I have just decided I want to make a watch app and am trying to familiarize myself with Xcode and Swift. So I decided to follow the Workout app for watchOs tutorial and the tutorial used this block of code. Text(      Measurement(       value: 47,       unit: UnitEnergy.kilocalories      ).formatted(        .measurement(         width: .abbreviated,         usage: .workout,         numberFormat: .numeric(          precision: .fractionLength(0)         )        )       )     ) However when I try to use this code I get the following error. Value of type 'Measurement<UnitEnergy>' has no member 'formatted' Im using XCode Version 12.5.1 Any help is appreciated!

Hi all, Have anyone ran into the need to read/modify the iOS built-in Bedtimes setup? Could you point me to the documentation about how to read the Sleep or Wakeup alarm setting in Bedtime? Thank you, Will

Hello all, this could surely be a newbie mistake but I'm unable to adopt this protocol to my class object I've created in a new project. The Error: "Cannot find type 'OCKSurveyTaskViewControllerDelegate' in scope" import CareKit import CareKitUI import CareKitStore import ResearchKit import UIKit import os.log final class CareFeedViewController: OCKDailyPageViewController, OCKTaskSurveyViewControllerDelegate { } However, I've been able to locate the 'OCKSurveyViewController.swift" file in the CareKit framework from SPM which has the protocol defined there, but I'm still unable to utilize it. Was the protocol only for demonstration purposes and not for use outside of the WWDC21 - CareKit Code Along?

I'm a researcher working for children with special needs such as ADHD. With my research group, we would like to use the Apple Smartwatch as a monitoring device in several health-related research projects. However, before buying a lot of devices, I need clear and detailed information about the accessibility of SpO2, EDA, ECG, and temperature raw data through the Apple watch. Will I be able to access raw data to embed in my customised app? If I need to develop an app that reads and processes through custom algorithms raw data coming from these sensors, is it possible? I just want clear and detailed information before buying a lot of devices.

Hello everyone, I'm making an app that saves rowing workouts. Rowing workouts are traditionally in meters. I want my workout summaries to always show in meters. I have created and saved a HKWorkout instance. For the totalDistance, I am saving a quantity that uses HKUnit.meter() as its unit. Any intervals that I've associated with the workout are also saved with HKUnit.meter() as the unit. When I look at the Workout in the Health app, it shows the total distance in miles. All the intervals are in miles as well Is there a special piece of metadata that I need to add to my workout to hint to the Health app that I'd like to always see the summary using meters? How can I get my workout to always be shown in meters in the health app? Thank you for your advice, _ michael

Hi, I coded  HKObserverQuery multi time for observing ecg, high heart rate event..etc but App observe one query. Can I set multi HKObserverQuery?

I know that heart rate is sent by HealthKit every 4 seconds. But what about other vital signs? Oxygen saturation, blood pressure, Glucose, respiratory rate and body temperature?

I am new to Swift development. I am building my first WatchOS app that collects motion data. I am collecting motion data using startDeviceMotionUpdates with handler. However stopDeviceMotionUpdates doesn't stop the updates and handler goes in endless loop. class WatchMotionManager: ObservableObject {     let motion = CMMotionManager()     let queue = OperationQueue()     func startQueuedUpdates() {         motion.deviceMotionUpdateInterval = 1.0 / 50.0         motion.showsDeviceMovementDisplay = true         motion.startDeviceMotionUpdates(to: self.queue, withHandler: { (data, error) in                 if let motionData = data {                     //get data                  }         })     }          func stopQueuedUpdates() {     self.motion.stopDeviceMotionUpdates()     } }```

I recently renewed a provisioning profile and now i'm getting the following warning (and failure when building during code signing): warning: Provisioning profile "[redacted]" for "OneMedly" contains entitlements that aren't in the entitlements file: com.apple.developer.healthkit.background-delivery. To use these entitlements, add them to your entitlements file. Otherwise, remove unused entitlements from your provisioning profile. (in target 'OneMedly' from project 'OneMedly') The app does use HealthKit and the provisioning profile (which apple generates) has HealthKit and if I inspect the provisioning profile, it does indeed contain this healthkit.background-delivery attribute. This doesn't seem to be problem for debug builds, only for release builds. Does anyone know what is causing this warning/error? Is there a workaround?

Problem: SwiftUI render wrong size on old device like Apple Watch Series 4. The height was be cut, not well render as series 6 or simulator. Check the screenshots. BTW: But it works well both on watch series 6 real device or simulator. Reproduce： Download “Build a Workout App for Apple Watch”, run the code on a real device of watch series 4 https://developer.apple.com/videos/play/wwdc2021/10009/ On Watch4-44 mm (first line be clip) On Simulator or watch 6.

Hello Team, We are Testing Health Records feature into our Patient Application. We have imported sample data available in Simulator and modelling it using FHIR Model. We are trying to group test results based on Origin(Lab Name and Result Date) of Lab Reports. But we are not able to retrieve Lab Name and Lab Test Panel Mapping information.

Hi Can someone help me find a tutorial of how to access user data in a research kit app or set up a server to collect and manage data?

Hello everyone, I am in the process of building an app that gives the user more statistical information about their sleep, and I would like to access the sleep duration goal and the sleep schedule that the user can set in the Health app. Is it possible to access this information and if so, how do I do that? You are welcome to point me to the specific documentation, I just can't find anything about this in the documentation. Have a nice day, Simon

Can you add sauna to the fitness activities?

Hello, The new iOS 15 'Verifiable Health Records' sample code has an issue when I tap on the 'Request Samples' button: The call to HKVerifiableClinicalRecordQuery in ContentView.swift:63 comes back with an error: "Missing required entitlement identifier: verifiable-health-records" But it's unclear to me where I need to add this entitlement? In the Target , the HealthKit Capability is added with 'Clinical Health Records' selected. Is that not enough? I also added "Privacy - Health Records Usage Description" in the Info.plist, but that didn't resolve it. Thanks, Eiman

Hi, I'd like to create a gym app for apple watch. Is there any way to record the movements of the arms, so that apple watch knows when the movement has been made? Thanks Alberto

If I use the Apple training app for indoor swim workouts, I can see the distance by each swimming stroke style later in the Fitness app. However, if I build my own swim app, the distance by stroke style is not listed. What do I have to add, to have it listed there? The information are saved correct in the HKWorkoutEvent array in the workout.

Hello, i set up a watchOS app. I calculated the active burned energy by myself and add it every second as sample to the running workout builder. When I setup the statistics it sum up the app related burned energy for three times. Then the watchOS send active energy with 0. The samples are stored in the workout session but the total energy is 0. In the documentation apple wrote that if you use other you have to tell the system that the samples have to sum up. How I can do that?

Hello, I bought a new iphone (13) and after the change I can see all my old activity, trends ect. but I don’t have any awards now. I lost all of them. How can I get them again?

When using the code below, I can see both a workout and a workout route within the Apple Health app on simulator, however the two are not connected. On my iPhone 12 mini, I notice similar with workout data from the Strava app. whereas a workout recorded with the Apple Watch Fitness app, will have a workout with a related route. // Save workout to Health store builder.finishWorkout { theWorkout, error in     // Finish route     routeBuilder.finishRoute(with: theWorkout!, metadata: [:]) { workoutRoute, error in     } } Anyone else have this issue?
