Spotlight search by keywords setuped in NSUserActivity doesn't work
Hey there! I faced issue in iOS 18 and newer when Spotlight search doesn't show my App in results. In older versions it works. Here is my code: func configureUserActivitity(with id: String, keywords: [String]) { let activity = NSUserActivity(activityType: id) activity.contentAttributeSet = self.defaultAttributeSet activity.isEligibleForSearch = true activity.keywords = Set(keywords) activity.becomeCurrent() self.userActivity = activity } I didn't find any reasons why it doesn't work now. Maybe I should report a bug?

For receiving audio in PushtoTalk, channelManager(_:didActivate:) not called when app receives first push after backgrounding
I'm implementing the PushToTalk framework and have encountered an issue where channelManager(_:didActivate:) is not called under specific circumstances. What works: App is in foreground, receives PTT push → didActivate is called ✅ App receives audio in foreground, then is backgrounded → subsequent pushes trigger didActivate ✅ What doesn't work: App is launched, user joins channel, then immediately backgrounds PTT push arrives while app is backgrounded incomingPushResult is called, I return .activeRemoteParticipant(participant) The system UI shows the speaker name correctly However, didActivate is never called Audio data arrives via WebSocket but cannot be played (no audio session) Setup: Channel joined successfully before backgrounding UIBackgroundModes includes push-to-talk No manual audio session activation (setActive) anywhere in my code AVAudioEngine setup only happens inside didActivate delegate method Issue persists even after channel restoration via channelDescriptor(restoredChannelUUID:) Question: Is this expected behavior or a bug? If expected, what's the correct approach to handle incoming PTT audio when the app is backgrounded and hasn't received audio while in the foreground yet?

Phonetic vs Pronunciation contacts fields and Siri
The contacts app has fields for Phonetic and Pronunciation. My app adds phonetic data to the phonetic field to help Siri better understand contacts stored in Greek, Cyrillic, or Georgian. However, using the phonetic field causes the sorting order of contacts to be messed up. For example, Greek B (beta) is represented as a phonetic sound of V, resulting in a completely incorrect sorting order. The pronunciation field doesn’t seem to affect the sorting order, but I’m not sure what it does or should do. My questions are: Do we understand the difference between phonetic and pronunciation, and how Siri actively uses them? If the phonetic field is the correct one to use, how can we raise a feature request with Apple to add an option to sort contacts based on phonetic fields or not? Here’s a test you can try: Create a new contact with the following details: First name: test Last name: test Phonetic first name: Billy Phonetic last name: Idol Ask Siri to show the contact Billy Idol. It will return the “test test” contact. Switch from the phonetic to the pronunciation fields. Now, Siri won’t find Billy Idol.

Interactive Widget: unable to reload timeline from AppIntent
My app features two kinds of widgets, let's call them kind A and kind B. I have both A and B widgets on my Home Screen. When I tap the button on widget A (associated with App Intent), I expect widget B to also reload. However, if you call WidgetCenter.shared.reloadAllTimelines() inside the perform() method of the AppIntent, the timeline of widget B does not reload immediately. This issue only occurs on a physical device and is not consistently reproducible. On a simulator, however, widget B reloads as expected. FB13152293

Universal Link Not Working – Apple Request Blocked by Firewall Due to Geographic Restriction
Hello, I’m encountering an issue with Universal Links in my iOS app. After some investigation, I found that the root cause seems to be that Apple’s request through there CDN server to access the .well-known/apple-app-site-association file is blocked by our firewall, which enforces geographic access restrictions as part of our security policy. Because of this restriction, Apple’s validation or link verification requests are being denied, and the Universal Links are not working as expected. I’d like to get some guidance from the community or Apple engineers on the following: 1. Does Apple provide an official list of IP ranges or domains that need to be allowed through the firewall for Universal Link validation? 2. Are there alternative methods to handle Universal Link verification in environments with geographic restrictions? 3. Would whitelisting specific Apple services or endpoints be a recommended or safe solution? Any input or recommendations would be greatly appreciated. Environment Details: • iOS app using Universal Links • Server protected by a firewall with regional restrictions • AASA file hosted correctly and accessible via browser Thanks in advance for your help and insights.

Translation framework error.
Hello everyone. I use Translation Framework in my application. During development everything was fine, Translation framework worked well, but after two or three days of using the production version (that was published in AppStore and available for others also!) - my application stopped working. Translation framework gives errors: Error sending 1 paragraphs Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Failed to translate input 0; returning error: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Received unbridged NSError to API, converting to .internalError: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Once again - it worked when I developed it, it was released on the AppStore, and suddenly it stopped working!

iOS fails to fetch AASA file for IDNs
Subject: iOS Fails to Fetch AASA File for Internationalized Domain Names (IDN) in Unicode or Punycode Format Dear Apple Developer Relations Team And Community Members, We are reporting a critical bug in the iOS Associated Domains feature that prevents Universal Links from working for apps using Internationalized Domain Names (IDN). Problem Description: The iOS operating system does not attempt to download the apple-app-site-association (AASA) file for domains containing non-ASCII characters (e.g., diacritics, Cyrillic). This failure occurs regardless of whether the domain is specified in the app's entitlements in its human-readable Unicode format (e.g., montréal.ca) or its encoded Punycode format (e.g., xn--montral-fya.ca, xn--e1afka0abm4b.xn--p1ai). Without fetching and validating this file, Universal Links are not activated, and the system fails to establish a connection between the website and our app. Steps to Reproduce: Create an app with the Associated Domains entitlement enabled. Add an IDN to the entitlement. We tested both formats: Format A (Unicode): applinks://montréal.ca Format B (Punycode): applinks://xn--montral-fya.ca Host a valid AASA file on our server at the correct, accessible well-known URLs for both domain representations: For montréal.ca: https://montréal.ca/.well-known/apple-app-site-association and https://xn--montral-fya.ca/.well-known/apple-app-site-association Install the app on a device running the latest iOS version. Monitor network traffic using a tool like Charles Proxy. Observed Result: No HTTP GET request is made to any of the AASA URLs for the domains montréal.ca (in either Unicode or Punycode format) upon app installation. The system does not initiate the domain validation process. In contrast, for a standard ASCII domain (e.g., applinks://example.com), the AASA fetch is triggered immediately and is observed in the network log. Expected Result: iOS should correctly resolve the Internationalized Domain Name (whether specified in Unicode or Punycode format in the entitlement) and perform an HTTP GET request to fetch the AASA file from the /.well-known path, identical to its behavior for ASCII domains. Evidence & Configuration: Our server is configured correctly: SSL certificates are valid, the AASA file is served with the correct application/json MIME type, and is directly accessible via a browser or curl. The AASA file's syntax has been validated and is correct. The issue is reproducible on the latest versions of iOS. Impact: This bug blocks a core platform feature for millions of users in regions that use non-Latin scripts (e.g., France, Russia, China, Arab states). It makes it impossible to use Universal Links with our primary domains, severely degrading the user experience and forcing us to seek suboptimal workarounds like registering separate ASCII domains. Request: We kindly request that you investigate and log this issue as a bug in iOS and forward it to the appropriate engineering team for a fix in an upcoming update. We are prepared to provide any additional information, demo projects, or server access to assist in diagnostics. Thank you for your attention to this serious matter.

WeatherKit fails on AppStore
Hello, After being in the AppStore for more than a year with the app working perfectly, yesterday I started seeing that WeatherKit requests failed with Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Encountered an error when fetching weather data subset; location=<+41.40217108,+2.20023642> +/- 0.00m (speed -1.00 mps / course -1.00) @ 13/12/25, 12:20:35 Central European Standard Time, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" I checked on developer.apple.com and we still have everything turned on and No changes were made from an already deployed app; and we pay 200$ a month for WeatherKit, this is unacceptable since it's not the first time WeatherKit randomly decides to stop working. More fun facts: the widget works fine...

Critical Technical Issue: App Update Rendering iPhones Inoperative on iOS 16 Versions
We appreciate your suggestion to use the Apple Developer Forums. However, we must respectfully request further escalation of this issue beyond the forums for several critical reasons: Severity and Scope: This is not a general development discussion topic. We are facing a massive, reproducible performance issue on iOS 16 that renders devices unresponsive, requiring factory resets or DFU restores. This goes far beyond typical app bugs and points to a potential systemic issue in the OS's image handling. Insufficiency of Forum Support: While the forums are a valuable resource for community advice, they cannot provide the official, in-depth technical diagnosis from Apple engineers that this situation demands. Our users' devices are being bricked by an app update that passed App Review, and we require clarity on the root cause to prevent further damage and restore user trust. Code-Level Support Eligibility: As members of the Apple Developer Program, we believe our issue falls under the purview of Code-Level Support, as described on the Apple Developer website 9. Our problem involves "building or running software" and requires expertise in Apple's frameworks and hardware-level image rendering APIs. We request that our case be forwarded to that specialized team. To reiterate the core problem: Our update introduced 1024x1026 JPEG assets into the Asset Catalog. On iOS 16, this causes severe overheating, freezing, and device unresponsiveness. Replacing them with PNGs completely resolves the issue. This suggests a potentially serious regression in iOS 16's JPEG decoding or memory management pipeline. We prepared to provide a sample project that demonstrates the issue if required. Our case number is 102678393572. We urgently need to understand why this happens at the OS level to ensure our app is safe and to contribute to the stability of the iOS platform. Please escalate this case to the appropriate technical team for a detailed investigation. Sincerely,

Apple CDN connection error after changing server ip version to v6
The universal links for my apps stopped working. The server where the AASA files where hosted worked on IPV4 exclusively, a few days ago i changed the configuration to IPV6 only. I´ve created new IPV6 entries, renewed all certifactes and deleted all IPV4 entries for the domains. All seemed fine, but at Saturday I realized that my universal links stopped working for new user. What i´ve done to find the issue: Example domain that was used for debugging: "https://developffw.burns.fun" I´ve verified the AASA file is hosted properly by using different browsers and Postman to retrieve it. The file can be accessed and the certificates look fine. Output of curl -v https://developffw.burns.fun/.well-known/apple-app-site-association * Host developffw.burns.fun:443 was resolved. * IPv6: 2a01:4f8:13b:340a::2 * IPv4: (none) * Trying [2a01:4f8:13b:340a::2]:443... * schannel: disabled automatic use of client certificate * ALPN: curl offers http/1.1 * ALPN: server accepted http/1.1 * Established connection to developffw.burns.fun (2a01:4f8:13b:340a::2 port 443) from 2a00:79c0:65c:8b00:80ee:175b:3e2a:1e7d port 61014 * using HTTP/1.x > GET /.well-known/apple-app-site-association HTTP/1.1 > Host: developffw.burns.fun > User-Agent: curl/8.16.0 > Accept: */* > * Request completely sent off < HTTP/1.1 200 OK < Server: nginx/1.22.1 < Date: Mon, 15 Dec 2025 11:34:22 GMT < Content-Type: application/octet-stream < Content-Length: 329 < Last-Modified: Sat, 21 Dec 2024 08:53:11 GMT < Connection: keep-alive < ETag: "676681f7-149" < Accept-Ranges: bytes < { "applinks": { "details": [ { "appIDs": [ "6LN7G8JEA5.burns.FFW-Manager-SwiftUI.Debug"], "components": [ { "/": "/onboard", "?": { "id": "*"}, "?": { "name": "*"}, "?": { "token": "*" } } ] } ] } } * Connection #0 to host developffw.burns.fun:443 left intact I took a look at the headers from the Apple CDN network response. These indicate some sort of connection error. The response code is 404 Response headers: Apple-Failure-Details: {"cause":"dial tcp [2a01:4f8:13b:340a::2]:443: connect: network is unreachable"} Apple-Failure-Reason: SWCERR00305 Network error Apple-From: https://betaffw.burns.fun/.well-known/apple-app-site-association Apple-Try-Direct: false Via: https/1.1 defra2-vp-vst-003.ts.apple.com (acdn/268.16305), https/1.1 defra2-vp-vfe-004.ts.apple.com (acdn/268.16305), http/1.1 defra2-xdc-mx-028.ts.apple.com (acdn/3.16363), https/1.1 defra1-edge-fx-021.ts.apple.com (acdn/3.16363) X-Cache: hit-stale, miss, hit-fresh, miss CDNUUID: 4321f35e-b73b-4031-a054-7c63af69e126-712221049 Took a look at the log files of the server. I can´t find any entry from the Apple servers neither in the default logs nor in the error log entries. The curl attempts are logged with response code 200. I´ve tried sudo swcutil dl -d https://developffw.burns.fun/onboard in the Terminal on my MAC. Output: The operation couldn´t be completed. (SWCErrorDomain error 8.) This indicates to me threre is an issue for the Apple servers accessing my server. But I don´t know what could be the reason. There is no firewall configuration that could block the requests. And there has been no change at all besides the IPV4 / IPV6 protocol change. This issue is the same for all the domain listed on this server. I´v even created a new app for this purpose and created a new AASA entry and associated link. Same issue. I´m pretty much lost here. Everything looks fine from my side. Google assetlinks.json seem to work fine. I would really appreciate some help on how to solve this, i´m at my wits end.

Getting ShinyTV Example to Work
I have downloaded the ShinyTV example to test simplified sign-in on tvOS since it is not working in my own app, and I am having the same issue there. After assigning my team to the sample app, the bundle ID updates with my team id. I copy the bundle ID into a file entitled "apple-app-site-association" with this format: { "webcredentials": { "apps": [ "{MyTeamID}.com.example.apple-samplecode.ShinyTV{MyTeamID}" ] } } I upload the file to my personal site, ensuring that the content type is application/json. I adjust the Associated Domain entitlement to: webcredentials:*.{personal-site.com}?mode=developer using the alternate mode to force it to load from my site, not the CDN. When I run the build on tvOS, and click the Sign In button, it fails with these errors: Failed to start session: Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 "Failed to prepare authorization requests" UserInfo={NSMultipleUnderlyingErrorsKey=( "Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 \"Missing associated web credentials domains\" UserInfo={NSLocalizedDescription=Missing associated web credentials domains}" ), NSLocalizedDescription=Failed to prepare authorization requests} Session failed: Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 "Failed to prepare authorization requests" UserInfo={NSMultipleUnderlyingErrorsKey=( "Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 \"Missing associated web credentials domains\" UserInfo={NSLocalizedDescription=Missing associated web credentials domains}" ), NSLocalizedDescription=Failed to prepare authorization requests} ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "(null)" UserInfo={NSMultipleUnderlyingErrorsKey=( "Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 \"(null)\"" )} Failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "Failed to prepare authorization requests" UserInfo={NSMultipleUnderlyingErrorsKey=( "Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 \"Missing associated web credentials domains\" UserInfo={NSLocalizedDescription=Missing associated web credentials domains}" ), NSLocalizedDescription=Failed to prepare authorization requests} What am I missing here?

Can a Live Caller ID server supply live data or must it be static?
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?

JWT Token Errors
I have an app using weatherkit and its currently live and up on the app store, recently I had some users report to me that they had been receiving errors loading weather data, I had error handling built in and it reported an issue with apples authentication server Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" I have not come across this during the development lifecycle of my project, there where no codebase changes, it just stopped functioning. The app entitlements are valid and correct, Weatherkit is enabled in both xcode and across my Certs, identifiers and profiles. I was not experiencing this issue until I reinstalled the app from the app store completly by first removing it and then re-installing fresh. Hard reboots do not help and I do not want to start suggesting to my users to factory reset their devices. We are using WeatherKit in both our main app and widget, relying entirely on Apple’s framework for authentication and token management. We do not generate or inject our own JWT tokens; all token handling is managed by WeatherKit. We have implemented a debug menu with the following actions: Clear WeatherKit JWT tokens from the keychain Clear all related UserDefaults key Clear all app group data and all UserDefaults. Perform a “nuclear” cache clear (removes all app data, keychain, and cached files). We log all WeatherKit fetch attempts and failures, including authentication errors, both in the app and widget and get nothing but code 2. We have attempted all of the above steps, but continue to experience issues with WeatherKit JWT authentication We would appreciate any guidance or insight into what else could be causing persistent WeatherKit JWT/authentication issues, or if there are any additional steps we should try. P.S. - Tested and experiencing the same issues on an iPhone 15 Pro Max and iPhone 15 The Pro Max is on the iOS 26 Beta // and the 15 is on the latest iOS 18

However, the options for switching users without fully logging out are nowhere to be found. The topic is still included in macOS Help and is shown when searching for “fast” in System Settings, however, the option is hidden/missing in the pref pane when selected.

Is it possible for a Live Caller ID server to specify different datasets?
In the documentation for the example Live Caller ID server (https://swiftpackageindex.com/apple/live-caller-id-lookup-example/main/documentation/pirservice/testinginstructions) there is an example service-config.json. file shown (without thorough documentation). That config file, and the whole of the instructions, center around there being two datasets of numbers: block and identity. My question is - is it possible for more than one dataset to be specified i.e. for block1 and block2 to be specified? The use case for this would be - suppose the Live Caller ID server has a set of numbers it has identified as being nuisance callers and so it lists these in the block section. However user A might want all these nuisance callers to be blocked but user B does not. Therefore the Live Caller ID extension on the handset would need to use a different dataset on the server so that user A's calls from a set of numbers is blocked, but user B's are not. Note that I'm not suggesting that the Caller ID server should be capable of storing individual user's preferences. All that would be required would be two data sets: one where blocked content is none and and one where blocked content is some. Then a user/app could switch between them as indicated by the user. Is that possible? If the database structure and service-config.json etc. is not configured to permit that, then could two different servers be set up to achieve this instead? i.e. so the server url specified in the app's extension can be set at run time and not at compile time?
