I have a multiplatform app for Mac and iOS, for which I am implementing a share extension. This share extension has to share settings with the app itself on both platforms. I am currently trying to achieve this by adding all targets to the same App Group and using UserDefaults with the App Group as suiteName. The app consists of three targets: A multiplatform SwiftUI app, an iOS Share Extension, and a macOS Share Extension,. Settings get persisted correctly on Mac and on the iOS 26 simulator. However, on a real iOS 26 beta 3 device, the Share Extension is unable to load UserDefaults (loading anything with the App Group as a suite name returns nil). What could cause this behavior? The following log entries are generated from the Share Extension on the iOS device, but not on the iOS simulator: Couldn't read values in CFPrefsPlistSource<0x1030d3c80> (Domain: MY_APP_GROUP, User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd 59638328 Plugin query method called (501) Invalidation handler invoked, clearing connection (501) personaAttributesForPersonaType for type:0 failed with error Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.mobile.usermanagerd.xpc was invalidated from this process."

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

My app uses CallKit and PushKit for real-time voice and video calls. I want to configure VoIP push notifications so incoming calls can wake the app, even when it’s in the background or terminated. Right now, I only see the normal Push Notifications option in my App ID settings and no VoIP Services section.

I am using AlarmKit in my app. When I access: AlarmManager.shared.authorizationState It always returns notDetermined, even when I have previously granted the app permission to use alarms via: try await AlarmManager.shared.requestAuthorization() Calling this API again grants me the permission though, without showing the permission prompt to the user. This sounds like a bug - if the permission has been granted, accessing authorizationState should return .authorized. It shouldn't require me to call requestAuthorization() again to update the authorization status again? Environment: iOS 26 beta 3 Xcode 26 beta 3

Greetings, I have set up two tips in my app, and my app is configured with Tips.configure([.displayFrequency(.daily)]. Tip 1 is set up with no options. Tip 2 has the IgnoresDisplayFrequency(true) option set: var options: [Option] { MaxDisplayCount(3) // We want the user to see these because it's important. IgnoresDisplayFrequency(true) } This option works as expected, as far as I can tell, in terms of making sure that Tip 2 is shown even if I've already seen Tip 1 today. If I interact with my app such that Tip 1 is displayed, and I then interact with it such that Tip 2 should be displayed, Tip 2 shows immediately, even though a day hasn't passed. However, if I do this the other way around, so that Tip 2 is displayed first, and then I interact so that Tip 1 should be displayed, my expectation would be that Tip 1 is not displayed, because another tip has already been shown today. I expected that it would not be shown until the following day, since it is not configured to ignore the tip frequency. That's not what happens, though. Tip 1 is displayed right away, even though Tip 2 has just been shown. This makes me think that setting IgnoresDisplayFrequency on Tip 2 is causing it to also be ignored when considering whether other tips should be shown. I did try omitting IgnoresDisplayFrequency option, and then as expected, only one tip is shown on a day, no matter which one is shown first.

I have made a screensaver for mac in swift, but couldn't find how to add an icon the logo image that shows up on saver file) and thumbnail (the cover image that shows up in the screensaver catalogue). Currently, it just shows a default blue spiral galaxy thumbnail and no icon image

When I call https://developer.apple.com/documentation/contactprovider/contactprovidermanager/enable() to request to use Contact Provider, I received a dialog with message like this "App Name would like to add its contacts as its own list. Contacts added this way can be removed from settings". I would like to support this message in Japanese or other languages. Is it possible?

I have an app developed by using the Callkit/Call-Blocking and received feedback from individual users, when using [cxcalldirectorymanager reloadextensionwithidentifier] to write call blocking data, it returned error code 11 with the following contents: errorCode: 11 errorDomain: com.apple.callkit.database.sqlite errorDescription: sqlite3_step for query 'DELETE FROM PhoneNumberBlockingEntry WHERE extension_id =?' returned 11 (11) errorMessage 'database disk image is malformed' I want to know the reasons for this error and how to solve it，Thanks!

Hi everyone, I’ve been stuck on an issue with iOS Universal Links for about a week and could really use some help. The problem When tapping a Universal Link on iOS, my Flutter app opens correctly (desired behavior) — but immediately afterward, Safari opens the same link in the browser. So both the app and the browser open. This only happens on iOS. On Android everything works as expected. What works If the link is simply the domain, like: https://mydomain.com …then the app opens without triggering the browser afterward. This is the correct behavior. What doesn’t work If the link includes a path or parameters, like: https://mydomain.com/path https://mydomain.com/path?param=value …then the app opens, and then the browser opens immediately after. What I’ve tried Verified my AASA file using Branch’s validator: https://branch.io/resources/aasa-validator/ → The AASA file is valid. Universal Links do open the correct screen inside the app — the issue is the unwanted second step (Safari opening). Behavior is consistent across different iOS devices. Extra details Using Flutter. Universal Links set up with the standard configuration (associatedDomains, AASA hosted at /.well-known/apple-app-site-association, etc.). Question Has anyone encountered this issue where Universal Links with paths/params open the app and then open Safari? What could cause iOS to trigger the browser fallback even when the AASA file is valid and the app handles the link correctly? Any insights, debugging tips, or known edge cases would be incredibly appreciated!

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

Is there any resource which describes this type of errors? I was integrating SKADNetwork view through Ad attribution and everything from the source app side is done and this error appears after the target app is installed and opened. Here is the full error Error setting install attribution pingback registered for app: <APP ID>, error: Error Domain=ASDErrorDomain Code=1209 "SKAdNetwork: Could not set registered for pingback that does not exist." UserInfo={NSLocalizedDescription=SKAdNetwork: Could not set registered for pingback that does not exist.}, result: 0 I cannot find any resource on the internet which gives any info about this ASDErrors. If anyone can help, you would be doing me a solid, Thanks in advance.

As of macOS 26 I have a menu item off a tray app that now is showing an exclamation mark by it when I have not defined one to show. Where is this coming from?

Original discussion pre iOS 26 Our app uses Auth0 with HTTPS callback, we've found the issue where AASA file is not ready immediately when app is initially launched, which is the exact issue from the above link. The issue seems mostly fixed on later versions on iOS 18, however, we are seeing some indications of a regression on iOS 26. Here's some measurement over the last week. | Platform | iOS 18 | iOS 26 | |---------------|----------|--------| | Adoption rate | 55% | 45% | | Issue seen | 1 | 5 | | Recover? | Yes | No | This only 1 iOS 18 instance was able to recover after 1 second after the first try, however, all iOS 26 instances were not able to recover in couple tens of seconds and less than 1 minute, the user eventually gave up. Is there a way to force app to update AASA file? Are there some iOS setting (like using a VPN) that could potentially downgrade the AASA fetch?

Certainly! Here's a concise version of your forum post: Title: Issues Handling Multiple Incoming Calls in CallKit Body: Hello, I'm using CallKit and I am encountering challenges with handling multiple incoming calls. Current Configuration: configuration.maximumCallsPerCallGroup = 5 configuration.maximumCallGroups = 3 This setup aims to allow up to 5 calls per group. Observed Behavior: Despite the configuration, the system UI seems to limit the number of calls per group, often defaulting to "End & Accept" instead of "Hold & Accept" when a third call comes in. Questions: Is there a documented system-imposed limit on the number of calls per group or total calls, even if maximumCallGroups and maximumCallsPerCallGroup are set higher? How does the system UI behave when these limits are exceeded? Are there known UI constraints or fallback behaviors? Are there best practices for handling scenarios where the system UI cannot display all calls, such as gracefully managing incoming calls or providing alternative UI solutions? Any insights or experiences with similar configurations would be greatly appreciated. Thank you. Feel free to copy and paste this directly into the Apple Developer Forums. If you need further assistance or adjustments, let me know!

On macOS 26, I've run into a situation when a user “customizes” a folder icon with Finder by assigning/changing an SF Symbol or an emoji, QLThumbnailGenerator keeps returning the stale initially retrieved folder icon (no matter whether it had been customized or not) until my app quits. After the app is re-launched, the icon is correctly retrieved once again. let generator = QLThumbnailGenerator.shared let size: CGSize = CGSize(width: 64, height: 64) let request = QLThumbnailGenerator.Request(fileAt: url, size: size, scale: NSScreen.main!.backingScaleFactor, representationTypes: .icon) request.iconMode = true do { let thumb = try await generator.generateBestRepresentation(for: request) thumb.nsImage.size = size return thumb.nsImage } catch { print("generateThumbnail: \(error)") return nil } It seems like the QuickLook Thumbnailing cache does not invalidate automatically upon folder customization. Is there any way to manually invalidate the QuickLook Thumbnailing cache?

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

On macOS, one can set the "Open With ..." application in the information panel of a file without changing the default for this file type. However, doing this for a number of files is very tedious. A simple case is to change all .txt files in a directory to a special editor, but leave the system wide default (usually TextEdit). I have tried AppleScript, command line tools as well as a minimal GUI app (using LSSetItemAttribute), but all fail because of a lack of permission. Is there any way to achieve this?

How can experimentation and testing calling the AgeRangeService.shared.requestAgeRange() functionality be recreated easily? The very first time I ran this the OS popped up a dialog, however it won't do so again, even after the app is deleted and the device re-started. If one navigates to Settings/User/Personal Information/Age Range for Apps/Apps that have requested your age range appear here. Then the names of apps appear here even after the app has been deleted. Therefore how can it be removed from this section? Erasing and resetting the phone will presumably reset things back to a state such that the dialog can be presented again. But doing that and having to wait for that to complete each development or test run is impractical. Is there an alternative?

We are not receving incoming call from blocked numbers below iOS 26 versions but same in iOS 26 onwards we are receiving the incoming call.. Can you please provide any solutions to fix the issue

I'm working on adding MetricKit to our iPad application that we distribute internally via Enterprise distribution. I've set up the didReceive functions for both MXMetricPayload and MXDiagnosticPayload. When I build onto a device via Xcode and use the Simulate MetricKit Payloads command, everything works as expected. The issue I'm having is when testing on a device via our enterprise distribution. When I simulate a crash, I am receiving the MXDiagnosticPayload so that part is working correctly. However, I am never receiving a MXMetricPayload. I've been using the app and waiting up to 3 days in some tests and not receiving any payload over that time frame. Some information I found suggested the issue might be MetricKit not working fully on enterprise apps but I haven't been able to find a definitive source on that question. Hoping someone here can guide me on that. Thanks!
