Reply to PushToTalk
The audio recorded by clicking the Bluetooth device button is noise. The method called by Bluetooth devices is (requestBeginTransmitting), which enables AVAudioEngine recording in the (channelManager: PTChannelManager, didActivate audioSession: AVAudioSession) method. First off, I want to clarify that possible background activation paths here: The user pushes the talk button using the systems on screen UI. The app is Bluetooth authorized and adds directly calls requestBeginTransmitting() because of a BLE event from a proprietary accessory. The app has set setAccessoryButtonEventsEnabled(...) to true and the user sends non-HFP* remote control event to the PTT system. The standard example of this is pressing the play button on an A2DP/HFP Bluetooth accessory that's currently in playback mode. *HFP events are automatically handled by the system through the standard delegate system. Expanding on #3, this is how the PTT system provides its own support for the experience many PTT apps had previously implemented tha

Reply to Attach a debugger to app launched via `devicectrl`
Since we're talking about debuggers here, I just want to say that having DWARF (1) in your user name is excellent — thanks for the chuckle! that's actually funny; i never made that connection myself 🙈. [quote='862513022, DTS Engineer, /thread/804250?answerId=862513022#862513022'] As to attaching your custom debugger to a process with devicectl, this is not possible with the currently available commands provided by that tool. Our folks who work on the tooling around that command are interested in hearing what your needs are, so please send them some information on the type of functionality you need through Feedback Assistant. Once you've done that, please post the FB number here for reference. [/quote] Thanx! i have logged a feedback as FB20753296 just now. Please don't hesitate to let me know if i can provide any more specifics or details to make this more actionable. Getting this functionality would really help us out a lot. Thanx for your attention to the matter, marc

URL filter app with multiple configurations
Hello, We've been working on an app that uses the new NEUrlFilter API and we've got a question. Currently, the system is designed with the assumption that a single app == usecase == single remote database. But what if we would like to give the user the ability to use different blocklists? For example, the user may want to: Block scam domains Block tracking domains Block adult domains Or any composition of these 3 What should we do to give the user this option? It seems that we could differentiate different databases by using different PIR service hostnames, but that would also mean that we'll have to send several requests for the same usecase but with different PIR service hostnames (and they'll all share the same app bundle ID). Will these requests be accepted then? If not, is there an alternative? PS: By sending a request I mean submitting this form

SMAppService
Hello, https://developer.apple.com/forums/thread/802443 https://developer.apple.com/documentation/servicemanagement/updating-helper-executables-from-earlier-versions-of-macos https://developer.apple.com/documentation/ServiceManagement/updating-your-app-package-installer-to-use-the-new-service-management-api#Run-the-sample-launch-agent Read these. Earlier we had a setup with SMJobBless, now we have migrated to SMAppService. Everything is working fine, the new API seems easier to manage, but we are having issues with updating the daemon. I was wondering, what is the right process for updating a daemon from app side? What we are doing so far: App asks daemon for version If version is lower than expected: daemon.unregister(), wait a second and daemon.register() again. The why? We have noticed that unregistering/registering multiple times, of same daemon, can cause the daemon to stop working as expected. The daemon toggle in Mac Settings -> Login Items & Extensions can be on or off, but the app can

macOS 15 (Sequoia): Endpoint Security client runs by hand, but LaunchDaemon fails with TCC “Full Disk Access” denial on unmanaged Macs
Platforms: macOS 15.x (Sequoia), Intel-Based App type: Endpoint Security (ES) client, notarized Developer ID app + LaunchDaemon Goal: Boot-time ES client that runs on any Mac (managed or unmanaged) Summary Our ES client launches and functions when started manually (terminal), but when loaded as a LaunchDaemon it fails to initialize the ES connection with: (libEndpointSecurity.dylib) Failed to open service: 0xe00002d8: Caller lacks TCC authorization for Full Disk Access We can’t find a supported way to grant Full Disk Access (SystemPolicyAllFiles) to a system daemon on unmanaged Macs (no MDM). Local installation of a PPPC (TCC) profile is rejected as “must originate from a user-approved MDM server.” We’re seeking confirmation: Is MDM now the only supported path for a boot-time ES daemon that requires FDA?

DriverKit DEXT Logs Only Once, Subsequent Logs Are Lost Despite Normal Functionality
Hello everyone, I've encountered a very strange and persistent logging issue with my DriverKit DEXT and would appreciate any insights from the community. [Problem Summary] My DriverKit DEXT, along with its companion Swift app, is functionally working perfectly. I can repeatedly call methods in the DEXT from the app (e.g., a Ping-Pong test and a StaticProcessInbandTask call) and receive the correct response every time. However, the os_log messages within my IOUserClient subclass are only successfully recorded for the very first set of interactions. After that, all subsequent logs are completely missing. What's even stranger is that all successfully recorded logs are attributed to the kernel: process, even for purely user-space methods like ExternalMethod. [Development Environment] macOS: 15.7.1 Xcode: 16.4 Hardware: MacBook Pro M1 DEXT Logging Macro (Log.h): #include #define Log(fmt, ...) do { os_log(OS_LOG_DEFAULT, [%{public}s] fmt, __FUNCTION__, ##__VA_ARGS__); } while (0) [Steps to Reproduce &

Reply to Notarization Incomplete for Github Workflows
I am new to the apple developer program...The software is entirely written in python and includes ffmpeg That's probably the single most difficult type of software you can try to build on a Mac. We are currently adding the signing and notarization of the app to our github workflow. Have you tried to do any of this not using a GitHub workflow? Because I hate to tell you this, but most people who experience notarization problems get stuck at a much later stage. You haven't got to the difficult part yet. I would like feedback about if there is a fundamental flaw in our approach for signing and notarizing our application, so that we can identify it. I recommend skipping all the automation stuff until you confirm that your notarized app actually runs. Notarization adds a lot of runtime checks that are particularly difficult for Python apps to pass. I would appreciate some guidelines about how long to expect this notarization step to take until we can get notarization to finish within 10s of minutes, as we have a h

Is there any way to access real-time sleep stage data from Apple Watch?
I'm trying to make a watchOS app that uses sleep data to wake users up when they enter lighter sleep stages. Apple has HealthKit, which exposes HKCategoryValueSleepAnalysis to view each stage throughout sleep, but unfortunately, this data is only written after the user wakes up. I did some research and found that the Apple Watch’s sleep classifier is part of Apple’s private system process, and apps can’t access that model directly or as it’s running. So, there’s no way to “record” my own data stream and match it with Apple’s classification during the night. Has anyone found a way to approximate or access live sleep-stage data in another way? I’m thinking of combining CoreMotion (for movement) and heart rate data from a HKWorkoutSession to infer stages myself, but I’m wondering if there’s any Apple-approved or more accurate approach for this. In other words, is there any way to use an Apple Watch to detect sleep stages accurately while the user is still asleep for the purpose of timing an optimal wake

Reply to Bluetooth work with BGTaskScheduler
You can use BGTaskScheduler, especially BGProcessingTask to perform long running actions, including CoreBluetooth data transfer, but you can't have defined schedules for background tasks. They will be run by the system whenever it is appropriate to do so, and not being run is also a possibility. You may want to read about iOS Background Execution Limits before deciding to depend on background tasks. In any case, I am not sure how this will help. With Bluetooth state restoration, and for being woken up from suspended state there is indeed a ~10 second time limit, but that is per Bluetooth event, not for the whole task you are trying to do. If you need a minute to download the whole set of data from the device, you would not be doing that all at once anyways. The device will be writing the data in pieces, and as long as the subsequent writes to a notifying characteristic happens within the ~10 second limit, your app's time will be topped up. So, as long as you take less than 10 seconds to process each

Notarization Incomplete for Github Workflows
Hello, I am new to the apple developer program. I, and my team, are working on porting some medical software that we have written from Windows to MacOS. We obviously want to notarize our app to make it easy for professionals and colleagues to use. The software is entirely written in python and includes ffmpeg for one of the features to export the medical data to video and compiled to a single file with pyinstaller, like so: pyinstaller app_name.py --noconfirm --onefile --add-data ffmpeg:ffmpeg chmod +x dist/app_name* We are currently adding the signing and notarization of the app to our github workflow. The workflow build a successful app with the correct structure and is able to be run if we allow it past the MacOS firewall. We are signing the app like so: run: | BINARY_PATH=dist/app_name IDENTITY=$(security find-identity -p codesigning -v | grep -E 'Developer ID Application|Mac Developer' | head -n1 | awk -F '{print $2}') echo Using identity: $IDENTITY security unlock-keychain -p build.keychain codesign --

Feature Request – Real-time HealthKit Streaming API for Trusted CarPlay Partners (e.g., Mercedes-Benz ENERGIZING)
Current HealthKit APIs provide access to heart-rate data through queries, but not as a true real-time stream. This limitation prevents systems such as Mercedes-Benz ENERGIZING from dynamically adapting the vehicle environment — including light, sound, seat massage and climate — to the driver’s physiological state. The ENERGIZING Coach developed by Mercedes-Benz uses continuous biometric feedback to enhance comfort, focus and safety by adjusting sensory stimuli based on live pulse data. Garmin wearables can already support this because they offer open Bluetooth Low Energy protocols. The Apple Watch, on the other hand, stores heart-rate data securely in HealthKit and makes it available through delayed write intervals. As a result, the current query mechanisms such as HKAnchoredObjectQuery or HKObserverQuery deliver updates with a latency of several seconds to minutes, which is too slow for the type of sub-second reaction required by driver-assistance or wellness systems. I would like to propose that Apple consi
