Hi, I am developing QuickLook Thumbnail Extension and QuickLook Preview Extension which work with embroidery files. To prepare the view, I need to access stitches from the "stitch" file (supplied to my extension by system) and also to read the "colors" from related file (i.e. the file with different extension, but the same filename as "stitch" file). The embrodery is located stored in 2 files: squirrel.dst (stitchs) and squirrel.edr (colors). Is it even possible to extend sandbox in extensions for this task? I have tried to ask user to select folder in main.app (NSOpenPanel), create security-scoped Bookmark in main.app and access it from extension. However, this is not working - in the extension it is not possible to resolve the bookmark created in main.app. I have also tried to use mechanism for accessing related files as shown at https://developer.apple.com/documentation/security/app_sandbox/protecting_user_data_with_app_sandbox, using NSFilePresenter/NSFileCoordinator. It works in main.app, but doesn't work in QuickLook Thumbnail Extension and QuickLook Preview Extension. Is there any mechanism on Mac which would allow me to access more than the "supplied" file URL in QuickLook Thumbnail Extension and QuickLook Preview Extension? Ladislav

I have an iOS app which uses Notification Service Extension (NSE) to process incoming notifications before it displayed to user. In NSE, as part of initialization of my app, I need to iterate through a 2D array. There are roughly 65k iterations. I've noticed that this iteration fails somewhere in between and the NSE process crashes... I can say it crashes because the logs stopped in between the iterations. This results in 'unmodified notification' getting displayed immediately, whereas NSE is granted 30 sec of background execution. My question is, why does this happen? The above iteration of 2D array works in app, but fails in NSE. Is there some kind of restriction on background extensions? - the documentation only talks about a time limit of 30sec. If there is some kind of restriction (like CPU and memory), how does one know this and code for it... since Apple did not provide any documentation. Or perhaps, there is a completely different reason?

Hello, I'm experiencing an issue with enabling a Content Filter Network Extension from a command line tool. When I call the LoadFromPreferences method on NEFilterManager.shared() the completion handler is not called. I've tried this with a simple semaphore and tried running it on a RunLoop, but none of this works. Any help would be appreciated. I've tried adding a small demo project illustrating the issue, but the add file option does not seem to work. I'll paste the code here: Semaphore Demo class SemaphoreDemo { let filterManager = NEFilterManager.shared() var semaphore = DispatchSemaphore(value: 0) func demo() { print("Semaphore demo") self.filterManager.loadFromPreferences { (error) in print("Load from preferences callback") if let error = error { print("ERROR \(error.localizedDescription)") return } let config = NEFilterProviderConfiguration() config.filterDataProviderBundleIdentifier = "BUNDLE_IDENTIFIER" config.filterSockets = true self.filterManager.isEnabled = true self.filterManager.localizedDescription = "LOCALIZED_DESCRIPTION" self.filterManager.providerConfiguration = config self.filterManager.saveToPreferences { (error) in if let error = error { print("ERROR \(error.localizedDescription)") } else { print("SUCCESS") } self.semaphore.signal() } } self.semaphore.wait() } } class RunloopDemo { let filterManager = NEFilterManager.shared() func demo() { print("Runloop demo") let currentRunLoop = CFRunLoopGetCurrent() // let currentRunLoop = CFRunLoopGetMain() self.filterManager.loadFromPreferences { [weak currentRunLoop] (error) in print("Load from preferences callback") if let error = error { print("ERROR \(error.localizedDescription)") return } let config = NEFilterProviderConfiguration() config.filterDataProviderBundleIdentifier = "Bundle IDENTIFIER" config.filterSockets = true self.filterManager.isEnabled = true self.filterManager.localizedDescription = "LOCALIZED DESCRIPTION" self.filterManager.providerConfiguration = config self.filterManager.saveToPreferences { (error) in if let error = error { print("ERROR \(error.localizedDescription)") } else { print("SUCCESS") } CFRunLoopStop(currentRunLoop) } } CFRunLoopRun() } } The callback is never called. Thanks.

We had developed an iOS Safari web extension (which uses non-persistent background scripts) that functioned properly until iOS 17.3. However, I've encountered inconsistent behavior on iOS 17.4.1, 17.5, and 17.5.1. Upon further debugging, I noticed that the background scripts often become idle and are unloaded frequently. They are not loaded again even for the registered webNavigation events and only trigger when interacting with the extension popup menu. This is also mentioned here. I had tried this in both manifest versions 2 & 3. I had tried using service_worker for background scripts. But, none of it seems to resolve this issue. Could you please clarify if this is a bug or an intended behavior? Our extension relies on webNavigation events without users having to interact with the popup menu often.

I am writing to follow up with my lab in WWDC24. I had 1:1 lab with Mr. Kavin, we had good 30 minutes lab and for follow up questions Kavin asked me to post it using feedback. Following is my questin: We have screenshare in our application and trying to use CFMessagePort for passing CVPixelBufferRef from broadcast extension to Applicaiton. Questions: How to copy planes of IOSurface backed CVPixelBufferRef onto another one without using memcpy, is there a zero-copy method? How to get notified when an IOSurface backed CVPixelBufferRef data get changed by another process. How to send an IOSurface backed CVPixelBufferRef from Broadcast Extension to application. How to pass unowned IOSurfaceRef from the Broadcast Extension to appliction.

We use a local swift package in 6 of our app extensions. The product from the local package that we link to each app extension is a dynamic framework. And while the dynamic framework is copied into the final app bundle once, the resource bundles of each target that comprise the dynamic framework is copied into each app extension. I'd much rather have the bundles be copied into the dynamic framework once to prevent app bloat. Here is a visualization of the issue: . └── MyApp.ipa/ ├── MyApp (executable) ├── MyDynamicFramework_TargetA.bundle ├── MyDynamicFramework_TargetB.bundle ├── MyDynamicFramework_TargetC.bundle ├── Frameworks/ │ └── MyDynamicFramework.framework/ │ ├── TargetA │ ├── TargetB │ └── TargetC └── PlugIns/ ├── Widgets.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── Intents.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── IntentsUI.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── NotificationContent.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── RichPushContent.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle └── NotificationService.appex/ ├── MyDynamicFramework_TargetA.bundle ├── MyDynamicFramework_TargetB.bundle └── MyDynamicFramework_TargetC.bundle Notice that the resource bundles of Target A, B, and C are copied multiple times causing an unhealthy app size. I'd either like the resource bundles to be copied into MyDynamicFramework or copied once into the app bundle and let the app extensions reference them. Given the SPM + Xcode linking is a black box for the most part, how would I accomplish this?

While Implementing Wallet Intent Extension, and after verification The only message i get is Cannot Add Card There are no available cards to add. Any help here is appreciated.

In the documentation of deferQueryRequestToNetwork method which is used to do a network request on message filter extension. There is no mention of timeout period applied to network requests. https://developer.apple.com/documentation/sms_and_call_reporting/ilmessagefilterextensioncontext/2880240-deferqueryrequesttonetwork So my question is what is the timeout period of the deferQueryRequestToNetwork method? And is there some changelog to know has this value changed in some iOS version.

I'm the developer of a third-party keyboard app, Snippety - Snippets Manager, which is designed for using snippets rather than regular typing. One of my users has encountered a strange issue: after installing my keyboard (even when it is not actively in use), the predictive text bar starts showing suggestions in Polish. This happens despite the Polish language not being installed on the device. The issue resolves as soon as my keyboard is uninstalled from the system settings. Interestingly, my application (including the keyboard) does not support the Polish language, nor is Polish specified anywhere in the app. The app was developed and published from macOS in English. This seems to be an iOS bug. The only language-related configuration in my keyboard is the PrimaryLanguage key in the Info.plist file, which I set to "mul" because the keyboard is not intended for typing. I also tried setting it to "mis", but the issue persists. The video presenting this issue on an iPhone 15 simulator running iOS 17.5: https://www.dropbox.com/scl/fi/xjdyucxpmv1cv0mnmwzvd/prdictive-text-issue.mp4?rlkey=aphznpdti08pz8xl84ojbyxz3&dl=0 Info.plist for my keyboard: My project settings: Steps to reproduce: Configure iOS to use English language only, with English keyboard Enable predictive text feature in the system Install Snippety keyboard Use the regular keyboard & start typing "dzie" Actual result: Polish predictions appear even though the Polish language is not installed or declared by the keyboard. Expected result: The predictive text should present predictions based on system settings. What is even more weird, I discovered that when I add the keyboard in system settings, it automatically installs Polish language in the system settings. I even changed PrimaryLanguage to "de" (German) in Info.plist but it still installs Polish. See: https://www.dropbox.com/scl/fi/aiv5g4z331zwy827zj47v/incorrect-language-installed.mp4?rlkey=16v5gqmb6mj8yuyyd7jwmjnsw&dl=0 Any ideas what could be wrong? I also created a ticket: #FB13949087 I also found a similar issue from 2018 (O_O) reported here: https://stackoverflow.com/questions/53069262/ios-adds-new-preferred-language-when-installing-my-3rd-party-keyboard

I am writing this Web Extension for Safari. It is designed to run on both macOS and iOS. The extension-specific javascript/css/etc files are shared between the platforms. What I observe is that the extension is running fine on macOS. It also runs fine on the iOS Simulator. However, on my device, just nothing happens when activating the extension. No errors are output to the console either. I found it out the hard way, when I already released the extension in the AppStore, and installed it on a friend's iPhone. Does anyone have a clue where I even could start debugging? Or better: maybe there is just a simple checkbox that that I should (un)check?

I'm developing a single target watchOS app that obtains HealthKit information. I have the "Background Delivery" option checked under "Signing & Capabilities" for the watch target. The app does HKObserverQueries in the foreground that work as I would expect. But when I click the Digital Crown to return to clock face, the HKObserverQuery activity stops. I'm using Xcode 15.4, on Mac 14.5 and a Apple Watch Series 4 running 10.5.

When using ExtensionKit, is it expected that an app would be able to open concurrent XPC connections to both an extension process (via AppExtensionProcess.makeXPCConnection) and that extension's scenes (via EXHostViewController.makeXPCConnection)? I'm finding that if I make a connection to an extension process, communication with the process works fine until I try to make a connection to a scene in that extension ... at which point the extension receives SIGKILL and an OSLaunchdErrorDomain code 137 "Service does not support the specified action" error is logged to the console. Similarly, if I first make one or more connections to extension scenes, communication with the scenes works fine until I try to make a connection to the extension process ... at which point the same result and error occur. So it seems that I can either communicate with an extension process or that extension's scenes, but not both. Is this an expected limitation, or should I be able to communicate with an extension process and its scenes at the same time?

Hi, Can I use the MailKit API to add mention support to Mail App. Where I write "@deepak" and my extension suggests me emails starting with the name "deepak" from my contacts. I see there is MEComposeSessionHandler.viewControllerin the mail kit API. But I think, according to the WWDC demo, it can only create UI in the toolbar section of the compose window. Any help will we appreciated here!

macOS MacOS 14 Apple Silicon DESCRIPTION OF PROBLEM GlobalProtect(GP) and AnyConnect(AC) are both VPN apps. They both create a TUN interface and set default route to this interface. Test cases: AC connect first and GP connect second, both work fine. GP connect first and AC connect second, AC failed with some "route error". Our question is why the route failed for AC if GP already set the default route? Does MacOS has some limitations for the default route?

I am developing a FileProvider extension on Mac. I was wondering what the most reliable way to evict a document as soon as possible after createItem is called for the respective item. Our use-case for this is as follows: Users can 'bulk-import' items into a FileProvider folder, and we want our application to immediately evict the item as soon as possible once the item's content is uploaded to the server. This is to save space on the user's machine. So, what is the best way to accomplish immediate eviction after item creation? I've tried calling evictItem from within the createItem function itself, but that yields many errors and can cause slowness.

I am developing a Mac File Provider Extension. When testing installation from-scratch, The File Provider Name does appear on the side bar. However, the text '[App Name] encountered an unexpected error. Items may be out of date .....Try Again' appears at the top of the Finder window when opening the File Provider's Domain. Along with this text, there is a persistent 'Loading...' that is displayed in the middle of the Finder view. The File Provider seems to immediately get in a bad state. This does not happen at all during development. I am also noticing some logs in console that indicate some sort of issue. These 3 seem to be relevant.
