let stagePredicate = HKCategoryValueSleepAnalysis.predicateForSamples(.equalTo,value: .asleepREM)         let queryPredicate = HKSamplePredicate.sample(type: HKCategoryType(.sleepAnalysis), predicate: stagePredicate)         let sleepQuery = HKSampleQueryDescriptor(predicates: [queryPredicate], sortDescriptors: [])         do{             let sleepSample = try await sleepQuery.result(for: store)                          print("sleep sample ")             print(sleepSample) with health app on iOS , it says I did rem sleep for 59 minutes. but all sum of sleep sample time is not 59 but 3.7hours. time is also not accurate. sleepSample log is as below what may be the problem?

it really weird. I can't add device because it is grayed out and can't add more uuid. I checked Continue button but it says as first pic, I can add more 45 iPhone but + button is still grayed out

wow, this drive me crazy. I have plenty of storage left after reboot after remove xcode and re install dont solve this problem. funny thing is that editing as is code is okay. but just add new line cause infinite loading

there's position which is simd3 and there 's anchorEntity. I want to get distance between two. how I did is var distance = distance(position, ( self.modelentity.position(relativeTo:nil) ) var distance = distance(position, ( self.modelentity.position ) but both failed because it seems calculating distance between world origin anchor not distance between position to self.modelentity. how can I calculate distance ?
