Hi Apple Developer, I’m working on a message-filtering application and reviewing Apple's documentation on message filtering. The documentation clearly states that MMS messages can be filtered. (https://developer.apple.com/documentation/identitylookup/sms-and-mms-message-filtering) When we refer to MMS, it includes images, short videos, and other supported multimedia formats. However, the ILMessageFilterQueryRequest only provides the message body as a String, meaning we can access text and links but not images or other media files. Could you please confirm whether Apple allows third-party applications to access multimedia content sent from unknown numbers? Looking forward to your quick response. Thanks, Rijul Singhal

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! Jose Luiz Horta Barbosa Maurity Cruz - Apple lover...

My ASA file is located here https://staging.docyt.com/apple-appsite-association It downloads fine. It does not have .json extension and neither does it reside inside the ./well-known folder. Should it work? Because opening the link https://staging.docyt.com/reset-password is not opening the app installed via TestFlight . Installing via XCode however works fine. Please help

I have prepared a NSSpellServer spelling and grammar checker for Slovenian proofing in macOS. My proofing service gets used when I explicitly set keyboard spelling language to "Slovenian (Besana)" (my proofing tool). When I set keyboard language to Automatic by Language, system does the language detection. Since it has limited support for Slovenian language, it doesn't recognize the text as Slovenian and never asks my proofing service to check the spelling. It does consult my proofing service for spelling suggestions and when it does, I see the language parameter there is set to anything but Slovenian. Is it possible to install own language detector to macOS? Or, place some language dictionary files somewhere, the system could use to extend language detection to new languages?

is there documentation where we can find details for historical parameters / limitations - so far i've found that the days limit on single API calls days limit is 7. Any other similar specs would be good to have

I am working on a Flutter application which is use solely to collect data from a bluetooth low energy (BLE) peripheral and then upload the data to our cloud. The application runs in the background 99% of the time after the initial login and BLE pairing which is causing us some issues. After the Application is backgrounded it would work for a day to 2 days and then stop working. (What I mean with working is to download data from the BLE peripheral and then upload the data to our cloud). Once the data syncing has stopped it would take up to 12 hours until data starts flowing again. I have read in a couple of places that iOS implements some sort of "budget/heuristics" when the application is running in the background to keep track of the application and when this "budget" is used up iOS will stop servicing the application until iOS decides that the application can run in the background again. My question, is it possible via a enablement or some other mechanism to prevent iOS from blocking our application from running in the background to enable 24/7 periodic data uploads every 30 minutes. We have implemented the following so far; The data sync process is triggered from the BLE peripheral using a notification. This notification is sent every 30 minutes. Each sync duration is currently 24 seconds on average, we are working on reducing this to below 10 seconds. We implemented State Restoration to assist iOS in starting the application more efficiently. We are considering using Silent Push Notifications from the Cloud to wake up the application when data hasn't synced in 6 hours. Any assistance would be high appreciated.

where can we find documentation on the following fields included in payloads? They're not listed alongside the other fields in the documentation linked below: https://developer.apple.com/documentation/weatherkitrestapi/hourweatherconditions precipitationIntensity snowfallAmount Or if we can get the data type, unit used, and description here that would be great

Hello everyone, I would like to know if there is any way for an iOS app to automatically access a user’s total Screen Time (for example, daily or weekly usage) and then share this with friends so they can compare results, like in a “Screen Time battle”? Thanks you very much for you help!

Hello Having trouble getting associated domain to work in our project. It was working when we used Branch, but our company wants to host the domain ourselves. This is a multi-scheme project, using .xcconfig files to define the correct entitlement per Build. The relevant entitlement file has: com.apple.developer.associated-domains applinks:bm.ddcas.ai in the ....{other irrelevant test associated domains....} The project Team and App ID are taken from the Identifiers screen where the Identifier capabilities has 'associated domains' ticked on. I've also checked elsewhere on AppleDeveloper/Connect to be sure. When we used Branch with domain key app links: bmstores.app.link this worked fine. With https://bm.ddcas.ai (our own host) which is publicly available and has an aasa file in both the main directory and /.well-known, typing this in safari or anything just doesn't attempt to link to the App. The iPhone is in developer mode, and using the developer menu associated domains diagnostic tool, typing https://bm.ddcas.ai results in the diagnostic saying 'The url is a Universal Link for the app with identifier **********.***etc (the app is installed on real iPhone 12, iOS 18.6.2 and my Xcode is 16.4) However, it just doesn't work if we type in https://bm.ddcas.ai and results in a Safari message of '400 not found' and the 'nginx' shows. We have read innumerable Apple Dev posts and StackOverflow posts, as well as several step by step 'how to's' online but this just isn't working. The aasa file is at https://bm.ddcas.ai/apple-app-site-association and is setup as follows: { "applinks": { "apps": [], "details": [ { "appID": "{my Team ID}.{my App ID}", "paths": [ "*" ], "components": [ { "/": "/verification", "?": { "verification_code": "[A-Za-z0-9]{6}" }, "comment": "Matches verification code path" } ] } ] } } Our Server guys say the website (bm.ddcas.ai) is public and hosted, it just doesn't have a /verification path as they say it should redirect before reaching that. Also, our Android redirect works using this site, so this appears to be something specific Apple code is looking for. What, please, are we likely to be missing as it does not seem obvious from the Apple documentation or any of the resources I have checked online. Normally we can figure anything out, but getting nowhere here so the help is appreciated.

I want to monitor again from the bellow function of DeviceActivityMonitorExtension. I have the function of startMonitoring like this. override func eventDidReachThreshold(_ event: DeviceActivityEvent.Name, activity: DeviceActivityName) { super.eventDidReachThreshold(event, activity: activity) startMonitoring() } public func startMonitoring() { let startTime = DateComponents(hour: 0, minute: 0, second: 0) let endTime = DateComponents(hour: 23, minute: 59, second: 59)//DateComponents(hour: 11, minute: 0, second: 0)// let schedule = DeviceActivitySchedule( intervalStart: startTime,//DateComponents(hour: 0, minute: 0, second: 0), intervalEnd: endTime, repeats: true //warningTime: DateComponents(minute:1) ) let selection: FamilyActivitySelection = savedSelection() ?? FamilyActivitySelection() let center = DeviceActivityCenter() let selections = self.savedSelection() ?? FamilyActivitySelection() let applications = selections.applicationTokens let categories = selections.categoryTokens let webCategories = selections.webDomainTokens let store = ManagedSettingsStore() store.shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.specific(categories, except: Set()) store.shield.applications = applications store.shield.webDomains = webCategories let scheduleHard = DeviceActivitySchedule( intervalStart: startTime,//DateComponents(hour: 0, minute: 0, second: 0), intervalEnd: endTime, repeats: true //warningTime: DateComponents(minute:1) ) let event = DeviceActivityEvent( applications: selection.applicationTokens, categories: selection.categoryTokens, webDomains: selection.webDomainTokens, threshold: DateComponents(minute: 0)//timeLimitToUseApp i.e for 15 mins ) do { try center.startMonitoring( .weekend, during: scheduleHard, events: [ .weekend: event, ] ) print("ScreenTime Monitoring Started") } catch let error { print(error.localizedDescription) } } Please provide us with a solution about starting monitoring from DeviceActivityMonitoringExtension's eventDidReachThreshold function or if there is any other way.

Hi, after updating to iOS 26 I'm encountering an issue where the FamilyActivityPicker no longer opens. No errors are shown in the console, it just never shows up. It works fine pre iOS 26. I've never had any issues with the picker showing up until iOS 26. My latest update was rejected because of this issue, but I've changed nothing in the code. Is anyone else experiencing this?

We have an application WAVE PTT(Push to talk) and Application is in foreground state, When a user receives a cellular call and it is in the "ringing" state and application receives a VoIP APNS(video call) which is reported to CallKit. User rejects the Cellular call from CallKit UI, application Video call is also getting rejected (separate feedback - 19017978) and Here the issue is observed that an Application moved to background(OS26 beta 9). Issue is not observed in iOS 18 and older versions. Frequency : 1 out of 3. Please refer the sysdiagnose logs in below reported feedback ID.

Hello, currently working on messenger with audio/video calls feature. Have found strange behavior, on some devices after accepting call via Lock Screen video button appears to be disabled. Tested on wwdc Speakerbox sample, same code iPhone 15 Pro (iOS 17.4.1) - video button disabled iPhone 14 (iOS 17.6.1) - video button active Here is my, configuration with supportVideo activated static let providerConfiguration: CXProviderConfiguration = { let configuration = CXProviderConfiguration() configuration.supportsVideo = true configuration.maximumCallGroups = 1 configuration.maximumCallsPerCallGroup = 1 configuration.supportedHandleTypes = [.generic] return configuration }() What can be the reason of this behavior? Thanks

After reading Apple documentation (FamilyControls, DeviceActivity, ManagedSettings, ManagedSettingsUI, ScreenTime) and testing the API, I do not find a way to get the child's device apps on the parent device in order to block them or disable them for a certain time. Is there a way of doing it? Or can it only be done locally on the child device?

Currenty, I'm developing a blocking and call identity call. In iOS 18, everything works fine, I can show log to debug inside my Callkit extensions But when my app run in iOS 26, I cant even turn on my caller id extension, I'm not able to debug because I dont see any log from my extensions.

I am working on enabling app clip experience for one of our products, where App X would use default appclip url of App Y to launch an experiences using UIApplication.shared.open(defaultAppclipUrl). Im successfully able to build and submit to appstore by testing via local expereince, but later noticed a strange behaviour in production without local expereince setup, where tapping a button in App X (with default appclip url) fails to launch the appclip for the first time but loads fine from the second try. I learned that in background Apple would make a API call to fetch details about app clip availability in store and then proceed to launch app clip locally, hence the delay->timeout->failure for first tap. Once the invocation starts working it would be consistent. After couple of minutes of break say 20m, it again fails for 1st time. I'm assuming that iOS is invalidating the cache on device regarding availability of appclip in store and hence the API call is made again and there is a delay and failure. can you please help us with this issue.

Hi all, Pretty new here, so please remember when you were trying hard. I am creating an IOS app that will generate a link where you have a room-id and a unique id. This will be sent (normal sms. email, copy/paste values etc) to another user. If the person receiving the link does not have the app installed, I would like it to go to the app store for download, however the app is currently not finished and therefore I can't provide a proper link. How do you deal with that? Thanks in advance

Hi, I work at OneSignal, a third-party SDK, and have the following two crash reports submitted by a client for the same issue. Because the crash originates from our SDK, even if the root cause may be elsewhere, the onus is on our team to try to resolve this crash. Additionally, my information is limited as this is not our own crash report. I'm trying to figure out why this crash happens and how we can address it within our SDK. Crash Reported: Fatal Exception: NSInvalidArgumentException [NSMutableDictionary __addObject:forKey:]: object cannot be nil Context: Our SDK makes a call to [NSUserDefaults(NSUserDefaults) objectForKey:] on the standardUserDefaults and passes in a non-null key. It appears further up the call stack, a null value is being added to a dictionary. I assume this is the innards of how the search list is generated. Additional Information: The client states that it seems to happen only once per user and the scale is not extremely high but it is increasing. They are unsure what happened and when. They don't have much information about the devices except it has happened on iOS 18.

Observed few times that providerDidBegin(_:) delegate never called for the complete app session after app init(as part of this CXProvider registered) which was built with SDK 26 and running on iOS 26. This issue observed multiple times with our testing. Since there is no providerDidBegin:, client is marking CallKit as not ready and never report any calls for VoIP APNS and ended up in app crash due to "[PKPushRegistry _terminateAppIfThereAreUnhandledVoIPPushes]" Please refer for sysdiagnose logs : FB19778306
