I'm developing a single target watchOS app that obtains HealthKit information. I have the "Background Delivery" option checked under "Signing & Capabilities" for the watch target. The app does HKObserverQueries in the foreground that work as I would expect. But when I click the Digital Crown to return to clock face, the HKObserverQuery activity stops. I'm using Xcode 15.4, on Mac 14.5 and a Apple Watch Series 4 running 10.5.

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 have a strange situation and I'm not sure where else to post this. Our app's domain (or at least its API hostname in the domain) resolves to something different only inside of Apple's network. I was able to get an Apple employee to verify this by resolving the API hostname while on Apple's corporate network and it resolves to an IP that is in Apple's 17.0.0.0/8 network, but everywhere else resolves to the normal IPs. Our domain's DNS is provided by Cloudflare and they are not doing anything special for Apple's network. This is causing problems during App Review because the app is trying to reach our API to log in and instead is being routed to an IP in Apple's network, so it fails SSL validation and presents an error dialog. App Review is then claiming our app doesn't work and rejecting it. This is an app that has been in the App Store for over a decade and gone through countless app reviews. App Review was of no help resolving this and I don't know where else to turn. How can I find out why our domain is being rerouted inside of Apple and get this fixed?

I need to be able to create and store a HeartbeatSeries for a given time-period from an Apple Watch, to then retrieve that data from HealthKit to be processed. I have working code which allows me to begin a workout session, which is being used to determine how long a session has been running for. I also have working code for retrieving HeartbeatSeries data from HealthKit. The issue is that no HeartbeatSeries data is being stored into HealthKit as a result of the workout session running. Whether that session is running for as little as 30 seconds or as long as 20 minutes, nothing is stored. However, when I use the the Apple "Meditation" app (formerly known as "Breathe"), I can query HealthKit afterwards and retrieve a list of individual heartbeat timings during that 2 minute period. Therefore, it IS possible to store a HeartbeatSeries from within an app on the Apple Watch. What I would like to know is, how can I use the pulse sensor built-in to the Apple Watch to be able to record a HeartbeatSeries similar to how the Meditation app does it.

My research group is using watch sensors (accelerometers, gyroscopes) to track wrist motion to detect and measure eating. https://cecas.clemson.edu/ahoover/bite-counter/ We are running an HKWorkoutSession on the watch so that the app can run for an extended period of time (up to 12 hr) and continue to sense and process motion data. Our app is adding to the activity rings, making it look like the user is exercising the entire time our app is running. Is there a method to prevent our app from contributing to the activity ring measures?

I am experiencing a critical issue with HealthKit authorization in iOS 18.5 where requestAuthorization() calls are immediately denied without showing the user permission dialog. Problem Description: HealthKit authorization requests immediately return .sharingDenied status No system permission dialog is displayed to the user Authorization status changes from .notDetermined to .sharingDenied in <0.1 seconds This occurs for all HealthKit data types (step count, heart rate, sleep analysis, etc.) Technical Details: iOS Version: 18.5 (22F76) Xcode Version: 16F6 Device: iPhone (tested on both simulator and physical device) Bundle IDs tested: com.hereforyou.test2024, com.hereforyou.app Entitlements: com.apple.developer.healthkit = true Code Implementation: let healthStore = HKHealthStore() let stepType = HKObjectType.quantityType(forIdentifier: .stepCount)! // Status before request: .notDetermined try await healthStore.requestAuthorization(toShare: [], read: [stepType]) // Status after request: .sharingDenied (immediate, <0.1 seconds) Evidence this is not a code issue: Other HealthKit apps from App Store work correctly on the same device Proper entitlements are configured and verified HKHealthStore.isHealthDataAvailable() returns true Same code worked in previous iOS versions Multiple Bundle IDs tested with same result Expected Behavior: System should display HealthKit permission dialog allowing user to grant/deny access Actual Behavior: Authorization is immediately denied without user interaction Steps to Reproduce: Create new iOS app with HealthKit entitlements Call requestAuthorization() for any HealthKit data type Observe immediate denial without permission dialog Is this a known issue in iOS 18.5? Are there any workarounds or timeline for a fix? Best regards

Are there any HealthKit related changes to be aware of in the new update that enables SPO2 / Blood Oxygen Saturation measurements on certain Apple Watch models within the US? I’m aware of processing happening on the phone…. But beyond that: Does this mean values are then saved to Apple Health? Do these models still take background SPO2 measurements in the same way as other models do? Are these values then visible in third party iOS apps as normal through HealthKit? Do these values sync back to the paired Apple Watch HealthKit store for third party apps to access on the Watch? For reference I have an iOS and WatchOS app that, amongst other features, provides the ability to see your SPO2 values in the Watch app, complications and in the iOS app.

Hi! I am using the HKAnchoredObjectQuery to first get a snapshot of the initial results, and then trigger an updateHandler. I need to handle the initial results and the updates separately, which is why I implemented two completions. When I test the code, it works for a while. New and deleted samples trigger the updateHandler. However, after a while there appears an error: [connection] nw_read_request_report [C2] Receive failed with error "Software caused connection abort" Followingly, the updateHandler will stop getting triggered when I add updates in Apple health. Anyone have experience with this? func getMostRecentSample(for sampleType: HKSampleType, anchorKey: String, completion: @escaping (HKQuantitySample?, Error?) -> Swift.Void, updateHandler: @escaping (HKQuantitySample, Error?) -> Swift.Void) {     // If it is the first initialization, anchor is passed as nil     var anchor: HKQueryAnchor? = nil // Check for previous saved anchor in userdefaults     if UserDefaults.standard.object(forKey: anchorKey) != nil {       let data = UserDefaults.standard.object(forKey: anchorKey) as! Data       do {         guard let newAnchor = try NSKeyedUnarchiver.unarchivedObject(ofClass: HKQueryAnchor.self, from: data) else {           print("Could not parse anchor to HKQueryAnchor type")           return         }         anchor = newAnchor       } catch {         print("Error retreiving anchor from UserDefaults")       }     }     let query = HKAnchoredObjectQuery(type: sampleType,                      predicate: nil,                      anchor: anchor,                      limit: HKObjectQueryNoLimit                       ) { (query, samplesOrNil, _, newAnchor, errorOrNil) in       guard let samples = samplesOrNil as?

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)

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)

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'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.

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?

In this link, Apple states we can know when a user is in bed vs sleeping and compare their quality of sleep by it. Only, in iOS 18, Apple no longer reports inBed time samples for the Apple Watch. I get why they stopped doing this for the phone, but why the watch? Bug? My app was using the inBed times for this very purpose and now only works for Garmin and Oura who still report inBed times. https://developer.apple.com/documentation/healthkit/hkcategoryvaluesleepanalysis

We currently use the HKCategoryValueMenstrualFlow enum to determine the type of menstrual flow: light, medium, etc. a user is having. We also use this enum in determining if it's an actual period day. The Problem I see HKCategoryValueMenstrualFlow was recently deprecated but has not been replaced by another data type. Are there plans to replace/update it with another data type? When or at what point in the future will this deprecation cause a problem in my code?

I've been trying to figure out what the bare minimum is required for HKWorkoutBuilder to create a workout that adds time the appleExerciseTime. I couldn't find the documentation for this. This is my code so far. func createWorkoutSample( expectedActiveEnergyData: [Double], expectedExerciseMinutesData: [Double], calendar: Calendar, startDate: Date ) async throws -> [HKSample] { var testData: [HKSample] = [] let workoutConfiguration = HKWorkoutConfiguration() workoutConfiguration.activityType = .running workoutConfiguration.locationType = .outdoor let results = try await withThrowingTaskGroup(of: HKSample?.self) { group in for (index) in 0..<expectedActiveEnergyData.count { guard let date = calendar.date(byAdding: .day, value: index, to: startDate) else { continue } group.addTask { let builder = HKWorkoutBuilder( healthStore: self.manager.healthStore, configuration: workoutConfiguration, device: .local() ) let endDate = date.addingTimeInterval(expectedExerciseMinutesData[index] * 60) try await builder.beginCollection(at: date) let energyType = HKQuantityType.quantityType( forIdentifier: .activeEnergyBurned )! let energyQuantity = HKQuantity( unit: HKUnit.kilocalorie(), doubleValue: expectedActiveEnergyData[index] ) let energySample = HKQuantitySample( type: energyType, quantity: energyQuantity, start: date, end: endDate ) return try await withCheckedThrowingContinuation { continuation in builder.add([energySample]) { (success, error) in if let error = error { continuation.resume(throwing: error) return } builder.endCollection(withEnd: endDate) { (success, error) in if let error = error { continuation.resume(throwing: error) return } builder.finishWorkout { (workout, error) in if let error = error { continuation.resume(throwing: error) return } continuation.resume(returning: workout) } } } } } } for try await workout in group { if let workout = workout { testData.append(workout) } else { print("Skipping nil workout result.") } } return testData } print("Total samples created: \(results.count)") return results } When I query appleExerciseTime, there are no results. I've looked at the HKWorkoutBuilder documentation, and most of the information expands on adding samples related to the deprecated HKWorkout.

Is there documentation on how to read workout effort scores from a HealthKit workout? I'm interested in reading workoutEffortScore and estimatedWorkoutEffortScore. I have not been successful trying to read them using the same method that I do other workout HKQuantityTypes (heartRate, stepCount, etc). I'm using Swift and I do have authorization for those types requested and granted. I have found documentation on setting these values (https://developer.apple.com/forums/thread/763539) but not reading them. Thank You
