MacOS 26 TestFlight SIGKILLs app when updating
We're developing an Electron app for MacOS App Store. When updating our app through TestFlight, TestFlight prompts "Close This App to Update", and when I click "Continue" our app would be "Terminated" for update. Now this is where things go wrong. On MacOS 15 our app seems to be gracefully terminating (We attached it with lldb and it shows that our app returns with 0 when we click "Continue") which is fine. However for MacOS 26 though, it seems that TestFlight just directly SIGKILLs our app (indicated by lldb), which means that all of our app's child processes are left orphaned. Even worse, our app is singleton, which means that when the app relaunches it fails, because the leftover child processes from the previously SIGKILLed session is still alive, and even if we want to kill those orphaned child processes we can't because our app is sandboxed thus cannot kill processes outside of the current sandbox. We captured output from log stream (app name redacted): 12-02 22:08:16.477036-0800 0x5452     Default     0x5a4a7              677    7    installcoordinationd: [com.apple.installcoordination:daemon] -[IXSCoordinatorProgress setTotalUnitsCompleted:]: Progress for coordinator: [com.our.app/Invalid/[user-defined//Applications/OurApp.app]], Phase: IXCoordinatorProgressPhaseLoading, Percentage: 99.454 123: Attempt to set units completed on finished progress: 214095161 2025-12-02 22:08:16.483056-0800 0x53ba     Default     0x5a5c9              167    0    runningboardd: (RunningBoard) [com.apple.runningboard:connection] Received termination request from [osservice<com.apple.installcoordinationd(274)>:677] on <RBSProcessPredicate <RBSProcessBundleIdentifierPredicate "com.our.app">> with context <RBSTerminateContext| explanation:installcoordinationd app:[com.our.app/Invalid/[user-defined//Applications/OurApp.app]] uuid:A3BC0629-124E-4165-ABB7-1324380FC354 isPlaceholder:N re portType:None maxTerminationResistance:Absolute attrs:[ 2025-12-02 22:08:16.488651-0800 0x53ba     Default     0x5a5c9              167    7    runningboardd: (RunningBoard) [com.apple.runningboard:ttl] Acquiring assertion targeting system from originator [osservice<com.apple.installcoordinationd(274)>:677] with description <RBSAssertionDescriptor| "installcoordinationd app:[com.our.app/Invalid/[user-defined//Applications/OurApp.app]] uuid:A3BC0629-124E-4165-ABB7-1324380FC354 isPlaceholder:N" ID:167-677-1463 target:system attributes:[ 2025-12-02 22:08:16.489353-0800 0x53ba     Default     0x5a5c9              167    0    runningboardd: (RunningBoard) [com.apple.runningboard:process] [app<application.com.our.app.485547.485561(501)>:2470] Terminating with context: <RBSTerminateContext| explanation:installcoordinationd app:[com.our.app/Invalid/[user-defined//Applications/OurApp.app]] uuid:A3BC0629-124E-4165-ABB7-1324380FC354 isPlaceholder:N reportType:None maxTerminationResistance:Absolute attrs:[ 2025-12-02 22:10:23.920869-0800 0x5a5a     Default     0x5a4c6              674    14   appstoreagent: [com.apple.appstored:Library] [A95D57D7] Completed with 1 result: <ASDApp: 0xc932a8780>: {bundleID = com.our.app; completedUnitCount = 600; path = /Applications/OurApp.app; installed = 0} 2025-12-02 22:10:32.027304-0800 0x5ae5     Default     0x5a4c7              674    14   appstoreagent: [com.apple.appstored:Library] [BEB5F2FD] Completed with 1 result: <ASDApp: 0xc932a8780>: {bundleID = com.our.app; completedUnitCount = 600; path = /Applications/OurApp.app; installed = 0} 2025-12-02 22:10:36.542321-0800 0x5b81     Default     0x5a4c8              674    14   appstoreagent: [com.apple.appstored:Library] [185B9DD6] Completed with 1 result: <ASDApp: 0xc932a8780>: {bundleID = com.our.app; completedUnitCount = 600; path = /Applications/OurApp.app; installed = 0} The line "Terminating with context" seems suspicious. This line is not seen on MacOS 15, only MacOS 26. Is this documented behavior? If so, how can we handle this?

Core Bluetooth Advertising in Background
Hello guys, I have been trying to advertise in the background but I can’t seem to make it work. In my case, I want if a device is acting as a peripheral and the app goes to the background it still can be discoverable and be able to write/read to/from it by the central. I have added the background mode “Acts as a Bluetooth accessory”. When will willRestoreState be called? What should I do in willRestoreState? Will it always be discoverable or have some limitations? Should I stop advertising at any point? How should I clean up after the view is dismissed? Must the peripheral manager be initialized in the AppDelegate? and if so, will it always be advertising even if I don't want it to? What are the battery concerns? Also, I have encountered an issue that my iPhone device can discover an Android device but not the opposite. What could be the problem of this? Thank you. Best regards

Z-Index for MarkerAnnotation
Hey there, is there a way to set the z-index for MarkerAnnotations in MapkitJS? I'm loading up to 200 markers dynamically as the map moves or the user zooms and I want a few specific markers to always be at the top (the best search results). The only way I found is to always remove all markers and then add them again in the right order, but that's visually so annoying to see them disappear and animate in with every tiny movement. I thought about using a default Annotation and setting the z-index myself and trying to rebuild the balloon, including the animation when it's clicked, but the big downside is probably the performance because I won't be able to use shadow DOM elements and have 200 real DOM elements instead. Is there a solution to this right now or is it planned to add a feature like that to Mapkit JS? It's a real blocker for me right now because all the bad content always gets rendered on top when a user zooms in, because I obviously want to show the best content first when the user isn't zoomed in yet. Thank you so much in advance. I really appreciate it. Manuel

Double-counted consumable in StoreKit unfinished and updates workflow
In Getting started with In-App Purchase using StoreKit views and the corresponding sample project, Store simultaneously enumerates Transaction.unfinished and Transaction.updates. Since, "if your app has unfinished transactions, the updates listener receives them once, immediately after the app launches," it appears that Transaction.unfinished would also receive the same unfinished transactions causing handle(updatedTransaction:) to be called for twice for each transaction, causing consumables to be double-counted. Is this a bug in the sample? Is there more information on concurrent execution of unfinished and updates?

Once started, NWPathMonitor appears to be kept alive until cancelled, but is this documented?
NWPathMonitor appears to retain itself (or is retained by some internal infrastructure) once it has been started until cancelled. This seems like it can lead to memory leaks if the references to to the monitor are dropped. Is this behavior documented anywhere? func nwpm_self_retain() { weak var weakRef: NWPathMonitor? autoreleasepool { let monitor: NWPathMonitor = NWPathMonitor() weakRef = monitor monitor.start(queue: .main) // monitor.cancel() // assertion fails unless this is called } assert(weakRef == nil) } nwpm_self_retain()

Why my App Clip Card can not be opened?
Hello, I have an AppClip technical issue I'd like to ask about: Our Xiaohongshu App (Version 9.14 & Build 9140845 & appid 741292507) was submitted to the App Store for review on December 18th and approved on December 19th, starting a phased rollout. This version was the first to support AppClip functionality, and as of today the app has been fully rolled out, but I still cannot activate the Xiaohongshu App Clip Card using the NFC tag (built-in URL: https://xhslink.com/n/22UG9jlaOfv?sourceid=911). I checked all the configurations of our project's AppClip target (Associated Domains:appclips:xhslink.com), the default experience in the ASC backend (URL: https://appclip.apple.com/id?p=com.xingin.discover.Clip), and the advanced experience (URL: https://xhslink.com/n/Arxpo4IVY9X), and all showed no abnormalities. Furthermore, the default experience URL, after being written with an NFC tag, can be successfully launched by tapping the NFC tag to open the Xiaohongshu App Clip Card, and the Card can also be opened normally in Safari on the phone. However, our advanced experience URL, after being written with an NFC tag, cannot be launched by tapping the Card. Therefore, my question is: Who please can help me check why the Xiaohongshu App Clip Card cannot be launched normally using the advanced experience URL? Thank you very much! My Expectations: My advanced experience URL configured on the ASC platform, such as https://xhslink.com/n/Arxpo4IVY9X, should be recognized and validated by the iOS system when the phone is near the NFC tag and reads https://xhslink.com/n/22UG9jlaOfv?sourceid=911, ultimately triggering the App Clip Card configured in Xiaohongshu's advanced experience settings. Additionally: We have already deployed a large number of NFC tags and other materials in many online stores, and the URL (https://xhslink.com/n/Arxpo4IVY9X) is built-in, and our 9.14 version is fully implemented. However, the newly developed App Clip feature is not working, which is very urgent and I hope Apple can help me find the cause of the problem and how to improve it as soon as possible. Thank you very much!

How to distinguish which operations in the file provider are during offline period
Currently tested, if the file provider goes offline (referring to calling disconnect) and deletes a file, the system will automatically trigger the deleteItems event after reconnecting (note that only after calling reconnect again will the current deleteItems logic be reached). However, for offline deletion, I would like to pass it directly without operating on the cloud. Can mounting disks determine which operations were performed offline during reboot

Howti populate Finder comment from NSFileProviderItemProtocol extendedAttributes
I am trying to populate the Finder comment field from extendedAttributes with the code bellow but it doesn't work. Any idea why ? var extendedAttributes: [String : Data] { var attrs = [String: Data]() let comment = self.caption do { let xmlPlistData = try PropertyListSerialization.data(fromPropertyList: comment as Any, format: .xml, options: 0) attrs["com.apple.metadata:kMDItemFinderComment"] = xmlPlistData } catch { NSLog("Error during plist conversion: \(error)") } return attrs }

CBCentralManager State Changes to PoweredOff After Using ASK for Accessory Setup
We are observing some unexpected behavior in our app when using ASK. Our app is able to successfully discover and set up an accessory via ASK. After the setup completes, the connection to the accessory is managed through CBCentralManager and works as expected. However, when we attempt to discover another accessory afterward, the picker is shown and indicates that accessory discovery is in progress. After approximately 10 seconds, the CBCentralManager delegate reports the Bluetooth state as poweredOff. Once this happens, the state never transitions back to poweredOn. At this point, the only way to reconnect to the device or continue discovery is to relaunch the app. We are wondering if anyone else has encountered similar behavior, or if this is a known or documented limitation/behavior when using ASK in combination with CBCentralManager.

AccessorySetupKit documentation
This is not a question but rather a small bit of documentation on how Accessory Setup Kit actually works. I spent a couple days figuring this out so I thought let's share my findings. The example app is very light and the documentation definitely has room for improvement so here are a couple important notes. Findings: If you're running > iOS 18 and add any property to your Info.plist file you're no longer able to scan for devices by using CBCentralManager.scanForPeriphals. This will no longer return discoverable devices. Below iOS 18 these properties in the Info.plist are ignored by the OS and you can safely use the "legacy" method of connecting to bluetooth devices. If you're running > iOS 26 the removeAccessory will show a prompt to the user. If you're running < 26 you can silently remove the accessory and start each session with a clean state. If you create CBCentralManager before you start the ASK session you'll not get the state = PoweredOn. If you have 0 accessories connected to your application CBCentralManager will never enter the state = PoweredOn when you create the CBCentralManager. Pre-ASK this would be the trigger for iOS to ask the user permission. This is no longer necessary with ASK. If you have have 1 or more accessories authorized to your app this will be returned in the session.accessories after the session has started. This is an important indicator to determine app behavior. If you have 1 or more accessories CBCentralManager.scanForPeripherals will ONLY return previously authorized AND discoverable devices. Use this for when you want to connect to a previously authorized device. If you have 1 or more accessories and the CBCentralManager.scanForPeripherals returns nothing you can (safely) assume the user attempts to onboard a new device. So for my application I take the following steps: Check for iOS version, if > iOS 18 start ASK session. Are there previously authorized devices? -- yes: run CBCentralManger.scanForPeripherals -- no: show the picker Did the scan return any devices? -- yes: show UI to select device or connect with first available device in the list -- no: show the picker Feel free to add any of your findings and @Apple please update the documentation!

SKTestSession.setSimulatedError() not working for .loadProducts API in iOS 26.2
Description SKTestSession.setSimulatedError() does not throw the configured error when testing StoreKit with the .loadProducts API in iOS 26.2. The simulated error is ignored, and products load successfully instead. Environment iOS: 26.2 (Simulator) Xcode: 26.2 beta 2 (Build 17C5038g) macOS: 15.6.1 Framework: StoreKitTest Testing Framework: Swift Testing base project: https://developer.apple.com/documentation/StoreKit/implementing-a-store-in-your-app-using-the-storekit-api Expected Behavior After calling session.setSimulatedError(.generic(.notAvailableInStorefront), forAPI: .loadProducts), the subsequent call to Product.products(for:) should throw StoreKitError.notAvailableInStorefront. Actual Behavior The error is not thrown. Products load successfully as if setSimulatedError() was never called. Steps to Reproduce Create an SKTestSession with a StoreKit configuration file Call session.setSimulatedError(.generic(.notAvailableInStorefront), forAPI: .loadProducts) Call Product.products(for:) with a valid product ID Observe that no error is thrown and the product loads successfully Sample Code import StoreKitTest import Testing struct SKDemoTests { let productID: String = "plus.standard" @Test func testSimulatedErrorForLoadProducts() async throws { let storeKitConfigURL = try Self.getStoreKitConfigurationURL() let session = try SKTestSession(contentsOf: storeKitConfigURL) try await session.setSimulatedError( .generic(.notAvailableInStorefront), forAPI: .loadProducts ) try await confirmation("StoreKitError throw") { throwStoreKitError in do { _ = try await Self.execute(productID: productID) } catch let error as StoreKitError { guard case StoreKitError.notAvailableInStorefront = error else { throw error } throwStoreKitError() } catch { Issue.record( "Expect StoreKitError. Error: \(error.localizedDescription)" ) } } #expect(session.allTransactions().isEmpty) } static func execute(productID: String) async throws { guard let product = try await Product.products(for: [productID]).first( where: { $0.id == productID }) else { throw NSError( domain: "SKDemoTests", code: 404, userInfo: [NSLocalizedDescriptionKey: "Product not found for ID: \(productID)"] ) } _ = product } static func getStoreKitConfigurationURL() throws -> URL { guard let bundle = Bundle(identifier: "your.bundle.identifier"), let url = bundle.url(forResource: "Products", withExtension: "storekit") else { fatalError("StoreKit configuration not found") } return url } } Test Result The test fails because the expected StoreKitError.notAvailableInStorefront is never thrown. Question Is this a known issue in iOS 26.2 / Xcode 26.2 beta 2, or is there a different approach required for simulating errors with SKTestSession in this version? Any guidance would be appreciated.

Git and iCloud
Hi guys, also those at Apple, I love what you all do and make, long time Linux user switched since silicon. But is there perhaps any timeline on improving the interaction between iCloud and git? Perhaps it is on me to check beforehand, but I enabled Desktop & Doc sync on iCloud (which included some git repos) and these now malfunction completely. Bad object errors, lost wheels, insanely long syncing, and worst of all - randomly removed environment variables! I only noticed when random stuff stopped working out of the blue; only after re-configuring zsh and doing scorched earth on brew did it click. I mean, there is a '.nosync' flaggy thing to add to dirs, but it isn't even officially supported. Moreover, when trying to disable sync for docs, it will delete local repos! So either it's disabling and starting all over again, or waiting for the sync to finish (which breaks things) and going through a long restoration process. I don't expect iCloud for the average Joe to be super specced for developers, but perhaps there could be room for some minor improvements that would at least prevent git repositories from completely breaking, e.g. just ignoring them or not syncing certain folder/file types. Restoring the whole thing (if even possible) is an extremely long and tedious process. Sorry for the rant, but I feel this might be appreciated. One of the things I like about this ecosystem, proprietary it is, is the seemliness and easy of use. If iCloud Drive is advertised as 'it will work', it's only fair that this would apply to developers too (and that they are not required to check beforehand whether it will break all of their git repositories). Or it is just me getting old. :) Cheers, Frans

Problem installing a third-party app
I have a third-party app installed on my iPhone 16 Pro Max, and since yesterday I've been getting the following error: "An internet connection is required to verify developer trust. Apple Development: Created via API (3GJ3LH6NRW). This app will not be available until it has been verified." Can you help me fix this? I've been told it should work again on its own in 2 to 4 days. I have a Developer account to sign apps and avoid problems; it's never given me any trouble until now.

How to get displayName actually used by Finder when using FileProvider API
I am developing a FileProvider extension which will be launched for one or more domains. In the case where I have two domains, say with displayNames "Foo" and "Bar", the finder will then show "MyExtension - Foo" and "MyExtension - Bar" respectively after registering them with addDomain. However, if I only have a single domain, let's say "Foo" – then I just see "MyExtension" rather than "MyExtension - Foo". Now ideally I'd like to be able to control the entire name, but barring that at least be able to show the displayName even with a single domain. How can I achieve that?

Unable to apply default decoration Icons to files and folders
Hello Everyone, I'm trying to add badges to files in my File Provider Extension for macOS. I'm not trying to create my own Item decorations here, but use the default Icons provided by apple (such as com.apple.icon-decoration.badge.heart , com.apple.icon-decoration.badge.pinned). I've gone through the Sample code provided by Apple for Fruit Basket. I've tried to replicate the same thing in my Extension as well but It seems I'm unable to display Icons. I'm not even getting any Error when the Icons are not being displayed, So I've been stuck for a month on this. These are the Things that I've done below: Folder Structure : FileExplorer |- FileProviderApp | |- UI.swift | |- ContentView.swift |- Extension |- extension.swift |- item.swift |- enumerator.swift |- info.plist According to the instructions given in the Documentation for Decorations here : https://developer.apple.com/documentation/fileprovider/nsfileprovideritemdecorating. The implementation was done as follows: content inside info.plist of the File provider Extension <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>NSExtension</key> <dict> <key>NSExtensionFileProviderSupportsEnumeration</key> <true/> <key>NSExtensionPointIdentifier</key> <string>com.apple.fileprovider-nonui</string> <key>NSExtensionPrincipalClass</key> <string>$(PRODUCT_MODULE_NAME).FileProviderExtension</string> <key>NSFileProviderDecorations</key> <array> <dict> <key>BadgeImageType</key> <string>com.apple.icon-decoration.badge.heart</string> <key>Category</key> <string>Badge</string> <key>Identifier</key> <string>$(PRODUCT_BUNDLE_IDENTIFIER).heart</string> <key>Label</key> <string>Heart Item</string> </dict> </array> </dict> </dict> </plist> In my extension's NSFileProviderItem I've also Implemented the protocol NSFileProviderItemDecorating. and the decoration's method as static let decorationPrefix = Bundle.main.bundleIdentifier! static let heartDecoration = NSFileProviderItemDecorationIdentifier(rawValue: "\(decorationPrefix).heart") var decorations: [NSFileProviderItemDecorationIdentifier]? { var decos = [NSFileProviderItemDecorationIdentifier]() decos.append(Item.heartDecoration) return decos } I was expecting to see badges on the File items in Finder, but i got nothing. When I modified the FruitBasket Project to do the same i was able to see badges, but not when I try to implement it in my Extension. Was I missing a step or is the issue something else ?
