Hi, Our app has an HKObserverQuery and calls enableBackgroundDelivery(...) While running on an iPhone the background wakeup happens. While running on an iPad, it doesn't. The app can successfully query for data while in the foreground on an iPad. Is background delivery expected to work on iPad?

I have created a new project and I have added HomeKit capability but the two control box for Clinical Health Records and Background Delivery can not be switched on. are there any suggestion? thanks a lot valerio

After some years our app has been writing some data to HealthKit we decided to remove this functionality from the app. Permissions were removed from requestAuthorization(toShare:read:completion:) method. For new users everything works fine, but for users who were already asked for writing permission in Settings toggles for permissions are still on. Is it any way to update toggles list in Settings for actual state of permissions? Thanks in advance.

Even if you have granted read permission for specific health data items (such as walking, weight, etc.), calling the function below will return the permission as 'sharingDenied'. How can I obtain 'sharingAuthorized'? let stepType = HKObjectType.quantityType(forIdentifier: .stepCount)! let authorizationStatus = HKHealthStore().authorizationStatus(for: stepType) //authorizationStatus => sharingDenied

Hi, Is there anyway to share a WorkoutScheduler across an iPhone and watch app? If I create a scheduler on the phone app the watch app can't see it and creates its own. I'm using WorkoutScheduler.shared.scheduledWorkouts but end up with two identical sections at the top of the workout app Thanks

With iOS 17 creation of HKWorkout is deprecated via its init functions and the recommendation is to use HKWorkoutBuilder. If you try to init HKWorkout like you would pre iOS 17 you get this warning of deprecation: The problem is that I am creating this HKWorkout object inside unit tests in order to test a service that works with such objects. And HKWorkoutBuilder requires a HKHealthStore which itself requires to be authenticated to be able to create HKWorkoutActivity instances, like it would be when an app is running. But since the unit tests cannot accept the request on the HKHealthStore I am not sure if using HKWorkoutBuilder inside unit tests is possible. I've also tried to inherit HKHealthStore and override all of its methods, but still, store requires authorization. Any ideas on how to proceed with creating HKWorkout for unit test purposes?

Hello developers, I hope you're all doing well. I've encountered an issue that I'm struggling to resolve, and I'd greatly appreciate any insights or assistance you can offer. Issue Summary: In my watchOS app, I'm utilizing the HKWorkoutSessionDelegate protocol and the workoutSession(_:didFailWithError:) method. While everything works smoothly on watchOS 9.*, I'm facing a problematic inconsistency on watchOS 10.0 and higher. Steps to Reproduce: Create a new watchOS project with a deployment target of watchOS 10.0 or higher. Implement the HKWorkoutSessionDelegate protocol and the workoutSession(_:didFailWithError:) method. Attempt to start a workout session. Expected Behavior: I expect the workout session to commence without any issues, and the delegate method to gracefully handle any errors, without displaying an error message. Actual Behavior: Unfortunately, on watchOS 10.0 and higher, my attempts to initiate a workout session result in an error message: "Cannot start workout session while process is in the background." Version/Build: Affected watchOS versions: 10.0 and higher Non-affected watchOS versions: 9.* Reproducibility: I've confirmed that this issue is reproducible across different projects and on different simulators running watchOS 10.0 and higher. Additional Information: This inconsistency seems to be specific to watchOS versions 10.0 and higher and doesn't occur on watchOS 9.*. It's causing confusion and hampering my development process, and the error message isn't as informative as I'd like. Workaround: I've been unable to identify a workaround for this issue so far. If any of you have insights, solutions, or suggestions, I'd be grateful for your input. Please feel free to share your experiences and thoughts on this matter. Your help is greatly appreciated! Thank you for your time and assistance. Best regards, Leonid

In the wwdc2023-10023 session, we go over how the Apple Watch can be used as a primary workout session manager and the iPhone as the mirrored one. How is it possible to create a workout session on the iPhone and optionally mirror it to the Apple Watch to collect heart rate data? In iOS 17, I still cannot instantiate a HKWorkoutSession, I'm assuming it says it's available because we can have an instance of it as a mirrored copy from the Apple Watch. I find it odd that the iPhone cannot manage the primary session. I hope I'm missing something.

Will Apple Vision Pro support medical imaging diagnostic software such as Horos or Osirix. I am really curious if radiologist will be able to view and manipulate. interpret exams with this headset with ease and use built in microphone for voice recognition/dictation while using hands to manipulate the imaging and also simultaneously being able to view report in field of view. This could really unlock some major potential for interpreting at least CT, Ultrasound and MRI exams. I don't think the resolution will be high enough to interpret diagnostic x-rays and definitely not mammograms due to MQSA regulations and physicist inspections requiring more detail and information. However, I want to be at the forefront of bringing in Vision Pro headsets in the medical imaging space with rel utilization in clinical practices. It may also be beneficial for patients who are curious to see their medical imaging or even as headsets to use while undergoing medical imaging outpatient biopsy procedures for ******/etc to help put them at ease during the procedures. This could really provide patient satisfaction and I think we are scratching the surface on a world of possibilities in healthcare with devices like this. Upon utilixation, I would like to creat presentation series and share information with my Radiology colleagues at national/international meetings.

Hi Is there a way to read the sleep schedule i have set in either the health or clock apps? I found a few posts on here asking the same thing and the responce was always either no or just no responce but they are all from over 2 years ago so im not sure if something has changed since then. Up untill recently i was using a shortcuts automation to get the data but a recent update started excluding the sleep schedule alarm from the list that the shortcuts app can pull from the clock app. I dont want historical data, just when the alarm is set to go off next. I was using it to turn my lights on dim half an hour before the alarm goes off without having to set the schedule in 2 places. I have an annoyingly inconsistent morning schedule. Thanks

The app I distribute has a function that retrieves step count information from the "Healthcare" app and displays it on the app, but depending on the device, the step count may not be retrieved. When I checked the settings of the "Healthcare" app, I found that it was properly linked to the app, but for some reason I was unable to retrieve it. Is there any countermeasure in such a case? Is there anyone who has experienced a similar incident?*The same issue occurs even if the device is changed and the same Apple ID is used, so I think it is caused by the Apple ID.

Hi, I am having some trouble with uploading HealthKit data to AWS S3 in the background. As of now, when I click on the button to beginBackgroundUpdates the data is uploaded as expected. When I go off the app and add data to HealthKit nothing happens. When I go back to the app, the new data is uploaded. I am not sure why this is not happening in the background. More specifically, I am not sure if this is allowed, and if so what I am doing wrong.

Im able to reconnect to BLE device in the back ground app refresh, but Im not receiving next back ground app refresh continuation. Can someone help me with this

When the build a multi-device workout app sample project is ran, there is a problem that stops workouts from being logged with only the watch. When the workout is started from the Apple Watch with the iPhone app closed, you can usually end the workout from the watch in the first few seconds. However, if the workout lasts more than 30 seconds, when the workout is ended via the watch, everything will stall for multiple minutes or indefinitely until the iPhone app is opened. How is it reccommended to fix this issue? It makes the sample project unusable for production as is because many users may want to sometimes log a workout with their watch without the iPhone present. I haven't been able to figure out a good solution, can someone please help with this.

At the moment I am working on a small app that retrieves Activities via HealthKit and allows user to trim activities. A typical use case would be when an user forgets to finish / stop an activity recording on his watch. Has anyone experience with submit such kind of apps to the app store. Does apple even allow this kind of feature? It could harm the integrity of health data if not done correctly.

Hello, I'm trying to understand what's the difference between: HeartRateZoneAlert: static func heartRate(zone: Int) -> Self PowerZoneAlert : static func power(zone: Int) -> Self And also, why HeartRate alerts support range, but Power doesn't support Range?

I am unable to see the workout composition from preview in the new WorkoutKit framework. This is reproducible on an iPhone running iOS 17.0 running xcode 15.0 beta 2. I downloaded the Sample Planner app that showcases the new WorkoutKit framework capabilities , introduced in the session 10016 of wwdc 23. I can create workout compositions but the preview presentation doesn’t work as expected. It shows a black screen without any info. I attached a screenshot. You can reproduce it on the sample app when showing the PresentPreviewDemo view.

Dear All, Is there a way to remove a workout? In the tutorial app, it is shown how to schedule workouts. But so far, I haven't seen a way to remove them again, neither from the tutorial app nor from the workouts app on the watch. Many thanks and best regards, Patrick
