I've ran into an error with the insertRouteData function of the HKWorkoutRouteBuilder that I can't seem to find any information on. The error is "Unable to find location series 1A193D3B-AFF5-41D8-A967-B1BE08D9F543 during data insert.". It seems to only happen when trying to insert very long routes, in the most recent case it was a 5 hour bike ride with 5900 samples. I save all the route data in a sqlite table as backup and after checking out the data there isn't any red flags as to why it would not insert correctly. Has anyone seen this before and could offer some insight or point me in the right direction to find the source of the error?
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? [HKQuantitySample] else {

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.
I'm trying to hook into the new workoutEffort score supported in iOS 18, I am collecting this information from users when they submit their workout and trying to add a sample to the HKWorkout in the same manner as I've been adding other samples like bodyweight, calories burned, etc.
I'm receiving the error:
HKWorkout: Sample of type HKQuantityTypeIdentifierWorkoutEffortScore must be related to a workout
I tried adding the samples using HKWorkoutBuilder.add([samples]) as which has been working perfectly for calories burned & bodyweight, but I am receiving the above error for workoutEffortScore
As a second approach, I tried adding the sample after I called finishWorkout on the HKWorkoutBuilder and received back the HKWorkout object using HKHealthStore.add([samples], to: HKWorkout) and am still receiving the same error!
I don't know otherwise how to relate a sample to a workout, I thought those were the APIs to do so? I'm using Xcode 16.0 RC (16A242) and testing on an iOS 16 Pro simulator
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!?!?!? 😁🤣
WorkoutKit WorkoutScheduler seems broken with the first beta of iOS 18.2.
I have tested using my app from Xcode and the one that is on the App Store (and working properly on other devices), and it's not working with this new beta of iOS.
They appears in WorkoutScheduler.shared.scheduledWorkouts, but not on the watch.
I even tried with other apps that do the same with
Manual add to Apple Watch with SwiftUI workoutPreview work.
Xcode 16.0
iOS 18.2 Beta 1
WatchOS 11.1
We are seeing an issue where sending data using the asynchronous method HKWorkoutSession.sendToRemoteWorkoutSession(data: Data) will never return in some cases (no success nor failure).
This issue is happening for roughly 5% of Workouts started and will stay broken for the whole workout. The other 95% of the workouts, the connection works flawlessly. This happens on both watchOS 10 and 11, and with phones running iOS 17 or 18. The issue is quite random and not reproducible.
Our app has thousands of workouts a day that use the workout session workout data send, with constant messages being send every few seconds.
In some of those 5% cases the "sendToRemoteWorkoutSession" will throw way later, like 30+ minutes later, if the watch app is awake long enough to capture a log of a failure.
Our code uses the same flow as in the sample project:
https://developer.apple.com/documentation/healthkit/workouts_and_activity_rings/building_a_multidevice_workout_app
Here is some sample code, which is pretty simple.
Setup code:
let workoutSession = try HKWorkoutSession(healthStore: healthStore, configuration: configuration)
workoutSession.delegate = self
activeWorkoutSession?.startMirroringToCompanionDevice { success, error in
print("Mirroring started on companion device: \(success), error: \(error)")
}
workoutSession?.prepare()
then later we send data using the workout session:
do {
print("Will send data")
try await workoutSession.sendToRemoteWorkoutSession(data: data)
print("Successfully sent data") // This nor the error may be called after waiting extensive amounts of time
} catch {
print("Failed to send data, error: \(error)") // This nor the success may be called after waiting extensive amounts of time
}
So far, the only fix is to restart the phone and watch at the same time, which is not a great user experience.
Is anyone else seeing this issue? or know how to fix this issue?

When we upload workout data to HealthKit the route information with the workout detailed data is incomplete: just a few dots.
When we select "Show all workout routes" the route data for the same workout shows correctly.
We use the HKWorkoutBuilder to store the workout data, and add the location data with the HKWorkoutRouteBuilder to the workout with
Is this an Apple Health issue, or do we have to change something in the way we store the location data to the workout?

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?
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)
}
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?
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?

Hi, I have an iPhone/watch app that measures walking/running distance. It starts a workout session records data successfully into healthkit and then ends the workout session. I can see the data in the Health app from my app and it all appears to be correct. The issue I'm having is that the Health app doesn't use my app's data in its total distance for the day. For example, I can add 1 mile of fake data (I know that's not allowed per policy) for testing and it gets successfully added but not used in the total. The health app is only using distances collected by the watch and the phone for calculating the total distance for the day and is ignoring the distance provided by my app. What could I be missing?

Dear Apple Developer Support,
I am writing to request assistance with an ongoing issue I'm encountering while developing an iOS application that utilizes HealthKit to fetch heart rate data.
My goal is to display near real-time heart rate updates continuously same as displaying in the Apple Watch , I want to show in the iPhone Mobile Application for fitness related. I have implemented the following approaches:
HKSampleQuery with a Timer: I've set up a timer to periodically fetch the latest heart rate data.
Despite these efforts, I'm consistently facing the following problems:
Delayed Updates: The heart rate data displayed in the app often doesn't reflect the current heart rate being measured by the Apple Watch. There seems to be a significant synchronization delay.
Inconsistent Background Updates: Background updates, even with background app refresh enabled, are not reliable. The app often only updates when brought to the foreground or after being killed and relaunched.
Entitlements: The com.apple.developer.healthkit.background-delivery entitlement error is missing.
I have thoroughly reviewed Apple's HealthKit documentation, implemented best practices for HealthKit integration, and verified that all necessary permissions are properly configured.
I understand that HealthKit may not be designed for true real-time data, but the current level of delay and inconsistency is making it difficult to provide a useful user experience.
Could you please provide guidance on whether achieving near real-time heart rate updates continuously in an iOS app using HealthKit is possible? If so, what are the recommended strategies and best practices to overcome these limitations?
I have also tested the application on physical devices with Apple Watch, enabled background app refresh, granted permissions, and referred to HealthKit documentation.
I would appreciate any insights or suggestions you can offer to help resolve this issue.
Thank you for your time and assistance.
Sincerely,
Venu Madhav
Apple Watch automatically tracks sleep data and syncs it to the iPhone, making it available through HealthKit for historical analysis. However, there is no way to retrieve real-time data on whether a user has entered sleep, or whether they are in a specific sleep stage at any given moment.
Is it possible to provide an interface for real-time sleep status monitoring
Platform & Version:
iOS Version: 18.3.1
Development Environment: Xcode 16.2, macOS 14.6.1
Description of the Issue:
We're exploring ways to better integrate Apple Fitness+ workouts into our app. We've noticed that some third-party apps, such as Strava and HealthFit, now display Fitness+ workout details, including the title, trainer, and an image.
I’ve been investigating how this is possible, and the only relevant change I’ve found is that HKMetadataKeyAppleFitnessPlusCatalogIdentifier is now being set for Fitness+ workouts. However, I can’t find any public API or official documentation that explains how to use these identifiers to retrieve the associated workout details.
Question:
Is there an official API available to fetch metadata for Fitness+ workouts using these identifiers? Or are these third-party apps potentially accessing private APIs? If no API exists, is the only option to create a manual mapping of these identifiers—something that seems impractical given the constantly evolving Fitness+ workout catalog?
Any guidance on this would be greatly appreciated. Thanks!
