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.

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.

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

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.

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

I am working with Apple HealthKit, and I need to add functionality to my app that allows a user's Apple Watch to automatically send the relevant data for their workout session (e.g. vo2 max, start timestamp, end timestamp, heartbeat, duration etc) as soon as they end their workout. This would need to work for any type of workout they do. E.g. if they are doing a running session, when they end their workout my app needs to receive the data for that running session almost instantly. I know that enableBackgroundDelivery allows my app to listen to changes in Apple Health in the background, but I'm not sure which method in HealthKit will allow me to implement the above use case. Does anyone have any pointers? I just want to know what methods in HealthKit will allow me to achieve this.

Hi there, Thanks for the great tutorial for WorkoutKit, that can be found here: https://developer.apple.com/videos/play/wwdc2023/10016/ In my view Text(scheduledWorkout.plan.workout.activity.displayName) in SamplePlannerView.swift (the main view) does not show the correct string. For example for the running workout, it should show: "New Running Workout". This string is set in WorkoutStore.swift. However, it shows "Outdoor Running", which is the type of workout but not the display name that was given to it. Best regards, Patrick

Where are Apple Watch fitness goals stored in HealthKit?

We have an app that reads data from the Apple Health Kit that is about 5 years old and we stopped receiving data from the app. While investigate why it quit working we are seeing some messages in the console log when we plug a phone into a mac that we are trying to get clarification on. We are seeing from the log: healthd 'STARTING: com.apple.healthkit.background-delivery.:<thread?>' followed by a: dasd 'COMPLETED com.apple.healthkit.background-delivery.:<thread?> at priority 30 then a dasd 'NO LONGER RUNNING com.apple.healthkit.background-delivery.:<thread?> ... Tasks running in the group [com.apple.dash.default] are 1! I was looking for some clarification on what these messages mean. Do they mean that our app was started and that the process completed successfully or, is it a warning saying that something abnormal happened. Also, I'm coming up short on documentation when I google for these messages. Is there a repository out there to help me make sense of what I'm seeing? Thanks for any insight!

Hi, I am running the "Building a multidevice workout app" sample: https://developer.apple.com/documentation/healthkit/workouts_and_activity_rings/building_a_multidevice_workout_app I do not get any values for the .cyclingSpeed Value? Is this correct or should there be any value while moving around? Also i wonder if i can get the GPS values like altimeter or location from the HKWorkoutSession? Thanks

My app's Widgets on iPhone rely on access to the Health Store to update. This makes them appearing in the new StandBy mode not a good experience as they never update. Is there a way to opt out of this mode but keep the options for my users to put Widgets on their home screen? Thanks

So almost every EPIC customer is now at a version that would allow their medical records to be imported, many of them just haven't filled out the Apple form to list their organization. EPIC does publish a list of the FHIR endpoints for all of these customers though. Functionally it should be possible to write an app that authenticates the user to their provider, and downloads the FHIR data from the API, and then pushes it into Apple Health. The two things I'm not clear on though are: Are the Medical Records available to write to from an app, or is it only available through organizations registered through Apple using their UI? Would Apple consider this a replication of their functionality as far as App Store T's & C's go?
