Hi everyone, I am trying to send a request to my server in my watch application when HKObserverQuery is triggered. This is working fine when my app is in foreground however the request is not sending when the app manually terminated or in background. HKObserverQuery works fine and triggered in these cases however the request is not sending. I researched about URLSessionConfiguration.background and background sessions but I could not figure it out. I don't want to download or upload a file, I just want to send a simple request when HKObserverQuery is triggered. Can you show me to a path way to make it possible? I am trying to test my watch app with my iPhone, I am assuming the behavior of these scenarios might be same in both device, am I correct? let urlsession = URLSession(configuration: URLSessionConfiguration.background(withIdentifier: "enablement"), delegate: self, delegateQueue: nil) let dataTask = urlsession.dataTask(with: urlRequest) dataTask.resume() As shown in the code snippet, I tried to set background configuration to my URLSession. I enabled background fetch in background modes. Apple documentation says, dataTask can not run in background -> https://developer.apple.com/documentation/foundation/urlsessiontask However I don't want to perform a long running task such as downloading or uploading.

I've realised with the sample code from the WWDC video below I'm getting the following error when trying to use the iPhone simulator and apple watch simulator paired. Whenever i try to test out the sample project I'm getting the following error. Failed to send data: Error Domain=com.apple.healthkit Code=300 "Remote device is unreachable" UserInfo={NSLocalizedDescription=Remote device is unreachable, NSUnderlyingError=0x600000c9c900 {Error Domain=RPErrorDomain Code=-6727 "kNotFoundErr ('rapport:rdid:PairedCompanion' not found)" UserInfo={cuErrorDesc=kNotFoundErr ('rapport:rdid:PairedCompanion' not found), cuErrorMsg='rapport:rdid:PairedCompanion' not found, NSLocalizedDescription=kNotFoundErr ('rapport:rdid:PairedCompanion' not found)}}} Is it not possible to not test out the new WorkoutKit mirroring API's using the simulator? Currently right now if you run the project you'll notice that you can start a workout session on the iPhone > Apple Watch but there is no way to control and mirror on both devices at the moment i.e You can't control the iPhone app on the Apple Watch and vice versa. Also because of this the iPhone can't send data to the Apple Watch i.e. pause, end, water etc. I'm guessing this is meant to be possible since it seems a bit strange to only be able to test this out with actual devices.

Im building a workout app to track swimming workouts for watchos 11. Triggering .prepare() on my HKWorkoutSession does not change the session state HKWorkoutSessionState. Below is my prepare function which should transition the session state to HKWorkoutSessionStatePrepared. Nothing is thrown in the delegates, the state just wont change? I have tried erasing, restarting, use another version of xcode and another simulator runtime. func prepare() { guard self.session == nil else { fatalError("Session already exist") } // Configure Workout Type let config = HKWorkoutConfiguration() config.activityType = .swimming config.swimmingLocationType = .openWater config.locationType = .outdoor self.Workoutconfig = config // Create Session do { guard store.authorizationStatus(for: .workoutType()) == .sharingAuthorized else { fatalError("Lack of permission to start workout") } let session = try HKWorkoutSession(healthStore: store, configuration: config) self.session = session self.builder = session.associatedWorkoutBuilder() Logger.diveController.info("Successfully created workout session") builder?.dataSource = HKLiveWorkoutDataSource(healthStore: store, workoutConfiguration: config) self.session?.delegate = self self.builder?.delegate = self if self.session == nil { fatalError("No workout session created") } if self.builder == nil { fatalError("No workout builder created") } self.session?.prepare() logger.debug("Session Started at: \(self.session?.startDate ?? Date())") logger.debug("Session State: \(self.session?.state.description ?? "")") if self.session?.state != .prepared { reset() fatalError("Failed To Prepare") } } catch { Logger.diveController.error("Error starting workout session: \(error.localizedDescription)") } }

Hi, I am using HealthKit for the first time. I am using HKStatisticsCollectionQuery. I am running my code iOS 17 on a physical iPhone. It takes several seconds to query data, for example 1 day worth of heart rate at 1 minute resolution. I changed the resolution to 1 hour, expecting it to be faster, but it's pretty much the same… I have been following the official documentation and sample code. I also compiled in Release, but that didn't really help for HKStatisticsCollectionQuery. I quickly looked with Instruments, the app is spending a lot of time in decoding data with NSXPCDecoder. Is there a way to speed data retrieval? Or this is "expected" latency?

I bought my phone on April 1st week, 2024. In September battery was 96% cycle count 260. Now after 1 month battery health is 90% in cycle count 300. I am using my phone everyday4-5 hours and maitaining 20-80 charging. I didn't play any kind of games in my device. My question is why apple claim 1000 cycle count and 80% will be? And how to solve this issue?

Hey I'm a college student and I'm open to apple for product testing in real time willing to test the new apple watch series line up. If anyone's willing to contact please let me know

I am having trouble finding clear information about this. I want my app to collect and aggregate user data to provide useful analytics to the user and userbase. Can data accessed from HealthKit be stored on a database outside the Apple ecosystem and used for analytics? The data will not be used for marketing and will not be shared. It will be used only for the benefit of the user's understanding of their health and for the community that uses the app. If not, what if the data is anonymized first before being exported to a 3rd party database?

Is there anywhere that describes in detail how third party workout apps can use the new effort score functionality? I can't see much in the documentation or any of the WWDC videos. In particular it would be useful to know if an effort score is automatically calculated for workouts created with third party apps? It doesn't seem to happen but some people say it takes weeks / months before watchOS starts calculating it for third party apps. If it doesn't happen automatically then how can the app set it? I tried the new relateWorkoutEffortSample API but that didn't work for me (see https://developer.apple.com/forums/thread/763539). If I could get it working then how should I determine a default effort score based on the workout metrics? Is that something that the app should do? If so then it would be good to be consistent with watchOS so some idea of how that is calculating effort scores would be useful. Sorry for all the questions, especially if there is an article in the documentation or a video that I have missed.

Can’t start fitness video with my iPhone on my tv since new update 18.1. Air play is connecting I see the countdown then the dots rolling but nothing happens and I end up receiving a « can’t read video » message. I’m using an iphone 16 pro max, an apple watch ultra (1st gen) and an apple tv HD (A1625 model). I have almost the same issue with a more recent Apple TV, but on that one it’s just painfully long before the video starts but it does start eventually (just taking much longer than it used to). That some tv is an A2843 model (apple tv 4k 3rd gen). Has anyone else had this issue?

Apple is using the RPE scale for workout effort scores. This stands for the Rate of Perceived Exertion. They're specifically using the CR-10 scale, at least from what I can tell by saving values to HealthKit. They only accept value between 0 and 10. Has anyone been able to find a scientific or academic paper on how they have chosen their different effort breakouts? Right from the Fitness app on iPhone and Activity app on Apple Watch: 1-3 Easy 4-6 Moderate 7-8 Hard 9-10 All Out There is zero documentation on these new types, which makes it difficult for workout recording apps to properly and appropriately save this new data type. Sure, we can use the Apple apps as a reference, but since there isn't a built-in Apple SwiftUI sheet to present this data, and no references to academia to point our users to, our solutions would just look the same. FB15315876 - Documentation / HealthKit: Publish documentation about .workoutEffortScore and .estimatedWorkoutEffortScore FB15316109 - Documentation / HealthKit: Add documentation to .estimatedWorkoutEffortScore and .workoutEffortScore that you can't save those samples via the save API and that they must be related and let that API save the sample FB15316251 - Documentation / HealthKit: Add documentation for acceptible values of .estimatedWorkoutEffortScore and .workoutEffortScore - don't rely on a runtime error! Apple missed making an enum for all third party developers this year.

Hello, I’m currently developing a fitness app for watchOS that lets a user to manually set a desired heart rate target zone (enter numbers representing the lower and upper boundaries) and start a workout (right now it’s only “Other” type). After that my app monitors user’s heart rate and alerts them when they’re out of zone. When user ends the workout, the info about this workout appears on “Fitness” iOS app, and user can see the workout data like Workout Time, Active and Total Calories, Avg. Heart Rate. Also user can see Heart Rate chart with info how their heart rate was changing during a workout (see the Figure 1). Now to the question. When user clicks “Show More” button above the Heart Rate chart, they can see the same Heart Rate chart and another one, with Post-Workout Heart Rate (see the Figure 2). But there is no “Estimated time in each heart rate zone” as one can see in the workout’s details that were recorded from Apple’s workout (watchOS “Workout” app, for a workout of “Other” type as well). Please see the Figure 3. The question is: is it possible to add “Estimated time in each heart rate zone” to workout recorded via my third-party app so it would look like on the Figure 3 in "Fitness" iOS app, and if it's possible, what steps should I undertake to implement this ? Thanks in advance! I posted the screenshots in the replies to the post, because otherwise I was not able to submit a post ("sensitive language" warning, I suspect it's because of the ids in the attached screenshot's urls)

Is there way to read the Apple Heart rate zones from HealthKit? I want to read the min/max bpm for each of the 1-5 zones. I went through the Apple HealthKit developer documentation but couldn't find it https://developer.apple.com/documentation/healthkit

we are seeing what appears to be an internal healthkit error appearing in our app.  not sure if it's connected, but we've mostly seen it reported on devices running ios 16.  even though our app's primary language is japanese, and in all reported occurrences the app was running in japanese, the error message itself appears in english.  searching the error string on the web yields surprisingly few results (including only two mentions on this forum that i could find, neither of which seemed relevant).  this would seem to suggest that it's coming from something deep inside healthkit, since the error message is not localized.  in all reported cases, the user had recently upgraded to a new iphone.  in most cases, the problem only occurs on the new device even though everything had been working correctly prior to the upgrade.  the error occurs when the app is unable to read step count data from healthkit. we have confirmed that the app has been granted access permissions to all health data via os settings.  we've also tried having the user toggling those settings off, then back on, rebooting the device, deleting and reinstalling the app, etc., to no avail. the error message is "Unable to invalidate interval: no data source avallable." we'd appreciate it if anyone can shed more light on this issue. thanks!

I'm trying to hook into the new workoutEffort score supported in iOS 18, I am collecting this information from users when they submit their workout and trying to add a sample to the HKWorkout in the same manner as I've been adding other samples like bodyweight, calories burned, etc. I'm receiving the error: HKWorkout: Sample of type HKQuantityTypeIdentifierWorkoutEffortScore must be related to a workout I tried adding the samples using HKWorkoutBuilder.add([samples]) as which has been working perfectly for calories burned & bodyweight, but I am receiving the above error for workoutEffortScore As a second approach, I tried adding the sample after I called finishWorkout on the HKWorkoutBuilder and received back the HKWorkout object using HKHealthStore.add([samples], to: HKWorkout) and am still receiving the same error! I don't know otherwise how to relate a sample to a workout, I thought those were the APIs to do so? I'm using Xcode 16.0 RC (16A242) and testing on an iOS 16 Pro simulator

The HealthKit permission sheet is showing up every time the app opens for a few users of my app. It doesn't matter what action they take in the sheet. I have had them try toggling the permissions from the HealthKit system settings but that did not happen to fix the problem. Has anyone experienced this problem or know a fix? Its affecting a few users of my app. I haven't been able to find what in my code could be doing this, I suspect its a bug on HealthKit's side for specific users. I can't find anyone reporting this problem elsewhere so I have to assume its my fault, but the docs clearly state that the permission sheet will only be presented once.

There's no option to help me turn it on in my iPhone 16 Pro Max MYW43LL/A (iOS 18.1 developer beta) and Apple Watch Series 10 MWX13LW/A (watchOS 11 Developer Beta).

My app is an outdoor exercise tracking app that allows you to start exercising from the Control widget。 I want to prompt the user with an AppIntentError.PermissionRequired.location error when the user doesn't authorize Core Location permissions. When I throw error in the Intent, tap the Control widget doesn't do anything and doesn't give the user any indication of what's happening

I am encountering issues on my device running iOS 18 that fetching heart rate samples associated to a given workout is very slow. Like 10+ seconds slow. This is unacceptable and unexpected. In producing a video to attach to a feedback, I also observed that Apple Health app displays incorrect information if a workout effort score is associated to a workout. In this image, you can see the Health app bug: Total Resting Energy != Estimated Workout Effort Score Here is the same workout after I delete the workout effort score using the Apple Health app: Can anyone else see if attempting to view 'heart rate' data within the workout summary in Apple Health is unbearably slow if that workout also has an effort score associated? My steps: Record workout (Apple Activity app on watchOS) Associate effort score View the workout on Apple Health (iOS) Attempt to view it's heart rate samples Observe very slow loading times Observe the incorrect cell label and value and disappearance of resting energy cell data Remove/disassociate the effort score from the workout by tapping the workout effort row, and swipe to delete the value. Navigate back, navigate back, and then go into the workout detail again At this time the UI fixes itself, but the loading of heart rate data is still super slow FB15269657 - HealthKit: Sample query to fetch heart rate samples associated to a workout is taking over 10 seconds - computing 'time in heart rate zone' FB15278790 - Health: Workout summary 'Total Resting Energy' label has value of 'Estimated Workout Effort Score' for a value, pushed view shows empty

Hello HealthKit Experts & Enthusiasts! I am building an app called one sec which forces people to take a deep breath before they can use social media apps (it’s using Shortcuts Automations for that). One important feature of one sec is the Good Morning Countdown: For a specified time after waking up (e.g. 30mins) selected apps are blocked completely. This helps to start the day screen-free. They way it works is, the user grants access to read HKCategoryTypeIdentifier.sleepAnalysis data. I have implemented a HKObserverQuery and enableBackgroundDelivery in order to be informed whenever new HKCategoryTypeIdentifier.sleepAnalysis becomes available. I noticed that when I have my device connected to Xcode, this works as expected. However, when I quit the app and launch it from my Home Screen, my observer query is not informed about new sleep data (except when my app is running in foreground). Any ideas? Furthermore, I have noticed that sometimes sleep data is provided delayed to HealthKit, many minutes (sometimes even longer) after waking up, no sleep samples are to be found in the Health app. Of course, for my app it is crucial to get accurate + timely so apps can be blocked accordingly. Is this an issue that the Apple Watch first needs to send the samples to the phone? Thanks a lot for your help!

HealthKit tracker Id is the same with another Device, We are using an application to track our health progress and we are trying to connect our HealthKit to monitor our health data (steps and calories) but unfortunately we can't connect to the app (another application) at the same time because two devices is sharing just one health kit tracker ID. Can anyone help me to resolve this issue? Old phone was used by the other person before changing to new phone
