Missing com.apple.developer.adservices entitlements
I am trying to build my app and want to be able to integrate with apple ads services so I can get my users attribution token. I tried a added the "com.apple.developer.adservices" entitlement but now that I build my app it fails with the following error include the com.apple.developer.adservices entitlement. Profile qualification is using entitlement definitions that may be out of date. Connect to network to update. What do I need to do to make this work, I tried and cant fina any docs online

In Core Spotlight, it requires four consecutive characters to index the content. Only through title or displayName can the content be indexed.
In Core Spotlight, one can only index content by using title or displayName, and it requires four consecutive characters for indexing. These situations occurred in iOS 17 and 18. In iOS 16, I could not only index content by title or displayName, but also by keyword. Moreover, there was no restriction of requiring four consecutive characters. I could index my app content by simply inputting one character. Here is my code.https://github.com/kritto1/corespotlight-bug-test/tree/main @available(iOS 14, *) func addItemToIndex(_ item: QSpotlightItem) { let attributeSet = CSSearchableItemAttributeSet(contentType: .item) attributeSet.title = item.title attributeSet.displayName = item.title attributeSet.contentDescription = item.contentDescription attributeSet.keywords = item.keywords attributeSet.thumbnailData = item.thumbnailImage attributeSet.contactKeywords = item.keywords attributeSet.supportsNavigation = true let searchableItem = CSSearchableItem(uniqueIdentifier: item.id, domainIdentifier: "com.qunar.iphone.spotlight", attributeSet: attributeSet) searchableItem.expirationDate = .distantFuture CSSearchableIndex.default().indexSearchableItems([searchableItem]) { error in if let error = error { } else { } } } @available(iOS 14, *) func addToSpotlightIndex() { let spotlightHotel = QSpotlightItem( id: "corespotlight_1", title: "查询酒店住宿", contentDescription: "", thumbnailImage: UIImage(named: "img2")?.pngData(), keywords: ["酒店", "住宿"] ) addItemToIndex(spotlightHotel) let spotlightFlight = QSpotlightItem( id: "corespotlight_2", title: "查询和预订机票", contentDescription: "", thumbnailImage: UIImage(named: "img2")?.pngData(), keywords: ["查询", "预订", "机票"] ) addItemToIndex(spotlightFlight) let spotlightSight = QSpotlightItem( id: "corespotlight_3", title: "查询预订门票", contentDescription: "", thumbnailImage: UIImage(named: "img2")?.pngData(), keywords: ["查询", "预订", "门票"] ) addItemToIndex(spotlightSight) }

Running a Child Process with Standard Input and Output
IMPORTANT Rather than use the code below, I recommend that you adopt Swift’s shiny-new Subprocess package. That’s what I’m doing! (-: Running a child process using Process (or NSTask in Objective-C) is easy, but piping data to and from the child’s stdin and stdout is surprisingly tricky. I regularly see folks confused by this. Moreover, it’s easy to come up with a solution that works most of the time, but suffers from weird problems that only show up in the field [1]. I recently had a couple of DTS incidents from folks struggling with this, so I sat down and worked through the details. Pasted below is the results of that effort, namely, a single function that will start a child process, pass it some data on stdin, read the data from the child’s stdout, and call a completion handler when everything is done. There are some things to note here, some obvious, some not so much: I’ve included Swift and Objective-C versions of the code. Both versions work the same way. The Swift version has all the comments. If you decide to base your code on the Objective-C version, copy the comments from there. I didn’t bother collecting stderr. That’s not necessary in many cases and, if you need it, it’s not hard to extend the code to handle that case. I use Dispatch I/O rather than FileHandle to manage the I/O channels. Dispatch I/O is well suited to this task. In contrast, FileHandle has numerous problems working with pipes. For the details, see Whither FileHandle?. This single function is way longer than I’d normally tolerate. This is partly due to the extensive comments and party due to my desire to maintain focus. When wrapping Process it’s very easy to run afoul of architecture astronaut-ism. Indeed, I have a much more full-featured Process wrapper sitting on my hard disk, but that’s going to stay there in favour of this approach (-: Handling a child process correctly involves some gnarly race conditions. The code has extensive comments explaining how I deal with those. If you have any questions or comments about this, put them in a new thread. Make sure to tag that thread with Foundation and Inter-process communication so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" [1] Indeed, this post shows that I’ve made this sort of mistake myself )-:

The menu can't be shown in background process in MacOS 26(beta)
After I upgraded to MacOS 26(beta), my program caused the system to pop up a window as shown in the following picture. My application is a process with only a tray icon. I found that my tray icon is not displayed in the current version, even though I clicked the "Always Allow" button. Here are my questions: 1.Will this related feature remain consistent in the official release? 2.How can I create a cmd process that only displays a system tray icon (no main window) like Alfred?

Change default handler for tel URL scheme on macOS
My app is a VoIP softphone for Mac that allows people to make phone calls to a regular phone numbers. The app exists since before Mac App Store. The app declares itself to the system as capable of handling tel: URLs. Until now, people could change the default handler for tel URLs in FaceTime settings (Default for calls). In macOS Tahoe 26, this doesn't seem to be possible any more. That option is gone from the FaceTime settings. Is it completely gone or has it been moved somewhere else? If there is no UI control for this any more, is it possible to change it programmatically?

Inquiry About Deferred Deep Link Limitation and Alternative Options
Dear Apple Support Team, I hope this message finds you well. I’m reaching out to inquire about the limitations of deferred deep linking within iOS applications. Specifically, I’m interested in understanding the constraints and challenges that prevent deferred deep links from functioning as expected in certain scenarios (e.g., when the app is not installed or other related issues). Additionally, I would like to ask if there are any recommended alternative approaches or solutions to implement deep linking, ensuring that users can still be directed to specific content or screens even if they need to install the app first. Your insights and guidance would be greatly appreciated as I work to enhance the user experience in my app. Thank you for your time and assistance. Best regards, Santosh

Question about App Clip Update Behavior
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.

Spotlight Importer Extension Not Triggered for Custom UTI on macOS
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.

How to test Declared Age Range functionality
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?

ExtensionFoundation on iOS 26
Hi, I'm trying to add an extension to my app on iOS 26. I've followed the instructions on https://developer.apple.com/documentation/extensionfoundation/adding-support-for-app-extensions-to-your-app and made it as far as being able to launch the extension: let monitor = try await AppExtensionPoint.Monitor(appExtensionPoint: .localWebServerExtension) currentIdentity = monitor.identities.first if let currentIdentity = currentIdentity { let myConfig = AppExtensionProcess.Configuration(appExtensionIdentity: currentIdentity, onInterruption: { NSLog("extension was terminated") }) myProcess = try await AppExtensionProcess(configuration: myConfig) myConnection = try myProcess?.makeXPCConnection() } None of these calls throw, and when I examine myProcess from inside that code, it seems to be normal (there's a pid, for example). Yet the code inside my extension seems to not be executed: breakpoints are not triggered, NSLog() calls do not appear on the console. The onInterruption() callback is also not triggered, or at least it does not appear on the console either. I've probably missed something obvious, but what could it be?

Access resource in swift package from xcframework
I have an iOS app that includes a local Swift package. This Swift package contains some .plist files added as resources. The package also depends on an XCFramework. I want to read these .plist files from within the XCFramework. What I’d like to know is: Is this a common or recommended approach—having resources in a Swift package and accessing them from an XCFramework? Previously, I had the .plist files added directly to the main app target, and accessing them from the XCFramework felt straightforward. With the new setup, I’m trying to determine whether this method (placing resources in a Swift package and accessing them from an XCFramework) is considered good practice. For context: I am currently able to read the .plist files from the XCFramework by passing Bundle.module through one of the APIs exposed by the XCFramework.

CXCallDirectoryManager.openSettings() No Longer Opens “Call Blocking & Identification” in iOS 26
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.

How to find renamed app using old name in Spotlight?
We are planning on renaming our app. The new name is not like the current name. It will be renamed in the App Store as well as the App display name. Yet, we still want new and existing users to be able to find the app by using the old name in search/spotlight under iOS. A great example of this is entering Twitter to find the X app and it shows up in the App section in the Spotlight search. Are there any guidelines, settings, or tricks for doing this? Some have suggested adding a Spotlight search term but that will not have it show up in the App section I fear.

LiveCommunicationKit
What I want to achieve now is that when the app is not running, upon receiving a notification, it displays an interface similar to CallKit with accept and decline buttons. Here is part of my code: @available(iOS 17.4, *) class LiveCommunicationManager: NSObject, ConversationManagerDelegate { static let shared = LiveCommunicationManager() var isInvalidate:Bool = false var configuration: ConversationManager! override init() { let config = ConversationManager.Configuration( ringtoneName: "notes_of_the_optimistic", iconTemplateImageData: UIImage(named: "AppIcon")?.pngData(), // 图标的 PNG 数据 maximumConversationGroups: 1, // 最大对话组数 maximumConversationsPerConversationGroup: 1, // 每个对话组内最大对话数 includesConversationInRecents: false, // 是否在通话记录中显示 supportsVideo: false, // 是否支持视频 supportedHandleTypes: [.generic,.phoneNumber,.emailAddress] // 支持的通话类型 ) configuration = ConversationManager.init(configuration: config) } func reportIncomingCall(uuid: UUID, callerName: String) { configuration.delegate = self let local = Handle(type: .generic, value: callerName, displayName: callerName) let update = Conversation.Update(localMember: local,members: [local],activeRemoteMembers: [local]) Task{ do { try await configuration.reportNewIncomingConversation(uuid: uuid, update: update) print("成功报告新来电") } catch { print("报告新来电失败: \(error.localizedDescription)") } } } func conversationManager(_ manager: ConversationManager, conversationChanged conversation: Conversation) { print("会话状态改变了") } func conversationManagerDidBegin(_ manager: ConversationManager) { print("会话已经开始了") manager.delegate = self } func conversationManagerDidReset(_ manager: ConversationManager) { print("会话将要清除了") } func conversationManager(_ manager: ConversationManager, perform action: ConversationAction) { print("会话接听了") configuration.invalidate() } func conversationManager(_ manager: ConversationManager, timedOutPerforming action: ConversationAction) { print("会话超时了") } func conversationManager(_ manager: ConversationManager, didActivate audioSession: AVAudioSession) { print("会话激活了") } func conversationManager(_ manager: ConversationManager, didDeactivate audioSession: AVAudioSession) { print("会话死亡了") } } 在Appdelegate里设置了这些: func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { // 在这里处理离线推送通知 completionHandler(.noData) // 返回后台任务完成 if let aps = userInfo["aps"] as? [String: Any], let alert = aps["alert"] as? [String : Any]{ // 静默推送的处理逻辑 if #available(iOS 17.4, *) { let manager = LiveCommunicationManager.shared if manager.isInvalidate { return } if let msgType = userInfo["msgType"] as? Int{ if msgType == 5{ manager.configuration.invalidate() }else{ let callerName = alert["title"] as? String ?? "Fanvil" manager.reportIncomingCall(uuid: UUID(), callerName: callerName) } } } } } Xcode has been configured with the necessary capabilities, such as Background Fetch, Voice over IP, Background Processing, and Push Notification. The issue now is that sometimes the code works as expected, allowing the app to wake up when not running and displaying the system interface with accept and decline buttons. However, after a few successful attempts, the app stops waking up, and no notification appears. But when I manually open the app, the didReceiveRemoteNotification method gets triggered. I’d like to know why this stops working after a few times.

WeatherKit failing on JWT Error
My app AirCompare has been in the app store and successfully using WeatherKit to fetch weather since it became available.

Universal links: Open in "MyApp" doesn't launch my app
I've a strange problem which is only occurring on 2 client devices. We have enabled Universal links, and have it fully tested and working. On one client device, the link never opens our app; but here's the strange thing: If I long-press on our link (in Messages), it gives a preview (as expected), and the context menu offers "Open in ", as well as "Open in Safari". Tapping on "Open in " does nothing. I've tried the following: Checked I could access the site-association file over https with no redirects Enabled developer mode and used universal link debug feature: pasted the same link - Developer mode says it will open the app. I've carried out the sysdiagnose; And there are entries in there for our app in swcutil_show.txt. Snipped below: Service: applinks App ID: <my fully qualified app bundle id> App Version: 760.0 App PI: <LSPersistentIdentifier 0x6b8008930> { v = 0, t = 0x8, u = 0x45c, db = DC8D18A2-430D-4AD4-A5BE-B7A003CF9A6F, {length = 8, bytes = 0x5c04000000000000} } Domain: www.<mydomain>.com Patterns: {"/":"/cc/*"}, {"?":{"t":"*"},"/":"/md/"} User Approval: unspecified Site/Fmwk Approval: approved Flags: Last Checked: 2025-04-29 09:10:21 +0000 Next Check: 2025-05-04 08:42:50 +0000 -------------------------------------------------------------------------------- Service: applinks App ID: <my fully qualified app bundle id> App Version: 760.0 App PI: <LSPersistentIdentifier 0x6b8008930> { v = 0, t = 0x8, u = 0x45c, db = DC8D18A2-430D-4AD4-A5BE-B7A003CF9A6F, {length = 8, bytes = 0x5c04000000000000} } Domain: <mydomain>.com Patterns: {"/":"/cc/*"}, {"?":{"t":"*"},"/":"/md/"} User Approval: unspecified Site/Fmwk Approval: approved Flags: Last Checked: 2025-04-29 09:10:21 +0000 Next Check: 2025-05-04 08:42:50 +0000 -------------------------------------------------------------------------------- Service: applinks App ID: <my fully qualified app bundle id> App Version: 760.0 App PI: <LSPersistentIdentifier 0x6b8008930> { v = 0, t = 0x8, u = 0x45c, db = DC8D18A2-430D-4AD4-A5BE-B7A003CF9A6F, {length = 8, bytes = 0x5c04000000000000} } Domain: *.<mydomain>.com Patterns: {"/":"/cc/*"}, {"?":{"t":"*"},"/":"/md/"} User Approval: unspecified Site/Fmwk Approval: approved Flags: Last Checked: 2025-04-29 09:10:21 +0000 Next Check: 2025-05-04 08:42:50 +0000 -------------------------------------------------------------------------------- The version numbers match the installed version of my app I've tried running logging and just capturing logs before and after I press the "open in ", but there's nothing suspicious in there. And the kicker - it's only happening on a single device. No other devices are experiencing this.

Rosetta 2 - Build 1.0.0.0.1.1744447383
Goal: Manually install an explicit version of Rosetta2 Background: Me and some customers have an old app (intel) which perfectly worked with Rosetta2. In the last week of April most macheines were updated to Mac Os 15.4.1. and the app still starts but certain functionality is bronken. Some fields ind the forms don't write back to the database, some data can't be read from the database. (Most installations will fade out over the next month but it would be great to have the app fully working for data migration.) First try was to step back to 15.4. (Clean Install - Install App - Rosetta installs as expected): no change, app still broken Second try back to 15: (Clean Install - Install App - Rosetta installs as expected): App still broken (!) This is interesting as the app worked for month using Mac Os 15! Third try: Back to MacOS 14 (Clean Install - Install App - Rosetta installs as expected): App is working like nothing happend. (All attempts on same hardware of course.) Reasoning: Rosetta2 was the only software (besides the app itself) installed after clean MacOS installs. Now, my guess is that there were might be a change in Rosetta2 as the app worked on MacOs 15 up the update 15.4.1. was installed. Checking versions (pkgutil --pkg-info com.apple.pkg.RosettaUpdateAuto): Rosetta version MacOS 14: 1.0.0.0.1.1722778371 Rosetta version on MacOS 15.4.1: 1.0.0.0.1.1744447383 To fully verify the cause it would be great to uninstall Rosetta on MacOS15.4.1 machine and explicit install lower version (1.0.0.0.1.1722778371) which must be available somewhere as MacOS14 still gets this version. I know how to uninstall - is there a possibility to manually install an explicit version of Rosetta2?

How to protect endpoints used by Message Filtering Extension?
Hi, I am just wondering if there is any option to protect my endpoints that will be used by Message Filtering Extension? According to the documentation our API has 2 endpoints: /.well-known/apple-app-site-association /[endpoint setup in the ILMessageFilterExtensionNetworkURL value of the Info.plist file] that the deferQueryRequestToNetwork will request on every message Since all requests to these 2 endpoints are made by iOS itself (deferQueryRequestToNetwork), I don't understand how I can protect these endpoints on my side, like API key, or maybe mTLS. The only way that I found is white list for Apple IP range. Is there other methods for it?
