HKWorkoutEvent

Could you add pause and resume function in your app using the HKWorkoutEvent?

Compile Error with Xcode Version 7.0 beta 4 (7A165t) and watchDevice with OS 2

WatchKit App Extension/InterfaceController.swift:25:18: error: use of unresolved identifier 'HKQueryAnchor'
var anchor = HKQueryAnchor(fromValue: Int(HKAnchoredObjectQueryNoAnchor))

WatchKit App Extension/InterfaceController.swift:105:96: error: 'InterfaceController' does not have a member named 'anchor'

Session not stopping on device

the session is not ending when stopped, heart rate is still updating

App no longer builds with WatchOS 2 Beta 4

I have been unable to fix a compiler error when building the app. This occurs with Watch OS 2 beta 4 and xcode 7 beta 4

Works with IOS 11?

Hello

Do you know how this work in IOS 11?

HealthKit Authentication not returning to watch.

I'm starting the workout session in the willActivate method. After allowing the read permissions in the parent app, the label is not showing bpm. Any solution to this? thanks in advance.

What's the deal with 'HealthKit.framework'?

Hi!

Thanks for your exemple! This is only a question and not really a problem with your source code.

One of the steps necessary to build the solution, according to the readme, is to 'Setup HealthKit for the WatchKit extension target.'.

Well, I've tried to do that, but it is as if my XCode instalation doesn't have a 'HealthKit.framework'. I even tried to manually find the file or start from the scratch from a new project, but on all the cases, Xcode doesn't find the framework.

I even posted a question on StackOverflow (http://stackoverflow.com/questions/31734838/not-able-to-turn-on-healthkit-capability).

If you know what's going on, I'd really appreciate the help!

Xcode 7 beta 5 build error: Expression does not conform to type 'NilLiteralConvertible'

Hey, thanks for the great work (with this repo)!

I'm getting a build error on https://github.com/coolioxlr/watchOS-2-heartrate/blob/master/VimoHeartRate%20WatchKit%20App%20Extension/InterfaceController.swift#L110

watchOS-2-heartrate/VimoHeartRate WatchKit App Extension/InterfaceController.swift:110:83: Expression does not conform to type 'NilLiteralConvertible'

Using Version 7.0 beta 5 (7A176x)

This error doesn't make sense (on Xcode & Apple's part) since their documentation says that passing in nil is valid

App Throws an Exception

App throws an exception at the following line let value = sample!.quantity.doubleValueForUnit(self.heartRateUnit) but I haven't been able to figure out why

app crashes when I tap "Start"

hey all, just notified that the app crashes once I've given authorization and tapped "Start". Anyone seeing this too?

Heart rate stops checking when screen asleep

Perhaps a limitation of OS, but do you know of any workaround for this problem? Thanks

(Also is there a way to speed up how often it checks the heart rate?)
