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？

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?

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?

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.

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?

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

I'm using following filters to fetch swimming activities from HealthKit. For some users it fetches all workouts (pool && open water) but for other it skips some open water activities. See screenshot, all those swimming activities are not fetched by following code. let startDate = Calendar.current.date(byAdding: .month, value: -1, to: Date())! let endDate = Date() let swimmingPredicate = HKQuery.predicateForWorkouts(with: .swimming) let timePredicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: .strictStartDate) let predicate = NSCompoundPredicate(andPredicateWithSubpredicates: [swimmingPredicate, timePredicate]) let query = HKSampleQuery(sampleType: .workoutType(), predicate: predicate, limit: HKObjectQueryNoLimit, sortDescriptors: [.init(keyPath: \HKSample.startDate, ascending: false)], resultsHandler: { [weak self] query, samples, error in ... Could someone help with ideads what is missing in this case?

Hello, What is the best practice for sending customized workouts to the Apple Watch. For example, sending a running workout that entails: Run 1 mile at 8:00/mile Walk 2 minutes Run 2 mile at 7:00/mile ---- Walk 2 minutes ---- Repeat 2x Run 1 mile at 8:00/mile Any documentation or sample codes would be amazing. Thank you

Hello everyone, Ujjwal here, founder and CEO of a new iOS app in the mental wellness space. Our mission is to provide accessible, AI-driven support for individuals dealing with anxiety, depression, and loneliness. From the very beginning, this has presented us with a unique and critical challenge: How do we effectively market an app to reach those who need it most, while upholding the absolute highest standards of user privacy? We've built our app, ThunDroid, with a "privacy-by-design" philosophy. We leverage on-device processing for our core AI features, utilize end-to-end encryption, and have proudly integrated 'Sign in with Apple' to maximize user anonymity. We believe these are not just features, but ethical obligations to our users, especially given the nature of the data they trust us with. The challenge, however, arises in marketing. This leads us to focus on mission-driven, organic marketing, but it's a slower path to reaching users who might be in immediate need of support. This brings me to my question for this knowledgeable community. What best practices or creative strategies have you found effective for marketing applications? I appreciate any insights or experiences you're willing to share as we continue to grow ThunDroid responsibly. Thank you for your time and consideration.

I am developing a running training app that coaches can use to create interval workout plans. I can use HKWorkout to get information about Splits similar to that in Fitness app, but I can't get information about Intervals. My idea is to show interval details when users view their completed custom interval workout plans. Can I use Healthkit (or another feasible method) to get the actual distance or time of exercise in intervals workout ? (I know the workoutPlan property, but it doesn't reflect the segments of a real interval training workout.) Any insights or suggestions would be greatly appreciated! Thanks in advance!

I'm developing a watchOS nap app that detects when the user falls asleep by monitoring heart rate changes. == Technical Implementation == HKWorkoutSession (.mindAndBody) for background execution HKAnchoredObjectQuery for real-time heart rate data CoreMotion for movement detection == Battery Considerations == Heart rate monitoring ONLY active when user explicitly starts a session Monitoring continues until user is awakened OR 60-minute limit is reached If no sleep detected within 60 minutes, session auto-ends (user may have abandoned or forgotten to stop) App displays clear UI indicating monitoring is active Typical session: 15-30 minutes, keeping battery usage minimal == The Problem == HKWorkoutSession affects Activity Rings during the session. Users receive "Exercise goal reached" notifications while resting — confusing. == What I've Tried == Not using HKLiveWorkoutBuilder → Activity Rings still affected Using builder but not calling finishWorkout() (per https://developer.apple.com/forums/thread/780220) → Activity Rings still affected WKExtendedRuntimeSession (self-care type) (per https://developer.apple.com/forums/thread/721077) → Only ~10 min runtime, need up to 60 min HKObserverQuery + enableBackgroundDelivery (per https://developer.apple.com/forums/thread/779101) → ~4 updates/hour, too slow for real-time detection Audio background session for continuous processing (suggested in https://developer.apple.com/forums/thread/130287) → Concerned about App Store rejection for non-audio app; if official approves this technical route, I can implement in this direction Some online resources mention "Health Monitoring Entitlement" from WWDC 2019 Session 251, but I could not find any official documentation for this entitlement. Apple Developer Support also confirmed they cannot locate it? == My Question == Is there any supported way to: Monitor heart rate in background for up to 60 minutes WITHOUT affecting Activity Rings or creating workout records? If this requires a special entitlement or API access, please advise on the application process. Or allow me to submit a code-level support request. Any guidance would be greatly appreciated. Thank you!

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!?!?!? 😁🤣

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?

I’m trying to associate heart rate (HR) data with a mindfulness session (HKCategoryTypeIdentifier.mindfulSession) in HealthKit, but I can’t find any documentation on how to do this. I’ve seen third-party apps (like Medito) successfully log HR within Mindful Minutes, even when the session takes place on an iPhone (not an Apple Watch). However, when I try saving HR in the metadata, it does not appear in the Health app's Mindful Minutes section. Code snippet: func logMindfulnessSession(start: Bool, heartRate: Double? = nil) { let mindfulType = HKCategoryType.categoryType(forIdentifier: .mindfulSession)! let now = Date() let endTime = now.addingTimeInterval(Double(selectedDuration)) var metadata: [String: Any]? = nil if let hr = heartRate { let heartRateUnit = HKUnit.count().unitDivided(by: HKUnit.minute()) let hrQuantity = HKQuantity(unit: heartRateUnit, doubleValue: hr) metadata = ["heartRate": hrQuantity] // ❓ Is there a correct key for HR? } let sample = HKCategorySample( type: mindfulType, value: 0, start: now, end: endTime, metadata: metadata ) healthStore.save(sample) { success, error in if let error = error { print("HealthKit session save error: \(error.localizedDescription)") } else { print("Mindfulness session saved successfully.") if let hr = heartRate { print("Saved with HR: \(hr) BPM") } } } } Questions: What is the correct metadata key for associating heart rate with a mindful session? Does HealthKit require a specific format (e.g., HKQuantitySample) for HR? 0 Are there additional permissions needed to allow HR to appear in Mindful Minutes? Does HR need to be stored separately in HKQuantityTypeIdentifier.heartRate, and if so, how do third-party apps ensure it appears in the same entry as the mindful session? thank you!

I am developing a React Native app for a health monitoring device that connects via Bluetooth and streams live data on iOS. To ensure the uniqueness of the device, I initially planned to use the MAC address. However, I discovered that iOS does not provide access to the original MAC address due to privacy restrictions. Is there an alternative approach to uniquely identifying a Bluetooth device in iOS? I need a reliable way to distinguish devices while maintaining secure and stable connections. Any insights or best practices on handling this in iOS would be greatly appreciated. Looking forward to hearing your suggestions! If anyone has experience with handling Bluetooth device uniqueness on iOS, please share your insights. Thank you!

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!

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.

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 ?

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!
