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, 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 have a Safari web extension that needs the ability to open the popup when the user interacts with a modal coming from the content script. There is a native message handler that comes with the safari web extension when you first create it: import SafariServices import os.log class SafariWebExtensionHandler: NSObject, NSExtensionRequestHandling { func beginRequest(with context: NSExtensionContext) { let item = context.inputItems[0] as! NSExtensionItem let message = item.userInfo?[SFExtensionMessageKey] os_log(.default, "Received message from browser.runtime.sendNativeMessage: %@", message as! CVarArg) let response = NSExtensionItem() response.userInfo = [ SFExtensionMessageKey: [ "Response to": message ] ] print("hit") context.completeRequest(returningItems: [response], completionHandler: nil) } } I have the permissions to send a native message, I've seen some examples online where you can access the SFSafariApplication module from SafariServices and open the popover. But I can't seem to access SFSafariApplication in this module.

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.

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 working on a banking application (includes iPhone and iPad) which includes add to wallet feature. During the implementation I saw one document it is mentioned that for iPad app, the app must be extended to support Apple pay functionality. Details from document says "Card Issuers with an iOS mobile banking app must support Card Issuer iOS Wallet extension functionality to enable Card issuer mobile app customers to provision new cards directly from the iOS Wallet app with all eligible Apple iOS devices. If the Card Issuer has a dedicated iPad App, that App must be extended to support Apple Pay functionality. " Is wallet extension implementation required for Apple pay to work in iPhone and iPad? Is wallet extension a mandatory implementation for Add to Apple Wallet feature to work and approved by Apple? I am little confused in this. Anyone who integrated Apple pay or done add to Apple Wallet feature recently without wallet extension faced any rejection? Any help would be much appreciated.

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.

Hi there, I have two extension in my App, a Finder Sync and a Share Extension. Because these are disabled by default and automatically enabling them is, according to my extensive research, not possible, I want to provide an easy way for the user to enable the extensions when the app is opened. I am currently displaying a popup, with a button to open the preferences. I have struggled with this a bit, by now I managed to open the main preferences window using NSWorkspace.shared.open(URL(string: "x-apple.systempreferences:com.apple.preference")!) which is rather suboptimal though, since the user has to select the extensions option manually and isn't directly redirected there. What I have also found is that the menu of the FinderSyncExtension can be opened directly by using FIFinderSyncController.showExtensionManagementInterface() which is unfortunately suboptimal as well, because it only shows the managment interface of the finder extension and not the overview of all extensions. Is there any way to either enable the extensions programatically, or if not, is there a way to show the "Added Extensions" portion of the Extensions menu in the system preferences?

Hi, in my Extension FilterDataProvider class that is inherited from NEFilterDataProvider i am trying to insert logs into my CoreData entity, but when i insert it gives me error "NSCocoaErrorDomain: -513 "reason": Unable to write to file opened Readonly Any suggestions please to update the read write permission i already have tried this way but no luck let description = NSPersistentStoreDescription(url: storeURL) description.shouldInferMappingModelAutomatically = true description.shouldMigrateStoreAutomatically = true description.setOption(false as NSNumber, forKey: NSReadOnlyPersistentStoreOption) ?

Hello, I am currently facing an issue with my iOS app and its associated Preview extension. I am trying to save a file to a shared container using App Groups, so that my main app can read the file. The code works perfectly on the iOS simulator, but when I run the app on a physical device I encounter a "You don't have permission to save the file" error. Here's the relevant code snippet: let appGroupIdentifier = "group.com.yourcompany.yourapp" func saveDataToSharedContainer(fileName: String, data: Data) -> Bool { guard let containerURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: appGroupIdentifier) else { print("Error: Unable to access the shared container.") return false } let fileURL = containerURL.appendingPathComponent(fileName) do { try data.write(to: fileURL, options: .atomic) print("Data saved to shared container successfully.") return true } catch { print("Error: Unable to save data to shared container. \(error)") return false } } I have already verified the following: App Groups capability is enabled for both the main app target and the extension target. The App Group identifier is consistent in both the main app target and the extension target, as well as in the Swift code. Provisioning profiles and signing certificates are up-to-date, and the issue persists after cleaning the project and resetting the provisioning profiles. Despite trying these steps, the issue remains unresolved. This error is reproducible in a new project with a Preview extension. I would greatly appreciate any insights or suggestions from the community to help me resolve this issue. Thank you in advance!

Our keyboard extension can be accessed independently in China region with native app like Notes or Safari, however the keyboard can only be opened in the app under same project in Taiwan region. I've checked some articles about how MDM managing extensions, also make sure our RequestOpenAccess option of keyboard extension info.plist also set to Yes. I'm not sure is there anything I missed, or I just need to inform client that they need to reach out their MDM manager and modify some restrictions? If keyboard supports mobile device management (MDM), it can work with managed apps. App extensions give third-party developers a way to provide functionality to other apps or even to key systems built into the operating systems Allow full access to custom keyboard in iOS

When i am fetching Images and passing it to await faceapi.fetchImage(label); then i am facing RefrenceError:Can't Find Variable: FileReader Please Help For this.

I'm using core data in app, widget extension and intent, but I found the data is not updated between targets. such as I added a new record in app, the widget is not updated unless remove the widget and re-add it. I added a new record in intent, the data in app is not updated unless I run the app again. I have set container.viewContext.automaticallyMergesChangesFromParent = true but it doesn't work. So how can I make the data is updated no matter it is modified any targets.

https://developer.apple.com/documentation/xcodekit/creating_a_source_editor_extension I created new MacOS project and added a Xcode Source Editor Extension target to the project.

There is an inconsistent issue when views are rendered from the Device Activity Report Extension. This issue is noticeable only on release versions and it works fine in debug mode. Around 80% of the times, the Report Views return blank screen and this is only the case when a weekly/monthly filter is used. Although, it works as expected for daily report views. My questions are: How are all the Report Activity Views working fine in debug mode but not in release mode? How the daily activity filter works fine in the release mode but the weekly/monthly filters don't work? Is this because of a memory limit issue in the extension? As of now, I have the family-controls(distribution) entitlement only for the app and for the extensions I only have family-controls(development) entitlement. Do I need to request for family-controls(Distribution) entitlement even for the extensions? I have seen threads on the forum mentioning the blank screen issue associated with the DeviceActivityReport but haven't found a solution to it. Any suggestions/feedback would be of great help, thanks.

Our app uses DeviceActivityReport to display the user’s screen time. The performance of DeviceActivityReport is often very poor. These issue occur commonly: Screen time is reported as 0 minutes DeviceActivityReport View appears completely blank The host app loses connection with the DeviceActivityReport altogether I have implemented several workarounds which only slightly improve the performance, to varying degrees depending on the device iOS: Inside the DeviceActivityReport code - retry fetching screen time data until it returns a non-zero result Implement a “refresh” button which reloads the DeviceActivityReport view from the host app However, due to the sandboxed nature of DeviceActivityReport, there is no way for the host application to tell if the DeviceActivityReport extension is experiencing these performance issues. It results in a really bad user experience. I am building the app with Xcode 14 due to another issue where DeviceActivityReport fails to load for all iOS 16 devices when built with Xcode 15 (this is a know issue, here’s a link to a discussion on the developer forums: https://developer.apple.com/forums/thread/735915). However, when testing on iOS 17 devices with Xcode 15 builds, the above issues still occur. I have received no crash reports from DeviceActivityReport. These issues are known bugs and have been discussed on the developer forums, but I haven't yet seen a solution. Other screen time apps exist that use the DeviceActivityReport seemingly flawlessly, so I know that there is a way to improve the performance of DeviceActivityReport in my app. Please help! I have been dealing with this poor performance for a long time now with almost no improvement!

There have been several posts (i.e. here, here) about the lagginess of the DeviceActivityReport extension. Often it takes a few seconds for the view to load, or sometimes doesn't show up at all. I've confirmed this is not a case of excessive memory usage in the extension (exceeding 100MB), because I've profiled the extension and it consistently maxes out at 10MB. I've placed a loading screen behind the DeviceActivityReport inside a ZStack in the host app in order to see if the lag is because it takes some time for the extension to spin up - but the loading screen does not appear, indicating that the extension is running right away, but receiving the view from the extension in the host app is where the lag happens. It's been extremely difficult to debug because the lag only occurs a fraction of the time, and DeviceActivityReport is pretty much a black box. There's no documentation about how the host app and extension actually communicate. I've also combed through the logs using the Console app on Mac with no indication of any issues, (but I do see the message "Connection to view service was invalidated" coming from the extension even when there is no lag). I'm pretty convinced that the problem lies in the host app, because when I strip everything away from the host app, DeviceActivityReport never lags. I suspect that there are processes running (network requests, async tasks, or state updates) that block the report view from being received in the host app. Could you please help me understand why this could be happening, with as many details as you could provide? Any details on how the host and extension communicate, what processes could block the view from appearing, or anything else. Seems like this is a common issue but plenty of apps also don't experience it. Any guidance you can provide would be extremely helpful, as I've been trying to fix this bug every since I've been working with this API with no luck. Thanks in advance!
