I am the developer of MIDIDeviceManager, an iOS and iPadOS application used by musicians to control external MIDI hardware during live performance. Before enabling any background execution mode, I would like to ask which architecture Apple intends for this type of application. What the application does The app organises the patches of a musician's MIDI instruments into Pads, Scenes and Setlists so they can be recalled during a performance. It sends MIDI to external hardware such as guitar processors, synthesisers and vocal processors, and it also receives incoming MIDI that triggers its own Scenes — typically from a Bluetooth foot controller, a wired MIDI controller, or another app on the same device. Its purpose is to function as the software equivalent of a programmable hardware MIDI controller. It is not a lyrics app or an audio player, and it produces no audio. The problem During a performance, musicians commonly run more than one app. A typical setup is lyrics or chord charts displayed in one app while a Bluetooth foot controller recalls presets on a Line 6 Helix through MIDIDeviceManager. This requires the app to keep receiving and processing incoming CoreMIDI events while another app is frontmost. Once iOS suspends the app, those events are no longer delivered and the foot controller stops working. This affects iPhone as much as iPad. Several of my TestFlight users perform with iPhone alone, where the device sits on a stand and is not touched during a song. What I have observed I tested this directly on an iPhone 17 Pro Max. With two apps running simultaneously, an app legitimately using the audio background mode continued to receive and act on incoming CoreMIDI events from a Bluetooth foot controller while backgrounded. At the same moment, MIDIDeviceManager received nothing once iOS suspended it. This suggests that, under certain circumstances, an app executing under an appropriate background mode may continue receiving CoreMIDI while backgrounded. Background modes considered audio — appears to provide the required behaviour, but my app produces no audio output. I do not wish to declare a background capability that does not accurately describe what the app does. bluetooth-central — does not appear applicable, since Bluetooth MIDI connections are established through CoreMIDI and managed by the system MIDI server rather than by my own Core Bluetooth session. I have not been able to identify any mode intended for continuous MIDI reception, so UIBackgroundModes is currently empty. A previous rejection An earlier submission did declare audio, and was rejected under Guideline 2.5.4 on 7 July 2026 (submission ID eab58179-8177-4d05-9c37-5e1006828a96): "The app declares support for audio in the UIBackgroundModes key in the Info.plist but we are unable to locate any features that require persistent audio. Background audio is intended for use by apps that provide audible content to the user while in the background, such as music player, music creation, or streaming audio apps." That assessment is correct — the app produces no audio, and I removed the key. But the functional requirement remains: the app needs to receive MIDI while another app is frontmost. I am asking here rather than resubmitting, because I would rather understand the intended architecture than guess again. My questions Which background mode, if any, is appropriate for an app whose purpose is to continue receiving and processing incoming CoreMIDI events while another app is frontmost? If background MIDI reception is supported, is CoreMIDI expected to continue delivering incoming MIDI to a backgrounded app, or is there a different recommended architecture for apps of this type? If the answer is that no background mode applies and this capability is not available to apps of this kind, I would very much appreciate knowing that clearly. I can then document the limitation for my users and design accordingly rather than pursue an unsupported approach. My objective is not to find a workaround, but to implement this the way Apple intends professional MIDI applications to work. Thank you.

ご指定の挨拶や結びの言葉をすべて除外した、本文のみの英文です。 I am writing to inquire about the debugging workflow for background processing in recent versions of Xcode. In previous versions of Xcode, we were able to test the behavior of background fetches using the "Simulate Background Fetch" option under the Debug menu. However, this menu item is no longer available in the latest Xcode environment. Our application requires executing background tasks, such as automatically transferring images captured during background transition to a remote server. We are currently in the process of migrating our background structure to the latest BackgroundTasks framework (BGTaskScheduler) in accordance with the recommendations in the official documentation. Now that the GUI menu item has been removed, could you please provide the official guidelines or recommended workflow for simulating and debugging BGAppRefreshTask and BGProcessingTask on the iOS Simulator? Specifically, I would like to know if executing specific LLDB commands while the process is paused is the only supported method to simulate these events during development.

When adopting the Scene Delegate, the applicationState changes from indicating app state to indicating scene state. I previously used this as a signal to determine whether my iOS app was launched in the background or launched by the user. Given the change, it seems like applicationState should no longer be used in that manner in the App Delegate. Would you recommend using UIApplication.shared.backgroundTimeRemaining to distinguish a background launch from a user launch? assuming this is a very large value for user launches. Are there corner cases that I may not expect?

hello, i have an issue spawning continued background processing tasks: they are never started, even after restarting the device, regardless of which app spawns a task. deleting and reinstalling an app, or installing a new app that didn't exist before also does not work. it can be reproduced by setting your device local time to one year in advance and then trying to spawn the task. the task will not start and even after returning to the proper date, all apps on the device are still unable to spawn any. i also believe there are other things that trigger this issue (or something related), as many of my users have complained about tasks not starting. prior to my changing the date of my device, they worked perfectly for me. one user changed their date to test at the same time as me and the only fix they found was erasing their device and restoring a backup. on ios 26 tasks fail silently, but on ios 27 with the new api to submit a task, an error is caught: Error Domain=BGTaskSchedulerErrorDomain Code=1 "connection to service with pid 94 named com.apple.duetactivityscheduler" UserInfo={NSDebugDescription=connection to service with pid 94 named com.apple.duetactivityscheduler} in addition, a more detailed error with a stack trace is logged at the same time: <NSXPCConnection: 0x10c60c0a0> connection to service with pid 94 named com.apple.duetactivityscheduler: Exception caught during decoding of reply to message 'submitTaskRequest:withHandler:', dropping incoming message and calling failure block.

I want to use features described in the background assets WWDC22 session (https://developer.apple.com/videos/play/wwdc2022/110403/). In earlier versions of Xcode 14 beta there used to be a background asset extension target type, however this got removed in beta 5 and has still not been put back even though Xcode 14 RC is released. With Xcode 14 beta 4, if the background asset target was chosen then a bunch of template code was created, same as happens with any extension type. But if the background asset extension target type isn't even present in the Xcode 14 RC, how is one supposed to create an extension and use this new feature?

I have a Flutter project that uploads files in background mode, implemented as a plugin for the iOS part. It works fine in debug mode when running from Xcode, but no files are uploaded in release mode (installed via .ipa). I implemented functions such as BGAppRefreshTask and BGProcessingTask, and configured BGTaskSchedulerErrorCodeNotPermitted properly in Info.plist. I registered background tasks (processing and fetch), and BGTaskScheduler also works well. The issue is that it works fine in debug mode but not in release mode. Do I need to modify some settings in the .entitlements file or configure something else? Environment: macOS: Sequoia 15.7.7 Xcode: 26.3 Flutter SDK: 3.19.5

We are developing a system consisting of two iOS apps from the same developer (same Team ID): ・App A acquires data from an external accessory. For regulatory/compliance reasons that we cannot detail here, App A must have no networking capability at all. ・App B is intended to receive data from App A and upload it to a server. Two important environmental constraints: ・The deployment environment is a closed local network. The server App B talks to is on the local network, and Internet access is not guaranteed. Therefore, any APNs-dependent approach (silent push, etc.) is not viable. ・Latency requirement: near-real-time is ideal, but a delay of up to a few minutes is acceptable. What we have considered: 1.App Groups shared container — App A can write data, but there is no way to wake App B in the background when new data is written. 2.URL schemes — can launch App B reliably, but bring it to the foreground, which disrupts the user's workflow. 3.BGTaskScheduler — rejected; execution timing is entirely at the system's discretion. 4.Silent push — rejected; requires APNs / Internet connectivity, which we cannot assume (see above). Our current leading candidate is a combination of (1) and (2): App A writes data to the App Groups container, then opens App B via a URL scheme; App B reads the container and uploads. This works, but the foreground app switch on every hand-off is far from ideal. We are aware that some apps abuse background modes (e.g., playing silent audio) to stay resident. We assume this violates App Review Guideline 2.5.4 and is not an option for us — please correct us if there is any legitimate variant of this approach. Questions: 1.Is there any supported mechanism to keep App B running (or reliably woken) in the background, so that it can receive data from App A and upload it — without user interaction and without Internet access? 2.If not, is there any way to mitigate the foreground switch in our current App Groups + URL scheme approach (e.g., returning to App A automatically after the hand-off)? Or would that ping-pong pattern itself be an App Review concern? Any guidance would be appreciated.

Short version, in case it saves someone the trip I just took: if your app plays audio AND uses a background URLSession with sessionSendsLaunchEvents = true, playback can be killed mid-episode the moment you call the handleEventsForBackgroundURLSession completion handler, but only in a process that was launched into the background and never went foreground. There is no crash log and no jetsam event: applicationWillTerminate simply fires. To users it looks exactly like the app crashed while playing, which is how it was reported to me, and why I wasted a while looking for a crash that did not exist. My setup: podcast app, audio background mode a background URLSession (sessionSendsLaunchEvents = true, isDiscretionary = false) used only to refresh RSS feeds those feed downloads are started from a BGAppRefreshTask What happens: iOS launches the app into the background to run a BGAppRefreshTask. The scene connects unattached; the process never becomes foreground. The task starts a batch of feed downloads on the background session. They outlive the ~10 s refresh window and finish about two minutes later. Meanwhile the user presses Play on their AirPods. Playback starts, inside that same never-foreground process. The downloads finish. iOS calls handleEventsForBackgroundURLSession. I store the handler and invoke it on the main thread from urlSessionDidFinishEvents, as documented. ~1 ms later applicationWillTerminate fires and the audio stops. At that moment the app is playing audio: AVAudioSession active, category .playback, and -[UIApplication backgroundTimeRemaining] returning greatestFiniteMagnitude. A sysdiagnose shows audiomxd holding a MediaPlayback isPlayingProcessAssertion for the process, taken 27 s earlier, invalidated only as part of the teardown, and CMSessionMgr logging "pid ... is now Terminated. Background entitlement: YES" while IsPlayingOutput:YES. The tell, and the thing that took me longest to spot: if the process HAS been foreground at some point in its life, calling the identical completion handler on the identical session does not kill it, and playback carries on. Across a full day of logs, "has this process ever been foreground" is the only variable that predicts the kill. The audio background mode is not the problem, the app happily played for ~6 minutes as a never-foreground process on another occasion, and died only at the completion-handler call. Half of this is documented behaviour: the system takes a power assertion when it resumes you for the session, and calling the completion handler releases it. What I did not expect is that the audio assertion does not take over at that point. My workaround so far is sessionSendsLaunchEvents = false on the feed session. RSS refreshes are not urgent: the transfers still run in the background, and the system hands the results to me at the next launch, where my refresh task parses them. I'm still verifying if this works as expected. So, questions for anyone who has been here: Has anyone else with an audio app hit this? I have a hunch it shows up in the wild as unexplained "the app crashed while playing" reports, particularly for podcast and audiobook apps that refresh content in the background, because there is no crash log to point at. If you combine background audio with a background URLSession, how do you handle it? Do you avoid launch events entirely, or split urgent from non-urgent transfers across separate sessions? Is there a better pattern than turning launch events off for transfers that genuinely are not urgent? Filed as FB23789310 with a sysdiagnose and a timestamped log excerpt. If you have seen this too, a dupe would help.

Hello everyone, We have a feature in our iOS app called "automatic background sync", which syncs data between the mobile app and our backend periodically. It is specifically designed to work when the app is in a backgrounded state. We use both silent remote notifications that are sent from our backend periodically (using Firebase Cloud Messaging), and also BGAppRefresh task. The sync process should be as reliable as possible and work continuously while the app is in the background, even if the user does not open the app for a long period of time. We enforce a 20 second deadline to call the completion handler to match the 30 second limit. We have a specific customer that has multiple where the background sync does not work properly: One of them has continuous syncs for about a week, then it stops until the user opens (moves to foreground) the app again. Another user only has a sync when they open the app, then it stops when it is backgrounded. Looking at their logs: The app remains in the background and is rarely being actively killed, and it likely is not the reason that the user stopped receiving syncs. Their background app refresh setting in iOS settings is enabled. Both user's app stopped waking up and doing the task either from silent remote notifications or background tasks. Thank you!

I would love to use Background GPU Access to do some video processing in the background. However the documentation of BGContinuedProcessingTaskRequest.Resources.gpu clearly states: Not all devices support background GPU use. For more information, see Performing long-running tasks on iOS and iPadOS. Is there a list available of currently released devices that do (or don't) support GPU background usage? That would help to understand what part of our user base can use this feature. (And what hardware we need to test this on as developers.) For example it seems that it isn't supported on an iPad Pro M1 with the current iOS 26 beta. The simulators also seem to not support the background GPU resource. So would be great to understand what hardware is capable of using this feature!

Hello, I am implementing background processing using Silent Push Notifications in an iOS application. The app needs to receive requests from a server and execute processing in the background. For this purpose, I am using Silent Push Notifications to wake up the application. However, the application is not being launched as expected when running the TestFlight version. I would appreciate any guidance regarding this behavior. Environment Xcode 26.3 iOS 18.6 TestFlight distribution Push Notifications capability enabled Background Modes enabled Remote notifications enabled APNs Authentication Key (.p8) APNs Production environment Background Previously, the application periodically connected to a server in the background and sent location information when requested by the server. Since that background processing no longer behaves as expected, I started implementing an alternative approach using Silent Push Notifications. When running the application directly from Xcode in Debug mode, Silent Push works correctly and the app is launched in the background. However, when using the TestFlight build on the same device, the behavior differs and the app is not launched in the background. Observed Behavior The APNs request appears to be successful: APNs response status is HTTP 200 Using the device token obtained from the TestFlight build Alert Push notifications are received successfully application:didReceiveRemoteNotification:fetchCompletionHandler: is called when the app is in the foreground The same method is not called when the app is in the background Silent Push payload: { "aps": { "content-available": 1 } } HTTP/2 headers: apns-push-type: background apns-priority: 5 Verified Items Production device token is being used APNs topic matches the application's bundle identifier Alert Push notifications work correctly Background App Refresh is enabled on the device The application has not been force-quit completionHandler is always called after processing completes Console Logs The following logs appear when the push is sent: Submitted: com.apple.pushLaunch.jp.co.comp.MyApp.ext.mdm Application Policy response: {100, 0.00, [{[pushDisallowed]: Required:0.00, Observed:1.00},]} Decision: AMNP I also see: Insufficient history window for deviceActivityLikelihood stream deviceActivityLikelihood returned a nil timeline Questions Under what conditions are pushDisallowed and Decision: AMNP generated? What factors can cause iOS to reject a background launch triggered by a Silent Push Notification? Since Alert Push notifications are received successfully, is it reasonable to conclude that APNs configuration, topic configuration, and device token usage are correct? Are there any specific settings, entitlements, or implementation details that should be reviewed to resolve the pushDisallowed condition? The behavior differs between the Debug build launched from Xcode and the TestFlight build running on the same device. Are there any restrictions, policies, or differences applied to TestFlight builds that could explain this behavior? If the observed behavior is expected by design, what would Apple recommend as the appropriate architecture or API for server-triggered background processing in this scenario? Thank you for your time and assistance.

Hi I developed a music app that plays offline audio and displays lyrics using Live Activities. According to ActivityKit documentation, Live Activities can be updated from the background. However, in my case, updates stop after ~30 seconds when the app goes to the background or the device is locked. Important points: The app continues running in the background (audio playback works fine using AVAudioSession with .playback) Background code execution is working as expected Only the Live Activity stops updating I am not using push updates since this is an offline app. Is there any limitation or requirement for updating Live Activities continuously in the background during audio playback? Audio Session Configuration let session = AVAudioSession.sharedInstance() try session.setCategory( .playback, mode: .default, options: [.mixWithOthers] // ✅ DO NOT interrupt other audio ) try session.setActive(true) print("✅ [AudioSession] Activated with mixWithOthers") } catch { print("❌ [AudioSession] Error: \(error)") } Live Activity Update Methods guard let activity = getLiveActivity(for: recordID) else{ print("⚠️ No Live Activity found for recordID: \(recordID)") return } guard activity.activityState == .active else { print("⚠️ Activity is not active") return } Task { let content = ActivityContent( state: state, staleDate: Date().addingTimeInterval(60 * 60 * 12), relevanceScore: 1.0 ) await activity.update(content) print("✅ Live Activity updated with ActivityContent") } }

'm building a peer-to-peer mesh messaging app using MultipeerConnectivity. The app implements TTL-bounded flooding relay so messages can traverse multiple hops across devices that aren't directly connected to each other. The core limitation I'm hitting: MPC stops browsing and advertising when the app is backgrounded, which means a node can no longer relay messages for the rest of the mesh. For the mesh to be useful in practice, nodes need to stay active as relays even when users switch to other apps. I'm aware of the standard options: . Background task extension (beginBackgroundTask) — only buys ~30 seconds, not a real solution . Push notifications (APNs) — requires a server, defeats the goal of a fully offline/local mesh . CoreBluetooth with state preservation/restoration — genuine background capability, but essentially a full rewrite of the transport layer, and BLE throughput (~100–250 kbps) would hurt larger payloads Before committing to a CoreBluetooth rewrite, I want to make sure I'm not missing anything. specifically questions are: Is there any way to keep an MCNearbyServiceAdvertiser or MCNearbyServiceBrowser running in the background that I'm not aware of? Does MCSession maintain existing connections long enough in the background to be useful for relay (i.e., does it survive past the background task expiry)? Is Network.framework's local network discovery (NWBrowser with Bonjour) any more background-friendly than MPC's browser/advertiser? • Has anyone successfully implemented a hybrid approach — CoreBluetooth for background discovery/signaling + a higher-bandwidth channel (WiFi Direct or Network.framework TCP) negotiated when foregrounded? • Are there any entitlements or capabilities (e.g., AccessorySetupKit, NEAppProxyProvider, or anything in the networking extension family) that could help here that aren't commonly discussed? The relay/routing layer, E2EE, and message dedup all sit above the transport and are transport-agnostic, so the rewrite scope is limited to the discovery and session management layer — but it's still significant. Any experience with this pattern would be very helpful.

Hi everyone! I'm writing a watch app using backgroud refresh. But the backround task was not triggered either on simulator or real watch device. main code

Hello everyone, I have developed an app that is a local networking monitor app for a specific building automation protocol. I have searched the forum and I think I have found some older posts regarding this topic but I could not figure out if my issue falls under the same category. So my app allows the user to connect to local protocol devices, and start a monitor session where they can see incoming/outgoing packets. The connections are UDP or TCP and require opening a socket. Currently, backgrounding the app will make the OS terminate the socket connection, therefore ending the monitor, even if the app is backgrounded by user, to let's say, perform some other task in their phone. I have several requests from users to improve the app by allowing the monitor to continue while the app is backgrounded. However, by reading the relevant documents, I have found this to be almost impossible in iOS app. I have considered: Remote Push Notifications (APNs): The app operates on LAN so this is not an option, since I do not have an infrastructure to somehow send notifications to keep app process alive. Background Tasks (BGTaskScheduler): Not my case, since I do not want periodic execution. The app requires continuous socket listening. VoIP, VPN, or Audio Background Modes: My app does not fall under any of these categories, even though this would solve my situation. By searching around a bit more, I might be able to use either BGProcessingTask, which would allow my app at least to run for some minutes and show the user that they have to foreground it in order to not stop the monitor process, or maybe even App Intents framework. Has anyone faced similar requirement for their app? Any tip or point to a direction I should investigate more? Thanks, Nikos

I have a weird situation arising in my app where calling BGTaskScheduler.shared.submit(request) seems to fail silently, without raising any of the BGTaskScheduler.Error's. Here's what's happening. A user registers and submits 5 BGContinuedProcessingTask's, with different ID's using the wildcard. When trying to submit the 6th task like this: try bgTask.submit() //submit task isCreatingBGTask = false // toggle ProgressView off dismiss() //Dismiss the sheet The sheet will dismiss, but the device never gives the haptic feedback, and the task is not visible in the notification centre. Having a maximum number of running tasks makes sense, but why isn't it raising the error BGTaskScheduler.Error(.immediateRunIneligible). It also doesn't seem like there's a way to query the tasks that are in progress (at least I couldn't find a way). So for now I'll just track my own tasks manually, and prevent submission at 5 tasks, but I'm wondering what would happen if another app had 2 tasks going, and then my user tries to submit 3 or something like that.

I'm implementing PHBackgroundResourceUploadExtension to back up photos and videos to our cloud storage service. During testing, I observed that iCloud-optimized photos (where the full-resolution original is stored in iCloud, not on device) do not upload. The upload job appears to silently skip these assets. Questions: Is this behavior intentional/documented? I couldn't find explicit mention of this limitation. If the device only has the optimized/thumbnail version locally, does the system: - Automatically download the full-resolution asset from iCloud before uploading? - Skip the asset entirely? - Return an error via PHAssetResourceUploadJobChangeRequest? For a complete backup solution, should we: - Pre-fetch full-resolution assets using PHAssetResourceManager.requestData(for:options:) before creating upload jobs? - Use a hybrid approach (this extension for local assets + separate logic for iCloud-only assets)? Environment: iOS 26, Xcode 18

I'm implementing a PHBackgroundResourceUploadExtension to back up photos and videos from the user's library to our cloud storage service. Our existing upload infrastructure uses chunked uploads for large files (splitting videos into smaller byte ranges and uploading each chunk separately). This approach: Allows resumable uploads if interrupted Stays within server-side request size limits Provides granular progress tracking Looking at the PHAssetResourceUploadJobChangeRequest.createJob(destination:resource:) API, I don't see a way to specify byte ranges or create multiple jobs for chunks of the same resource. Questions: Does the system handle large files (1GB+) automatically under the hood, or is there a recommended maximum file size for a single upload job? Is there a supported pattern for chunked/resumable uploads, or should the destination URL endpoint handle the entire file in one request? If our server requires chunked uploads (e.g., BITS protocol with CreateSession → Fragment → CloseSession), is this extension the right mechanism, or should we use a different approach for large videos? Any guidance on best practices for large asset uploads would be greatly appreciated. Environment: iOS 26, Xcode 18

I'm developing a PHBackgroundResourceUploadExtension and finding it difficult to debug because the system controls when the extension launches. Current experience: The extension starts at unpredictable times (anywhere from 1 minute to several hours after photos are added) By the time I attach the debugger, the upload may have already completed or failed Breakpoints in init() or early lifecycle methods are often missed Questions: Is there a way to force-launch the extension during development (similar to how we can manually trigger Background App Refresh in Xcode)? Are there any launch arguments or environment variables that put the extension in a debug/eager mode? I tried taking photos/videos, but this doesn't trigged app extension in all cases. Any tips for improving the debug cycle would be greatly appreciated. Environment: iOS 26, Xcode 18

I just noticed something on macOS 27 beta 1 and I'm not sure if it's a bug or just how the new feature works. After quitting an app with Cmd+Q, the Dock keeps showing the gray dot with the "Running in Background" message. So I checked — ps aux shows nothing running for the app at all. The only trace is its auto-updater job in launchctl list (com.anthropic.claudefordesktop.ShipIt), which is registered but has no PID, so it's not actually executing anything. Out of curiosity I tried Discord and got the exact same thing (com.discord.discord.ShipIt), so this probably happens with any Electron app that uses the Squirrel updater. Is this intended behavior? Trying to understand if the indicator reflects registered background items (and not just live processes) so I know what to expect for Electron-based apps.
