Hello, I’m currently developing a fitness app for watchOS that lets a user to manually set a desired heart rate target zone (enter numbers representing the lower and upper boundaries) and start a workout (right now it’s only “Other” type). After that my app monitors user’s heart rate and alerts them when they’re out of zone. When user ends the workout, the info about this workout appears on “Fitness” iOS app, and user can see the workout data like Workout Time, Active and Total Calories, Avg. Heart Rate. Also user can see Heart Rate chart with info how their heart rate was changing during a workout (see the Figure 1). Now to the question. When user clicks “Show More” button above the Heart Rate chart, they can see the same Heart Rate chart and another one, with Post-Workout Heart Rate (see the Figure 2). But there is no “Estimated time in each heart rate zone” as one can see in the workout’s details that were recorded from Apple’s workout (watchOS “Workout” app, for a workout of “Other” type as well). Please see the Figure 3. The question is: is it possible to add “Estimated time in each heart rate zone” to workout recorded via my third-party app so it would look like on the Figure 3 in "Fitness" iOS app, and if it's possible, what steps should I undertake to implement this ? Thanks in advance! I posted the screenshots in the replies to the post, because otherwise I was not able to submit a post ("sensitive language" warning, I suspect it's because of the ids in the attached screenshot's urls)

Hello, I am using the project from https://developer.apple.com/documentation/healthkit/workouts_and_activity_rings/building_a_multidevice_workout_app The workout is starting on the watch and I can see the metrics, but it seems the mirroring with the phone is not working, I am getting this errors [mirroring] <HKWorkoutSession:0x600002c10100 57C340BA-2AA9-4477-9AC8-181698A526A5 running [Primary]>: Failed to send data to remote session with error: Error Domain=com.apple.healthkit Code=300 "Remote device is unreachable" UserInfo={NSLocalizedDescription=Remote device is unreachable, NSUnderlyingError=0x600000c53b70 {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)}}} Does anybody else has this issue?

The WWDC23 session number 10016 is referring to a way to generate .workout files (timecode 09:43) in both binary and JSON format. Unfortunately, the API seems to have changed: CustomWorkoutComposition renamed to CustomWorkout .dataRepresentation disappeared Ideally I would like to generate .workout files directly in JSON format but there is no specifications published and no documentation to generate them. Any idea where I should look?

Hello fellow developers, I've recently developed a workout companion watch app for iOS. However, I'm now have a task of implementing custom workouts for my app. I've come across a video demonstrating how to create and schedule custom workouts for the watch app, which I believe will be incredibly helpful for my project. Video Link: Creating Custom Workouts for iOS Watch App If anyone knows of any additional resources, such as articles or videos, that further explores this topic, I would greatly appreciate it if you could share them with me. Thank you for your assistance! Best regards, Pranit Bhogale

Please reference the Sample Planner app which can be found at the below link. https://developer.apple.com/documentation/WorkoutKit/customizing-workouts-with-workoutkit. In WorkoutStore.swift, all of the values are hard coded. I would like to turn them into variables stored in @EnvironmentObject (WorkoutStoreValue). With the below code, using "singleRunStartDelay" as a trial, I can get that variable passed to the WorkStore struct only when the app is first opened, however, I have not been able to get it changed in realtime. I need help with changing the WorkoutStore struct to have the values updated in realtime. I have tried changing the func from static but that gives an error (Instance member 'createSingleRunWorkout' cannot be used on type 'WorkoutStore'; did you mean to use a value of this type instead?) I'm now learning Xcode/SwiftUI. I have been stuck for about four day trying many different ideas. Thanks // Copyright © 2024 Apple.

Hi experts, I got an Ultra2 a while ago and has been using it on walking / running exercise. Recently I came across to this apple site: debug profile and I'm curious about what I would get during the exercise. So I follow the instruction and install the location services profile. After getting the sysdiagnose report, I try to get location related information from it. And it seems that the log from "locationd" and "gpsd" are what I'm looking for. But when I try to look into the nmea information, I found out the sysdiagnose only provide around 10-15 mins of nmea data. For example, let's say I have a walking exercise from 0900 - 1000, but I can only see nmea data from 0945 - 1000. The data from 0900 to 0945 can't be found in the sysdiagnose. Not sure if's the limitation or any setting I can change to increase the logging period? Thanks.

Hi there, I'm new here, looking for a step-by-step tutorial that will help me to achieve my first step. https://developer.apple.com/documentation/workoutkit/customizing-workouts-with-workoutkit downloaded the WorkoutKit sample file. try to run, and connect to my account and team but get an error to connect a device.

Hi. is it possible to create a Custom Workout with different activity types. I want a Custom Workout where the user first has to run and after do skiing. Its like a little bit like SwimBikeRun but with running and Skiing. How can i do this? Thank you

Hello, it is discussed here https://developer.apple.com/videos/play/wwdc2023/10016/ (12:16) regarding WorkoutComposition, but unfortunately, I cannot find this class or structure in the documentation. Has this concept been removed?

With CustomWorkout, I can assign a name (displayName) to workouts, which also appears in the Workout app. Unfortunately, this parameter is missing for common workouts such as SingleGoalWorkout. Is there a reason for this? I find it inconvenient when the name is missing CustomWorkout init(activity: HKWorkoutActivityType, location: HKWorkoutSessionLocationType, displayName: String?, warmup: WorkoutStep?, blocks: [IntervalBlock], cooldown: WorkoutStep?) SingleGoalWorkout init(activity: HKWorkoutActivityType, location: HKWorkoutSessionLocationType, swimmingLocation: HKWorkoutSwimmingLocationType, goal: WorkoutGoal)

Hi, Is there anyway to share a WorkoutScheduler across an iPhone and watch app? If I create a scheduler on the phone app the watch app can't see it and creates its own. I'm using WorkoutScheduler.shared.scheduledWorkouts but end up with two identical sections at the top of the workout app Thanks

In the wwdc2023-10023 session, we go over how the Apple Watch can be used as a primary workout session manager and the iPhone as the mirrored one. How is it possible to create a workout session on the iPhone and optionally mirror it to the Apple Watch to collect heart rate data? In iOS 17, I still cannot instantiate a HKWorkoutSession, I'm assuming it says it's available because we can have an instance of it as a mirrored copy from the Apple Watch. I find it odd that the iPhone cannot manage the primary session. I hope I'm missing something.

I'm experiencing an issue trying to install the 'mirroringworkoutssample' app from the official Apple documentation on my Apple Watch. When attempting a direct installation from the Apple Watch, I receive an error stating, "Cannot install this app due to an inability to verify its integrity." Has anyone else encountered this problem or can provide any solutions or insights? ** I have a 'Development' type certificate that allows for watchOS(it includes iOS, tvOS ..) development. ** also added WKCompanionAppBundleIdentifier com.example.apple-samplecode.MirroringWorkoutsSample7C76V3X7AB.watchkitapp

I was wondering which of the hkquantitytypeidentifiers I can collect while a workout is running. Essentially which of these types are actually being collected by the sensors on the apple watch rather than being read from manual input. Thanks

Hello, I'm trying to understand what's the difference between: HeartRateZoneAlert: static func heartRate(zone: Int) -> Self PowerZoneAlert : static func power(zone: Int) -> Self And also, why HeartRate alerts support range, but Power doesn't support Range?

I am unable to see the workout composition from preview in the new WorkoutKit framework. This is reproducible on an iPhone running iOS 17.0 running xcode 15.0 beta 2. I downloaded the Sample Planner app that showcases the new WorkoutKit framework capabilities , introduced in the session 10016 of wwdc 23. I can create workout compositions but the preview presentation doesn’t work as expected. It shows a black screen without any info. I attached a screenshot. You can reproduce it on the sample app when showing the PresentPreviewDemo view.

Hi, I have an app that implements the Cycling Power Service 1.1, https://www.bluetooth.com/de/specifications/specs/cycling-power-service-1-1/ As expected, I can select this app as a Health Device in the Bluetooth settings of my Apple Watch. However, when I run the BLE app on the paired iPhone, the Apple Watch does not detect the BLE Service as a Health Device! Is this a bug, or is it designed this way? If so, is there another API where I can send power meter data from iOS to a running Watch Workout?

Dear All, Is there a way to remove a workout? In the tutorial app, it is shown how to schedule workouts. But so far, I haven't seen a way to remove them again, neither from the tutorial app nor from the workouts app on the watch. Many thanks and best regards, Patrick
