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?

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 am trying to add more than one ControlWidget in iOS 18 and I get an error and not sure whether I am doing anything wrong or there is a bug (or maybe it's not supported by design?)

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.

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!

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.

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? STEPS TO REPRODUCE 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".

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.

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, I'm new to coding for MacOS but I'm building a Godot app that I wish to be able to have create a virtual camera on MacOS via button click. I plan to use the GDExtension feature to interface with code for MacOS to do this. I was looking into what would be involved with this and came across the Camera Extension that can be bundled with MacOS apps that can be used to create a virtual camera. Is it possible to bundle this extension with a library or framework that I can then interact with using C++ in a GDExtension (an external app). I realise the extensions can only be registered from within the Application folder so the assumption is that the Godot app would be installed there.

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'm developing an extension on Xcode, trying to test on my iPhone 7 plus. When I connect my iPhone with my Mac that Xcode is running on, and click Run, the app shows up on my iPhone. But when I check Settings > Safari > Extensions, it says "NO EXTENSIONS INSTALLED. Extensions customize the way Safari works. Extensions can change the appearance or behavior of web content, add buttons to Safari, and more." I'm using : Xcode : Version 14.0.1 Mac OS monterey : Version 12.7.5 iPhone 7 plus : Version 15.8.2

I am developing a File Provider on Mac. I am marking some items within the domain as 'shared' via the NSFileProviderItemProtocol. However, the text 'Folder shared on iCloud by me' appears in Finder when these items are marked as shared. Is this correct? My provider has nothing to do with iCloud, which is, of course, the cloud developed by Apple. Is there a way to change this text or remove it? I've attached an image that shows the problem.

Hi There is a critical code section between the app and its app extensions that needs to be synchronized and done atomically. What would be a suitable solution to achieve locking and synchronization between app’s processes? Is there a way to share memory or an operation queue between the app and its app extensions? Thank you

Hi, how I should enable all kernel extension in Catalina 10.17 ? There is no "Allow" option or can't see it in start-up option.

I have an iOS SwiftUI app which uses some extensions like NotificationServiceExtension, NotificationContentExtension, WidgetExtension etc. I noticed that each extension uses its own process and has its own bundle with the .appex extension... and is packaged within the app bundle, with .app extension. In my case, most of my logic is in C++ and when the app starts up, it needs to 'startup' the C++ layer. Now, in WidgetExtension, if it's going to read data from disk and update its interface, I need to initialise my C++ layer first. The same can be said for NotificationServiceExtension. This is leading me to include all my C++ artefacts into the extension target as well. Here's my problem: If the size of my app (containing all my C++ artefacts) is 10MB and I'm using 20 extensions (say), the final size of the shipped app bundle is 10MB + (20 * 10MB) = 210MB, since extension bundle (.appex) is packaged within the app bundle (.app). Since the app and the extensions are using the same C++ artefacts, I was hoping to have one binary in the bundle. The app and its extensions will point to this binary. When the app is launched, the app entry point (struct conforming to App protocol) is invoked, in case of widget, the widget entry point (WidgetBundle) is invoked and so on for each extension. This will reduce the final size of the app bundle. Is it possible to have one binary and the app target, all extension targets would use this binary for there functioning?

Hello, technical friends, I am developing a custom keyboard extension, currently encountered a technical difficulty, almost asked AI and Google have not solved my problem. 

 Problem description: 
 When my App was first installed, I opened Settings from the App, enabled full access, and crashed when I returned to the App. Run the App for the second time, open the Settings from the App, update the full access permission, and automatically re-run the App after returning to the App, and then the third, fourth, and NTH times will not crash. 

 Seems like ios will kill host apps for custom keyboard extensions after full access is updated? I want my App installed for the first time to update full access to return App without crashing, but don't know how to fix this problem. I look forward to the technical experts working in Apple development to help me provide relevant technical methods and ideas so that I can solve this problem. Thank you very much! When tracing debugging in xcode, after the App forces exit, the console prompts： Message from debugger: Terminated due to signal 9 When I was monitoring CPU and memory usage, it was very low and I didn't see anything unusual.
