Hi everyone, I’m developing a health-related mobile app and considering using EAS Update to deliver over-the-air (OTA) updates for JavaScript code and assets. Before implementing this, I want to ensure that this approach complies with Apple App Store policies, especially given the sensitivity of health-related apps. Here are my concerns: Does using EAS Update (OTA) align with Apple’s guidelines regarding app updates and dynamic behavior changes? Are there specific rules or restrictions for health apps using OTA updates that I should be cautious of? Could this approach be flagged as violating Apple’s policies on app integrity, especially those requiring updates to go through the App Store review process? I’d greatly appreciate any insights, advice, or references to Apple’s official documentation regarding OTA updates for apps distributed through the App Store. Thanks in advance for your help!

Hello, I am building a workout app that has an option to add segments to differentiate different stages of the training session. Segments are added the following way: func saveSegment(eventType: HKWorkoutEventType, startDate: Date, endDate: Date, inSeg: Int) async throws { let dateInterval = DateInterval(start: startDate, end: endDate) let event = HKWorkoutEvent(type: eventType, dateInterval: dateInterval, metadata: metadata) try await builder?.addWorkoutEvents([event]) } Inside Health -> Workouts -> Show All Data, the segments appear, but in Fitness app there are no segments. The workout is .paddleSports. I thought that maybe the workout type was the problem, but when I start the sessions from the native workout app, segments are added and shown in the Fitness app: In other posts I saw suggested to add an event as .marker instead of .segment, but the result is the same, it does not appear. Is there something I am doing wrong? How can I show the segments into the Fitness app? Another question, I would like to add stroke rate and stroke count to my paddling session, is there a way to add it? Paddle Sports workout was recently introduced and it would be great to have the option to add those values. Thank you in advance. Inaki

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. It will be easy they said (June 2025) FB12323089 - CoreBluetooth / Health / Bluetooth Settings: Add support for cycling sensors announced in watchOS 10 to iOS and iPadOS 17 (June 2023) FB14311218 - HealthKit: Expected outdoor cycling to include .cyclingSpeed quantity type as a default HKLiveWorkoutDataSource type to collect (July 2024) FB14978701 - Bluetooth / HealthKit / Fitness: Expose information about the user specified for Apple Watch paired Cycing Speed Sensor like isConnected and wheelCircumference values (August 2024) FB18402258 - HealthKit: HKLiveWorkoutDataSource should collect same types on iOS and watchOS even if device cannot produce data today (June 2025) FB14236080 - Developer Documentation / HealthKit: Update documentation for HKLiveWorkoutDataSource typesToCollect for which sample types are automatically collected by watchOS 10 and 11 (July 2024) Tangentially related: FB10281304 - HealthKit: Add HKActivityTypes canoeBikeRun and kayakBikeRun (June 2022) FB10281349 - HealthKit: Add HKActivityType walkCanoeWalk and walkKayakWalk (June 2022) FB7807993 - Add HKQuantityTypeIdentifier.paddleDistance for canoeing, kayaking, etc type workouts (June 2020) FB12508654 - HealthKit / Settings / Bluetooth / Workouts: Cycling sensor support doesn't allow for 'bike selection' in use case of multiple bikes and multiple sensors (borrow a bike to ride together) - production usability issue (July 2023)

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 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?

We have working code to fetch step data from HealthKit after requesting the necessary permissions. However, we’ve encountered an issue specific to one device, the iPhone 16 Pro Max. When querying the data, we do not receive a response, and the code enters an infinite loading state without completing the request. The user who is facing this issue has tried logging in on another device, and it works fine. On the problematic device (iPhone 16 Pro Max), the request does not complete. For reference, I’ve included the code below. Resolving this issue is crucial, so we would appreciate any guidance on what steps we can take to troubleshoot or resolve the problem on this specific device. Please note that the device has granted permission to access HealthKit data. static let healthStore = HKHealthStore() static func limitReadFromHealthKitBetweenDates(fromDate: Date, toDate: Date = Date(), completion: @escaping ([HKStatistics]) -> Void) { guard let stepsQuantityType = HKQuantityType.quantityType(forIdentifier: .stepCount) else { return } let ignoreUserEntered = HKQuery.predicateForObjects(withMetadataKey: HKMetadataKeyWasUserEntered, operatorType: .notEqualTo, value: true) let now = toDate var interval = DateComponents() interval.day = 1 var calendar = Calendar.current calendar.locale = Locale(identifier: "en_US_POSIX") var anchorComponents = calendar.dateComponents([.day, .month, .year], from: now) anchorComponents.hour = 0 let anchorDate = calendar.date(from: anchorComponents) ?? Date() let query = HKStatisticsCollectionQuery(quantityType: stepsQuantityType, quantitySamplePredicate: ignoreUserEntered, options: [.cumulativeSum], anchorDate: anchorDate, intervalComponents: interval) query.initialResultsHandler = { _, results, error in guard let results = results else { print("Error returned from resultHandler: \(String(describing: error?.localizedDescription))") return } print(results) var statisticsArray: [HKStatistics] = [] results.enumerateStatistics(from: fromDate, to: now) { statistics, _ in statisticsArray.append(statistics) if statistics.endDate.getddmmyyyyslashGMT == now.getddmmyyyyslashGMT { completion(statisticsArray) } } } healthStore.execute(query) } Please note that the code works on all devices except the problematic one. Could you please guide me on the next steps to resolve this issue?

Good afternoon, I am working on a workout tracking app. So far everything is working as expected. However, I note that when my workout saves and is visible within the Fitness App, the workout duration is displayed rather than the kCal burned. What changes are required to be made in order for this to display the kCal in the list of workouts in Fitness rather than duration? For reference https://developer.apple.com/videos/play/wwdc2021/10009 this was my reference source for workout functionality.

I have a workout app which I am testing on device currently via TestFlight. The generated workout (tennis and indoor) shows in the fitness app with correct HR and duration. However, when I go to my Strava app, it does not show in the list of workouts for importing. (note, activities tracked using the regular tennis mode on the Apple Watch show fine) I have also concurrently reached out to Strava support to see if there's anything they can offer support for. However, does anybody here have any knowledge/experience of the requirement? Or whether this is a limitation of an application deployed via TestFlight? I have a terrible feeling I am chasing ghosts, and it may be a TestFlight limitation for exporting workouts? Thanks

I am writing to address a concern regarding the background permission functionality in my app, which is critical for ensuring user safety as they navigate various terrains. This feature also enables users to smoothly record their navigation tracks for review after their activities. Recently, I've noticed that this functionality is not working as seamlessly as before. Additionally, I observed that the app is not categorized under 'health and fitness'—could reclassifying it improve background activity? Before I delve into a detailed code review, I wanted to check if this issue might be related to sync or settings on the App Store side, such as permission configurations, app updates, or other related factors. Or, is it more likely an issue stemming from the app’s codebase?

I'm dealing with a strange bug where I am requesting read access for 'appleExerciseTime' and 'activitySummaryType', and despite enabling both in the permission sheet, they are being set to 'sharingDenied'. I'm writing a Swift Test for making sure permissions are being granted. @Test func PermissionsGranted() { try await self.manager.getPermissions() for type in await manager.allHealthTypes { let status = await manager.healthStore.authorizationStatus(for: type) #expect(status == .sharingAuthorized, "\(type) authorization status is \(status)") } } let healthTypesToShare: Set<HKSampleType> = [ HKQuantityType(.bodyMass), HKQuantityType(.bodyFatPercentage), HKQuantityType(.leanBodyMass), HKQuantityType(.activeEnergyBurned), HKQuantityType(.basalEnergyBurned), HKObjectType.workoutType() ] let allHealthTypes: Set<HKObjectType> = [ HKQuantityType(.bodyMass), HKQuantityType(.bodyFatPercentage), HKQuantityType(.leanBodyMass), HKQuantityType(.activeEnergyBurned), HKQuantityType(.basalEnergyBurned), HKQuantityType(.appleExerciseTime), HKObjectType.activitySummaryType() ] let healthStore = HKHealthStore() func getPermissions() async throws { try await healthStore.requestAuthorization(toShare: self.healthTypesToShare, read: self.allHealthTypes) } After 'getPermissions' runs, the permission sheet shows up on the Simulator, and I accept all. I've double checked that the failing permissions show up on the sheet and are enabled. Then the test fails with: Expectation failed: (status → HKAuthorizationStatus(rawValue: 1)) == (.sharingAuthorized → HKAuthorizationStatus(rawValue: 2)) HKActivitySummaryTypeIdentifier authorization status is HKAuthorizationStatus(rawValue: 1) Expectation failed: (status → HKAuthorizationStatus(rawValue: 1)) == (.sharingAuthorized → HKAuthorizationStatus(rawValue: 2)) HKActivitySummaryTypeIdentifier authorization status is HKAuthorizationStatus(rawValue: 1) With the rawValue of '1' being 'sharingDenied'. All other permissions are granted. Is there a workaround here, or something I'm potentially doing wrong?

In my WatchOS app I've written the following code to check if my app has access to the user's health data: func isHealthKitAuthorized() -> Bool { let typesToRead: [HKObjectType] = [ HKObjectType.quantityType(forIdentifier: .heartRate)!, HKObjectType.quantityType(forIdentifier: .activeEnergyBurned)!, HKObjectType.quantityType(forIdentifier: .appleMoveTime)!, HKObjectType.quantityType(forIdentifier: .appleExerciseTime)!, HKObjectType.workoutType() ] let typesToShare: Set<HKSampleType> = [ HKObjectType.workoutType(), HKObjectType.quantityType(forIdentifier: .activeEnergyBurned)!, HKObjectType.quantityType(forIdentifier: .heartRate)! ] var isAuthorized = true for type in typesToRead { let status = healthStore.authorizationStatus(for: type) if status != .sharingAuthorized { print("Access denied to: \(type.identifier)") isAuthorized = false } } for type in typesToShare { let status = healthStore.authorizationStatus(for: type) if status != .sharingAuthorized { print("Access denied to: \(type.identifier)") isAuthorized = false } } return isAuthorized } However for the appleMoveTime and appleExerciseTime types their status is returning as 'sharingDenied' (checked by printing the status' rawValue) even though they are authorized on the Watch's settings. This happened both on the simulator and on the Watch itself. Am I doing something wrong?
