression from previous iOS versions. Documentation still states this API should open the correct page.

Hello all, I'm finding myself with a compile error when trying to use a defined UTType for Transferable conformance when the type is also an AppEntity. The compiler error is Could not determine the identifier of `.todo`. Please use a UTType defined by the UniformTypeIdentifiers framework However, said compiler error only shows up after adding AppEntity conformance. So, in order to reproduce: Create any type, conform to Codable struct Todo: Codable { var id: UUID var title: String var completed: Bool } Create a UTType extension for the new type extension UTType { public static let todo: UTType = UTType(exportedAs: "org.nameghino.types.todo") } Add Transferable conformance extension Todo: Transferable { static var transferRepresentation: some TransferRepresentation { CodableRepresentation(contentType: .todo) ProxyRepresentation(exporting: \.title) } } At this point, the code compiles correctly on Xcode 16.2 beta 2 (16C5013f) Add AppEntity conformance extension Todo: AppEntity { static var typeDisplayRepresentation: TypeDisplayRepresentation = "todo_title" static var defaultQuery = Todo.Query() var displayRepresentation: DisplayRepresentation { DisplayRepresentation(title: "\(title)") } struct Query: EntityQuery { typealias Entity = Todo init() {} func entities(for identifiers: [UUID]) async throws -> [Todo] { return [] } func suggestedEntities() async throws -> [Entity] { return [] } } } Now the code is not compiling with the aforementioned error.

We're having trouble with getting Siri to hand off specific trigger words to our app via shortcuts. I want to be able to say "Hey Siri Myappname Foobar" but in some cases if Foobar is the name of a specific business it may launch maps instead showing locations of those businesses. Is there any way to inform Siri, "no, *****, launch our app as the shortcut specifies!"

Hi, I'm trying out the beta for music kit. In the current version of my app, my widget can show multiple albums. I preload the images of the album covers. In the beta's the url that is returned for the artwork starts with: "musickit://", which does not work with URLSession. How can I preload the data using the new url scheme? Current code:     func fetchArtworkFor (musicID: MusicItemID, url : URL?) async throws -> UIImage? {         guard let url = url else {             return nil         }         let urlRequest = URLRequest (url: url)         let data = try await URLSession.shared.data(for: urlRequest)         let image = UIImage(data: data.0)         return image     } // Some other function         for album in albumsToShow {             if let url = album.artwork?.url(width: context.family.imageHeight, height: context.family.imageHeight), let image = try? await fetchArtworkFor(musicID: album.id, url:url) {                 images[album] = image             }         }

With the Live Caller ID example server, the caller lookup dataset is defined in an input.txtpd and processed by running a ConstructDatabase command which creates a block.binpb and an identity.binpb file. In other words, a static input file is being processed into static block and identity files. However, in the real world, the data content for identified and blocked numbers is something which is in a constant state of flux and evolution, as new numbers becoming available, old ones become stale, numbers which were initially considered safe change into being considered malicious etc. etc. Is the example server just that, merely an example using fixed datasets, and an actual production server is able to use live every changing data to formulate its response back to the iPhone OS query? Here's a concrete use case - suppose it's a requirement to permit US nanp numbers but to block anything else. The total number of non US nanp numbers is so large and ever changing that it would be unfeasible to attempt to capture them in an input.txtpd file and then process that, and then to re-capture and re-process it endlessly. Instead what would be required is the ability for the Live Caller ID server to evaluate at query time, using a regular expressions for example, if a number is nanp or not. Is this possible?

Issue with App Clip Card Showing "App Clip unavailable" for DIGI LIVE App In my DIGI LIVE application, I have an App Clip configured for iOS 17.6+ (the file exceeds the 15 MB limit), and I have made all the necessary preparations for the App Clip to work correctly. However, the App Clip card constantly displays an "App Clip unavailable" error for various users (depending on their system language). The URL associated with the App Clip invocation is: https://ar.digi-live.de The AASA file is located at /.well-known/apple-app-site-association and contains the required fields for the App Clip: { "applinks": { "details": [ { "appIDs": ["N9QR6LF765.de.digilive.app"], "components":[ { "#": "no_universal_links", "exclude": true, "comment": "Matches any URL whose fragment equals no_universal_links and instructs the system not to open it as a universal link" }, { "/": "*", "comment": "Matches any URL like ar.digi-live.de" } ] } ] }, "appclips": { "apps": ["N9QR6LF765.de.digilive.app.Clip"] } } If I use the default App Clip link (https://appclip.apple.com/id?p=de.digilive.app.Clip) to launch it, the "App Clip unavailable" error no longer appears. But if I delete the App Clip from the settings, the error comes back, and it can only be launched again using the default link. It feels like the problem is with the App Clip loading at the moment the App Clip card is triggered — it simply fails to load. Video https://storage.yandexcloud.net/mmrs/files/digilive/IMG_2259.mp4

Hello, I would like to understand the update behavior for App Clips. Let's consider a scenario where a user has an App Clip on their device from a previous interaction. If I, as the developer, then publish a new version of the App Clip to the App Store, what is the expected behavior? My main questions are: Will the App Clip be automatically updated in the background? Or, is user action required to get the new version, for example, by deleting the old one and re-launching it from a Smart App Banner or QR code? Any information on this process would be greatly appreciated. Thank you.

Noticing a few issues with Screen Savers in macOS Tahoe developer beta 1 : The command open x-apple.systempreferences:com.apple.ScreenSaver-Settings.extension no longer works to open the Screen Savers preference pane. The reason? There is no longer a Screen Saver preference pane - it still exists, but it's now a Modal dialog (that can not be resized) that is opened from within the Wallpaper preference pane, by clicking a button. Something funny is happening with legacyScreensaver - I think that ScreenSaverView.Init(frame:isPreview) may be passing wrong values, e.g. the isPreview boolean is false in Preview mode? I've submitted Feedback # FB17895600 about some of these, and will report back more as I figure things out. Please feel free to add to this thread, thanks!

How can experimentation and testing calling the AgeRangeService.shared.requestAgeRange() functionality be recreated easily? The very first time I ran this the OS popped up a dialog, however it won't do so again, even after the app is deleted and the device re-started. If one navigates to Settings/User/Personal Information/Age Range for Apps/Apps that have requested your age range appear here. Then the names of apps appear here even after the app has been deleted. Therefore how can it be removed from this section? Erasing and resetting the phone will presumably reset things back to a state such that the dialog can be presented again. But doing that and having to wait for that to complete each development or test run is impractical. Is there an alternative?

On macOS 26, I've run into a situation when a user “customizes” a folder icon with Finder by assigning/changing an SF Symbol or an emoji, QLThumbnailGenerator keeps returning the stale initially retrieved folder icon (no matter whether it had been customized or not) until my app quits. After the app is re-launched, the icon is correctly retrieved once again. let generator = QLThumbnailGenerator.shared let size: CGSize = CGSize(width: 64, height: 64) let request = QLThumbnailGenerator.Request(fileAt: url, size: size, scale: NSScreen.main!.backingScaleFactor, representationTypes: .icon) request.iconMode = true do { let thumb = try await generator.generateBestRepresentation(for: request) thumb.nsImage.size = size return thumb.nsImage } catch { print("generateThumbnail: \(error)") return nil } It seems like the QuickLook Thumbnailing cache does not invalidate automatically upon folder customization. Is there any way to manually invalidate the QuickLook Thumbnailing cache?

We are not receving incoming call from blocked numbers below iOS 26 versions but same in iOS 26 onwards we are receiving the incoming call.. Can you please provide any solutions to fix the issue

Hi all, I'm trying to add Spotlight support to a macOS app that handles custom virtual machine bundles with the .vpvm extension. I’ve followed the current documentation and used the modern CSImportExtension approach with a Spotlight Importer extension target. Here’s what I’ve done: App Info.plist: Declared com.makeprog.vpvm as a UTI conforming to com.apple.package. Registered it under UTExportedTypeDeclarations and CFBundleDocumentTypes. Spotlight Importer Extension: Added a new macOS target using the Spotlight Import Extension template. Set the NSExtensionPointIdentifier to com.apple.spotlight.import. Used CSSupportedContentTypes = com.makeprog.vpvm. Implemented a minimal update(_ attributes:forFileAt:) method that sets displayName, title, and contentDescription. Other steps: Verified that the .appex is embedded under Contents/PlugIns/. Confirmed it appears in mdimport -e output with correct UTI. Used mdimport -m -d2 -t /path/to/file.vpvm, but I still get: Imported '/path/to/file.vpvm' of type 'com.makeprog.vpvm' with no plugIn. The extension is never invoked. I’ve also tried: Ensuring the .vpvm file is a valid directory bundle. Restarting Spotlight / rebuilding index. Ensuring the app and extension are properly signed. Tried installing the app in test virtual machine Question: Has anyone successfully used CSImportExtension for custom UTIs? Is there something additional I need to do for the extension to be recognized and triggered? Any advice or examples would be greatly appreciated! Thanks in advance.

In mainland China, CallKit is not available. Recently, I discovered LiveCommunicationKit. Can it replace CallKit? There is no relevant introduction in the documentation. Can someone help me understand how to use it? https://developer.apple.com/documentation/livecommunicationkit

On macOS, one can set the "Open With ..." application in the information panel of a file without changing the default for this file type. However, doing this for a number of files is very tedious. A simple case is to change all .txt files in a directory to a special editor, but leave the system wide default (usually TextEdit). I have tried AppleScript, command line tools as well as a minimal GUI app (using LSSetItemAttribute), but all fail because of a lack of permission. Is there any way to achieve this?

I'm working on adding MetricKit to our iPad application that we distribute internally via Enterprise distribution. I've set up the didReceive functions for both MXMetricPayload and MXDiagnosticPayload. When I build onto a device via Xcode and use the Simulate MetricKit Payloads command, everything works as expected. The issue I'm having is when testing on a device via our enterprise distribution. When I simulate a crash, I am receiving the MXDiagnosticPayload so that part is working correctly. However, I am never receiving a MXMetricPayload. I've been using the app and waiting up to 3 days in some tests and not receiving any payload over that time frame. Some information I found suggested the issue might be MetricKit not working fully on enterprise apps but I haven't been able to find a definitive source on that question. Hoping someone here can guide me on that. Thanks!

Hello! What is the TTL for evaluation key(s) used in Live Caller ID feature on iOS client side? We would like to align our server-side key storage TTL with the iOS client implementation to optimize memory usage. Would really appreciate your help on this.

I have published the app on the App Store along with its corresponding app clip, my app clip is configured with some advanced experiences for each one of my clients, but whenever some users try to scan an NFC or QR Code they see the card rendering correctly with their configured banner image, but with the message "App Clip Unavailable". The weird thing is that both iMessage and the website to which the associated domain is set and the apple-app-site-association is stored, renders the banner or card correctly, and when the users tap the banner or card they open the advanced app clip experience correctly without any issue. I have attempted to troubleshoot the issue by checking the following: if the app clip is below 15MB if we are using a second level domain in my associated domain both for my app clip and app (excluding the www subdomain). checking if the AASA is correctly stored inside .well-known directory checking the configuration for the advanced experience I opened a case: 102233443873, and added a bunch of videos and screenshot showcasing the issue, but I have not yet received a reply

Hi, Since I updated my phone to 23A341, my Call filtering app is not blocking calls anymore. Same release checked on iOS 18 phone, it is working. I still see the callkit logs into the Console showing that numbers are loaded into the iOS-managed SQlite DB but the calls are not blocked nor identified. Anyone with the same issue? BR
