Hi everyone, I'm developing a visionOS app that allows users to download large video files (similar to a movie download experience, with each file being around 10 GB). I've successfully implemented the core video download functionality using URLSession, and everything works as expected while the app is active. Now, I’m looking to support background downloading. Specifically, I want users to be able to start a download and then leave the app (e.g., switch apps or return to the home screen) while the download continues in the background. Additionally, I’d like to confirm a specific scenario: If the user starts a download, then removes the headset (keeping the device turned on and connected to power), will the download continue in the background? Or does visionOS suspend the app or downloads in this case? I’m considering using a background URLSessionConfiguration (as done in iOS/macOS) to enable this behavior, but I’m not sure if it behaves the same way on visionOS or if there are special limitations or best practices when handling large downloads on this platform. Any insights or official guidance would be greatly appreciated! Thanks!

I am building an app that uses the SMAppService to register a LaunchDaemon that is bundled with my .app. I've got a priming flow created which walks the user through approving the service so that it will start on login. However, I need to also be able to upgrade this background service if the user updates the app. To do this, I think I need to call unregisterAndReturnError and then registerAndReturnError. From my testing, this seems to work correctly, but I have a concern. Will the user ever be prompted to re-authorize the LaunchDaemon that I am registering? If so, under what circumstances will that happen, and what does it look like (so that I can guide the user through it)?

We are encountering an issue where Apple Pay shows an unexpected popup with a message and an "OK" button when confirming a payment (after double-tapping the power button). This issue began appearing last week without any changes to the codebase or configurations. Steps to Reproduce: Open the app and initiate an Apple Pay payment. Add a valid card if not already present. Confirm the payment using the side button (double-tap). Instead of completing the transaction, a popup appears with a generic message and an "OK" button. Expected Behavior: Apple Pay should process the payment and provide a confirmation or error based on the transaction status. Actual Behavior: A popup appears with a generic title and an “OK” button. The transaction is not processed. Environment Details: Platform: iOS Apple Pay integration has been functioning correctly for years No recent updates to Apple Pay-related code or configuration Configurations Checked: App Identifier is correctly set with the bundle ID Apple Pay Payment Processing is enabled in the App ID configuration Correct Merchant ID is selected and matches in Xcode capabilities *.entitlements file contains correct Apple Pay entitlement Payment Processing Certificates are valid and in place Additional Notes: The issue appeared suddenly without any modifications to the app. We suspect it may be due to external changes (e.g., Apple system update or merchant validation issue). Please advise on any further steps we can take to diagnose or resolve this issue.

I have been playing with application bundled LaunchAgents: I downloaded Apple sample code, Run the sample code as is, Tweaked the sample code a lot and changed the LaunchAgents IDs and Mach ports IDs, Created new projects with the learnings, etc. After deleting all the Xcode projects and related project products and rebooting my machine several times, I noticed the LaunchAgent are still hanging around in launchctl. If I write launchctl print-disabled gui/$UID (or user/$UID) I can see all my testing service-ids: disabled services = { "com.xpc.example.agent" => disabled "io.dehesa.apple.app.agent" => disabled "io.dehesa.sample.app.agent" => disabled "io.dehesa.example.agent" => disabled "io.dehesa.swift.xpc.updater" => disabled "io.dehesa.swift.agent" => disabled } (there are more service-ids in that list, but I removed them for brevity purposes). I can enable or disable them with launchctl enable/disable service-target, but I cannot really do anything else because their app bundle and therefore PLIST definition are not there anymore. How can I completely remove them from my system? More worryingly, I noticed that if I try to create new projects with bundled LaunchAgents and try to reuse one of those service-ids, then the LaunchAgent will refuse to run (when it was running ok previously). The calls to SMAppService APIs such .agent(plistName:) and register() would work, though.

I have developed an podcast app, where subscriped podcast & episodes synched with iCloud. So its working fine with iOS & iPad with latest os version, but iCloud not synching in iPod with version 15. Please help me to fix this. Thanks Devendra K.

Hi folks, I'm building an iOS companion app to a local hosted server app (hosted on 0.0.0.0). The MacOS app locally connects to this server hosted, and I took the approach of advertising the server using a Daemon and BonjourwithTXT(for port) and then net service to resolve a local name. Unfortunately if there's not enough time given after the iPhone/iPad is plugged in (usb or ethernet), the app will cycle through attempts and disconnects many times before connecting and I'm trying to find a way to only connect when a viable en interface is available. I've run into a weird thing in which the en interface only becomes seen on the NWMonitor after multiple connection attempts have been made and failed. If I screen for en before connecting it simply never appears. Is there any way to handle this such that my app can intelligently wait for an en connection before trying to connect? Attaching my code although I have tried a few other setups but none has been perfect. func startMonitoringAndBrowse() { DebugLogger.shared.append("Starting Bonjour + Ethernet monitoring") if !browserStarted { let params = NWParameters.tcp params.includePeerToPeer = false params.requiredInterfaceType = .wiredEthernet browser = NWBrowser(for: .bonjourWithTXTRecord(type: "_mytcpapp._tcp", domain: nil), using: params) browser?.stateUpdateHandler = { state in if case .ready = state { DebugLogger.shared.append("Bonjour browser ready.") } } browser?.browseResultsChangedHandler = { results, _ in self.handleBrowseResults(results) } browser?.start(queue: .main) browserStarted = true } // Start monitoring for wired ethernet monitor = NWPathMonitor() monitor?.pathUpdateHandler = { path in let hasEthernet = path.availableInterfaces.contains { $0.type == .wiredEthernet } let ethernetInUse = path.usesInterfaceType(.wiredEthernet) DebugLogger.shared.append(""" NWPathMonitor: - Status: \(path.status) - Interfaces: \(path.availableInterfaces.map { "\($0.name)[\($0.type)]" }.joined(separator: ", ")) - Wired Ethernet: \(hasEthernet), In Use: \(ethernetInUse) """) self.tryToConnectIfReady() self.stopMonitoring() } monitor?.start(queue: monitorQueue) } // MARK: - Internal Logic private func handleBrowseResults(_ results: Set<NWBrowser.Result>) { guard !self.isResolving, !self.hasResolvedService else { return } for result in results { guard case let .bonjour(txtRecord) = result.metadata, let portString = txtRecord["actual_port"], let actualPort = Int(portString), case let .service(name, type, domain, _) = result.endpoint else { continue } DebugLogger.shared.append("Bonjour result — port: \(actualPort)") self.resolvedPort = actualPort self.isResolving = true self.resolveWithNetService(name: name, type: type, domain: domain) break } } private func resolveWithNetService(name: String, type: String, domain: String) { let netService = NetService(domain: domain, type: type, name: name) netService.delegate = self netService.includesPeerToPeer = false netService.resolve(withTimeout: 5.0) resolvingNetService = netService DebugLogger.shared.append("Resolving NetService: \(name).\(type)\(domain)") } private func tryToConnectIfReady() { guard hasResolvedService, let host = resolvedHost, let port = resolvedPort else { return } DebugLogger.shared.append("Attempting to connect: \(host):\(port)") discoveredIP = host discoveredPort = port connectionPublisher.send(.connecting(ip: host, port: port)) stopBrowsing() socketManager.connectToServer(ip: host, port: port) hasResolvedService = false } } // MARK: - NetServiceDelegate extension BonjourManager: NetServiceDelegate { func netServiceDidResolveAddress(_ sender: NetService) { guard let hostname = sender.hostName else { DebugLogger.shared.append("Resolved service with no hostname") return } DebugLogger.shared.append("Resolved NetService hostname: \(hostname)") resolvedHost = hostname isResolving = false hasResolvedService = true tryToConnectIfReady() } func netService(_ sender: NetService, didNotResolve errorDict: [String : NSNumber]) { DebugLogger.shared.append("NetService failed to resolve: \(errorDict)") } }

I am aware the USB / HID devices can come and go, if you have a long running application that's what you want to monitor. But for a "one-shot" command-line tool for example, I would like to enumerate the devices present on a system at a certain point in time, interact with a subset of them (and this interaction can fail since the device may have been disconnected in-between enumerating and me creating the HIDDeviceClient), and then exit the application. It seems that HIDDeviceManager only allows monitoring an Async[Throwing]Stream which provides the initial devices matching the query but then continues to deliver updates, and I have no idea when this initial list is done. I could sleep for a while and then cancel the stream and see what was received up to then, but that seems like the wrong way to go about this, if I just want to know "which devices are connected", so I can maybe list them in a "usage" or help screen. Am I missing something?

I created a new project, packaged it with my own enterprise certificate, installed and used it. There were no problems on most devices. However, on some devices with system versions of 18.3 and 18.4, the app crashes when opened after trusting the certificate. It seems that there is something wrong with the certificate, but I have confirmed that the certificate is fine. May I ask what the cause of this issue is?

As of 2025-05-03, when a macOS user enables iCloud Drive synchronization for Desktop & Documents in US region, does iCloud filter xattrs upon upload or later when downloading back to another macOS host? Or is it the case that iCloud has no filtering of third-party xattrs? Where can I find the technical document outlining exactly what iCloud does with xattrs set on macOS host files and folders synchronized with iCloud Drive?

As the title says. This happens even when not in dark mode.

Hi, I have some questions regarding the Background Assets Extension and DeviceCheck framework. Goal: Ensure that only users who have purchased the app can access the server's API without any user authentication using for example DeviceCheck framework and within a Background Assets Extension. My app relies on external assets, which I'm loading using the Background Assets Extension. I'm trying to determine if it's possible to obtain a challenge from the server and send a DeviceCheck assertion during this process within the Background Assets Extension. So far, I only receive session-wide authentication challenges—specifically NSURLAuthenticationMethodServerTrust in the Background Assets Extensio. I’ve tested with Basic Auth (NSURLAuthenticationMethodHTTPBasic) just for experimentation, but the delegate func backgroundDownload( _ download: BADownload, didReceive challenge: URLAuthenticationChallenge ) async -> (URLSession.AuthChallengeDisposition, URLCredential?) is never called with that authentication method. It seems task-specific challenges aren't coming through at all. Also, while the DCAppAttestService API appears to be available on macOS, DCAppAttestService.isSupported always returns false (in my testing), which suggests it's not actually supported on macOS. Can anyone confirm if that’s expected behavior?

Hello, I am trying to get space which is consumed by APFS volume. The call getattrlist() works fine on macOS 15 (Apple silicon). However, it returns EINVAL on macOS 11.7.10 (Intel) if ATTR_VOL_SPACEUSED is defined. struct VolAttrBuf { u_int32_t length; off_t spaceUsed; } __attribute__((aligned(4), packed)); int64_t GetVolumeSpaceUsed(const std::string& mountPath) { struct attrlist attrList; std::memset(&attrList, 0, sizeof(attrList)); attrList.bitmapcount = ATTR_BIT_MAP_COUNT; attrList.volattr = ATTR_VOL_INFO | ATTR_VOL_SPACEUSED; VolAttrBuf attrBuf; if (getattrlist(mountPath.c_str(), &attrList, &attrBuf, sizeof(attrBuf), 0) || attrBuf.length > sizeof(attrBuf)) { std::cout << "getattrlist() failed with errno (" << errno << ")" << std::endl; return -1; } return attrBuf.spaceUsed; } Is it bug or ATTR_VOL_SPACEUSED is unsupported on macOS 11? Are there any other way to get space which is used on an APFS volume? (C++) Thank you in advance, Pavel

I have an Expo React Native application and I am using react-native-iap library. I have setup the URL for sandbox and production url to receive notifications when a something happens regarding subscriptions. I am not able to receive those notifications when I simulate the purchase on the Simulator using Xcode. I then have used the node library app-store-server-library to mock a test notification and I am receiving the test notification when I call requestTestNotification method. below is the react-native code I am using: import {useEffect, useState} from "react"; import { initConnection, Sku, Subscription, useIAP, SubscriptionIOS, requestSubscription, PurchaseError, clearTransactionIOS } from "react-native-iap"; import styles from "@/screens/IAP/IAPStyles"; import CustomText from "@/components/CustomText"; import Heading from "@/components/Heading"; import subscriptionsProducts from "@/utilities/products"; function IAPScreen() { const [isPurchasing, setIsPurchasing] = useState<boolean>(false); const [loading, setLoading] = useState<boolean>(false); const { subscriptions, currentPurchase, finishTransaction, getSubscriptions } = useIAP(); function RenderProduct({ item } : { item: Subscription }) { const iosSubscription: SubscriptionIOS = item as SubscriptionIOS; return( <View style={styles.productCard}> <CustomText customStyles={styles.productTitle} text={iosSubscription.title} size={"medium"} /> <CustomText customStyles={styles.productDescription} text={iosSubscription.description} size={"small"} /> <CustomText customStyles={styles.productPrice} text={iosSubscription.localizedPrice} size={"small"} /> <Button title="Purchase" disabled={isPurchasing} onPress={ () => HandlePurchase(iosSubscription.productId) } /> </View> ); } async function HandlePurchase(sku: Sku) { try { setIsPurchasing(true); await requestSubscription({ sku, andDangerouslyFinishTransactionAutomaticallyIOS: false }); } catch (error: any) { Alert.alert("Error", "Failed to purchase: " + error.message); } finally { setIsPurchasing(false); } } useEffect(() => { setLoading(true); console.log(`[${new Date().toISOString()}] Initializing IAP connection...`); const setupIAP = async () => { try { const result = await initConnection(); console.log(`[${new Date().toISOString()}] IAP connection initialized:`, result); await clearTransactionIOS(); await getSubscriptions({ skus: subscriptionsProducts }); } catch (error: any) { Alert.alert("Error", "Failed to load products: " + error.message); } finally { setLoading(false); } }; setupIAP() .finally(() => setLoading(false)); }, []); useEffect(() => { const checkCurrentPurchase = async () => { try { if(currentPurchase?.productId) { console.log("Current purchase: ", currentPurchase); console.log("Transaction Id: ", currentPurchase.transactionId); await finishTransaction({ purchase: currentPurchase, isConsumable: false, }); } } catch (error) { if(error instanceof PurchaseError) { console.log("Purchase error: ", error); } else { Alert.alert("Error", "Failed to finish transaction: " + error); } } } if(currentPurchase) { console.log("Finishing current purchase."); checkCurrentPurchase() .catch(error => Alert.alert("Error", "Failed to finish transaction: " + error.message)); } }, [currentPurchase, finishTransaction]); return( <View style={styles.mainContainer}> <Heading text={"Packages & Subscriptions"} type={"h2"} customStyles={styles.header} /> { loading ? <ActivityIndicator size="large" /> : subscriptions.length > 0 ?

When I launch the Quick Look Preview Extension target in Xcode, an app called Quick Look Simulator opens with an almost empty window: Online I read that the Terminal command qlmanage allows to test Quick Look plugins (which I think were an older format for creating Quick Look extensions), but running qlmanage -p /path/to/previewed/file -c public.text -g /path/to/QuickLookPreviewExtension.appex (where QuickLookPreviewExtension.appex is generated by the Xcode build and is located in the DerivedData folder) gives an error Can't get generator at QuickLookPreviewExtension.appex How can I debug a Quick Look Preview Extension?

Guys has anyone here used the PlayVideoIntent protocol while implementing app intents? If yes can you please walk me though what purpose it solves and what features and functionality I can unlock with it?

I am developing an iOS app that uses CLLocationManager to collect location continuously in both foreground and background. But it has the following 4 issues and I don’t understand why: After a while of not using the app, I can not get location updates regularly. Even after that, I go into the app more often or even turn OFF and turn ON the permission again, but the problem still doesn’t improve until I reinstall the app. Previously, I used SilentLog SDK to collect location. Since the cost was quite high, we developed our own SDK that also handles location tracking. After updating the app from the old version using SilentLog SDK to the new version using my own SDK, I can not get location updates regularly. However, when I reinstalled the app, it worked perfectly. It seems that apps downloaded from TestFlight can get location more continuously than apps downloaded from the App Store We sometimes encounter this error in the logs: Error Domain=kCLErrorDomain Code=0 “(null)” I think my app was not terminated in the background because I still collect location but it is not as frequent. I want to know if Apple has any mechanism to prevent such apps from getting location data continuously? I use CLLocationManager with the following configuration: self.locationManager.distanceFilter = 20 self.locationManager.desiredAccuracy = kCLLocationAccuracyBest self.locationManager.allowsBackgroundLocationUpdates = true self.locationManager.showsBackgroundLocationIndicator = false self.locationManager.pausesLocationUpdatesAutomatically = false I also filter the location updates using: guard let location = locations.last else { return } guard location.horizontalAccuracy <= 100 else { return } guard location.speedAccuracy >= 0 else { return } I use a background task to wake up the device every 15 minutes, and I also use silent push notifications in a similar manner. Each time the task is executed, I usually call stopLocation and then startLocation again. This happens quite frequently — will it have any impact or cause any issues?
