Hello everyone, I'm developing an app for visionOS that utilizes HealthKit to query heart rate data. However, I'm encountering an issue where the app doesn't retrieve the latest heart rate values. Specifically, it fails to get live heart rate data even after the data has been saved to the Health app. The readings my app displays are outdated and do not match the current values shown in the Health app. Here's what I've tried so far: Fetching Heart Rate Samples: Used HKSampleQuery and HKAnchoredObjectQuery to fetch the most recent heart rate samples. Despite this, the data retrieved is still not up-to-date. Checking Permissions: Ensured that all necessary HealthKit permissions are granted. The app has authorization to read heart rate data and write workout data. My questions are: Is there a known issue or limitation with HealthKit on visionOS that prevents apps from accessing the latest heart rate data? Are there additional steps or configurations required to access live heart rate data in visionOS apps? Has anyone successfully implemented live heart rate monitoring on visionOS, and if so, could you share how you achieved it?

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.

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

When a workout session is being recovered, if it is paused, the elapsed time will be incorrect. It will seem like that workout never was paused. The recovery works fine if the workout was never paused. Steps to reproduce: Implement recoverActiveWorkoutSession Start workout Pause session and print the elapsed time Stop simulator / cause crash When recoverActiveWorkoutSession is called the elapsed time will not equal the elapsed time when the session was paused. Here is my implementation. I haven't seen any examples online. guard let recovered = try? await healthStore.recoverActiveWorkoutSession() else {return} self.session = recovered self.builder = recovered.associatedWorkoutBuilder() self.session?.delegate = self self.builder?.delegate = self self.builder?.dataSource = HKLiveWorkoutDataSource(healthStore: healthStore, workoutConfiguration: recovered.workoutConfiguration) self.sessionState = recovered.state

I ran into a problem recently with my production app and an update for iOS 18. In this example I was using a new API added to the RC candidate of iOS 18.0, using this API as an example, I couldn't find a satisfactory way to avoid crashing on iOS 18.1 where the API was not available. I had plenty of users running the iOS 18.1 Beta and ultimately it's my fault if a version of my app did work, and then didn't after an update.... This code causes a crash on iOS 18.1 beta as the .appleSleepingBreathingDisturbances API doesn't seem to have made it's way into the beta: if #available(iOS 18.0, *), #available(watchOS 11, *) { healthKitTypesToRead.insert(HKQuantityType.quantityType(forIdentifier: .appleSleepingBreathingDisturbances)!) } I tried this but it still crashed on 18.1: if #available(iOS 18.0, *), #available(watchOS 11, *) { if let newQuantity = HKQuantityType.quantityType(forIdentifier: .appleSleepingBreathingDisturbances) { healthKitTypesToRead.insert(newQuantity) } } In the end the only way I could resolve this was the following: if #available(iOS 18.1, *){ // Do nothing } else if #available(iOS 18.0, *), #available(watchOS 11, *) { if let newQuantity = HKQuantityType.quantityType(forIdentifier: .appleSleepingBreathingDisturbances) { healthKitTypesToRead.insert(newQuantity) } } This seems like a poor solution and I'll have to ensure I release a new version of the app once iOS 18.1 has the available API added to enable support for the feature. How could I have checked availability for this API correctly without causing the app to crash? I'm asking this question more as a Swift language feature rather than issue with the specific API as I'm sure that will get resolved soon anyway. Thanks

I'm using Healthkit with the following H/W specs: Apple Watch, series 8, OS: 10.6.1 (21U580) iPhone 11 Pro, OS: 17.6.1 Mac Studio M1 Xcode ver: 16.0 (16A242d) I am trying to get Apple Watch to report heart rate, HRV, respiratory rate, and body temperature using Healthkit's HKLiveWorkoutBuilder implementing HKLiveWorkoutBuilderDelegate's workoutBuilder method. However, the only reported value that is found from the workoutBuilder method's collectedTypes (a Set of HKSampleType objects) is HKQuantityTypeIdentifierHeartRate. Nothing for HRV, respiratory rate, or body temperature. All entitlements are set up, the plist filled in, and capabilities in place. Not sure why only the heart rate is reported from the watch but nothing else. I've scoured StackOverflow, Apple developer forums, even ChatGPT but none of the solutions work. Any help most appreciate! The model code is: import Foundation import HealthKit class WatchModel: NSObject, HKLiveWorkoutBuilderDelegate, HKWorkoutSessionDelegate { private let healthStore = HKHealthStore() private var workoutSession: HKWorkoutSession! private var workoutBuilder: HKLiveWorkoutBuilder! override init() { super.init() requestAuthorization() startWorkoutSession() } private func requestAuthorization() { let heartRateType = HKQuantityType.quantityType(forIdentifier: .heartRate)! let respiratoryRateType = HKQuantityType.quantityType(forIdentifier: .respiratoryRate)! let HRVRateType = HKQuantityType.quantityType(forIdentifier: .heartRateVariabilitySDNN)! let temperatureRateType = HKQuantityType.quantityType(forIdentifier: .bodyTemperature)! let healthDataTypes: Set = [heartRateType, respiratoryRateType, HRVRateType, temperatureRateType] healthStore.requestAuthorization(toShare: healthDataTypes, read: healthDataTypes) { (success, error) in if !success { print("Authorization failed") } } } func workoutSession(_ workoutSession: HKWorkoutSession, didChangeTo toState: HKWorkoutSessionState, from fromState: HKWorkoutSessionState, date: Date) { } func workoutSession(_ workoutSession: HKWorkoutSession, didFailWithError error: any Error) { } func workoutBuilderDidCollectEvent(_ workoutBuilder: HKLiveWorkoutBuilder) { } func startWorkoutSession() { let configuration = HKWorkoutConfiguration() configuration.activityType = .other configuration.locationType = .indoor do { workoutSession = try HKWorkoutSession(healthStore: healthStore, configuration: configuration) workoutBuilder = workoutSession.associatedWorkoutBuilder() workoutBuilder.delegate = self workoutBuilder.dataSource = HKLiveWorkoutDataSource(healthStore: healthStore, workoutConfiguration: configuration) let dataSource = HKLiveWorkoutDataSource(healthStore: healthStore, workoutConfiguration: configuration) let respiratoryRate = HKQuantityType(.respiratoryRate) dataSource.enableCollection(for: respiratoryRate, predicate: nil) let bodyTemp = HKQuantityType(.bodyTemperature) dataSource.enableCollection(for: bodyTemp, predicate: nil) let hrv = HKQuantityType(.heartRateVariabilitySDNN) dataSource.enableCollection(for: hrv, predicate: nil) workoutSession.delegate = self workoutSession.startActivity(with: Date()) workoutBuilder.beginCollection(withStart: Date(), completion: { (success, error) in if let error = error { print("Error starting collection: \(error.localizedDescription)") } }) } catch { print("Failed to start workout session: \(error.localizedDescription)") } } func workoutBuilder(_ workoutBuilder: HKLiveWorkoutBuilder, didCollectDataOf collectedTypes: Set<HKSampleType>) { print("collected types: \(collectedTypes)") for type in collectedTypes { if let quantityType = type as?

Hello all, I am quite new to iOS and Swift, and before venturing further, I feel it's better to ask for advice. I have build a Type I diabetes simulator running as a NodeJS application on a server. The clients authenticate via a browser using Fitbit/Google oauth2, set up a virtual patient, then take care of the patient 24/7. The app imports the users steps and heartrate, as these influence the blood sugar variations. (https://cgmsim.com) I designed a companion app with Expo, adding high/log blood glucose alerts with push notifications. If the user doesn't have a Fitbit tracker or doesn't use Google Fit, I'd like to send their HealthKit step counts to the backend. (Using sensor data directly in Android). It works using Expo's Background Fetch and TaskManager, but the uploads from the iOS device are very irregular. I set up silent push notifications from the backend to wake up the app in the background and trigger the step count upload. It works, but it is not reliable enough. I now wrote my first local native module for iOS, where a HKObserverQuery listening for new step events, making the upload and sending the count to the JS for rendering. I used enableBackgroundDelivery and BackgroundTask for uploading the results. All the entitlements and Info.plist entries should be ok. Still my app works well only in the foreground, and not upload at all happens when in the background. As we all do, I asked Claude, and it assured me th app should work. I have doubts though, as I noticed how strict iOS is about executing background tasks. So... should I even expect this to work ?

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

Hello, We're encountering overlapping segments and discrepancies when analyzing running/workout data for a 5-mile run. The expected splits for the run are: 8:39 9:06 8:30 8:39 8:43 0:08 However, the raw data includes segments where start times begin before the previous segment ends, and there are duplicate start times. Below is a sample of the raw data: "startDate": "2024-09-09T19:32:00.308-0400", "eventType": "segment", "eventTypeInt": 7, "endDate": "2024-09-09T19:37:56.135-0400" }, { "startDate": "2024-09-09T19:32:00.308-0400", "eventType": "segment", "eventTypeInt": 7, "endDate": "2024-09-09T19:41:08.476-0400" },``` // Here's an example of where the second segment start time falls in side the first segments startDate and endDate "startDate": "2024-09-09T19:54:22.658-0400", "eventType": "segment", "eventTypeInt": 7, "endDate": "2024-09-09T19:59:41.215-0400" }, { "startDate": "2024-09-09T19:58:44.624-0400", "eventType": "segment", "eventTypeInt": 7, "endDate": "2024-09-09T20:07:23.216-0400"

I noticed last night that workouts I have been recording on my main carry device running 17.6.x have not been syncing to my beta devices running iOS 18 RC, iPadOS 18 RC and watchOS 11 RC. All devices are using the same Apple Account and I have iCloud enabled for Health data. The iPad running the RC has the syncing enabled in Profile. Is anyone else experiencing health data not propagating to the 18.x devices? Some of data exists on all devices but not all. For good measure I left the device unlocked on the health app last night for a long period of time to let it do its thing. This morning the data still hadn't propagated. I disabled and reenabled the synchronization on my iPad having chosen to delete all samples when disabling it. Hopefully all of my data dating back to the first Apple Watch in 2014 restores. FWIW my data set according to iCloud settings my health dataset is just shy of 650 MB.

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!

Good evening, when I use the automatic export feature from my iPhone, it successfully exports data. When reading the Export.xml file it is dispayed completely, with about 3 mio lines. When I check the file I see, that a lot of data is missing. E.g. the iPhone dispays the heart rates for several exercises (from last year), which don't have any correspondence in the export.xml file. Current exercises have. I am a developer myself and parsed all files without any error. My iPhone has enough free space (200GB or so) and iCloud has more than a TB free. Internet is connected via 1GBit line, WLAN with 800MBit and everything runs smooth. I would like to get a COMPLETE export of all the health data, without having to write a program on my own to accomplish this. Thank you. /C

Finally at last Apple Health supports saving .distancePaddleSports, .distanceCrossCountrySkiing, .distanceRowing, .distanceSkatingSports, and much more. The backstory. In the land of 10,000 lakes, there hasn't been a way to save 'canoe' or 'kayak' distance and I've been asking for it for years. Thank you health team for adding it this year! FB7807993 - Add HKQuantityTypeIdentifier.paddleDistance for canoeing, kayaking, etc type workouts (June 2020) Prior we could just save the totalDistance to a workout, but since the HKWorkout initializers were deprecated we no longer have a supported way to save these distances in our workouts. The iOS 18 / watchOS 11 introduction addresses this. If you want to know more why you can't do this in earlier versions you can check these feedback titles: FB10281482 - HealthKit: Deprecation of totalDistance on a workout session of paddleSports breaks apps that used that to save distance to the workout because there is no "paddleDistance" type available to save as sample data (June 2022) FB12402974 - HealthKit: Deprecation of HKWorkout completely breaks support for third party fitness apps from saving non-standard workout distance (June 2023) Great, so there is new support that solves all of these requests and issues for the new version of the OSes. However, the downside is now that there is not much for documentation. Unlike the .runningSpeed and .runningPower introduced in iOS 16 / watchOS 9, none of the new iOS 18 / watchOS 11 types have documentation, at all. To some degree this is understandable, but types from last year still remain undocumented too. Without this information for the data types introduced in both iOS 17/18 and watchOS 10/11 it makes building and integrating with these new types difficult to say the least. We can't make assumptions about anything. Can we get a documentation update for new (and existing) quantity types for when Apple Watch will automatically generate samples? FB14236080 - Developer Documentation / HealthKit: Update documentation for HKLiveWorkoutDataSource typesToCollect for which sample types are automatically collected by watchOS 10 and 11 (July 2024) FB14942555 - HealthKit / Documentation: App Update Release Issue - HKQuantityTypeIdentifiers are missing documentation describing when the system automatically adds data (today) I know that the behavior has changed from release to release for some of these types, so documentation would be based on OS version. If you didn't catch it, watchOS 11 will now associate .cyclingSpeed for cycling workouts both indoor and outdoor. FB12458548 - Fitness: Connected cycling speed sensor did not save samples to health via cycling workout (June 2023 - received reply that only saved for indoor cycling, but not documented otherwise) FB14311218 - HealthKit: Expected outdoor cycling to include .cyclingSpeed quantity type as a default HKLiveWorkoutDataSource type to collect (July 2024) To the other third party fitness apps out there, how are you managing the knowledge of which devices collect which data types on which versions of the OS? Sure, we could look at the HKLiveWorkoutDatSource and inspect the typesToCollect property across a bunch of devices, but again that is trial by error not 'as documented'. Is the behavior of simulators guaranteed to match the behavior of real devices? Maybe, but also maybe not. Fingers crossed for a nice documentation update to spell out all of the behavioral details. Apple folks / DTS, many of the above feedbacks are addressed and I plan to update or close them after the releases this fall. Some are still outstanding. P.S. I hope that .paddleSports gets deprecated and split into individual activity types like skiing did years ago. Their MET scores are different according to the research on the physical activity compendium site. FB7807902 - Split HKWorkoutActivityType.paddleSports into their own activity types (June 2020)

I’m trying to use BGProcessingTaskRequest to fetch step data in the background and send it. However, when I combine BGProcessingTaskRequest, HKObserverQuery, and healthStore.enableBackgroundDelivery, the results sometimes return zero. When I don’t schedule the BGProcessingTaskRequest, the data retrieved using HKObserverQuery and HKSampleQueryDescriptor is correct. // Register Smart Walking Sync Task func registerSmartWalkingSync() { #if !targetEnvironment(simulator) BGTaskScheduler.shared.register(forTaskWithIdentifier: BGTaskIdentifier.smartwalking.rawValue, using: nil) { task in guard let task = task as?

Heya, I'm currently building out my own application for tracking my health information, and I'm hoping to collect my historical data from Apple Health. Sadly, it would appear that certain things I wish to export don't appear in the export.xml file. Some of the things that I would expect to find in the export.xml file, that do not currently appear, are as follows: More data about my medications, currently I can only export a list of my medications, its not possible to export data such as when what medication was taken. Logged emotions; there is currently no support for this (that I can find). Would appreciate some insight into this.

Like my post title? I'm having issues getting my app accepted by the app store. I keep getting the message: Guideline 2.5.1 - Performance - Software Requirements Your app's binary includes references to HealthKit components, but the app does not appear to include any primary features that require health or fitness data. I don't have healthkit implemented anywhere in my app. I sifted through my app and: Healthkit is not implemented in my infoplist There are no HK imports My app doesn't reveal any references to "Health Kit" when I do a project wide search. The only thing I can think of is that there's an issue with my use of firebase. I'm wondering if I somehow inserted healthkit functionality in to firebase accidentally. Has anyone else had this problem before? If so, how did you solve it? Also. How do you rid of healthkit functionality or references to healthkit within firebase?

Hi! I've added the code of the multidevice workout app from Apple to my app and I found some issues that I cannot see on the sample app. In my app, to pause or end the workout from the watch, the iOS companion app has to be opened or at least on background, but never closed. What I'm doing wrong?

Hi All, I am posting this to get some help on fetching Water intake data from Health Kit. I have done (following a similar approach, and perfectly working) the fetch of the user weight, but for the water, somehow, I always receive back 0 samples. I went to the Health App, added few entries (in different days) for the water intake, under the food sections. Then, I use the following snippet to read the values, but I always have 0 values back. What I am doing wrong? let type = HKQuantityType(.dietaryWater) let samplePredicate = HKSamplePredicate.sample(type: type, predicate: nil) // Create the descriptor. let descriptor = HKSampleQueryDescriptor( predicates: [samplePredicate], sortDescriptors: [SortDescriptor(\.endDate, order: .reverse)]) let results = try await descriptor.result(for: hkHealthStore) The results variable is always 0 elements. What I am doing wrong? PS: The permissions are checked and correctly given for this: HKQuantityType(.dietaryWater)

My iOS app has a correctly configured HealthKit integration. It successfully delivers all samples and data to HealthKit. For every workout sent to HealthKit, I can see the duration, workout name, calories, and other details. However, the app icon is missing. My project uses the Single Size setting for the app icon in the XCAssets folder. The app is available in the App Store in some regions. What can I do to fix this issue? The problem persists regardless of whether the device is running iOS 17 or 18.

In my app im able to get the live heart rate when app is in foreground. When app is in background/ locked condition live heart rate is not fetched. How to get live heart rate frequently.
