Hello fellow developers, I'm using Xcode 14, MacOS 13.2, and trying to make an iPhone and Apple Watch companion app using HealthKit. I'm getting the following error: Code=4 "Missing com.apple.developer.healthkit entitlement." UserInfo={NSLocalizedDescription=Missing com.apple.developer.healthkit entitlement.} From this line of code: private var healthStore = HKHealthStore() Since Xcode there is no Info.plist file and I've tried adding it but the build fails if I add a properties file that is called Info.plist. I've seen recent documentation that states to use project -> Info -> Custom iOS Target Properties and values such as: "Privacy - Health Update Usage Description" and add a description greater than 12 characters. However, this property and other properties that I add to this section section disappear when I navigate away from that tab. This is weird because if I try to re-enter that value, I am presented with a dialog that states, "Replace Existing Pair". Again, I can add it and then navigate away and it disappears. Regardless, I can't find any documentation in the Apple developer forums or any other part of the Internet. Is this a bug?

Until the last Apple Watch update I was retrieving sleep data from HealthKit using the .asleep identifier and reliable got sleep and the date the sleep was credited to in Apple Health. Since the update there appears to be no reliable way to make sure that the sleep calculated from the various sleep states get credited to the same day Apple Health credits the sleep to. We have no interest in analyzing sleep states, all we want is total sleep for a given day and that the date for the sleep is the same as Apple Health displays. How can this be reliably achieved?

Does anyone know if the API for medication tracking in Apple Health is available / when it would be available by?

Is it possible to retrieve the sleep schedule wakeup and bedtime times using HealthKit? I can retrieve sleep analysis values, but I don't want the detailed data just the wake up and bedtime times the user has possibly specified in the health app, I can't see any way to retrieve those values. Thanks.

I trying to save the height from apple HealthKit in variables but it is only 0.0 Moreover I get the height in the result handler but I can't save it to the var. Do you have any ideas? greeting Fabian

Hello, i am currently working on an university project about the forensic usage of fitness tracker data. To this point I already extracted the healthdb_secure.sqlite database from an encrypted iPhone Backup. I was able to get all data visualized in the HealthApp. At least I got one problem. The heart rate variability. I can extract the summarized value shown in the health app, but I got big issues to get the beat to beat measurement. I am stuck at this point: The hrv entries can be found in the samples table under the data_type = 139. With a left outer join with associations on samples.data_id = associations.child_id you get the corresponding parent_id. Only for each parent_id there is an entry in the binary_samples table with an associated byte array. I am currently trying to decode this byte array, but it’s very hard to get data from this. so my question is, if anybody knows how to decode this byte array or if somebody know how to get the beat to beat measurement for each heart rate variability entry. best regards

Is it possible to update clinical records, like allergy, vital, medication to HealthKit app. I'm able to read, now I looking to update

I have an app that adds cycling workouts to HealthKit. Here is the snippet of code that does it. let workout = HKWorkout( activityType: HKWorkoutActivityType.cycling, start: startTime, end: endTime, duration: 0, // compute from start and end data totalEnergyBurned: HKQuantity( unit: .largeCalorie(), doubleValue: Double(calories) ), totalDistance: HKQuantity(unit: .mile(), doubleValue: distance), metadata: nil ) try await store.save(workout) This successfully adds a workout and the number of calories is recorded in the Health app. However, the iOS Fitness app and the watchOS Activity app do not recognize the calories so the MOVE ring is not affected. What else do I need to do to let those apps know that my workout burned calories?

I wrote an app that successfully adds a cycling workout to HealthKit. I can see in the Health app that there are new entries under "Workouts", "Active Energy", and "Exercise Minutes" all from me just adding an HKWorkout and a HKQuantitySample. However, there is no new entry for "Cycling Distance". I assumed that since the workout I added includes the fact that the activityType is HKWorkoutActivityType.cycling and I provided the distance, that it would also add an entry for "Cycling Distance". Is there something extra I need to do to get that?

Hi A watchOS app that has the property 'Required Background mode (Watch)' set to 'Workout processing' always stay in the foreground. This is what I want and correct. But, the app stays in the foreground regardless if there is an active HKWorkoutSession or not. During an active HKWorkoutSession this is perfectly fine but before a workout has started of after it has ended the app should not stay in the foreground. The only possibility a user has is to use the app-switcher and kill the app, otherwise it will always come to the foreground. Is there a possibility to set the 'required background mode' at runtime? Or any other possibility to control if the app should stay in foreground or not? many thanks for any help Thomas

This is from the code in the video on Exploring Verifiable Health records. @ the 10:28 mark I get an error saying cannot find predicaetForVerifiableClincalRecords in Scope. import HealthKit import Foundation let healthStore = HKHealthStore() let recordTypes = ["https://smarthealth.cards#immunization"] let endDate = Date() let startDate = Calendar.current.date(byAdding: .day, value: -7, to: endDate) let dateInterval = DateInterval(start: startDate ?? .now, end: endDate) let predicate = predicateForVerifiableClinicalRecords(withRelevantDateWithin: dateInterval) <- error here

I am a undergraduate research student at a university lab. I am looking to find raw data for the anomaly detection of ECG measured by the apple watch. I understand that Healthkit provides a visual graph of the ECG data. However, I am in need of the numerical data for research purposes. Is there a way for me to get to this dataset?

I want to develop an APP for testing vital signs. It can test heart rate, temperature, oxygen, and more at the same time. Does Apple provide any SDKs or APIs for things like heart rate and oxygen outside of Workout? Ask another way, that is, can I write the blood oxygen, temperature, etc. test function on my APP?

I try to get data of the restingHeartRate via HKStatisticsCollectionQuery. The simulator doesnt seems to have any records. I can retrieve active heart rate data, and I collected those via a HKWorkoutSession. I set the authorization: ` let readDataTypes: Set = [ HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.heartRate)!, HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.restingHeartRate)!, HKObjectType.characteristicType(forIdentifier: HKCharacteristicTypeIdentifier.biologicalSex)!, HKObjectType.characteristicType(forIdentifier: HKCharacteristicTypeIdentifier.dateOfBirth)!, HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.stepCount)!, ]` The code will retrieve data if I change .restingHeartRate to .heartRate let calendar = Calendar.current let beatsPerMinuteUnit = HKUnit.count().unitDivided(by: HKUnit.minute()) let restingHeartRateType = HKQuantityType.quantityType(forIdentifier: .restingHeartRate)! let endDate = Date() let startDate = calendar.date(byAdding: .day, value: -14, to: endDate)! let restingPredicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: []) let anchorDate = calendar.date(bySettingHour: 0, minute: 0, second: 0, of: Date())! var interval = DateComponents() interval.day = 1 let restingHRquery = HKStatisticsCollectionQuery(quantityType: restingHeartRateType, quantitySamplePredicate: restingPredicate, options: .discreteAverage, anchorDate: anchorDate, intervalComponents: interval) restingHRquery.initialResultsHandler = { restingQuery, statisticsCollection, error in guard let statsCollection = statisticsCollection else { return} print ("statsCollection init \(statsCollection.statistics().count)") } restingHRquery.statisticsUpdateHandler = { restingQuery, statistics, statisticsCollection, error in guard let statsCollection = statisticsCollection else { return } print ("statsCollection update\(statsCollection.statistics().count)") Any advice on how to retrieve some test data?

Have tried several times to reset fitness data. iPhone 12 i os = 16.5 watch, 9.5 series 4

I would like to use this https://developer.apple.com/documentation/healthkit/hkhealthstore/1614170-splittotalenergy but I saw that it's deprecated. Is there any replacement? Thanks!

Some HKDiscreteQuantitySample types have metadata. Is it possible to write a HKSampleQuery that would return samples that match a specific metadata param? Use case: getting heartRate samples that match a specific HKHeartRateMotionContex case (or its raw value).

Hi, I have tried to observe HealthKit data (workouts) with background delivery, but I am faced with a problem - updates don't come when iPhone is locked by Face ID. Everything works fine with an unlocked device. I didn't find any references in the documentations. Is this the expected behavior? Code: func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool { HealthManager.shared.startObservingWorkouts { /* Don't receive updates */ } return true } } class HealthManager { static let shared: HealthManager = .init() private let hkStore = HKHealthStore() init() { } func startObservingWorkouts(handleUpdates: @escaping ([HKWorkout]) -> Void) { hkStore.getRequestStatusForAuthorization( toShare: [], read: [.workoutType()]) { [weak self] status, _ in guard status == .unnecessary else { return } let prediction = HKQuery.predicateForSamples( withStart: Date().startOfDay, end: Date().endOfDay, options: [.strictStartDate, .strictEndDate] ) let query = HKObserverQuery( sampleType: .workoutType(), predicate: prediction, updateHandler: { [weak self] _, completionHandler, _ in self?.getWorkouts { handleUpdates($0 ?? []) completionHandler() } } ) self?.hkStore.execute(query) self?.hkStore.enableBackgroundDelivery( for: .workoutType(), frequency: .immediate ) { _, error in print(error) } } } private func getWorkouts(handleResult: @escaping ([HKWorkout]?) -> Void) { let prediction = HKQuery.predicateForSamples( withStart: Date().startOfDay, end: Date().endOfDay, options: [.strictStartDate, .strictEndDate] ) let query = HKSampleQuery( sampleType: .workoutType(), predicate: prediction, limit: HKObjectQueryNoLimit, sortDescriptors: nil ) { query, samples, error in if error != nil { return } guard let samples = samples else { fatalError("*** Invalid State: This can only fail if there was an error. ***") } guard let workouts = samples as? [HKWorkout] else { return } handleResult(workouts) } hkStore.execute(query) } } @main struct HealthKitTestApp: App { @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate var body: some Scene { WindowGroup { ContentView() } } }

I am receiving the following crash when trying to query data from health kit. It seems to be complaining about end date being before start date however with the values I am passing in that is not possible. Also I tried to purposefully pass in end dates before start date and I still was not able to reproduce this crash. I have attached my code snippet and the crash logs here.

I am writing an app to retrieve the dive info from HealthStore (specifically HKQuantityTypeIdentifier.underwaterDepth and HKQuantityTypeIdentifier.waterTemperature. To get the data, I am using HKQuantitySeriesSampleQuery to get the discrete dive events or values so that I can export them to dive logs (e.g., Subsurface) or to graph the depth profile and temperature. I am able to fire the HKQuantitySeriesSampleQuery to get the depth and then another query to get the temperature. However, is there a way I can fire one query to get both depth and temperature. I would like to not join the two results if possible. Thanks in advance
