I'm trying to achieve a specific UI design in SwiftUI where the bottom section of my List has a different background color than the top section. For example in the Medications portion of the Health app, the "Your Medications" Section has a different background than the top "Log" Section. How do I achieve this?: Here some example code. I wonder if I am supposed to use two Lists instead. If I use two Lists though and nest it in a ScrollView, the height of the lists needs to be specified. I am working with dynamic content, though so I don't think that is ideal. class ProtocolMedication {} // Example model struct HomeView: View { @Query private var protocolMedications: [ProtocolMedication] var body: some View { NavigationStack { List { // Upper sections with default background Section { Text("Content 1") } header: { Text("Log") } // Bottom section that needs different background Section { ForEach(protocolMedications) { medication in Text(medication.name) } } header: { Text("Your Medications") } } .listStyle(.insetGrouped) } } }

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

We currently use the HKCategoryValueMenstrualFlow enum to determine the type of menstrual flow: light, medium, etc. a user is having. We also use this enum in determining if it's an actual period day. The Problem I see HKCategoryValueMenstrualFlow was recently deprecated but has not been replaced by another data type. Are there plans to replace/update it with another data type? When or at what point in the future will this deprecation cause a problem in my code?

I am building a watchOS app with iOS companion app. The watch app needs to track the heart rate during the night or while user is sleeping. And the desired frequency of measurement is 0.2Hz (every 5 seconds) For this I am using the HKWorkout mode with mindAndBody session. While it works fine, One of the main issue is: after about 6-7 hours of usage, the battery on the watch drains between 40% (Series 9) and 100% (series 7, I think) My questions: Are there any other option to track user's heart rate without workout, while the app could be in background? Another side effect of this workout mode is, Even if we choose not to save the workout in HealthKit, the Activity rings gets populated by this mindAndBody session, which makes it when the user is waking up, the bar is already full, This is not desired. Is there any option to specify for ActivityRing skips this? Highly appreciate any help in advance. Cheers - Prakash

As a user, there are times when I don't wear my sleep tracker to bed, but I nonetheless want to record my sleep times. Apple Health supports this with the "Add Data" feature, but it's not possible to provide a time zone in the form. Then as a developer, user-added sleep samples are missing time zone information. I would expect that the time zone is requested within the Add Data form. Without this information provided at input time, downstream applications are forced to infer the time zone ourselves, leading to potentially buggy or unintuitive behavior.

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 encountering an issue with HealthKit permissions and would appreciate some guidance: In my app's previous version, I granted write permissions for HKObjectType.workoutType() via the WatchKitExtension. Now, in the upcoming version, I'm trying to request read permissions for both HKObjectType.workoutType() and HKSeriesType.workoutRoute() via the iOS app. However, after granting access: The read permissions for Workout and Workout Route don't show up under Settings -> Health -> Data and Access -> [My App]. The Workout Route permission status remains notDetermined, even though I selected "Allow" when prompted. Interestingly, if I request the same permissions via the WatchKitExtension, everything works as expected, and the issue doesn't occur. Has anyone experienced a similar issue or have insights into why this might be happening? Could it be related to requesting permissions from the iOS app instead of the WatchKitExtension?

I'm working on an app that reads and writes exercise minutes to HealthKit. Everything functions correctly up to iOS 18.0.1, but starting from iOS 18.1, my implementation is no longer working as expected. Here's the code snippet I use to write to HealthKit: let workout = HKWorkout(activityType: .other, start: startDate, end: endDate) try await healthStore.save(workout) This code successfully writes to both workouts and exercise minutes in iOS 18.0.1 and earlier. However, from iOS 18.1, it only writes to workouts and not to the exercise minutes data source. Has anyone encountered this issue or have insights on how to resolve this?

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

State of Mind is an amazing feature, and I want to provide a similar experience to the Journal app, making it easy to record emotions. Can you consider public State of Mind record UI api.

Hi, My app reports daily step counts, and I’m trying to use HKCumulativeQuantitySample to report them to HealthKit by adding such objects with each update: let sample = HKCumulativeQuantitySample(type: .stepCount, quantity: HKQuantity(unit: HKUnit.count(), doubleValue: dailyTotal), start: startOfDay, end: nowDate) However, HealthKit interprets them as regular samples—it sums them into a global aggregate instead of updating the daily cumulative value. So if I report the daily step count as 500 and then 550, HealthKit interprets it as 1,050 steps instead of 550. Is this expected behavior? If so, what is HKCumulativeQuantitySample intended for, and how should it be used? I’m struggling to find any examples. Thank you

I'm currently trying to collect some of the following data whilst running a workout in a WatchOS app I'm building. Below are the data points I'm trying to retrieve: HKQuantityType.init(.heartRate) HKQuantityType.init(.oxygenSaturation) HKQuantityType.init(.respiratoryRate) HKQuantityType.init(.bloodPressureSystolic) HKQuantityType.init(.bloodPressureDiastolic) HKQuantityType.init(.heartRateVariabilitySDNN) I'm using the following delegate function workoutBuilder(_:didCollectDataOf:) which is part of HKLiveWorkoutBuilderDelegate Something I'm realising whilst running this on the simulator and on my Apple Watch is out of all of the Quantity types I'm requesting. Only the heart rate is being called via the delegate function when trying to retrieve the statistic. Is this the intended behaviour of this API? Since there's no docs about what is and isn't exposed

I´m working within the health felid with a few apps. Accordingly to science one of the most important parts to keep healthy is every day walking. But it is not to walk slow. You need to come to a little speed (not running or even jogging). But to rais your puls. This is when you get the "real health effect". In general it is around 6km/h. It would be great if apple could make this info available for us developers. I think lots of developers will be happa and use this to make better apps and get more people in a healtheyer life. Looking forward to get some feedback on this. Thank you! Cheers Peter

Hello everyone, I hope you’re all doing well. I’m not a developer, but I have an idea for an iOS app that I’d love to get your thoughts on.

Hi everyone, I am trying to send a request to my server in my watch application when HKObserverQuery is triggered. This is working fine when my app is in foreground however the request is not sending when the app manually terminated or in background. HKObserverQuery works fine and triggered in these cases however the request is not sending. I researched about URLSessionConfiguration.background and background sessions but I could not figure it out. I don't want to download or upload a file, I just want to send a simple request when HKObserverQuery is triggered. Can you show me to a path way to make it possible? I am trying to test my watch app with my iPhone, I am assuming the behavior of these scenarios might be same in both device, am I correct? let urlsession = URLSession(configuration: URLSessionConfiguration.background(withIdentifier: "enablement"), delegate: self, delegateQueue: nil) let dataTask = urlsession.dataTask(with: urlRequest) dataTask.resume() As shown in the code snippet, I tried to set background configuration to my URLSession. I enabled background fetch in background modes. Apple documentation says, dataTask can not run in background -> https://developer.apple.com/documentation/foundation/urlsessiontask However I don't want to perform a long running task such as downloading or uploading.

I am encountering a problem with HealthKit authorization in my app. In a previous version of the app, write permission for HKWorkoutType was already granted. In the new version of the app, I added a request for read permissions for both HKWorkoutType and HKWorkoutRoute. After updating the app, the following occurs: I can successfully fetch workout data using HKSampleQuery, and authorizationStatus(for: HKObjectType.workoutType()) returns .sharingAuthorized, indicating that the app has access to the data. However, when I check the Health app (Settings -> Health -> Data Access & Devices -> [App Name]), the read permission does not appear in the list. The write permission is still visible, but the newly requested read permission is missing. This behavior is unexpected because, despite being able to access the data programmatically, the read permission is not listed in the Health app settings. I have already verified that I am requesting the read permissions correctly in the code using requestAuthorization for both HKObjectType.workoutType() and HKObjectType.seriesType(forIdentifier: .workoutRoute). I would appreciate guidance on why this issue is occurring and how to ensure that read permissions are displayed correctly in the Health app settings.

I've realised with the sample code from the WWDC video below I'm getting the following error when trying to use the iPhone simulator and apple watch simulator paired. Whenever i try to test out the sample project I'm getting the following error. Failed to send data: Error Domain=com.apple.healthkit Code=300 "Remote device is unreachable" UserInfo={NSLocalizedDescription=Remote device is unreachable, NSUnderlyingError=0x600000c9c900 {Error Domain=RPErrorDomain Code=-6727 "kNotFoundErr ('rapport:rdid:PairedCompanion' not found)" UserInfo={cuErrorDesc=kNotFoundErr ('rapport:rdid:PairedCompanion' not found), cuErrorMsg='rapport:rdid:PairedCompanion' not found, NSLocalizedDescription=kNotFoundErr ('rapport:rdid:PairedCompanion' not found)}}} Is it not possible to not test out the new WorkoutKit mirroring API's using the simulator? Currently right now if you run the project you'll notice that you can start a workout session on the iPhone > Apple Watch but there is no way to control and mirror on both devices at the moment i.e You can't control the iPhone app on the Apple Watch and vice versa. Also because of this the iPhone can't send data to the Apple Watch i.e. pause, end, water etc. I'm guessing this is meant to be possible since it seems a bit strange to only be able to test this out with actual devices.
