Hi everyone, I’m developing an Electron application on macOS and I’m trying to register and activate a macOS System Extension, but I’m running into startup and entitlement issues. 🔧 What I’m trying to build • An Electron app packaged with electron-builder • Signed with Developer ID Application • Notarized using @electron/notarize • A macOS System Extension is already built and signed • The System Extension provides a virtual camera • I wrote a Swift helper that: • Registers / activates the virtual camera • Calls OSSystemExtensionManager • This Swift code is compiled into a .node native addon • The .node module is loaded and called from Electron (Node.js) to trigger system extension registration ❗ The problem When I add the following entitlement: com.apple.developer.system-extension.install the application fails to launch at all on macOS. Without this entitlement: • The app launches normally • But system extension activation fails with: Error Domain=OSSystemExtensionErrorDomain Code=2 Missing entitle

For general background on this, see TN3179 Understanding local network privacy. As to your specific scenario: What platform are you on? While the local network privacy implementation is very similar on macOS and iOS, there are important differences. As you concerned about Safari? Or about a web view running in your app? That difference is important because a web view running in your app is considered to be your app from the perspective of local network privacy.

[quote='811084021, iceboy, /thread/811084, /profile/iceboy'] its value keeps changing and then switching back to the original [/quote] Can you expand on this? When does it change? Between different runs of your app? Or across OS upgrades? Or something else? Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

This is just an FYI in case someone else runs into this problem. This afternoon (12 Dec 2025), I updated to macOS 26.2 and lost my network. The System Settings' Wi-Fi light was green and said it was connected, but traceroute showed No route to host. I turned Wi-Fi on & off. I rebooted the Mac. I rebooted the eero network. I switched to tethering to my iPhone. I switched to physical ethernet cable. Nothing worked. Then I remembered I had a beta of an app with a network system extension that was distributed through TestFlight. I deleted the app, and networking came right back. I had this same problem ~2 years ago. Same story: app with network system extension + TestFlight + macOS update = lost network. (My TestFlight build might have expired, but I'm not certain) I don't know if anyone else has had this problem, but I thought I'd share this in case it helps.
Hi everyone, We’re running into a serious issue with App Clip Experience updates not propagating to devices, and I’m hoping someone here has encountered (or solved) this before. Problem Once an App Clip Experience is created and used on devices, subsequent updates made in App Store Connect do not reflect on any devices, even after a long period of time. We’ve tried: • Updating the App Clip Experience URL (adding utm parameters, for example, utm_source and scanning via QR code) • Modifying Experience metadata/content • Waiting several days (over a week) • Testing on multiple devices (including devices that never opened the App Clip before) Despite this, the App Clip continues to show the initially created content, while App Store Connect clearly shows the updated configuration. Important Details • We currently have ~1,300 App Clip Experiences created • All App Clips use the same App Clip Bundle ID • The content behind the URLs updates correctly on the website • Only the App Clip cont
[quote='810603021, AamirNezam, /thread/810603, /profile/AamirNezam'] we are facing an issue with the certificate validation [/quote] Can you provide more context here? Certificate validation is used in a lot of different places — Safair, networking APIs, code signing, push notifications, and so on — and so it’s not clear where I should route your question here on the Apple Developer Forums (or, indeed, whether it’d be better routed elsewhere, like Apple Support Community, run by Apple Support).

We package a nightly build of our application for distribution. About 1 month ago, this package has started showing the Apple could not verify 'Application' is free of malware message. This only happens to our development branch package. We run the same pipeline with the same signature for our stable branch and the stable package does not show this message. $ codesign -dv --verbose=4 KiCad.app Executable=/Applications/KiCad/KiCad/KiCad.app/Contents/MacOS/kicad Identifier=org.kicad.kicad Format=app bundle with Mach-O universal (x86_64 arm64) CodeDirectory v=20500 size=51931 flags=0x10000(runtime) hashes=1612+7 location=embedded VersionPlatform=1 VersionMin=722432 VersionSDK=983552 Hash type=sha256 size=32 CandidateCDHash sha256=4f15435c1d3cc056a83432b78a2f6acae8fb0e6d CandidateCDHashFull sha256=4f15435c1d3cc056a83432b78a2f6acae8fb0e6d03cbe70641719fd1ced3395b Hash choices=sha256 CMSDigest=4f15435c1d3cc056a83432b78a2f6acae8fb0e6d03cbe70641719fd1ced3395b CMSDigestType=2 Executable Segme
Hi, for Tap to Pay distribution, apple asked to submit an app review check list, in which there are merchant education questions. What does it mean by these questions, is apple asking us to show tutorials or help articles on the app or via company's help support website? Pls help as im not sure how to move forward.
Hi, I am modifying the sample camera app that is here: https://developer.apple.com/tutorials/sample-apps/capturingphotos-camerapreview ... In the processPreviewImages, I am using the Vision APIs to generate a segmentation mask for a person/object, then compositing that person onto a different background (with some other filtering). The filtering and compositing is done via CoreImage. At the end, I convert the CIImage to a CGImage then to a SwiftUI Image. When I run it on my iPhone, it works fine, and has not crashed. When I run it on the iPhone with the debugger, it crashes within a few seconds with: EXC_BAD_ACCESS in libRPAC.dylib`std::__1::__hash_table, std::__1::__unordered_map_hasher, std::__1::hash, std::__1::equal_to, true>, std::__1::__unordered_map_equal, std::__1::equal_to, std::__1::hash, true>, std::__1::allocator>>::__emplace_unique_key_args, std::__1::tuple<>>: It had previously been working fine with the debugger, so I'm not sure what has changed. Is there
We are seeing the same in a SwiftUI runtime. Completely new crash. What version are you running?

Hello, I am encountering the following error when uploading a build to App Store Connect: ITMS-90555: Thinned app size is too large – Your on-demand resources in the universal variant are 30 GB, which exceeds the maximum allowable size. After app thinning, the total size of your on-demand resource asset packs in any variant must be less than 30 GB. Our application includes a large amount of font resources delivered via ODR. Before making structural changes, I need clarification because the documentation does not fully explain how ODR size calculations work per variant. Environment Xcode: (latest stable) Distribution method: App Store submission ODR total size before thinning: approximately (28 GB) Build processing fails immediately with the ITMS-90555 error Questions How exactly does App Thinning compute the size of ODR asset packs per variant? Is ODR size evaluated: Per device-specific variant, Or is the “universal variant” treated as an additional variant that must independently stay under 30GB? The documen
We have an app in Swift that uses push notifications. It has a deployment target of iOS 15.0 I originally audited our app for iOS 26 by building it with Xcode 26 beta 3. At that point, all was well. Our implementation of application:didRegisterForRemoteNotificationsWithDeviceToken was called. But when rebuilding the app with beta 4, 5 and now 6, that function is no longer being called. I created a simple test case by creating a default iOS app project, then performing these additional steps: Set bundle ID to our app's ID Add the Push Notifications capability Add in application:didRegisterForRemoteNotificationsWithDeviceToken: with a print(HERE) just to set a breakpoint. Added the following code inside application:didFinishLaunchingWithOptions: along with setting a breakpoint on the registerForRemoteNotifications line: UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .alert, .sound]) { granted, _ in DispatchQueue.main.async { UIApplication.shared.registerForRemoteNotifications() } } Bu
I am not an Apple employee, but there's a good chance most of the Apple apps you mentioned use Mac Catalyst because they were originally written for iOS with UIKit. Porting a UIKit app using Mac Catalyst is going to be faster than writing a Mac version from scratch. I don't see the advantage of using Mac Catalyst for a new SwiftUI app project. SwiftUI supports both iOS and Mac so you can share a lot of the same code and provide a native Mac experience. If you don't want to provide a native Mac experience, you can avoid Mac Catalyst, make an iOS app, and let people with Apple Silicon Macs run the iPad version. I have never used Mac Catalyst so I can't tell you how mature it is.

Trying to develop a little Watch app in Swift, and it's been kind of a miserable experience. I constantly get transport errors trying to connect to my watch. I've tried the trick of putting the Mac and the watch on my iPhone hotspot instead of just on the same WiFi network, but I am not sure that actually helps. I can run maybe once or twice, and then the transport error happens and it's very hard to get XCode to recognize the watch again. Also, when it DOES connect, it seems that XCode almost always loses the debugging connection (I just continue, and it IS actually running on the Watch at that point, but no debugger).
It doesn't make much sense to make Statistics as an AppEntity as this is only computed as a result. You're spot on with that thought, which is why there's TransientAppEntity. There's even an example of generated statistics to show this API off in a sample code project — take a look at the ActivityStatisticsSummary structure in that project! — Ed Ford, DTS Engineer
