When I use BGContinuedProcessingTask to submit a task, my iPhone 12 immediately shows a notification banner displaying the task’s progress.
However, on my iPhone 15 Pro Max, there’s no response — the progress UI only appears in the Dynamic Island after I background the app.
Why is there a difference in behavior between these two devices?
Is it possible to control the UI so that the progress indicator only appears when the app moves to the background?

I am building a Mac app that launch a GUI helper app and use XPC to communicate between them.
Main app start a XPC Listener using NSXPCListener(machServiceName: "group.com.mycompany.myapp.xpc")
Launch the helper app
Helper app connect to the XPC service and listen command from main app.
What I observe is the app seems can start XPC listener while I run it via Xcode. If I run the app using TestFlight build, or via the compiled debug binary (same one that I use on Xcode), it cannot start the XPC service. Here is what I see in the Console:
[0x600000ef7570] activating connection: mach=true listener=true peer=false name=group.com.mycompany.myapp.xpc
[0x600000ef7570] listener failed to activate: xpc_error=[1: Operation not permitted]
Both main app and helper app are sandboxed and in the same App Group - if they were not, I cannot connect the helper app to main app. I can confirm the entitlement profiles did contain the app group.
If I start the main app via xcode, and then launch the helper app manually via Finder, the helper app can connect to the XPC and everything work.
It is not related to Release configuration, as the same binary work while I am debugging, but not when I open the binary manually.
For context, the main app is a Catalyst app, and helper app is an AppKit app. To start a XPC listener on Catalyst, I had do it in a AppKit bridge via bundle.
Given the app worked on Xcode, I believe this approach can work. I just cannot figure out why it only work while I am debugging.
Any pointer to debug this issue is greatly appreciated. Thanks!

Every time macOS goes to sleep the processes get suspended which is expected. But during the sleep period, all processes keep coming back and they all get a small execution window where they make some n/w requests. Regardless of what power settings i have. It also does not matter whether my app is a daemon or not
Is there any way that i can disable this so that when system is in sleep, it stays in suspended, no intermittent execution window? I have tried disabling Wake for network access setting but processes still keep getting intermittent execution window.
Is there any way that i can prevent my app from coming back while in sleep. I don't want my app to get execution window, perform some executions and then get suspended not knowing when it will get execution window again?
Hello, aspiring programmer here.
I am developing a StepCounter APP, which keeps track of how many steps I have taken and sends to an MQTT server. I am trying to make this happen even while the app is not in focus, but so far I have not been able to get this working.
First tried with silent background music, which seemed pretty inconsistent and inpractical, since I usually play youtube videoes while walking, making the app stop with its silent audio. Then tried GPS, which didnt really do anything (could be implementation problem).
Has anyone made background processing work for their apps?
The application is placed into the idle state. Subsequently, the device enters a sleep state.
While the device is in sleep, App start background task within the application successfully receives its expirationHandler callback.
App received the expiration callback and App called the end BGtask
OS did not released the Assertion.
Resulting in App getting terminated by the OS for exceeding the BG task

Hello,
I'm trying to adopt the new BGContinuedProcessingTask API, but I'm having a little trouble imagining how the API authors intended it be used. I saw the WWDC talk, but it lacked higher-level details about how to integrate this API, and I can't find a sample project.
I notice that we can list wildcard background task identifiers in our Info.plist files now, and it appears this is to be used with continued tasks - a user might start one video encoding, then while it is ongoing, enqueue another one from the same app, and these tasks would have identifiers such as "MyApp.VideoEncoding.ABCD" and "MyApp.VideoEncoding.EFGH" to distinguish them.
When it comes to implementing this, is the expectation that we:
a) Register a single handler for the wildcard pattern, which then figures out how to fulfil each request from the identifier of the passed-in task instance?
Or
b) Register a unique handler for each instance of the wildcard pattern? Since you can't unregister handlers, any resources captured by the handler would be leaked, so you'd need to make sure you only register immediately before submission - in other words register + submit should always be called as a pair.
Of course, I'd like to design my application to use this API as the authors intended it be used, but I'm just not entirely sure what that is. When I try to register a single handler for a wildcard pattern, the system rejects it at runtime (while allowing registrations for each instance of the pattern, indicating that at least my Info.plist is configured correctly). That points towards option B.
If it is option B, it's potentially worth calling that out in documentation - or even better, perhaps introduce a new call just for BGContinuedProcessingTask instead of the separate register + submit calls?
Thanks for your insight.
K
Aside: Also, it would be really nice if the handler closure would be async. Currently if you need to await on something, you need to launch an unstructured Task, but that causes issues since BGContinuedProcessingTask is not Sendable, so you can't pass it in to that Task to do things like update the title or mark the BGTask as complete.
Hi,
I have received the following report after app termination. I have researched online but cannot determine the root cause. Any tips or ideas would help please.
Could it be Location Services, UserNotification Services, or Network Requests?
Thank you,
Brendan

Hi,
I have a hard time getting my head wrapped around the possibilities of running a app or a task in a app in the background.
I have a app where I utilize MusicKit to create a playlist in Apple Music, and add songs to the playlist. Now the songs added are picked from choices made by the user, and the total number of songs to add is 75, and that takes some time. And if the user switches to a different app or the phone is locked, the add songs logic stops, and then starts again as soon as the app is active again.
What I am trying to achieve is of course for this to keep processing also when the app is not active, so basically to keep it running in the background.
But this is where I struggle to understand how I can do that - The available choice seems to be BGTaskScheduler, but that just does not seem correct. From what I understand it just schedules a task, and it will be processed whenever the app or phone "feels like it" (again, my understanding, might be wrong), and that won't work in my scenario. I want the task to start when the user taps a button, and just keep running until it is finished, regardless of if the app is active or not.
Any pointers, tips, advices out there on how I can achieve this?

Hello,
I have a question about a edge case scenario.
Before that some info on my project-
I have a launchdaemon that carries out some business logic, it also has XPC listener (built using C APIs).
Question-
Can there be a situation when the daemon is up and running but the XPC listener is down(due to some error or crash)? If yes then do I need to handle it in my code or launchd will handle it?
when the daemon is stopped or shut down, how do I stop the XPC listener? After getting listener object from xpc_connection_create_mach_service should I just call xpc_connection_cancel followed by a call to xpc_release?
Thanks!

Testing Environment:
iOS Version: 26.0 Beta 7
Xcode Version: 17.0 Beta 6
Device: iPhone 16 Pro
Description:
We are implementing the new BGContinuedProcessingTask API and are using the wildcard identifier notation as described in the official documentation. Our Info.plist is correctly configured with a permitted identifier pattern, such as com.our-bundle.export.*.
We then register a single launch handler for this exact wildcard pattern. We are performing this registration within a UIViewController, which is a supported pattern as BGContinuedProcessingTask is explicitly exempt from the "register before applicationDidFinishLaunching" requirement, according to the BGTaskScheduler.h header file. The register method correctly returns true, indicating the registration was successful.
However, when we then try to submit a task with a unique identifier that matches this pattern (e.g., com.our-bundle.export.UUID), the BGTaskScheduler.shared.submit() call throws an NSInternalInconsistencyException and terminates the app. The error reason is: 'No launch handler registered for task with identifier com.our-bundle.export.UUID'.
This indicates that the system is not correctly matching the specific, unique identifier from the submit call to the registered wildcard pattern handler. This behavior contradicts the official documentation.
Steps to Reproduce:
Create a new Xcode project.
In Signing & Capabilities, add "Background Modes" (with "Background processing" checked) and "Background GPU Access".
Add a permitted identifier (e.g., "com.company.test.*") to BGTaskSchedulerPermittedIdentifiers in Info.plist.
In a UIViewController's viewDidLoad, register a handler for the wildcard pattern. Check that the register method returns true.
Immediately after, try to submit a BGContinuedProcessingTaskRequest with a unique identifier that matches the pattern.
Expected Results:
The submit call should succeed without crashing, and the task should be scheduled.
Actual Results:
The app crashes immediately upon calling submit(). The console shows an uncaught NSInternalInconsistencyException with the reason: 'No launch handler registered for task with identifier com.company.test.UUID'.
Workaround:
The issue can be bypassed if we register a new handler for each unique identifier immediately before submitting a request with that same unique identifier. This strongly suggests the bug is in the system's wildcard pattern-matching logic.
I'm working on an enterprise product that's mainly a daemon (with Endpoint Security) without any GUI component. I'm looking into the update process for daemons/agents that was introduced with Ventura (Link), but I have to say that the entire process is just deeply unfun. Really can't stress this enough how unfun.
Anyway...
The product bundle now contains a dedicated Swift executable that calls SMAppService.register for both the daemon and agent.
It registers the app in the system preferences login items menu, but I also get an error.
Error registering daemon: Error Domain=SMAppServiceErrorDomain Code=1 "Operation not permitted" UserInfo={NSLocalizedFailureReason=Operation not permitted}
What could be the reason?
I wouldn't need to activate the items, I just need them to be added to the list, so that I can control them via launchctl.
Which leads me to my next question, how can I control bundled daemons/agents via launchctl? I tried to use launchctl enable and bootstrap, just like I do with daemons under /Library/LaunchDaemons, but all I get is
sudo launchctl enable system/com.identifier.daemon
sudo launchctl bootstrap /Path/to/daemon/launchdplist/inside/bundle/Library/LaunchDaemons/com.blub.plist
Bootstrap failed: 5: Input/output error (not super helpful error message)
I'm really frustrated by the complexity of this process and all of its pitfalls.
I'm trying to schedule a background task that will run on an iPhone and I'm looking into creating a task request using BGProcessingTaskRequest and scheduled it using BGTaskScheduler.shared.submit().
Per earliestBeginDate documentation, this property can be used to specify the earliest time a background task will be launched by OS. All clear here.
However, the question is: how is the value interpreted with respect to timezone ? Is the specified date in device timezone ? Is GMT ? Is something else ?

I abandoned Mac development back around 10.4 when I departed Apple and am playing catch-up, trying to figure out how to register a privileged helper tool that can execute commands as root in the new world order. I am developing on 13.1 and since some of these APIs debuted in 13, I'm wondering if that's ultimately the root of my problem.
Starting off with the example code provided here:
https://developer.apple.com/documentation/servicemanagement/updating-your-app-package-installer-to-use-the-new-service-management-api
Following all build/run instructions in the README to the letter, I've not been successful in getting any part of it to work as documented. When I invoke the register command the test app briefly appears in System Settings for me to enable, but once I slide the switch over, it disappears. Subsequent attempts to invoke the register command are met only with the error message:
`Unable to register Error Domain=SMAppServiceErrorDomain Code=1 "Operation not permitted" UserInfo={NSLocalizedFailureReason=Operation not permitted}
The app does not re-appear in System Settings on these subsequent invocations. When I invoke the status command the result mysteriously equates to SMAppService.Status.notFound.
The plist is in the right place with the right name and it is using the BundleProgram key exactly as supplied in the sample code project. The executable is also in the right place at Contents/Resources/SampleLaunchAgent relative to the app root.
The error messaging here is extremely disappointing and I'm not seeing any way for me to dig any further without access to the underlying Objective-C (which the Swift header docs reference almost exclusively, making it fairly clear that this was a... Swift... Port... [Pun intended]).
I'm developing a macOS console application that uses ODBC to connect to PostgreSQL. The application works fine when run normally, but fails to load the ODBC driver when debugging with LLDB(under root works fine as well).
Error Details
When running the application through LLDB, I get this sandbox denial in the system log (via log stream):
Error 0x0 0 0 kernel: (Sandbox) Sandbox: logd_helper(587) deny(1) file-read-data /opt/homebrew/lib/psqlodbcw.so
The application cannot access the PostgreSQL ODBC driver located at /opt/homebrew/lib/psqlodbcw.so(also tried copy to /usr/local/lib/...).
Environment
macOS Version: Latest Sequoia
LLDB: Using LLDB from Xcode 16.3 (/Applications/Xcode16.3.app/Contents/Developer/usr/bin/lldb)
ODBC Driver: PostgreSQL ODBC driver installed via Homebrew
Code Signing: Application is signed with Apple Development certificate
What is the recommended approach for debugging applications that need to load dynamic libraries?
Are there specific entitlements or configurations that would allow LLDB to access ODBC drivers during debugging sessions?
Any guidance would be greatly appreciated.
Thank you for any assistance!

When using the continuation API, we're required to call resume exactly once. While withCheckedContinuation helps catch runtime issues during debugging, I'm looking for ways to catch such errors at compile time or through tools like Instruments.
Is there any tool or technique that can help enforce or detect this requirement more strictly than runtime checks? Or would creating custom abstractions around Continuation be the only option to ensure safety? Any suggestions or best practices are appreciated.
Hello,
I am developing an application which is communicating with external device using BLE and L2CAP. I wonder what are the best practices of using Input & Output streams that are established with L2CAP connection when working with Swift 6 concurrency model.
I've been trying to find some examples and hints for some time now but unfortunately there isn't much available. One useful thread I've found is: https://developer.apple.com/forums/thread/756281
but it does not offer much insight into using eg. actor model with streams. I wonder if something has changed in this regards?
Also, are there any plans to migrate eg. CoreBluetooth stack to new swift 6 concurrency ?

In macOS 26 I noticed there is a section Menu Bar in System Settings which allows to toggle visibility of status items created with NSStatusItem. I'm assuming this is new, since I never noticed it before.
Currently my app has a menu item that allows toggling its status item, but now I wonder whether it should always create the status item and let the user control its visibility from System Settings. Theoretically, keeping this option inside the app could lead to confusion if the user has previously disabled the status item in System Settings, then perhaps forgot about it, and then tries to enable it inside the app, but apparently nothing happens because System Settings overrides the app setting. Should I remove the option inside the app?
This also makes me think of login items, which can be managed both in System Settings and inside the app via SMAppService. Some users ask why my app doesn't have a launch at login option, and I tell them that System Settings already offers that functionality. Since there is SMAppService I could offer an option inside the app that is kept in sync with System Settings, but I prefer to avoid duplicating functionality, particularly if it's something that is changed once by the user and then rarely (if ever) changed afterwards. But I wonder: why can login items be controlled by an app, and the status item cannot (at least I'm not aware of an API that allows to change the option in System Settings)? If the status item can be overridden in System Settings, why do login items behave differently?
