Missing Classes in XCode/Swift

Question

In a Swift project I have the line

import HealthKit

Command Click opens a list of imports.

Command Click on any of these classes opens more.

Except: Command Click on

import HealthKit.HKWorkoutSession

opens an empty file.

This corresponds to compiler error messages HKWorkoutSession is unavailable and HKWorkoutSessionLocationType is unavailable in my code.

This started in XCode 7 beta 3 after using it a while. Moving to XCode 7 beta 4 didn't change anything. Cleaning the project doesn't change anything.

I suspect this has nothing to do with HealthKit but with some missing files. So any idea how I can reinstall the HealthKit development files when installing a new XCode don't help? Or any other fix?

Edit:

Answer 1

The HKWorkoutSession is available only in watchOS. Make sure you using in in the watchOS target.

Here is HKWorkoutSession documentation. Check the availability label when using it.
