Health kit - Get shared health data along with my health data - ios

Question

I can able to get my health data list from health kit. I used below code to get my today's step count :
func getTodaysSteps(completion: #escaping (Double) -> Void) {
let stepsQuantityType = HKQuantityType.quantityType(forIdentifier: .stepCount)!
let now = Date()
let startOfDay = Calendar.current.startOfDay(for: now)
let predicate = HKQuery.predicateForSamples(
withStart: startOfDay,
end: now,
options: .strictStartDate
)
let query = HKStatisticsQuery(
quantityType: stepsQuantityType,
quantitySamplePredicate: predicate,
options: .cumulativeSum
) { _, result, _ in
guard let result = result, let sum = result.sumQuantity() else {
completion(0.0)
return
}
completion(sum.doubleValue(for: HKUnit.count()))
}
healthStore.execute(query)
}
But i have one more health data of my brother, where he invited me to see his health data in my real device. Now i was not able to read / get his health data. Is there any way to get that.
Any solution would be great ...!

You don't want a statics query if you want the step count. Try this;
let comp: DateComponents = Calendar.current.dateComponents([.year, .month], from: Date())
let startOfMonth = Calendar.current.date(from: comp)!
searchPredicate = HKQuery.predicateForSamples(withStart: startOfMonth, end: Date(), options: .strictStartDate)
let sampleQuery = HKSampleQuery(sampleType: .stepCount, predicate: searchPredicate, limit: limit, sortDescriptors: [])
{
(query, result, error) in
if error != nil
{
completion(-1)
}
self.hkSampleRecs.removeAll(keepingCapacity: true)
if result != nil
{
for r in result!
{
self.hkSampleRecs.append(r)
}
}
completion(self.hkSampleRecs.count)
}
healthStore.execute(sampleQuery)
Note that I haven't shown you the completion setup I used. I'm also storing the records in an array I defined elsewhere (hkSampleRecs). This example also gives data only for this month so far. Change the dates as you need.
