I am running a Healthkit query.
I can get the value but how do I access the uuid??? I want to access "90A68DE6-A0E1-473B-944B-1132F447C57D".
How do I get this???
results:

Code Block ([6 mg/dL 90A68DE6-A0E1-473B-944B-1132F447C57D "Health" (14.2), "iPhone12,1" (14.2)metadata: {    HKWasUserEntered = 1;
} (2021-02-22 09:12:00 +0800 - 2021-02-22 09:12:00 +0800)

Code Block let query = HKSampleQuery(sampleType: glucoseType!, predicate: predicate, limit: 20, sortDescriptors: nil) { (query, results, error) in                for result in results as! [HKQuantitySample] {
                  let bloodGlucose = result.quantity.description    // this gives the value "6mg/dL"
}

Why don't you simply access the property uuid?

Code Block         for result in results as! [HKQuantitySample] {
            let uuid = result.uuid
            print(uuid)
            let bloodGlucose = result.quantity.description
            //...
        }

By the way, what is the type of results? You should better avoid risky forced casting as! as far as you can.
