Retrieve HKWorkoutTypeIdentifier from a HealthKit query

Question

In a HealthKit query, is there a way to retrieve the original HKWorkoutTypeIdentifier used to store the data?

I know you can use HKWorkoutTypeIdentifier to query for specific workout types; but, that's not what I'm trying to do. The question I want to answer, is "What types of workouts has the user done?"

The Apple Health app has a list, as do some third-party apps. But I can't figure out how they're doing this.

Any ideas?

Answer 1

Once you've got the samples returned from the query, you can use .workoutActivityType on each workout sample to access the HKWorkoutActivityType that's set for that sample.

Answer 2

Just as Belle said, you can use.workoutActivityType on a sample. However that only returns the HKWorkoutActivityType, which is a Uinit. If you want to display it as a string, for example "running" you need to use the extension mentioned here .

Then you can use.name to return a string with the activity type. So if you have a sample called workout:

let activityType = workout.workoutActivityType.name
