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

Auto-renewable subscriptions not loading in React Native app after App Store approval when testing via Xcode
Hello, I’m facing an issue with auto-renewable subscriptions in my React Native iOS app using react-native-iap. Before App Store approval, everything worked perfectly — I could test in-app purchases and subscriptions locally on my iPhone through Xcode using a development build and sandbox tester. After the app was approved and released on the App Store, I needed to make some updates. Now, when I build and run the same project again through Xcode (Debug, development-signed) on my iPhone, the subscriptions no longer load. The same product IDs are approved and live in App Store Connect. The live version on the App Store works fine (subscriptions load and process successfully). But on the local Xcode build, getSubscriptions() returns invalid product identifiers or an empty list. No changes were made to the bundle ID or product IDs The build is signed with an Apple Development certificate and uses the same team and bundle identifier as the published app. “In-App Purchase” capability is enabled. I’ve also

Reply to UISlider valueChanged has uninitialized UIEvent
Same issue in my app. My app had been working for 9 years but started showing this UISlider bug in iOS 26. Below used to work previously: slider.addTarget(self, action: #selector(sliderValueChanged(sender:event:)), for: .valueChanged) @objc func sliderValueChanged(sender: UISlider, event: UIEvent) { print(Slider: (slider.value), (event)) label.text = Value: (sender.value) switch event.allTouches?.first?.phase { case .began: print(began) case .moved: print(moved) case .ended: print(ended) case .cancelled: print(cancelled) default: break } } But, in iOS 26, the event being passed is uninitialized and so, event.allTouches is always nil. So, I am unable to detect what phase of the event it's in. Note that changing from UIEvent to UIControl.Event is not a solution as it's also just UIControlEvents(rawValue: 0), so unable to find what phase it's in. I have reported this as a bug: https://feedbackassistant.apple.com/feedback/20727378 EDIT: For now, the below workaround works: slider.addTarget(self,

Reply to Unable to upload an app with ExtensionFoundation
Thanks for the recommendation; I've added extra information. Basically my main concern is to isolate unstable code to make the app more stable, but also extensions are running as separate process, which would allow me to add a lot more commands to the terminal app. I also have potential uses in mind if there is no memory limit, and if we can share extensions between apps, but I think these are hills too large to climb at the moment.

File Provider Extension Memory Limit of 20MB is really limiting
I have an iOS and macOS app that includes a file provider extension. on macOS is is perfect no issues anywhere. on iOS it works for small datasets or if I do read only operations. as soon as I try to do anything with larger files I quickly hit the 20MB limit. I have solved file transfers by using chunking but when it comes to listing a folder with a couple thousand files it instantly crashes the FPE with an OOM error. works ok up to 100 files but anything beyond that crashes. I know enumerate items supports batches however the initial load form say a webdav server that has no concept of pagination will always fail to load in pieces no matter what I do. This likely explains why WebDAV was never implemented on iOS. in any case can you possibly consider upgrading the memory limit for FPE's or provide some mechanism to call our full iOS app for more processing power in the background to handle requests on demand? I do not understand where 20MB is a reasonable number. even 100MB seems more reason

Update ASCredentialIdentityStore for new Autofill PassKey registration
I have an Autofill Passkey Provider working for Safari and Chrome via WebAuthn protocol. Unfortunately, Chrome will not offer my extension as a logon credential provider unless I add the credential to the ASCredentialIdentityStore. I wonder what is the best way to access the ASCredentialIdentityStore from an AutoFill extension? I understand I cannot access it directly from the extension context, so what is the best way to trigger my container app to run, based on a new WebAuthn registration? The best I can think of so far is for the www site to provide an App Link to launch my container app as part of the registration ceremony. Safari will offer my extension even without adding it to the ASCredentialIdentityStore, so I guess I should file a request with Chrome to work this way too, given difficulty of syncing ASCredentialIdentityStore with WebAuthn registration.

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! 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. — Ed Ford,  DTS Engineer (1): https://dwarfstd.org
