I'm building a planner app (React inside a Capacitor WKWebView shell). People handwrite and draw with the Pencil, and they also type longer notes on the keyboard. We want Scribble on, and we don't want to be forced into the small floating keyboard that comes with it. Ideally the user picks which keyboard they get. What I'm seeing on an iPad MU162LL, iPadOS 26.7, Apple Pencil 1: Tap a text field with the Pencil. A stray "." or "," gets typed, which looks like Scribble reading the tap as handwriting. Only the small Pencil toolbar shows up (Scribble tool, up/down chevrons, mic, return). Its menu has Pencil Settings, Minimize, Show Keyboard and Show Emoji. Show Keyboard brings up only the small floating keyboard. Pinching it open or dragging it to the bottom doesn't dock it. The menu on the keyboard's key only offers Hide Keyboard and Pencil Settings, with no Dock or Full. It stays that way until I force quit the app. After a relaunch, a finger tap gives the normal docked keyboard, until I use the Pencil in a field again. Sometimes, not every time, a finger tap after that also gets the floating keyboard. I haven't found a pattern. It isn't specific to my app. It happens in Safari on google.com's search box, on an old build of my app from before any Pencil related code, and on another person's iPad. In Notes, the keyboard docks normally after Pencil use. On the app side I've ruled out the Capacitor keyboard plugin's accessory bar handling, toggling inputmode="none", blurring and refocusing from JS, and the scene and Info.plist settings. No hardware keyboard is involved. Most threads I found end at turning Scribble off. I tried that: with Scribble off, I force quit the app and reopened it, and the state was gone. Turning it off doesn't help us, since handwriting is the point. What I've looked at so far: WebKit's WKContentView installs its own UIIndirectScribbleInteraction and is its own delegate, so I don't see a hook there. UIScribbleInteraction shouldBeginAt would suppress Scribble, but it also kills handwriting in the field. I haven't tried it on the web view yet, and I don't know whether an interaction on the WKWebView or its content view would be consulted for web content. UIScribbleInteraction.isPencilInputExpected and UITextInputContext look read only. I can detect the state but not change it. UIKeyboardLayoutGuide.followsUndockedKeyboard only helps layout. Questions: Is there a supported way for an app, or a web page in WKWebView, to ask for the docked keyboard, or to leave the Pencil input state, while keeping Scribble available? Is it intended that the state lasts for the whole app session, and that a finger tap can also get the floating keyboard afterwards? If there's no such API, is UIScribbleInteraction on the web view the intended way to opt a field out, and does it apply to web content? Feedback Assistant: [I'll file one and add the number here].

Hello, I found a visual bug in iOS 27 when using YouTube in the background. Steps: Play a video on YouTube. Lock the iPhone while the video continues playing. Long-press the Lock Screen. Before the customization menu opens, observe the YouTube media player. Issue: The YouTube media player rapidly flickers/flashes approximately 10 times before the customization menu appears. Expected: The transition should be smooth without flickering. Device: iPhone 15 iOS: 27.0.1 I can provide a screen recording if needed. Thank you.

We ship a Live Caller ID Lookup extension (PIR-based) for spam call blocking. It works, and our PIR server is fast. But in practice, whether a call gets blocked depends on the quality of the user's internet connection at the moment the call arrives. The system waits only about 1 second for the blocking response. On a fast, stable connection it arrives in time. On an average or unstable connection it often doesn't, and the spam call rings through. So under the current platform limits we cannot guarantee blocking for every call. How we measured For each call we read the device syslog (CommCenter, CallDirectory, ciphermld, callservicesd) and our server logs. The extension cache was reset before each call, so every call triggered a real network lookup. All times are in ms and measured from addNewIncomingCall. Server-side processing of the PIR query was consistently 51–61 ms. The variance is almost entirely network transfer between the device and the server (or relay): In call D, HTTP/2 metrics show the ~28 KB request was handed to the network stack immediately (outbound_duration_ms=0), but response headers arrived only after 2216 ms. In call E, the device waited ~660 ms between finishing the upload to the relay and receiving the first byte of the response. Connection setup on a new connection cost 176–271 ms (DNS + TCP + TLS, or a QUIC handshake to the relay). Before the first byte was sent, the system spent another 54–225 ms after the call arrived. In the failing cases the syslog shows: CallDirectory: not all blocking fetches returned within 1 second(s) callservicesd: shouldBlock: NO shouldSilence NO The block response (shouldBlock=1) then arrives 100–1500 ms too late, and the call keeps ringing. What works: repeat calls After the first lookup the result is cached on the device. A repeat call from the same number is silenced without contacting the server, whatever the connection speed. In our logs, follow-up calls from the same number were silenced within ~65 ms of addNewIncomingCall, with no network request. So a user may get the first spam call from a number but not the next ones. The first call, though, is exactly the one users complain about. The problem with the 1-second budget Each blocking lookup has to: Send a PIR query Receive a response of ~22–25 KB. Often open a new TLS/QUIC connection through the OHTTP relay. All of this has to fit into about 1 second, together with the system's own overhead before the request is sent. On a good connection that takes about 250–650 ms. On an average mobile or congested Wi-Fi connection it easily goes past 1 second, and nothing the developer can optimize on the server helps. Our server already responds in about 50 ms.

(lldb) p [@"ΗΙzzz" caseInsensitiveCompare:@"ᾚabc"] (long long) -1 (lldb) p [@"ᾚabc" caseInsensitiveCompare:@"ΗΙzzz"] (long long) -1 Note the unicode char in the second string. The results can't be both -1, afaik, if one is -1 the other one should be +1. This causes inconsistent indexing in a sorted array resulting in obscure crashes of my app. Am I doing something wrong? Tested on iOS 27 and macOS 26.6.

I have an app that I am implementing background assets, using self hosted unmanaged. Everything compiles fine, and I get no errors. But I can't figure out how to trigger the 'install' phase into the extension. I have tried copying the app into /Applications without luck. I have deleted the entire DerivedData and all copies of the application. Nothing seems to work. I tried using the Apple provided sample app from here and got the same results. I don't understand why the CLI tool backgroundassets-debug only works with iOS based connected devices? Please let me know how can I test my BADownloaderExtension on Mac via XCode. Thank you.

My share extension accepts a shared location and I want to bring the user into the containing app at the corresponding map screen. I understandNSExtensionContext.open(_:completionHandler:) is restricted to Today widgets per the App Extension Programming Guide, and I observe it reporting success == false. The technique I am asking about is different: walking the extension's responder chain to obtain the UIApplication instance, then calling open(_:options:completionHandler:) on it. In a minimal sample this launches the containing app and the completion handler reports success == true, on both iOS 26 and iOS 27. What makes this worth asking rather than assuming: It never references UIApplication.shared, which is annotated NS_EXTENSION_UNAVAILABLE_IOS. open(_:options:completionHandler:) itself carries no extension-unavailable annotation in the SDK, so the call compiles cleanly even with APPLICATION_EXTENSION_API_ONLY = YES. I am aware of https://developer.apple.com/forums/thread/773342, where an Apple Frameworks Engineer wrote that "There's no supported way for you to launch your app directly from App Extensions, except Today and Widgets." That thread does not cover the responder chain specifically, which is why I am asking. My questions: a) Is this permitted? Is obtaining UIApplication via the responder chain from a Share Extension and calling open(_:options:completionHandler:) considered a violation of App Store Review Guideline 2.5.1 (public APIs used as intended), independent of whether it currently functions? b) If it is not permitted, what is the recommended way for a Share Extension to hand a location to its containing app such that the user arrives at the relevant screen? The code in question, in its entirety: @objc private func openUsingResponderChain() { var responder: UIResponder? = self while let currentResponder = responder { if let application = currentResponder as? UIApplication { application.open(targetURL, options: [:]) { [weak self] success in self?.report("UIApplication via responder chain -> success = \(success)") } return } responder = currentResponder.next } report("No UIApplication found in the responder chain") } Full sample project: https://github.com/valtermak-voya/share-extension-open-url-repro A containing app registering opensample:// plus a share extension target built with APPLICATION_EXTENSION_API_ONLY = YES. The method above is the whole of the extension's logic. Filed with DTS as Case-ID 22452440.

We ship a ~6.2 GB Apple-hosted managed asset pack and request it with AssetPackManager.ensureLocalAvailability(of:). If the app goes to the background even once while the download runs, the transfer continues to the end and then fails with ManagedBackgroundAssetsProcessingPipeline.Dispatcher.PipelineNotFound. The system discards the resume data, and the next attempt starts again from byte 0. What the sysdiagnose shows: On backgrounding, backgroundassets.user logs allows BG activity, pausing any foreground downloads for background demotion and hands the download to nsurlsessiond. On return it logs re-promoted 1 previously-demoted foreground downloads. Each handoff moves the stream to another STExtractionService.privileged instance, which logs No processing pipeline with the ID "…" was found; defaulting to an extraction memory footprint of 50 MB. When the HTTP response ends: [Relay] No endpoint was found for the key "…" (fault) → The stream couldn't be finished: No processing pipeline with the ID "…" was found → Removing the resumption info → the download fails. This happened on every app-requested download that was backgrounded at least once. One run reached 100 % in the foreground and still failed. The only download that ever completed was the system's own prefetch download, which ran entirely in the background with the app never launched. Over one afternoon about 46 GB were downloaded for a single 6.2 GB pack. Questions: Is this a known issue with the demotion/promotion of foreground asset-pack downloads? Is AssetPack.download(for: nil) plus BADownloadManager.scheduleDownload(_:) a supported way to request a managed pack from the app, so the download never gets foreground priority? We're testing it now. Is there any other way to keep a download requested from a foreground app from being demoted? Filed as FB24888599.

Hello all, Looking for guidance for my app. I run a workout studio and the time frames for classes are all in military time. I have tried extensively to have this turned off and I am just unsure what is left to do. Has anyone dealt with something like this?

I'm getting a persistent WeatherKit authentication failure that survives every standard troubleshooting step. Hoping someone from the WeatherKit team can check the backend sync for my Team ID.

This looks like a backend entitlement sync issue between the Developer Portal and the WeatherKit auth service rather than a local configuration problem, since the signed entitlements are confirmed correct on my end. Could someone from the WeatherKit team check the sync status for this Team ID / Bundle ID and confirm whether WeatherKit token generation is enabled server-side? Happy to provide any additional diagnostic info (sysdiagnose, device logs, etc.) if needed. Thanks in advance!

We are currently verifying the functionality of CXSetTranslatingCallAction. We tested its implementation in a VoIP app—using Apple's Translate app by default—and confirmed that it works correctly in some instances. However, we have encountered an issue where, under certain conditions, the real-time translation feature becomes unavailable until the device is rebooted. The issue manifests as follows: When the real-time translation feature is enabled in CallKit, a beep sounds accompanied by the announcement "Starting translation," but the translation fails to proceed and terminates immediately. This behavior persists upon repeated attempts. Restarting the app does not resolve the issue; once this occurs, the feature remains unusable until the device itself is rebooted. Since the feature works normally after a device reboot, it does not appear to be a fundamental implementation error; I would like to investigate the root cause of this behavior. What information or steps are required to investigate this? I conducted the test using an iPhone 16 Pro running OS version 26.5. It is the same for both CallKit and LCK.

When I tap on one of the buttons in the ShieldAction extension I want to close the shield and open the parent app instead of the shielded app. Is there any way of doing this using the Screen Time API? class ShieldActionExtension: ShieldActionDelegate {      override func handle(action: ShieldAction, for application: ApplicationToken, completionHandler: @escaping (ShieldActionResponse) -> Void) {     // Handle the action as needed.           let store = ManagedSettingsStore()               switch action {     case .primaryButtonPressed:       //TODO - open parent app       completionHandler(.defer)     case .secondaryButtonPressed:       //remove shield       store.shield.applications?.remove(application)       completionHandler(.defer)         @unknown default:       fatalError()     }   }   }

Starting in iOS 27, opening a tel: URL that contains a call-forwarding MMI code from an app shows a system alert and dials nothing: Malicious Link Blocked: This link was blocked because it contains malware that will forward all of your incoming messages and calls to 1 (XXX) XXX-XXXX. Scammers often provide malicious links that look legitimate via email, text, or chat. On iOS 26 the same call showed the normal call confirmation prompt and the carrier applied the forwarding. Repro (in response to a button tap): UIApplication.shared.open(URL(string: "tel:*21*XXXXXXXXXXX%23")!) Typing *21*XXXXXXXXXXX# into the Phone app's keypad by hand still works on iOS 27, so the capability is still there; only the in-app handoff is blocked. This breaks setup for call-screening and visual-voicemail apps whose onboarding depends on carrier forwarding (*21*, *61*, *67*, *71*, *72). It also blocks the disable codes (##21#, ##004#, *73), so users can't turn forwarding off from inside the app, which works against the user's own safety. The anti-hijack intent makes sense for links arriving from Messages, Mail or Safari. For a user tap inside an installed App Store app, a confirmation sheet ("Forward calls to ...? Allow") seems like the right balance, and disable codes should always be allowed. Filed as FB24843805. Questions: Is this block meant to apply to links opened by an installed app in response to a user tap? Is there a supported API, entitlement or URL form to hand a forwarding code to the Phone app with user confirmation? Our current workaround is to copy the code to the clipboard and ask the user to paste it into the keypad, which is a real drop-off point for our (mostly older) users. If you're affected too, please file your own feedback and reference FB24843805.

Hi, I’m developing a macOS Finder Sync extension and noticed that NSMenuItem.separator() does not appear to render as a standard separator line when used inside the menu returned from FIFinderSyncController. In a normal AppKit NSMenu, the separator renders as expected. However, when the same kind of menu is returned from the Finder Sync extension, the separator appears as a blank/full-height empty row rather than a thin dividing line. Example: override func menu(for menuKind: FIMenuKind) -> NSMenu { let menu = NSMenu(title: "") menu.addItem(NSMenuItem( title: "First Action", action: #selector(firstAction(_:)), keyEquivalent: "" )) menu.addItem(NSMenuItem.separator()) menu.addItem(NSMenuItem( title: "Second Action", action: #selector(secondAction(_:)), keyEquivalent: "" )) return menu } Expected result: The separator should render as a normal macOS menu separator line between the two menu items. Actual result: In Finder’s context menu, the separator is displayed as blank vertical space / an empty menu row. I understand that Finder Sync menus are rendered by Finder and may not support every NSMenuItem feature. However, NSMenuItem.separator() is a very standard way to visually group menu commands, so I wanted to ask: Is this a known limitation of Finder Sync extension menus? Is there a supported way to display a real separator line in Finder Sync context menus? Should this be filed as a Feedback Assistant issue against Finder Sync / AppKit? I’m trying to avoid fake separators such as disabled menu items with "────" as the title, since that does not feel native and may not behave well with different fonts, accessibility settings, or appearance modes. Thanks!

The Problem When a user toggles radio buttons or checkboxes in a PDF using Preview, the widgets disappear following subsequent interactions after the file is saved and reopened. This renders the form fields unusable. Steps to Reproduce the Problem Open a PDF with radio buttons or checkboxes in Preview. Toggle a radio button or checkbox. Save and close the file. Re-open the PDF in Preview. Toggle the same button again. The button (and any others with the same field name) will disappear. Expected Results Toggling a radio button or checkbox should update the field value without causing the button (or related buttons) to disappear. This behavior is consistent with previous versions of PDFKit. What is Happening In Preview, interacting with radio buttons and checkboxes correctly updates their appearance as expected. Saving the PDF, however, causes the appearance dictionary to reference a new N entry that is a single appearance stream unassociated with any state. The annotation's AS entry is not updated. The original N entry remains but is no longer referenced. Subsequent interactions fail to update the visual presentation because the appearance stream is missing. Impact on User Experience Radio buttons and checkboxes may disappear and become unusable when toggled. PDF documents become irreparably altered after a button is toggled and the file is saved. PDF file size significantly increases when the file is saved. Users may believe they have successfully completed a form, only for the data to become inaccessible or invisible to recipients. Forms may need to be completely restarted or recreated from scratch if the original becomes unusable. The corrupted PDF structure might cause the file to render incorrectly or crash in third-party PDF viewers. Affected Apps/OSs Tested with Preview 11.0 (1147), as well as other apps that use PDFKit, on macOS Golden Gate 27.0 (26A428). This problem also affects PDFKit on iOS 27.0 and iPadOS 27.0.

The documentation for URLByDeletingLastPathComponent states the following: If the receiver’s URL represents the root path, this property contains a copy of the original URL. Otherwise, if the original URL has only one path component, this property contains the empty string. So maybe this is new in Foundation with the Golden Gate or maybe I just noticed this but the documentation above doesn't seem to be true. This will create an infinite loop: NSURL *fileURL = [NSURL fileURLWithPath:@"/Users/MyUsername/Desktop/AFolder" isDirectory:YES]; NSLog(@"%@",fileURL); NSURL *ancestorURL = fileURL.URLByDeletingLastPathComponent; while (ancestorURL != nil) { NSURL *nextAncestor = ancestorURL.URLByDeletingLastPathComponent; NSLog(@"Next: %@",nextAncestor); if ([nextAncestor isEqual:ancestorURL]) { NSLog(@"Hit the root - got a copy of the same url"); break; } else if ([nextAncestor.absoluteString isEqualToString:@""] || [nextAncestor.path isEqualToString:@""]) { NSLog(@"Empty string means we had only 1 path component."); break; } else if (nextAncestor == nil) { NSLog(@"Got nil"); break; } ancestorURL = nextAncestor; } The infinite loop can be avoided by adding the following condition: else if (nextAncestor.pathComponents.count == 1) { // One path component. NSURL *sneakPeak = nextAncestor.URLByDeletingLastPathComponent; NSLog(@"%lu",sneakPeak.pathComponents.count); // Logs 2. break; } When you get to one path component URLByDeletingLastPathComponent appends a .. path component rather than deleting a path component or returning a copy of the receiver or a url with an empty string.. If this sounds like a bug let me know. When I call URLByDeletingLastPathComponent on a url with only one path component I'd like to get nil. I think that would be a cleaner design.

Hello, We ship a font provider app that installs fonts system-wide on iOS, delivering the font files through On-Demand Resources. Since iOS 27 shipped, customers have been reporting that their installed fonts vanish from the system font list after every restart. I would like to know whether the restore path for system-wide font registrations changed in iOS 27, and what a font provider app is expected to do after a device reboot. Environment iOS 27.0 and 27.0.0 only. We have no reports on iOS 26 or earlier. iPhone 18 Pro and iPhone 18 Pro Max Fonts delivered through On-Demand Resources and registered for system-wide installation using CoreText Steps to reproduce Activate a font in the app. It appears in Settings > General > Fonts. Reboot the device. Without launching the app, open Settings > General > Fonts. The font is gone. The app still shows the font as active, because it keeps its own activation state. Deactivate and reactivate the font in the app. It comes back. Reboot again. It disappears again. This happens on every reboot. It also happens with a single font activated, and it persists after updating or reinstalling the app. Because the font is missing from the system font list, it is also missing in other apps that use system fonts. What we have ruled out Not low storage. These are new devices with plenty of free space. The documented purge trigger for On-Demand Resources is low storage, which does not explain a result this consistent. Not a crash. Our crash data for the affected app version shows no elevated crash rate on iOS 27 compared to iOS 18. Not specific to one font or one app version. Questions Did the restore path for system-wide font registrations change in iOS 27? Are registrations that reference files inside On-Demand Resources still restored at boot? If a font provider app now has to re-register after a reboot, when and how should it do that? There is no natural launch point, since someone may use the font in another app without opening ours first. Is there a supported way for the app to detect that a font it installed is no longer present in the system font list, so it can repair the registration quietly? Context We deliver several thousand fonts this way, and Apple increased our On-Demand Resources limit for that reason (Case-ID 17273913, December 2025). On-Demand Resources is deprecated as of iOS 27. We have separately confirmed that fonts delivered through Background Assets cannot be registered system-wide: registration fails with CTFontManagerErrorDomain code 306, both from the Background Assets container and after copying the files into the app sandbox, because CoreText requires the file to sit inside the app bundle or On-Demand Resources. We have a separate question open about that migration path, so this post is only about the reboot behavior on iOS 27. Happy to provide a sysdiagnose from an affected device and a sample project. Thank you.

Description: On iOS 27.0 (24A437) with Apple Intelligence enabled, sharing a Writing Tools result to a share extension fails as soon as the extension shows a keyboard. Steps: Safari (also Chrome, NAVER app): select a paragraph → Writing Tools → Proofread (or Rewrite / Summary). In the result panel tap Share → choose Notes (Apple) or any third-party extension whose sheet focuses a text view. In the extension's sheet, tap the text so the keyboard appears (for SLComposeServiceViewController-based extensions this happens automatically on presentation). Expected: the extension sheet stays open; the user edits and posts. Actual: about 0.3–1.0 s after the keyboard appears, the extension sheet, the share sheet and the Writing Tools panel are all dismissed. Nothing is saved. Apple Notes' own share extension shows the same behaviour when its text is tapped. Impact: no share extension can accept edits from the Writing Tools result panel; developers cannot detect the host or avoid the keyboard when the user wants to type. Device: iPhone 15 Pro (iPhone16,1), iOS 27.0 (24A437)

Hello fellow developers, I’ve been working with the CallKit framework in iOS, specifically handling incoming calls. One issue I’ve encountered is that Siri when "read caller name" is enabled announces the caller name/surname set via localizedCallerName and then reads the generic handle value (usually alphanumeric) too! Has anyone encountered a similar situation or if there’s a solution to prioritize the localizedCallerName over the generic handle value without using CXHandleType.emailAddress? Alternatively, any insights or workarounds you know would be greatly appreciated. TLDR: even when I correctly configure the localizedCallerName property, Siri persists in reading the CXHandleType.generic. The original Implementation with CXHandleType.generic: The issue arises when using CXHandleType.generic for alphanumeric IDs (or even URLs as stated by documentation https://developer.apple.com/documentation/callkit/cxhandle). Despite correctly setting the localizedCallerName, Siri continues to announce the generic handle value. Expected Behavior: Siri should read only the localizedCallerName when set and ignore the generic handle value when announcing incoming calls. Workaround: Currently, the only workaround is to use CXHandleType.emailAddress for alphanumeric IDs. However, this is not ideal since it repurposes an email-related handle type for a different purpose. Steps to Reproduce: Create a CallKit app that handles incoming calls (example app from documentation can be used too). On incoming call create CXCallUpdate object Create a CXHandle with CXHandleType.generic and an alphanumeric value (e.g., “ABC123”). Pass the CXHandle to the CXCallUpdate objects' remoteHandle. Set the localizedCallerName property of the CXCallUpdate object with a custom caller name/surname. Report the call with reportNewIncomingCallWithUUID Observe that Siri reads both the localizedCallerName and the generic handle value during call announcements. While we are here a Feature Request: Developers should be able to provide a user-friendly caller name without resorting to workarounds like using CXHandleType.emailAddress. I kindly request that Apple consider enhancing Siri’s behavior in the following ways: Allow developers to suppress the reading of generic handle values while still using the correct handle type. Introduce additional type options for call announcements that don't read the generic value. Both of the above. Thank you for your help! 🙌

CTFontManagerCreateFontRequestRunLoopSource does not receive any font requests on macOS 27, since beta 5. This API worked fine until macOS 27 beta 4, including previous macOS releases. It looks like this is caused by the App Sandbox. When the com.apple.security.app-sandbox entitlement is disabled the font request source does receive events. Report including sample project: FB24764122 let source = CTFontManagerCreateFontRequestRunLoopSource(0, { (dict, pid) in /* does not receive events when sandboxed */ } CFRunLoopAddSource(CFRunLoopGetCurrent(), source, .defaultMode) Is this a deliberate change or is this a bug in macOS 27? Is there an entitlement that can be set to enable the API in sandboxed apps? My application is distributed on the Mac App Store and as standalone app. Both are properly sandboxed for added security. Disabling the App Sandbox for this specific API would be very undesirable as users will lose all Sandbox benefits.

A macOS app that never reads or writes notes cannot update a contact that has a note property. CNSaveRequest.update() throws NSCocoaErrorDomain 134092 with NSUnderlyingException "Unhandled error (NSCocoaErrorDomain, 134092) occurred during faulting". CNContactNoteKey is never requested. I reduced it to a minimal app whose only action is toggling familyName, and confirmed the cause in both directions: Create a contact programmatically. The update succeeds. Add a note to it in Contacts.app. The identical update now fails with 134092. Set that note to an empty string. Still fails. Remove the note property entirely. The update succeeds again. Contacts imported from a vCard fail from the start, even when the vCard has no NOTE line and Contacts.app shows no note. Clearing the note property on such a contact also makes the update succeed, so I believe the import attaches the property invisibly. Ruled out: mutableObjects instead of mutableCopy, including or omitting CNContactNoteKey, unified versus non-unified fetches, and the app sandbox (an ad-hoc signed build with no sandbox fails the same way). Full Disk Access does not help. I could not test the entitlement itself: an ad-hoc signed build carrying com.apple.developer.contacts.notes is refused at launch (RBSRequestErrorDomain 5, "Launchd job spawn failed"), since it is a restricted entitlement that needs a provisioning profile. Question: is com.apple.developer.contacts.notes required to update any contact that merely has a note, even when the app never reads or writes notes? If so, what is the expected path for an app that only reorders phone numbers and email addresses? The error itself gives no hint that notes are involved. If anyone here already holds the notes entitlement: does saving succeed for you on a contact that has a note? I have a request pending, and confirming this before it is decided would help a great deal. Environment: macOS 26 (Darwin 25.x), Apple Silicon. Filed as FB23452026.
