I want to insert the medication data which is available from ios 26 from my app to apple health kit. I have tried to get the permission to read and write data but app got crashed while I tried to request that permission. Does apple allow to insert the medication data to apple health kit likewise we are able to add other health and fitness data or not? let healthStore = HKHealthStore() @available(iOS 26.0, *) @objc func requestAuthorization(_ resolve: @escaping RCTPromiseResolveBlock, rejecter reject: @escaping RCTPromiseRejectBlock) { guard HKHealthStore.isHealthDataAvailable() else { print("not available ") return } let doseType = HKObjectType.medicationDoseEventType() let medType = HKObjectType.userAnnotatedMedicationType() healthStore.requestAuthorization(toShare: [doseType], read: [doseType]) { success, error in if let err = error { reject("auth_error", err.localizedDescription, err); return } self.healthStore.requestPerObjectReadAuthorization(for: medType, predicate: nil) { s, e in if let err2 = e { reject("per_obj_auth", err2.localizedDescription, err2); return } resolve(["ok": success && s]) } } }

We are using HealthKit in our app to synchronize step count data. The data is correctly synced with the Health app, but the step count does not appear in the Fitness app (although workout data does). Is there anything developers need to do to synchronize step count data with the Fitness app as well?

Hey everyone I'm working on a health app that's heavily focused on HRV tracking and analysis, and I'm trying to figure out what's actually possible with AirPods Pro 3 from a developer standpoint. The hardware clearly has a much better heart rate sensor than the previous generation, but I'm hitting some walls when it comes to actually accessing the data I need. So here's the situation I'm dealing with: When I query HealthKit for HRV samples, I'm not seeing anything coming from AirPods Pro 3. The device is obviously capable of tracking heart rate continuously during workouts and listening sessions, and from what I've read about the hardware, it should theoretically be able to capture the inter-beat intervals needed for HRV calculation. But either that data isn't being processed on-device, or it's just not being made available through the standard HealthKit data types that third-party apps can access. What I'm really after is either direct HRV metrics (like SDNN, which Apple Watch already provides through HKQuantityTypeIdentifierHeartRateVariabilitySDNN) or even better, access to the raw R-R interval data. With R-R intervals, I could calculate RMSSD, pNN50, and other time-domain and frequency-domain HRV metrics that are super valuable for tracking recovery, autonomic nervous system balance, and stress levels. This would be especially useful since a lot of users wear AirPods during activities when they're not wearing their Apple Watch. Has anyone managed to find a way to pull this data from AirPods Pro 3? Are there any private frameworks or entitlements I should be looking into? Or is this just fundamentally not exposed to developers at the OS level right now? I've gone through the HealthKit documentation pretty thoroughly and haven't found anything that specifically addresses this, but I'm wondering if I'm missing something or if there are any known workarounds. I'm also curious if anyone has heard anything from Apple about future plans to expose this data. It seems like a missed opportunity given how capable the hardware is and how much value developers could provide with access to this physiological data. Would love to hear if anyone else is working on similar features or has insights into the technical limitations here.

Ever since upgrading to OS 26.1, I've noticed that HealthKit anchored object queries seem to be much slower-updating than normal. I was curious if Apple stated anything explicitly changed on this front? I use anchored object queries to update some of the workout metrics that HKLiveWorkoutBuilder doesn't report (like stepCount).

Hi everyone, we’re developing an app that lets users export selected bike rides to the HealthKit ecosystem. We created our app icon using the Apple Icon Composer and referenced the composer file in Xcode. Everything works fine, except that the logo doesn’t appear correctly in the Fitness app. Has anyone experienced this issue or knows how to fix it?

I am the developer of a workout app that allows users to create interval programs (e.g. Warm Up, Fast, Cool Down). It is possible for me to store the data for the intervals along with the workout in the Health system by using WorkoutKit (or any other method)? My aim is to make it so that the Fitness app shows the interval details when users view workouts created by my app. Thanks in advance.

I am developing an iOS application that utilizes running workout data from the iOS Health app / Fitness app via HealthKit, with explicit user permission. Before finalizing the app design, I would like to clarify several technical aspects related to data reliability, manual entry, record modification, and GPS route availability in HealthKit. My questions are as follows: 1. Identifying manually added (non-physical) running workouts When a running workout is created in the Health app without actual physical movement (for example, a workout manually added by the user), is there any metadata, flag, or key in HealthKit that allows developers to distinguish these records from workouts generated through actual motion tracking (iPhone or Apple Watch)? 2. Editing existing running workout records Is it possible for users, or for third-party apps with HealthKit write permission, to edit an existing running workout (e.g., distance, duration, calories) after it has been saved? • If edits are allowed, are the original values preserved in any way, or are they fully overwritten? 3. Detecting modified workout records If a running workout (whether originally auto-recorded or manually created) has been edited after creation, is there any identifier, metadata field, source revision, or versioning mechanism in HealthKit that allows developers to detect that the workout has been modified? 4. Access to GPS route / running path data For outdoor running workouts recorded with location services enabled: • Does HealthKit provide access to GPS route data (running paths / location traces) associated with a workout? • Is this route data accessible to third-party apps with user permission? • Is route data available only for workouts recorded on Apple Watch, or also for iPhone-only recordings? • Is there a way to determine programmatically whether a running workout includes valid GPS route data? The overall goal is to understand whether, when building an app that relies on HealthKit running data, it is technically possible to differentiate motion-based workouts from manually added or edited records, and to assess the availability of route information for outdoor runs. Any clarification or references to official documentation would be greatly appreciated. Thank you

Hello everyone, I’m experiencing a visual issue when dismissing a sheet on iOS 26. I’m using the same implementation shown in the official Apple documentation. While testing, I noticed that some apps do not exhibit this behavior. However, when running this code on iOS 26, the issue consistently occurs. Issue description: The sheet dismisses abruptly A white screen briefly appears for a few milliseconds and then disappears This results in a noticeable visual glitch and a poor user experience I tested the exact same code on iOS 18, where the sheet dismisses smoothly and behaves as expected, without any visual artifacts. Has anyone else encountered this issue on iOS 26? Is this a known bug, or is there a recommended workaround? Any insights would be greatly appreciated. Thank you.

HealthKit background delivery only triggers when charging. I have set step monitoring to hourly frequency. Despite step changes, callbacks fail to arrive after 3-4 hours on battery, but trigger immediately upon connecting power. Observed for 2 days: background updates are only received when charging. The device is not in Low Power Mode, and Background App Refresh is enabled for the app in Settings.

Why can I use background delivery to realize background notifications when I run the app for the first time, but when I delete the app running in the background, and then reopen the app to run it in the background, there will be no background notification when the data changes?

While attempting to read a user’s daily step history spanning backward to the last 7 days, a small but consistent subset of users encounter Error Code 3 with the underlying error description: Error Code 3 "Unable to invalidate interval: no data source available." When this error occurs, we are entirely unable to read their step history. We have received ~10 direct user reports of this within the last couple of weeks.

Hello Apple Developer Support / Community, I would like clarification regarding HealthKit data access behavior when an iPhone is locked. We are building an app that uses: HKObserverQuery enableBackgroundDelivery HKAnchoredObjectQuery Background execution to sync HealthKit data to our server Our specific question is: When the device is locked with passcode/Face ID protection enabled, can an app launched in the background through HKObserverQuery or other background mechanisms reliably access and read HealthKit data? We would like to understand the expected Apple-supported behavior for the following scenarios: If new HealthKit samples are written while the phone is locked, will HKObserverQuery still trigger immediately? If the observer callback is invoked while locked, can HKAnchoredObjectQuery successfully read the new samples? Is HealthKit data inaccessible while locked due to Data Protection / encrypted store behavior? Should developers expect delivery or data reads to be deferred until the user unlocks the device? We are trying to set correct expectations for background syncing and would appreciate official clarification on whether near real-time HealthKit sync is possible while the device remains locked. Relevant documentation mentions HealthKit store encryption, but we would appreciate direct confirmation for production behavior. Thank you.

Hello, I'm experiencing a bug on iOS 26.5 RC1/RC2 where the Blood Pressure option is silently excluded from the HealthKit permission dialog (when requesting HKQuantityTypeIdentifierBloodPressureSystolic and HKQuantityTypeIdentifierBloodPressureDiastolic). This does not reproduce on iOS 26.4.2 or earlier. What happens: When BP types are requested alone, a blank white modal slides up and immediately dismisses — no permission UI is shown. When BP is requested alongside other types, a normal dialog appears for those other types, but Blood Pressure is simply absent from the list. The completion handler returns success = YES, error = nil in both cases, but BP permission is never granted. The result: Settings → Privacy & Security → Health → [app] shows Blood Pressure as requested but not granted getRequestStatusForAuthorizationToShareTypes for the BP types keeps returning ShouldRequest indefinitely HealthKit queries for BP samples return no data Workaround: Manually toggling Blood Pressure to ON in Settings → Privacy & Security → Health → [app name] fixes everything - queries work, notifications fire, and getRequestStatusForAuthorizationToShareTypes correctly returns HKAuthorizationRequestStatusUnnecessary. Environment: Confirmed broken: iOS 26.5 RC1 (23F75) and RC2 (23F77), iPhone 11; iOS 26.5 RC1 (23F73), simulator Confirmed working: iOS 26.4.2 (device), iOS 26.4.1 (simulator) Feedback filed as FB22735935.

Hi, I've had trouble for a while now with HealthKit giving me different values if I make the request on iOS and WatchOS. I am using the exact same method on both with the same parameters but I get vast differences in the results. The code I am using to call HealthKit on both devices is: let dateRange = HKQuery.predicateForSamples(withStart: Date().removeMonths(numberOfMonths: 1), end: Date().endOfDay()) let predicate: NSPredicate predicate = NSCompoundPredicate(type: .and, subpredicates: [dateRange]) let query = HKStatisticsQuery(quantityType: HKQuantityType(.stepCount), quantitySamplePredicate: predicate, options: .cumulativeSum) { _, result, error in if error != nil { //print("Error fetching step count, or there is no data: \(error.localizedDescription), \(startDate) -> \(endDate)") onComplete(0) return } if let result, let sum = result.sumQuantity() { let stepCount = sum.doubleValue(for: HKUnit.count()) DispatchQueue.main.async { onComplete(Int(stepCount)) } } } healthStore.execute(query) }

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); } };

Hello, is there a way to present WorkoutPlan preview just like it was presented on WWDC video: https://developer.apple.com/videos/play/wwdc2023/10016/ with WorkoutCompositions? Or was this way ditched completely and is not possible to reproduce anymore? I find it weird that this view modifier accepts non-optional WorkoutPlan when the process of creating one can fail for many reasons with fatalError (that's another issue - why isn't there throws used anywhere?) when not checked with dedicated methods and I think that it would make more sense to create WorkoutPlan when user completes filling some kind of form. Because right now it's needed to compute the non-optional WorkoutPlan for the sake of .workoutPreview modifier live for any changes and that can often lead to errors. Non-modifier way of presenting the preview, like the one presented on WWDC would work really well for my project

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?

Has anyone seen the workout buddy options on watch OS yet? I am not able to get it on my watch. My setup is an iPhone 16 and Watch Ultra 1 with the 26 OS I am currently using beta 3. English US language on both and US as region. I am located in Germany though. I restarted both devices multiple times without any changes. Hopefully someone can help.

Hi guys, We have an app that consumes data from Apple HealthKit. We use an HKObserverQuery to monitor changes in HealthKit data, and occasionally use regular HKSampleQuery requests when the app is in the foreground. Over the past few weeks, we’ve been encountering a significant number of errors when requesting additional HealthKit permissions (beyond what the user has already granted). The error message we’re seeing is: The operation couldn't be completed. (_UIViewServiceInterfaceErrorDomain error 2.) When this error occurs, all previously granted HealthKit permissions are automatically revoked, which is highly disruptive. We have a few questions and would greatly appreciate any insights or explanations regarding this behavior: Could this error occur if a permission request is triggered right as the app moves to the background? Why would previously granted permissions be revoked automatically after this error? If this is due to some internal behavior in iOS (e.g., a system-level protection or timeout), is there any known workaround or best practice to prevent this from happening? Thanks in advance for your help!

Hello. I have implemented background delivery for detecting changes in health kit with HKObserverQuery. It works well, I am reading changes. And I am sending this changes to an https endpoint with using an URLSession.shared.dataTask inside the HKObserverQuery callback while my app is terminated. I have several questions about this: Is starting a URLSession.shared.dataTask inside HKObserverQuery callback when app is terminated is correct way to do it? I am calling HKObserverQuery completion handler whatever dataTask returned success or failure but I am wondering what if the network connection is low and this dataTask response could not received in 2-3 seconds. I have read background deliveries should take 1-2 seconds. Should I use an URL session with background configuration for sending those HTTPS requests? If so, should I use download task or upload task (they don't fit my requirements I am sending a simple json)?
