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 {

}
}

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 cannot access my corporate invoice. I don't know why I couldn't reach it. How and where can I reach it?

I've searched all the App Intent and AssistantSchemas related documentation and I can't find anything related to workout, do I still need to use SiriKit?
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 have an App in objective-c that is using Health data (walk/run, cycling) to give advice to users . I do not want/need to write any data in the Healtkit.
If i do (with the 3 values in the plist / .info :
self.healthStore requestAuthorizationToShareTypes:nil readTypes:readDataTypes
My request crashes.
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Must request authorization for at least one data type'

I keep seeing a red action item to complete a task in settings. IOS beta keeps indicating that I need to enable sensor & usage data. Everything is enabled. I literally enabled everything to get it to go away, but it is still there. Suggestions?
I implemented this to receive updates for specific data types and keep the latest daily information up to date. However, for some reason, it only works for a while before stopping completely.

This is an ongoing issue that I haven't been able to solve:
I am querying different types of HealthKit data over the past year. While this works fine for HRV, it hangs for some users when I'm trying to get heart rate data.
Here's the relevant query
func initialRead(from startDate: Date) async throws -> [HKSample] {
let endDate = anchorStart
let interval: TimeInterval = .days(7)
var currentStartDate = startDate
var currentEndDate = Date(timeInterval: interval, since: currentStartDate)
var samples: [HKSample] = []
while currentStartDate <= endDate {
let datePredicate = SampleType.datePredicate(start: currentStartDate, end: currentEndDate)
let predicate = NSCompoundPredicate(andPredicateWithSubpredicates: [datePredicate,HKQuery.predicateForObjects(withMetadataKey: HKMetadataKeyHeartRateMotionContext, allowedValues: [HKHeartRateMotionContext.sedentary])])
do {
let result = try await withCheckedThrowingContinuation { continuation in
let completionQuery = HKSampleQuery(sampleType: HKQuantityType.heartRate, predicate: predicate, limit: HKObjectQueryNoLimit, sortDescriptors: [.init(key: HKSampleSortIdentifierStartDate, ascending: true)]) { query, samples, error in
if let samples {
continuation.resume(returning: samples)
} else {
if let error {
continuation.resume(throwing: error)
} else {
continuation.resume(returning: [])
}
}
}
healthStore.execute(completionQuery)
}
samples = samples.merge(from: result)
} catch {
Logger.general.error("Reading failed for dates \(currentStartDate) to \(currentEndDate): \(error)")
}
currentStartDate = currentEndDate
currentEndDate = Date(timeInterval: interval, since: currentStartDate)
}
return samples
}
extension HKSampleType {
static func datePredicate( start:Date?, end:Date?) -> NSPredicate {
HKQuery.predicateForSamples(withStart: start, end:end, options: .strictStartDate)
}
}
For reference, I expect about 1000 sedentary samples per week. Basically what happens for these users is when they start reading the HR data, the app hangs. They start each read manually via a special TestFlight build with buttons for starting the different data type readings.
Any advice on how to proceed with this bug would be great since it only affects some users.
I am able to create test builds for this audience to test different options. One theory is the motion context predicate is screwing something up. If any apple dev can enlighten me how to narrow down the issue, that would be great.
