How do I add my hospital to the list of hospitals available on the Health Records on iPhone application?

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 {         fatalError("*** An error occurred during the initial query: \(errorOrNil!.localizedDescription) ***")       }       if let anchor = newAnchor {         do {           let data = try NSKeyedArchiver.archivedData(withRootObject: anchor as Any, requiringSecureCoding: false)           UserDefaults.standard.set(data, forKey: anchorKey)         } catch {           print("Error retreiving anchor from UserDefaults")         }       }       completion(samples.last, nil)     }           // Setting up long-running query     query.updateHandler = { (query, samplesOrNil, _, newAnchor, errorOrNil) in       guard let samples = samplesOrNil as? [HKQuantitySample] else {         fatalError("*** An error occurred during an update: \(errorOrNil!.localizedDescription) ***")       }       if let anchor = newAnchor {         do {           let data = try NSKeyedArchiver.archivedData(withRootObject: anchor as Any, requiringSecureCoding: false)           UserDefaults.standard.set(data, forKey: anchorKey)         } catch {           print("Error retreiving anchor from UserDefaults")         }       }       if let sample = samples.last {         updateHandler(sample, nil)       }     }     self.healthStore.execute(query)   }

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.

Finally at last Apple Health supports saving .distancePaddleSports, .distanceCrossCountrySkiing, .distanceRowing, .distanceSkatingSports, and much more. The backstory. In the land of 10,000 lakes, there hasn't been a way to save 'canoe' or 'kayak' distance and I've been asking for it for years. Thank you health team for adding it this year! FB7807993 - Add HKQuantityTypeIdentifier.paddleDistance for canoeing, kayaking, etc type workouts (June 2020) Prior we could just save the totalDistance to a workout, but since the HKWorkout initializers were deprecated we no longer have a supported way to save these distances in our workouts. The iOS 18 / watchOS 11 introduction addresses this. If you want to know more why you can't do this in earlier versions you can check these feedback titles: FB10281482 - HealthKit: Deprecation of totalDistance on a workout session of paddleSports breaks apps that used that to save distance to the workout because there is no "paddleDistance" type available to save as sample data (June 2022) FB12402974 - HealthKit: Deprecation of HKWorkout completely breaks support for third party fitness apps from saving non-standard workout distance (June 2023) Great, so there is new support that solves all of these requests and issues for the new version of the OSes. However, the downside is now that there is not much for documentation. Unlike the .runningSpeed and .runningPower introduced in iOS 16 / watchOS 9, none of the new iOS 18 / watchOS 11 types have documentation, at all. To some degree this is understandable, but types from last year still remain undocumented too. Without this information for the data types introduced in both iOS 17/18 and watchOS 10/11 it makes building and integrating with these new types difficult to say the least. We can't make assumptions about anything. Can we get a documentation update for new (and existing) quantity types for when Apple Watch will automatically generate samples? FB14236080 - Developer Documentation / HealthKit: Update documentation for HKLiveWorkoutDataSource typesToCollect for which sample types are automatically collected by watchOS 10 and 11 (July 2024) FB14942555 - HealthKit / Documentation: App Update Release Issue - HKQuantityTypeIdentifiers are missing documentation describing when the system automatically adds data (today) I know that the behavior has changed from release to release for some of these types, so documentation would be based on OS version. If you didn't catch it, watchOS 11 will now associate .cyclingSpeed for cycling workouts both indoor and outdoor. FB12458548 - Fitness: Connected cycling speed sensor did not save samples to health via cycling workout (June 2023 - received reply that only saved for indoor cycling, but not documented otherwise) FB14311218 - HealthKit: Expected outdoor cycling to include .cyclingSpeed quantity type as a default HKLiveWorkoutDataSource type to collect (July 2024) To the other third party fitness apps out there, how are you managing the knowledge of which devices collect which data types on which versions of the OS? Sure, we could look at the HKLiveWorkoutDatSource and inspect the typesToCollect property across a bunch of devices, but again that is trial by error not 'as documented'. Is the behavior of simulators guaranteed to match the behavior of real devices? Maybe, but also maybe not. Fingers crossed for a nice documentation update to spell out all of the behavioral details. Apple folks / DTS, many of the above feedbacks are addressed and I plan to update or close them after the releases this fall. Some are still outstanding. P.S. I hope that .paddleSports gets deprecated and split into individual activity types like skiing did years ago. Their MET scores are different according to the research on the physical activity compendium site. FB7807902 - Split HKWorkoutActivityType.paddleSports into their own activity types (June 2020)

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!?!?!? 😁🤣

In this link, Apple states we can know when a user is in bed vs sleeping and compare their quality of sleep by it. Only, in iOS 18, Apple no longer reports inBed time samples for the Apple Watch. I get why they stopped doing this for the phone, but why the watch? Bug? My app was using the inBed times for this very purpose and now only works for Garmin and Oura who still report inBed times. https://developer.apple.com/documentation/healthkit/hkcategoryvaluesleepanalysis

As the title says, I logged in to iCloud on my simulator on my mac mini m2 and turned on icloud sync. My health data is in iCloud but it wont load in. When I go to documents for example I can see documents that I have loaded so I know something is working right. I have tried clicking Feature -> Trigger iCloud sync with no luck. I have tried logging out and logging back in, no luck. I have tried Restarting the simulator with no luck. The app I am building uses health data and there is no other way to get health data (heart rate, workouts, sleep) in the simulator. Please help, Thank you

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

I am creating a watchOS app with XCode, and am experiencing an issue where workouts do not start on watchOS versions 9.6.3 and later. ・App specifications Start workout when app starts code (swift) workout?.startActivity(with: Date()) ·phenomenon In watchOS version 9.6.3 or later, after the Apple Watch runs out of battery or is turned off. When you turn on your Apple Watch and start using it, even if you start a workout (startActivity),The status may not change to running and the workout may not work. *Workout always worked on watchOS versions earlier than version 9.6.3. *The workout will work if you close the app and start the app again. If anyone has any information, please provide it.

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?

My Apple Watch after the beta update is not syncing the activities sometimes with Apple Health. I just completed a 2.5 km walk, and it showed on Apple Health, yes, but it did not affect my daily goals. This is not the first time this has happened; this is just one of the examples that I'm sharing, other than what has been some problems that I am seeing after the beta update. Additionally, the camera remote app is not working correctly as I cannot see anything on the watch screen like I used to.

In my app the the statisticsUpdateHandler fetches data from the HealthKit when I open the app from sleeping/standby state. This works fine, except when I leave the app running in the foreground and close the phone for an extended period. This triggers the .errorDatabaseInaccessible error. This seems to stop the statisticsUpdateHandler, maybe set it to nil or something similar. What is the proper way to handle the error to keep it running? As shown in the code below I have tried setting the completion data to the current data. But it stills seems to exit, and thus require a complete restart of the app to re-register the update handler. Thanks Tommy Task { do { try await healthStore.requestAuthorization(toShare: [], read:healtTypes) fetchPast14daysData() } catch { print("Error requesting access to health data") } } func fetchDiscreteData(startDate: Date, type: HKQuantityTypeIdentifier, completion: @escaping([WorkoutMetric]) -> Void) { let datatype = HKQuantityType(type) let interval = DateComponents(day: 1) let query = HKStatisticsCollectionQuery(quantityType: datatype, quantitySamplePredicate: nil, options: .discreteAverage, anchorDate: startDate, intervalComponents: interval) query.initialResultsHandler = { query, result, error in ... } query.statisticsUpdateHandler = { query, statistics, result, error in var lock_error_detected: Bool = false // Handle errors here. if let error = error as?

Hi, there seems to be two methods to fetch data from HealthKit and calculate statistics on intervals of the data; HKStatisticsCollectionQuery and HKStatisticsCollectionQueryDescriptor. I am currently using HKStatisticsCollectionQuery, but HKStatisticsCollectionQueryDescriptor seems to do the same, but with very different code setup. Could anyone provide any advice on which method is preferable? Will the older HKStatisticsCollectionQuery become obsolete in the near future? Thanks Tommy

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 everyone, I need to display a Graph based on Screen-time of apps per hour, from 12Am to 11PM. Am able to get the screen-time data for whole day with each app's total screen-time value. Am kind of confused how can I get the per hour screen-time of apps. I have applied filter of day DeviceActivityFilter( segment: .daily( during: Calendar.current.dateInterval( of: .day, for: .now )! ), users: .all, devices: .init([.iPhone, .iPad]) ) Am also using this data to display apps with their usage just like Apple's Screen_time in settings. I need to display exact same graph just like Apple's screen in phone settings for a Day.

Hi guys, In WWDC23 session 10016: Build custom workouts with WorkoutKit , the presenters mentioned that a Workout Plan can be exported to a JSON or binary file, and also showed a code snip: let binaryRepresentation = try myCyclingWorkout.dataRepresentation(in: .compactBinary) However in the current SDK, the property dataRepresentation can not be exported with a specific format, the base64EncodedString() result is unreadable. Does anyone know how to export it as a JSON string now? Thanks very much.

I started with the custom workout example from Apple. I was able to load the apps from my mac (xcode) to my iphone. I can run the apps on my iphone. I completed the authorization and reviewed the workout. I then uploaded the workout to the watch and it appeared to work. It never showed up on the watch. I tried restarting the watch and iPhone. I have. a second watch and I tried that. Nothing helped. IPhone 14 with ios 18.2. Watch is Series 6 with watch OS 11.2. I also tried it with the watch on the charger but no change. Workout Kit seems like a good idea, but not if you cannot get it on your watch. It seems very few people are using it as there is little info online.

I want to get the barometric pressure reading from the built-in barometer to display it in my iOS app. When I use CMAltimeter.startRelativeAltitudeUpdates(), my app receives no relative altitude update events, which means I can't view the barometric pressure from the sensor (because that's only contained in CMAltitudeData, not CMAbsoluteAltitudeData. If I use CMAltimeter.startAbsoluteAltitudeUpdates(), I get absolute altitude update events every second or so. NSMotionUsageDescription is set. I have tried the following things, all of which haven't worked: Only calling startRelativeAltitudeUpdates() and not startAbsoluteAltitudeUpdates() Calling CMSensorRecorder.recordAccelerometer(forDuration: 0.1), as suggested in this thread Calling CMMotionActivityManager.queryActivityStarting(from: .now, to: .now, to: .main), as suggested here Physically moving my iPhone up and down about 200 feet using an elevator; I see absolute altitude updates which are in line with what's expected, but still receive no relative altitude update events Calling the same APIs in a watchOS app on an Apple Watch Series 10; I see much less frequent absolute altitude updates, and still no relative altitude updates I know the barometer sensor is working, because when I move my iPhone up and down even a foot or two indoors, I see an immediate change in the absolute altitude reading that I know wouldn't come from GPS. This example code, when run on my iPhone 16 Pro running iOS 18.1.1, prints updates started and then updating absolute every second, but doesn't print anything else. The absolute altitude, accuracy, and authentication status fields update (and the auth status shows 3, indicating .authorized), but the relative altitude and pressure fields remain as --. struct ContentView: View { @State private var relAlt: String = "--" @State private var relPressure: String = "--" @State private var absAlt: String = "--" @State private var precision: String = "--" @State private var accuracy: String = "--" @State private var status: String = "--" var body: some View { VStack { Text("Altitude: \(relAlt) m") .font(.title3) Text("Pressure: \(relPressure) kPa") .font(.title3) Text("Altitude (absolute): \(absAlt) m") .font(.title3) Text("Precision: \(precision) m") .font(.title3) Text("Accuracy: \(accuracy) m") .font(.title3) Text("Auth status: \(status)") .font(.title3) } .padding() .onAppear { let altimeter = CMAltimeter() startRelativeBarometerUpdates(with: altimeter) startAbsoluteBarometerUpdates(with: altimeter) status = CMAltimeter.authorizationStatus().rawValue.formatted() print("updates started") } } private func startRelativeBarometerUpdates(with altimeter: CMAltimeter) { guard CMAltimeter.isRelativeAltitudeAvailable() else { relAlt = "nope" relPressure = "nope" return } altimeter.startRelativeAltitudeUpdates(to: .main) { data, error in if let error = error { print("Error: \(error.localizedDescription)") return } if let data = data { print("updating relative") relAlt = String(format: "%.2f", data.relativeAltitude.doubleValue) relPressure = String(format: "%.2f", data.pressure.doubleValue) } else { print("no data relative") } } } private func startAbsoluteBarometerUpdates(with altimeter: CMAltimeter) { guard CMAltimeter.isAbsoluteAltitudeAvailable() else { absAlt = "nope" print("no absolute available") return } let altimeter = CMAltimeter() altimeter.startAbsoluteAltitudeUpdates(to: .main) { data, error in if let error = error { print("Error: \(error.localizedDescription)") return } if let data = data { print("updating absolute") absAlt = String(format: "%.2f", data.altitude) precision = String(format: "%.2f", data.precision) accuracy = String(format: "%.2f", data.accuracy) } } } } Is this behavior expected? How can I trigger delivery of relative altitude updates to my app?
