Receiving messages from TelephonyMessagingKit
I'm currently experimenting with TelephonyMessagingKit on iOS 26 Beta 3 (in the EU). I've managed to register my example project as the default Carrier messaging app, and sending/receiving SMS inside the app also appeared to work. However, I do not see any way to receive notifications/messages while the app is not running. Is this intentional? Not being able to notify users about an incoming message would be a competitive disadvantage compared to Apple's messages app, which is why I'd expect there to be an API to do this, given the EU rules. I'd appreciate any help here. Thanks!

About Universal Links
I have been using Universal Links since January of this year. As of January, it was working fine, but when I checked its operation in August, it was no longer working properly. After investigating, I believe that the reason it is not working is because our firewall is blocking communication from AppleCDN to check for AASA files. Our firewall blocks communication from outside Japan, and Apple's IP address (17.0.0.0/8) is whitelisted. Does anyone know the hostname or IP address that is used to check AASA files? If you know, please let me know.

Fall Detection event sequencing
The sequence of events when Fall Detection is triggered is not clear from the documentation. https://developer.apple.com/forums/thread/763738 This post assumes that when a fall is detected by the watch, the standard UI ("It looks like you've taken a hard fall...") is shown, and only after this is resolved (user taps an option or times out) is an event sent to the CMFallDetectionDelegate in our app - is that correct? Is it possible instead to have our delegate be notified of a fall event immediately, and let our app's UI present options for next steps to the user?

Can FamilyControls ApplicationToken or CategoryToken expire? If yes, how to detect and handle it?
How to programmatically check if ApplicationToken or ActivityCategoryToken is expired in FamilyActivityPicker? I'm building a Screen Time-based parental control app using FamilyControls and ManagedSettings. We use FamilyActivityPicker to allow the user to select apps and categories to restrict, and we apply the shield using: store.shield.applications = .specific(selection.applicationTokens) store.shield.applicationCategories = .specific(selection.categoryTokens) Sometimes, we observe that the shield silently fails to apply — no error is thrown, but the restrictions aren't enforced. I suspect this may be due to expired or invalid tokens, possibly if the app was removed or the selection became stale. My Questions: Can ApplicationToken or ActivityCategoryToken expire or become invalid over time? If yes, is there a supported or recommended way to detect whether a token is still valid before applying it to the shield? Is comparing the current shield values (store.shield.applications and store.shield.applicationCategories) after applying them a reliable validation method? What's the best practice to handle expired tokens (e.g. re-prompt the FamilyActivityPicker, or show a fallback)? What Is the Expiration Duration of Tokens from FamilyActivityPicker? Any guidance or insight from the Screen Time/FamilyControls team would be greatly appreciated! Thank you!

WebDomain.token always returns nil - What am I doing wrong?
I'm new to the Screen Time API and trying to block custom websites, but I can't get WebDomain tokens to work. When I create a WebDomain like WebDomain(domain: "reddit.com"), the token property is always nil. I have proper authorization and the app works fine for blocking apps, but website blocking just won't work. I'm confused because I see apps like JOMO that let users type in any website domain and successfully block it using Screen Time API. They have the same 49 domain limit and only ask for Screen Time permission, so they must be using the same API I am. But somehow their WebDomain tokens work and mine don't. I've tried creating the tokens right after getting authorization and during the FamilyActivityPicker session, but still get nil. Am I missing some setup step or API call that makes WebDomain tokens valid? Any help would be really appreciated since I'm stuck on this.

There were problems encountered during the development of core spotlight.
In IOS17 and IOS18, core spotlight can only match app contents by searching for the displayName, but cannot hit the contents by using keywords. Moreover, when matching the app content by searching for the "displayName", it requires inputting four consecutive characters to achieve a match.These issues did not occur in iOS 16. What is the reason for this? Here is my code. 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: "xxx", attributeSet: attributeSet) searchableItem.expirationDate = .distantFuture CSSearchableIndex.default().indexSearchableItems([searchableItem]) { error in if let error = error { } else { } } }

Live Lookup flow stuck at /issue/token-key-for-user-token endpoint
Hi Apple engineering team, I’m trying to integrate the new Live Caller ID Lookup (PIR) on iOS using your pir-service-example code as well as a custom mock server in Vapor, but the extension never advances past the /issue/token-key-for-user-token step. I’ve tried both: 1. Official Example Cloned https://github.com/apple/pir-service-example Ran PIRService locally Confirmed that GET /.well-known/private-token-issuer-directory → 200 GET /issue/token-key-for-user-token → 200 (DER bytes, correct SPKI) No POST /issue ever fires 2. Mock Server (Vapor) Implemented all five endpoints (/config, /.well-known/private-token-issuer-directory, /issue/token-key-for-user-token, /issue, /queries) Verified with curl and openssl asn1parse that: GET /.well-known/private-token-issuer-directory Content-Type: application/private-token-issuer-directory { "issuer-request-uri":"https://…/issue", "token-keys":[…] } GET /issue/token-key-for-user-token Content-Type: application/octet-stream <DER bytes> Added Cache-Control: public, max-age=3600 on directory and SPKI Stubbed POST /issue to always return { "token": "" } Still no POST /issue request from the extension Reproduction Steps Install and enable a Live Lookup extension pointing to my server. Trigger an incoming call on device. Watch server logs—only see the two GETs, never /issue or /queries. Expected Behavior After fetching the SPKI DER, the framework should issue a POST /issue call (Privacy Pass flow) and then POST /queries. Observed Behavior Stuck in an infinite loop of: GET /.well-known/private-token-issuer-directory GET /issue/token-key-for-user-token (repeat…) No progression to the /issue or /queries endpoints. What I’ve Tried Verified JSON kebab-case and headers exactly match examples Confirmed SPKI DER is valid via openssl asn1parse Added Cache-Control headers Tested on real device, localhost url, and ngrok public URL Mocked a valid-looking token response Could you advise what additional requirement or format detail I’m missing that prevents from advancing past /issue/token-key-for-user-token? These are the main files: LiveLookupExtension.swift routes.swift service-config.json Thanks in advance!

WeatherKit JWT Auth error for SOME customer devices
We have a subscription WeatherKit app which has been on the App Store since December 2023. I am getting intermittent JWT auth failures on customer devices. In the great majority of cases, the request succeeds, but sometimes it fails, and sometimes it fails and never recovers. I’m working with a customer right now who is unable to get any weather data at all, and the logs he sends me show WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors error 2 The app uses the WeatherKit SDK (we are not using the REST API directly). We know we have the project setup as it has been working since launch, and I can verify weatherkit using security cms -D -i embedded.mobileprovision It it not a problem with the specific query, since I can get data for the dates and locations they are requesting. I can’t replicate the problem on my test devices. In case there is a rate limit issue: this app is a bit unusual and downloads an unusual amount of data at once using multiple queries in parallel using a TaskGroup. When the user creates a location, the app downloads a 10 day block of weather (7 days in the past + 3 day forecast) using WeatherService.shared.weather( for: location, including: WeatherQuery.daily( startDate: startDate, endDate: endDate ), WeatherQuery.hourly( startDate: startDate, endDate: endDate ) ) It also downloads about 2 months of daily precipitation data using multiple parallel calls to dailySummary in 10 day blocks: WeatherService.shared.dailySummary( for: location, forDaysIn: DateInterval(start: startDate, end: endDate), including: .precipitation ) In almost every case, including on my test devices, this works. But some users get WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors error 2 on every request. The two users yesterday that had this problem were both on iOS 18.5 for what that's worth, though the app supports 17.2+ Is anyone else seeing this? And can anyone suggest anything else to explore? It's obviously a terrible experience for customers who pay for the service and are unable to get any data. I did submit this info to Apple as FB18276275

[Proposal] Sense & Store – Intelligent App Suggestions from Safari (with On-Device AI)
Hello everyone, I’d like to propose Sense & Store — a seamless integration between Safari and the App Store, powered by on-device AI, designed to understand what users are reading, searching, or selecting in Safari, and suggest relevant apps that match their current context or intention. 🔍 Key Idea: “Sense” the user’s need through intelligent analysis of web content, then “Store” — offer the most relevant app, either already installed or available in the App Store. 🌟 Core Features: • AI-powered context detection directly inside Safari • Real-time app suggestions based on user intent • Smart overlays when selecting text or data (e.g., phone numbers, emails, tools) • Privacy-first: All AI runs on-device (Apple Neural Engine) • Instant App Launch or Installation via StoreKit ✅ Examples: • Reading an article on productivity? → Suggests Notion or Things. • Looking up meditation tips? → Recommends Calm or Headspace. • Selecting a phone number? → Offers CRM or spam blocker apps. • Exploring code samples? → Suggests Pythonista or developer tools. 🔒 Privacy & Performance: • 100% on-device intelligence (no data sent to servers) • Follows Apple’s privacy framework • Works with SafariKit + StoreKit + CoreML ⸻ I’m happy to provide a full prototype roadmap and technical architecture. Feedback and collaboration are welcome! Would love to hear your thoughts — especially from developers who build for Safari, App Clips, or work with CoreML. Thanks! by: Apple lover....

How to debug Quick Look Preview Extension
I'm facing the same problem as addressed in this discussion: After switching from legacy QLGenerators to Preview extensions on macOS I cannot debug the extensions' code in Xcode, anymore: I launch the app with the embedded appex from Xcode in debug mode. When trying to attach to the appex process the following error is reported: Code: 6 Failure Reason: Ensure “AppName Preview” is not already running, and matthias has permission to debug it. User Info: {... } System Information macOS Version 15.4.1 (Build 24E263) Xcode 16.3 (23785) (Build 16E140) Timestamp: 2025-05-12T14:07:14+02:00 I'm using a standard user account (no admin) and might miss some obvious steps. Can someone detail the steps to debug a Preview (or Thumbnail) extension with Xcode 16? For legacy Quick Look plugins I was using "qlmanage", but that's not working on extensions. All the best, Matthias P.S.: Pardon me re-posting my reply as a separate thread, to increase visibility, but I'm quite desperate and couldn't find any solution on the web...

Weird DateFormatter behavior
I am seeing a weird behavior of the date formatter (Full code is below). When run, this will give the following output: 57: 1 month, 3 weeks, 5 days 58: 1 month, 3 weeks, 6 days 59: 2 months 60: 2 months, 1 day 61: 2 months 62: 2 months, 1 day 63: 2 months, 2 days So both 59 days and 61 days are 2 months, and both 60 and 62 days are 2 months and 1 day. This of course is especially weird because this means, 2 months also comes after 2 months and a day. Can someone explain to me what is going on here? import Foundation let formatter = DateComponentsFormatter() formatter.unitsStyle = .full let calendar = Calendar(identifier: .gregorian) let today = calendar.date(from: DateComponents(year: 2025, month: 7, day: 26))! for day in 57...63 { let startDate = calendar.date(byAdding: .day, value: -day, to: today)! let components = calendar.dateComponents([.day, .weekOfMonth, .month,. year], from: startDate, to: today) let result = formatter.string(from: components)! print ("\(String(format: "%3d", day)): \(result)") }

Worried that Rosetta 2 will eventually be removed - I need some reassurance
I am worried that Rosetta 2 will eventually be removed. I rely on it to run x86-64 Docker containers as well as Windows games through the Game Porting Toolkit. I also use CrossOver very often, which relies on Rosetta. I also use an old version of MuseScore that needs it, and every now and then, I download a legacy Intel Mac app. Thus, I'm worried that Apple will no longer offer it for download in future macOS versions. Are there any plans to remove Rosetta? Since Rosetta is only installed on demand, I have a slight bit of reassurance that it might be offered for download indefinitely, since most casual users naturally won't install it in the future as most general consumer apps are compiled natively for ARM, and the on-demand install cuts down on the bloat included with macOS by default. I hope Rosetta could be offered indefinitely, since many pro-users and gamers rely on it very often, even 10 years from now when Intel Macs are completely unsupported. If Rosetta is removed, I might have to switch back to Windows for many tasks, so I really hope for the continued offering of Rosetta.

encountering a console warning when accessing NSUserDefaults within the willFinishLaunchingWithOptions method. However, it appears that all the key values are loading correctly despite the warning.

Apps remain blocked after being unselected
Hi everyone, We're using the react-native-device-activity package to implement app blocking via Apple's Screen Time API. The blocking functionality works well: when the user selects apps and taps "Done," those apps get blocked as expected. However, we're facing an issue with unblocking apps that the user later unselects. Even after the user unchecks some apps and taps "Done" again, those previously selected (now unselected) apps remain blocked and still show the shield.

Finder shows warning "Apple could not verify file is free of malware" when setting my app as "Always open with"
A user of my AppKit, document-based app brought to my attention that when setting it as the default app to open a certain file with extension .md (by choosing in the Finder "File &gt; Open With &gt; Other", then selecting my app and enabling "Always open with"), trying to open it with a double-click displays the warning "Apple could not verify [file] is free of malware that may harm your mac or compromise your privacy". This is what happens for me: When keeping the default app for a .md file (Xcode in my case), the file opens just fine. When choosing my app in the "File &gt; Open With" menu, the file opens just fine in my app. But when setting my app as the default app (see above), the warning is displayed. From that moment on, choosing my app in the "File &gt; Open With" menu doesn't work anymore. Selecting Xcode doesn't work either. Only setting Xcode again as the default app allows me to open it in Xcode, but my app still isn't allowed to open it. Is this a macOS issue, or can I do anything in my app to prevent it? Where should I start looking for the issue in my code?

WeatherKit JWT Auth error for SOME customer devices
We have a subscription WeatherKit app which has been on the App Store since December 2023. I am getting intermittent JWT auth failures on customer devices. In the great majority of cases, the request succeeds, but sometimes it fails, and sometimes it fails and never recovers. I’m working with a customer right now who is unable to get any weather data at all, and the logs he sends me show WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors error 2 The app uses the WeatherKit SDK (we are not using the REST API directly). We know we have the project setup as it has been working since launch, and I can verify weatherkit using security cms -D -i embedded.mobileprovision It it not a problem with the specific query, since I can get data for the dates and locations they are requesting. I can’t replicate the problem on my test devices. In case there is a rate limit issue: this app is a bit unusual and downloads an unusual amount of data at once using multiple queries in parallel using a TaskGroup. When the user creates a location, the app downloads a 10 day block of weather (7 days in the past + 3 day forecast) using WeatherService.shared.weather( for: location, including: WeatherQuery.daily( startDate: startDate, endDate: endDate ), WeatherQuery.hourly( startDate: startDate, endDate: endDate ) ) It also downloads about 2 months of daily precipitation data using multiple parallel calls to dailySummary in 10 day blocks: WeatherService.shared.dailySummary( for: location, forDaysIn: DateInterval(start: startDate, end: endDate), including: .precipitation ) In almost every case, including on my test devices, this works. But some users get WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors error 2 on every request. The two users yesterday that had this problem were both on iOS 18.5 for what that's worth, though the app supports 17.2+ Is anyone else seeing this? And can anyone suggest anything else to explore? It's obviously a terrible experience for customers who pay for the service and are unable to get any data. I did submit this info to Apple as FB18276275

User Info: {... } System Information macOS Version 15.4.1 (Build 24E263) Xcode 16.3 (23785) (Build 16E140) Timestamp: 2025-05-12T14:07:14+02:00 I'm using a standard user account (no admin) and might miss some obvious steps. Can someone detail the steps to debug a Preview (or Thumbnail) extension with Xcode 16? For legacy Quick Look plugins I was using "qlmanage", but that's not working on extensions. All the best, Matthias P.S.: Pardon me re-posting my reply as a separate thread, to increase visibility, but I'm quite desperate and couldn't find any solution on the web...

Weird DateFormatter behavior
I am seeing a weird behavior of the date formatter (Full code is below). When run, this will give the following output: 57: 1 month, 3 weeks, 5 days 58: 1 month, 3 weeks, 6 days 59: 2 months 60: 2 months, 1 day 61: 2 months 62: 2 months, 1 day 63: 2 months, 2 days So both 59 days and 61 days are 2 months, and both 60 and 62 days are 2 months and 1 day. This of course is especially weird because this means, 2 months also comes after 2 months and a day. Can someone explain to me what is going on here? import Foundation let formatter = DateComponentsFormatter() formatter.unitsStyle = .full let calendar = Calendar(identifier: .gregorian) let today = calendar.date(from: DateComponents(year: 2025, month: 7, day: 26))! for day in 57...63 { let startDate = calendar.date(byAdding: .day, value: -day, to: today)! let components = calendar.dateComponents([.day, .weekOfMonth, .month,. year], from: startDate, to: today) let result = formatter.string(from: components)! print ("\(String(format: "%3d", day)): \(result)") }

Worried that Rosetta 2 will eventually be removed - I need some reassurance
I am worried that Rosetta 2 will eventually be removed. I rely on it to run x86-64 Docker containers as well as Windows games through the Game Porting Toolkit. I also use CrossOver very often, which relies on Rosetta. I also use an old version of MuseScore that needs it, and every now and then, I download a legacy Intel Mac app. Thus, I'm worried that Apple will no longer offer it for download in future macOS versions. Are there any plans to remove Rosetta? Since Rosetta is only installed on demand, I have a slight bit of reassurance that it might be offered for download indefinitely, since most casual users naturally won't install it in the future as most general consumer apps are compiled natively for ARM, and the on-demand install cuts down on the bloat included with macOS by default. I hope Rosetta could be offered indefinitely, since many pro-users and gamers rely on it very often, even 10 years from now when Intel Macs are completely unsupported. If Rosetta is removed, I might have to switch back to Windows for many tasks, so I really hope for the continued offering of Rosetta.

encountering a console warning when accessing NSUserDefaults within the willFinishLaunchingWithOptions method. However, it appears that all the key values are loading correctly despite the warning.
App initiates a App group based UserDefaults within the willFinishLaunchingWithOptions method and the same reference are used throughout the app life cycle + (NSUserDefaults *)appGroupUserDefaults { if (_appGroupUserDefaults == nil) { NSString *appGroupIdentifier = [NSString stringWithFormat:@"group.%@",[[NSBundle mainBundle] bundleIdentifier]]; NSUserDefaults *groupDefaults = [[NSUserDefaults standardUserDefaults] initWithSuiteName:appGroupIdentifier]; if(groupDefaults != nil) { NSLog(@"[DB_ENCRYPTION] appGroupUserDefaults initialised"); _appGroupUserDefaults = groupDefaults; } else { NSLog(@"<ALA_ERROR>: [CCF-OS] [DB_ENCRYPTION] %s Unable to create NSUSerDefaults with groupIdentifier", __func__); _appGroupUserDefaults = [NSUserDefaults standardUserDefaults]; } } return _appGroupUserDefaults; } Doesn't have any issues on accessing the values but seen the below console error: Couldn't read values in CFPrefsPlistSource<0x103eedb00> (Domain: group.com.kodiak.InstaPoC, User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd Does it require any action here ?

Apps remain blocked after being unselected
Hi everyone, We're using the react-native-device-activity package to implement app blocking via Apple's Screen Time API. The blocking functionality works well: when the user selects apps and taps "Done," those apps get blocked as expected. However, we're facing an issue with unblocking apps that the user later unselects. Even after the user unchecks some apps and taps "Done" again, those previously selected (now unselected) apps remain blocked and still show the shield.

Finder shows warning "Apple could not verify file is free of malware" when setting my app as "Always open with"
A user of my AppKit, document-based app brought to my attention that when setting it as the default app to open a certain file with extension .md (by choosing in the Finder "File &gt; Open With &gt; Other", then selecting my app and enabling "Always open with"), trying to open it with a double-click displays the warning "Apple could not verify [file] is free of malware that may harm your mac or compromise your privacy". This is what happens for me: When keeping the default app for a .md file (Xcode in my case), the file opens just fine. When choosing my app in the "File &gt; Open With" menu, the file opens just fine in my app. But when setting my app as the default app (see above), the warning is displayed. From that moment on, choosing my app in the "File &gt; Open With" menu doesn't work anymore. Selecting Xcode doesn't work either. Only setting Xcode again as the default app allows me to open it in Xcode, but my app still isn't allowed to open it. Is this a macOS issue, or can I do anything in my app to prevent it? Where should I start looking for the issue in my code?
