Has anyone had success using the HKWorkoutRouteBuilder in conjunction with the new iOS support for HKLiveWorkoutBuilder? I was running my watchOS code that worked now brought over to iOS and when I call insertRouteData the function never returns. This happens for both the legacy and closure based block patterns. private var workoutSession: HKWorkoutSession? private var workoutBuilder: HKLiveWorkoutBuilder? private var serviceSession: CLServiceSession? private var workoutRouteBuilder: HKWorkoutRouteBuilder? private func startRouteBuilder() { Task { @MainActor in self.serviceSession = CLServiceSession(authorization: .whenInUse) self.workoutRouteBuilder = self.workoutBuilder?.seriesBuilder(for: .workoutRoute()) as? HKWorkoutRouteBuilder self.locationUpdateTask = Task { do { for try await update in CLLocationUpdate.liveUpdates(.fitness) { if let location = update.location { self.logger.notice(#function, metadata: [ "location": .stringConvertible(location) ]) try await self.workoutRouteBuilder?.insertRouteData([location]) self.logger.notice("Added location") } } } catch { self.logger.error(#function, metadata: [ "error": .stringConvertible(error.localizedDescription) ]) } } } } I did also try CLLocationManager API with delegate which is what my current watch code uses (a bit old). Same issue. Here is what I've found so far: If the workout session is not running, and if the builder hasn't started collection yet, inserting route data works just fine I've tried different swift language modes, flipped from main actor to non isolated project settings (Xcode 26) Modified Apple's sample code and added location route building to that and reproduced the error, modified sample attached to feedback This issue was identified against Xcode 26 beta 2 and iPhone 16 Pro simulator. Works as expected on my iPhone 13 Pro beta 2. FB18603581 - HealthKit: HKWorkoutRouteBuilder insert call within CLLocationUpdate task never returns

Hi, i'm trying to get the number of step counts a person has taken. I decided to pull the data from health kit and the number of steps are incorrect. Come to find out apple health recommends an app called pedometer++ for the number of steps counted and after testing I realized that they are getting the correct number of steps a person is taking. How can I pull the correct number of steps a person has taken? I want to be able to merge the data from watch and phone to make sure we are getting the correct number of steps but not double counting the steps either. any guidance on this would be appreciated! Here's the code snippet that i'm using right now: permissions: { read: [AppleHealthKit.Constants.Permissions.StepCount], write: [], }, }; AppleHealthKit.initHealthKit(permissions, error => { if (error) { console.log('Error initializing HealthKit: ', error); return; } else { dispatch(setAllowHealthKit(true)); getHealthKitData(); console.log('HealthKit initialized successfully'); } }); const getHealthKitData = async () => { try { const today = new Date(); const options = { startDate: new Date(today.setHours(0, 0, 0, 0)).toISOString(), endDate: new Date().toISOString(), }; const steps = await new Promise((resolve, reject) => { AppleHealthKit.getStepCount(options, (error, results) => { if (error) reject(error); resolve(results?.value); }); }); setStepsCount(steps); } catch (error) { console.error('Error fetching HealthKit data:', error); } };

I'm reading hourly statistics from HealthKit using executeStatisticsCollectionQuery (code below). Expectation What I expect is to get back the list with one row per hour, where each hours has the same cumulative sum value. Actual result In results, first hour always contains less calories than next hours, which all have the same value. Example: Start: 2025-06-02T00:00:00+03:00, anchor: 2025-06-02T00:00:00+03:00, end: 2025-06-02T12:00:00+03:00 🟡 2025-06-02T00:00:00+03:00 Optional(50.3986 kcal) 🟡 2025-06-02T01:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T02:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T03:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T04:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T05:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T06:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T07:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T08:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T09:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T10:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T11:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T12:00:00+03:00 Optional(14.0224 kcal) As you can see, here we have 2025-06-02T00:00:00+03:00 Optional(50.3986 kcal) Now, if I add one more hour to the request (from beginning of time window), the same hour has proper calories count, while newly added hour, has wrong value): 2025-06-01T23:00:00+03:00, anchor: 2025-06-01T23:00:00+03:00, end: 2025-06-02T12:00:00+03:00. 🟡 2025-06-01T23:00:00+03:00 Optional(50.3986 kcal) 🟡 2025-06-02T00:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T01:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T02:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T03:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T04:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T05:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T06:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T07:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T08:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T09:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T10:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T11:00:00+03:00 Optional(64.421 kcal) 🟡 2025-06-02T12:00:00+03:00 Optional(14.0224 kcal) And now first hour of the day, magically has more calories burned: 2025-06-02T00:00:00+03:00 Optional(64.421 kcal) I suspect similar things happen with other quantity types, but haven't yet found a way to reproduce it. Am I doing something wrong or is it a bug in HealthKit? Code let anchorDate = startDate let predicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: [.strictStartDate]) healthStore.executeStatisticsCollectionQuery( quantityType: .basalEnergyBurned, quantitySamplePredicate: predicate, options: [.separateBySource, .cumulativeSum], anchorDate: anchorDate, intervalComponents: DateComponents(hour: 1), initialResultsHandler: { statistics, error in if let error = error { log(.error, "Error retrieving steps: \(error.localizedDescription)") continuation.resume(throwing: SpikeException("Error retrieving steps: \(error.localizedDescription)")) return } if let statistics { let f = ISO8601DateFormatter() f.timeZone = TimeZone.current for s in statistics { log(.debug, "\(f.string(from: s.startDate)) \(s.sumQuantity())") } } continuation.resume(returning: statistics ?? []) } )

When I set the distanceFilter = 5 (5 meters) in the GPS CLLocationManager I can't display the workout routes in the Apple Fitness app after writing the recorded GPS data to HealthKit via HKWorkoutRouteBuilder. The smaller distanceFilter, Fitness will displays the route. Should I consider setting up a small distanceFilter when developing a workout app on watchOS?

Hello everyone, my app is designed to help people sleep. It has been rejected multiple times due to issues with version 1.4.1 during the submission process. However, the app simply evaluates users’ insomnia and anxiety status based on their responses to questions and provides some relaxation methods. It does not involve any medical-related content. The reviewer provided screenshots of the assessment results page and some relaxation techniques. How should I handle this issue?

I am very happy to see that HealthKit with OS26 is bringing HKLiveWorkoutDataSource to iOS and iPadOS. I have been replicating a similar type for the last several years for users that only have an iPhone. I did notice that the data types that the different platform data sources collect automatically is different. That makes sense if you think exclusively about what the device can actually capture. Bluetooth HRM is the only Bluetooth SIG profile that is out-of-the-box supported for Apple Health on iOS and iPadOS (right?). Whereas watchOS 10 got all of the cycling sensors (woohoo!). It would be great if the types to collect were the same across platforms even if the device couldn't collect the data now, because then in the future when / if new sensor support is added, it will be transparent to developers. Fantastic. Easier life as an indie / third party developer. At least that is the idea. And yes, I know I can also write Core Bluetooth code and roll my own SIG implementation for the cycling profiles, but Apple already has this code in one os, 'just copy it, it will be easy'. I know that isn't the reality especially against the new ASK framework, but one can hope and dream right? Imagine how many more apps would contribute that data if it was supported out of the box. An alternative, GitHub is a great place for Apple to share their Core Bluetooth implementation of the SIG profiles :). Just another thought. Here are some feedbacks related to this: FB17931751 - HealthKit: Add built-in support for cycling sensors on iOS and iPadOS - copy paste the code from watchOS.

I was wondering which is the preferred way to send a lot of data from sensors of the apple watch to server. It is preferred to send small chucks to iphone and then to server or directly send bulk data to server from watch. How does it affect battery and resources from watch ? Are there any triggers that I can use to ensure best data stream. I need to send at least once a day. Can I do it in background or do I need the user to have my app in the foreground ? Thank you in advance

Hi everyone, I'm building a health-focused iOS and watchOS app that uses WatchConnectivity to sync real-time heart rate and core body temperature data from iPhone to Apple Watch. While the HealthKit integration works correctly on the iPhone side, I'm facing persistent issues with WatchConnectivity — the data either doesn't arrive on the Watch, or session(_:didReceiveMessage:) never gets triggered. Here's the setup: On iPhone: Using WCSession.default.sendMessage(_:replyHandler:errorHandler:) to send real-time values every few seconds. On Apple Watch: Implemented WCSessionDelegate, and session(_:didReceiveMessage:) is supposed to update the UI. Both apps have WCSession.isSupported() checks, activate the session, and assign delegates correctly. The session state shows isPaired = true and isWatchAppInstalled = true. Bluetooth and Wi-Fi are on, both devices are unlocked and nearby. Despite all this, the Watch never receives messages in real-time. Sometimes, data comes through in bulk much later or not at all. I've double-checked Info.plist configurations and made sure background modes include "Uses Bluetooth LE accessories" and "Background fetch" where appropriate. I would really appreciate guidance on: Best practices for reliable, low-latency message delivery with WatchConnectivity. Debugging steps or sample code to validate message transmission and reception. Any pitfalls related to UI updates from the delegate method. Happy to share further details. Thanks in advance!

I have FB12696743 open since July 21, 2023 and this happened again today. I get home at approx 10 mins after the hour, walk appox 50 ft across my yard, up 5 steps into my house, let the dog out and pace on my deck watching the dog, go back in the house walk around the kitchen while preparing dinner. A total of about 200 ft. I sit down about 35 past the hour and start to eat and at 10 mins to the next our and I get the reminder to stand. On the other side I wake up at 5 mins to hour. Walk 8 steps to the bathroom and successfully achieve the stand for that hour. WHY!?!?!? 😁🤣

I want to know , how many days will the data of health stays in apple watch . For example, I have not synced the watch with iPhone for two weeks . Then When I synced it , I am only able to see the last week data on iPhone of the watch . Is it true ?

For a given date, there are discrepancies between the step counts obtained from HealthKit and those displayed in the Health app. Is it possible for such discrepancies to occur even if step counts are not manually entered and multiple devices are not being used?

We are working on the health related application and use apple health kit to sync the data from different devices like watches or ring. We are targeting oura ring to get sleep and other parameters data. We are able to sync the data from oura for all other parameters (like pulse, respiratory rate, blood pressure, etc..) other than sleep. Surprisingly, sleep data that comes through other devices is syncing as expected from the health kit. We are even getting the data which is added manually in health kit. The only sleep data not syncing is from oura. Can we get a document or any kind of help to sync the data from oura in to our application using health kit?

读取是不是解析 metadata 的对应键来获取值对吧～但我看了相关开发文档好像没找到这个的键是什么～于是也没法写入到对应的，现在只能自定义键来进行写入 但是这样写入后无法显示在心情下方的影响因素后面～ 这个 key 是没公开的吗还是说我方法弄错了～请各位大大指教

Based on Cooordinate with the companion app in this article by Apple https://developer.apple.com/documentation/healthkit/running-workout-sessions if a workout were to be started on the iPhone companion app but with no Watch available, given HKLiveWorkoutBuilder not available in iOS, does the iPhone app need to implement it's own workout tracking such as a timer for counting the elapsed time and location updates for distance and GPS tracking? If so in an instance where a paired Apple Watch were to exist and the workout is continued in the Watch app should the iPhone companion app stop this custom workout tracking and revert to the mirrored workout from the Watch to ensure accurate and synchronised data between the apps?

In the fitness app under iOS 18, the location of all workouts is displayed on a small map. For workouts with routes, I can already successfully read out the route and thus also determine the starting point. So that works. For indoor workouts such as yoga or indoor rowing, the exact location is also displayed in the fitness app. I would now also like to read out this location for these indoor workouts in my app. Does anyone know how to do this?

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?

Hello, I’m developing an iOS app that works with sleep data from Apple Watch via HealthKit. I would like to clarify the following: How can an iPhone app detect when a sleep session ends on the Apple Watch? When is sleep data typically written to the HealthKit store on iPhone after sleep ends? Is it immediately after wake-up, or does it depend on certain conditions (e.g., watch charging, connectivity)? Understanding the timing and mechanism of sleep data synchronization is crucial for our app to process accurate and timely health information. Thank you for your assistance.

Hi, I’m currently working on an app that utilizes sleep data from HealthKit to provide users with meaningful insights about their sleep. To ensure a smooth user experience, I’d like to understand when sleep data collected by the Apple Watch is saved to the HealthKit store and when it gets synced to the iPhone. Ideally, I want to fetch sleep data right after the user wakes up and opens our app. However, to do this reliably, I need to know the timing of how and when this data becomes available in the iPhone’s HealthKit store. I’ve looked through the official documentation and relevant WWDC sessions but couldn’t find clear information on this topic. If anyone has insights or experience with how and when the Apple Watch syncs HealthKit data—especially sleep records—to the iPhone, I’d greatly appreciate your input. Thanks!

The WatchOS developer is not allowed to obtain healthKit permission status. The result is always unauthorized (either by clicking the dot/cross in the upper left corner or by turning on all Health, on some, off all). WatchOS 开发获取 healthKit 的权限状态authorizationStatus不准。结果始终都是未授权（无论是点击左上角的点叉号还是开启全部健康项开关，开启部分，关闭所有），怎么处理？
