I'm developing an app that receives push notifications, and writes the contents of the push notification to a shared location between the main app and a Notifications Message Extension, through App Groups. This all seems to work on my phone, with developer mode turned on, but when I archive my app as an Enterprise IPA and distribute it, the users can install the app on their phones and they receive the push notifications, but it doesn't appear that the message extension is running as my app displays the content of the shared data in the App Groups on the main screen and nothing is showing. I have tried on 3 phones, and it only works on the phone with developer mode turned on. I can't tell at this point whether it's because of a signing issue, or build phase order issue, or something else?

I’d like to submit a feature request regarding the availability of Foundation Models in MessageFilter extensions.
Background
MessageFilter extensions play a critical role in protecting users from spam, phishing, and unwanted messages. With the introduction of Foundation Models and Apple Intelligence, Apple has provided powerful on-device natural language understanding capabilities that are highly aligned with the goals of MessageFilter.
However, Foundation Models are currently unavailable in MessageFilter extensions.
Why Foundation Models Are a Great Fit for MessageFilter
Message filtering is fundamentally a natural language classification problem. Foundation Models would significantly improve:
Detection of phishing and scam messages
Classification of promotional vs transactional content
Understanding intent, tone, and semantic context beyond keyword matching
Adaptation to evolving scam patterns without server-side processing
All of this can be done fully on-device, preserving user privacy and aligning with Apple’s privacy-first design principles.
Current Limitations
Today, MessageFilter extensions are limited to relatively simple heuristics or lightweight models. This often results in:
Higher false positives
Lower recall for sophisticated scam messages
Increased development complexity to compensate for limited NLP capabilities
Request
Could Apple consider one of the following:
Allowing Foundation Models to be used directly within MessageFilter extensions
Providing a constrained or optimized Foundation Model API specifically designed for MessageFilter
Enabling a supported mechanism for MessageFilter extensions to delegate inference to the containing app using Foundation Models
Even limited access (e.g. short text only, strict execution limits) would be extremely valuable.
Closing
Foundation Models have the potential to significantly raise the quality and effectiveness of message filtering on Apple platforms while maintaining strong privacy guarantees. Supporting them in MessageFilter extensions would be a major improvement for both developers and users.
Thank you for your consideration and for continuing to invest in on-device intelligence.
Hello,
We are trying to use the new Background Upload Extension to improve uploads of assets (Photos, Live Photos, Videos) in the background in our application.
1 - We implemented the code to upload still images.
We would like to do the same for Live Photos but we are not sure how to proceed since a Live Photo is composed of 2 resources that we would like to upload in the same job so that we keep the association between the 2
resources.
Steps:
A Live Photo is captured on the device.
Our application is notified for new content in the Photo Library and the asset is queued for upload by our application.
The system calls the background upload extension and the Live Photo is prepared for upload but we can schedule a job only for one resource (still photo or paired video) so we can not upload both resources in a single job.
2 - Is there a way to synchronise the application and the extension so that the application would not process the same data or execute the same requests than the extension. For example: our application is working with
tokens and we would like to prevent those tokens to be consumed by the application and the extension at the same
time.
3 - is there a command in xcode or terminal to start or stop the extension, something similar to what exists for processing tasks
(https://developer.apple.com/documentation/backgroundtasks/starting-and-terminating-tasks-during-development).
Hi, I’m trying to integrate my iOS app with Shortcuts.
My goal is:
In the Shortcuts app → Create a shortcut → Select an image → Share the image directly to my app for analysis.
However, when I try to add the “Share with App” / “Open in App” / “Send to App” action in Shortcuts:
My app does NOT appear in the list of available apps.
I want my app to be selectable so that Shortcuts can send an image (UIImage / file) to my app.
What I have tried
My app supports receiving images using UIActivityViewController and Share Extension.
I created an App Intents extension (AppIntent + @Parameter(file)...) but the app still does not appear in Shortcuts “Share with App”.
I also checked the Info.plist but didn’t find any permission related to Shortcuts.
The app is installed on the device and works normally.
My question
What permission, Info.plist entry, or capability is required so that my app becomes visible in the Shortcuts app as a target for image sharing?
More specifically:
Which extension type should be used for receiving images from Shortcuts?
App Intents Extension?
Share Extension?
Intent Extension?
Do I need a specific NSExtensionPointIdentifier for Shortcuts integration?
Do I need to declare a custom Uniform Type Identifier (UTI) or add supported content types so Shortcuts knows my app can handle images?
Are there any required entitlements / capabilities to make the app appear inside the “Share with App” action?
Goal Summary
I simply want:
Shortcuts → Pick Image → Send to My App → App receives the image and processes it.
But currently my app cannot be selected in Shortcuts.
Thanks in advance for any guidance!

App Intents
I have recently added a SetFocusFilterIntent target extension to my app which is a system utility which goes into the menu bar(Application is agent = YES). I have followed the approach in the WWDC22 video introducing Focus Intent and I have created an App Groups to being able to make the Extension to communicate with my main app, however from when I did this sometimes when I run the app I do get this log line:
Couldn't read values in CFPrefsPlistSource<0x97cd34700> (Domain: group.xxx.xxx.MyApp, User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd
Despite this the Focus mode integration is working correctly on my development Mac. However I used to Archive the app and then Copy the app to my MacBook but when I do that now my other Mac cannot open the app and it is giving me an error. If I revert this change then I can bring the app back to my other Mac as usual following the procedure: Product -> Archive.
Then from the archiver: Distribute App -> Copy App. After that I copy the app generated to the App folder of my other MacBook but it doesn't open anymore.
During the archival phase now I am even getting this warning:
MyAppFocus.appex is an ExtensionKit extension and must be embedded in the parent app bundle's Extensions directory, but is embedded in the parent app bundle's ../../../BuildProductsPath/Release/MyApp.app/Contents/Extensions directory.
How can I solve this issue?
If I rollback the commit related to this SetFocusFilterIntent new feature the app can be Copied and moved to the other Mac as before.
Is this related to the extension or to the fact that I had to use this new entitlement: com.apple.security.application-groups ?
I'm trying to test the update process for an app containing an FSKit module that I'm distributing on the Mac App Store. (I'm also distributing the same app directly with Developer ID, but here I'll focus on App Store because that's the behavior I've been looking at first.) To do that I'm using an internal tester group on TestFlight and then testing an update with TestFlight. Below is the behavior I'm seeing on macOS 15.7.2 (24G325).
I've noticed that if an app update is triggered while a disk is mounted using the FSKit extension, the disk is automatically unmounted without warning (FB21287341). That's already undesirable itself in my opinion, but on top of the unmount, there are two other problems:
That unmount doesn't seem to be a "clean" unmount and doesn't call functions like synchronize (FB21287688). Now, in my case, my app only provides read-only access, so that doesn't actually matter much in my case. However, I'd imagine if I were to add write access at some point in the future, this would go from "doesn't matter" to "very bad."
I've seen a few cases where quitting or crashing the FSModule process while a volume is mounted without actually doing a clean unmount causes a lot of "disk-related actions" (for lack of a better term) to freeze (FB21305906). For example, a use of the mount(8) command or trying to mount a disk at all freezes, and opening Disk Utility stalls on a "Loading disks" spinning indicator. This happens until the Mac is rebooted. I did notice this issue once while testing updates via TestFlight a few times.
The same applies if I simply delete the app with Finder instead of updating it.
Is there a way to prevent the extension's process from terminating in this case and/or another workaround I could use without waiting for a macOS update to hopefully change this behavior?
And does observing this kind of behavior with TestFlight's update behavior suggest the same thing could happen on the App Store with its automatic updates? I'm concerned that pushing an update via the App Store will unexpectedly unmount disks or cause the system-wide issues described in FB21305906 at a random time, which is a pretty big disruption for users.
Hi there,
I'm trying to work on an architecture where one app exposes an API (Extension Host) that other apps can plugin to. I've been reading all I can from the docs and whatever I can find online. It seemed like iOS26 added the ability to do such a thing (at least in early builds).
Is that the case?
Has the functionality been walked back such that extensions can only be loaded in iOS from within the single app bundle?
My use case is the following:
I'm working on an agent app that desires to have 3rd party developers add functionality (think how MCP servers add functionality to LLMs). The 3rd party plugins would be provided in their own app bundles vetted by the AppStore review team, of course, and would only provide hooks, basically, the main app can use to execute functions or get state.
This is the best thread I found on the topic, and the subtext is that it needs to be in the same bundle. https://developer.apple.com/forums/thread/803896?answerId=865314022#865314022
Let's say for the moment that this isn't possible using ExtensionKit. What's the best way to achieve this? Our current best alternative idea is a hidded WebKit window that runs JS/WASM but that's so hackish.
Please let me know, thanks!
I want to use FileProvder to implement the function of recovering from the recycle bin (the cloud recycle bin does not move, and after the local recycle bin is restored, the upload event is triggered again), but testing shows that the current recovery from the recycle bin is through the modifyItem event, and the CreateItem event is not triggered again to upload locally restored files
Implement the deletion of undelivered files (dateless) without moving them to the recycle bin, which currently appears to be achieved by granting file. dash permission. But it is possible for the content of a file to be manually verified by the user. How can this be solved? How can we dynamically monitor whether a file is dataless
Thank you for your reply. Could you please help answer my question
It looks like ExtensionKit (and ExtensionFoundation) is fully available on iOS 26 but there is no mention about this in WWDC.
From my testing, it seems as of beta 1, ExtensionKit allows the app from one dev team to launch extension provided by another dev team. Before we start building on this, can someone from Apple help confirm this is the intentional behavior and not just beta 1 thing?
From watching the video on App Attest the answer would appear to be no, but the video is a few years old so in hope, I thought I would post this question anyway.
There's several scenarios where I would like a notification service extension to be able to use App Attest in communications with the back end(for example to send a receipt to the backend acknowledging receipt of the push, fetching an image from a url in the push payload, a few others).
Any change App Attest can be used in by a notification service extension?
I'm trying to develop an app that broadcasts what the user sees (priorly we were using main camera access) but now we'd like to investigate and try with this option.
I have set up the BroadcastExtension, I've added the picker, I click on my button, I can see my broadcast extension in the options list in the control center, once I click start, it stops after 1 second more or less.
I'm not able to get anything in the console from my Sample Handler (prints or logs or anything).
I can see however in the console.app some misleading information (one after the other):
[INFO] -[RPRecordingManager getSystemBroadcastExtensionInfo:]_block_invoke:1333 Extension has passthrough license
[INFO] -[RPRecordingManager getSystemBroadcastExtensionInfo:]_block_invoke:1336 Extension does not have passthrough license
We have the entreprise license, the capability and I did add the capability on the extension target as well.
I would love to partake in beta testing and reporting issues and bugs! Let me know what you got

We use File Provider Extension in our main app, and it is working fine.
We always call "NSFileProviderManager.add(_:completionHandler:)" function to start the extension, and "NSFileProviderManager.disconnect(reason:options:completionHandler:)" to temporarily quit the extension with the reason which will be shown in the Finder at the top of the FP domain folder.
But sometimes, when the main app calls the above functions, the following issue cases occur, and the extension does not start/stop:
The completionHandler function doesn't get called (As we noticed, we waited for 2 minutes. Then, we restarted the main app.)
One of the following errors returned: i) "The application cannot be used right now", ii) "Couldn't communicate with the helper application", iii) "No valid file provider found with identifier"
Here, the important thing is that restarting the main app once or twice clears the issue, and the extension starts.
But it is frustrating to restart the app each time we get this issue.
We want to know the following things:
Why and when do the above issues occur?
Why do they occur only sometimes, and how does the app restart clear the issue?
How do we resolve them without restarting the main app?
This has become a critical issue, so a detailed explanation would be greatly appreciated. TIA.

Hi, I have an iOS project with the following app targets:
main iOS application
a notification service extension
5 static libs containing some swift files with public methods
1 dynamic framework with above static libs as dependencies.
The framework only contains 2 files - a default .h file and 1 .exp file. This exports file contains mangled-names of all the public methods that are exposed by the 5 static libs present as framework's dependencies. I obtained these symbols using the nm command for each static lib.
The main iOS app target has 2 dependencies - the framework and the notification extension.
The notification extension only depends on the framework.
This setup works perfectly fine. I wanted to understand:
If using the exports file is the only way to make this setup work?
If not, what else can I do?
What way does Apple recommend?
According to my requirements, I only need at-most 2-3 functions to be exposed by the framework - thus using a exports file just for that seems to bug me.
Thank you.
I'm developing a custom file system using FSKit. After testing some example projects on github and have encountered an issue where the removeItem(_:named:fromDirectory:) method in my FSVolume.Operations implementation is not being invoked when attempting to delete files or directories through Finder or the command line.
Environment:
macOS: macOS 26.1
Xcode: 16.2 / 17A400
Sample Project:
https://github.com/KhaosT/FSKitSample
https://github.com/debox-network/FSKitBridge
My volume implements the required FSVolume.Operations protocol with the following removeItem implementation:
func removeItem(
_ item: FSItem,
named name: FSFileName,
fromDirectory directory: FSItem
) async throws {
logger.info("remove: \(name)")
if let item = item as? MyFSItem, let directory = directory as? MyFSItem {
directory.removeItem(item)
} else {
throw fs_errorForPOSIXError(POSIXError.EIO.rawValue)
}
}
Steps to Reproduce:
Mount the custom FSKit-based file system
Create files using Finder or terminal (works correctly - createItem is called)
Attempt to delete a file using:
Terminal command: rm -rf /path/to/mounted/file
option+cmd+delete force to delete file
Expected Behavior:
The removeItem(_:named:fromDirectory:) method should be called, logging "remove: [filename]" and removing the item from the directory's children collection.
Actual Behavior:
The removeItem method is never invoked. No logs appear from this method. The deletion operation either fails silently or returns an error, but the callback never occurs.
Are there specific volume capabilities or entitlements required for removeItem to be invoked or are there any known issues with deletion operations in the current FSKit implementation?
Any guidance would be greatly appreciated.
I have an iOS app with ExtensionFoundation. It runs well on my local device, but when I upload on the AppStore it gets rejected with:
Validation failed
Invalid Info.plist value. The value of the EXExtensionPointIdentifier key, AsheKube.app.a-Shell.localWebServer, in the Info.plist of “a-Shell.app/Extensions/localWebServer.appex” is invalid.

Description :
Our app helps users connect to Wi-Fi hotspots. We are trying to adapt our code to iOS 26 Hotspot Authentication and Hotspot Evaluation application extensions.
When filtering hotspots in the filterScanList callback, we need to fetch support information from a remote server to determine which hotspots are supported. However, attempts to use URLSession or NWTCPConnection in the extension always fail.
When accessing a URL (e.g., https://www.example.com), the network log shows:
Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found."
When accessing a raw IP address, the log shows:
[1: Operation not permitted]
Interestingly, NWPathMonitor shows the network path as satisfied, indicating that the network is reachable.
Question:
Are there any missing permissions or misconfigurations on our side, or are we using the wrong approach? Is there an official recommended way to perform network requests from an NEHotspotEvaluationProvider extension?
If the extension uses manifest v3 and a background script in the form of a service worker, then in Safari it is not possible to open the background script debugging window. If I expand the Developer menu in Safari, there is nothing under Web Extension Background Data (or disappear after click), which is an error. In other browsers (Edge, Chrome, Opera, Firefox) this works correctly.
If I switch the background script back to non-persistent script mode, everything works fine and from the Developer menu and the Web Extension Background Data submenu I am able to open the background script debugging window for the extension. Am I doing something wrong?
