I checked below link Healthkit background delivery when app is not running
and follow all instruction to get update from my walk count in background mode and if it detect step, send information to my personal server. but it never send to my server even if I walk many hours .
my iOS version is 15.5 and watch os version is 8.6 which is newest version for all
on swiftUI we don't have a--delegate so, I wrote enableDelivery and HKObserverQuery function in main view
I wrote code based on apple's sample code for coffee tracker
import SwiftUI
import HealthKit
import os
import CoreData
// The Coffee Tracker app's main view.
struct CoffeeTrackerView: View {
@EnvironmentObject var coffeeData: CoffeeData
@State var showDrinkList = false
private var backgroundObserver: HKObserverQuery? = nil
private let store = HKHealthStore()
// Properties that determine whether the store is available and ready to use.
private let isAvailable = HKHealthStore.isHealthDataAvailable()
private var isAuthorized = false
// Lay out the view's body.
var body: some View {
// Use a timeline view to update the caffeine dose every minute.
// This works both when the user's interacting with the app,
// and when it's in Always On mode.
TimelineView(.everyMinute) { context in
VStack {
// Display the current amount of caffeine in the user's body.
Text(coffeeData.mgCaffeineString(atDate: context.date) + " mg")
.font(.body)
.fontWeight(.bold)
.foregroundColor(colorForCaffeineDose(atDate: context.date))
Text("Current Caffeine Dose")
.font(.footnote)
Divider()
// Display how much the user has drunk today,
// using the equivalent number of 8 oz. cups of coffee.
Text(coffeeData.totalCupsTodayString + " cups")
.font(.body)
.fontWeight(.bold)
.foregroundColor(colorForDailyDrinkCount())
Text("Equivalent Drinks Today")
.font(.footnote)
Spacer()
// Display a button that lets the user record new drinks.
Button(action: { self.showDrinkList.toggle() }) {
Image("add-coffee")
.renderingMode(.template)
}
}.onAppear{
let steps: HKObjectType = HKObjectType.quantityType(forIdentifier: .stepCount)!
if store.authorizationStatus(for: steps) != HKAuthorizationStatus.notDetermined {
store.enableBackgroundDelivery(for: steps, frequency: .immediate, withCompletion: { (worked, error) in
//registers for background data
let myUrl = URL(string:"https://my_server/testpage?q=processUpdate22")
var request = URLRequest(url: myUrl!)
request.httpMethod="GET"
let task = URLSession.shared.dataTask(with: request){
(data:Data?,response:URLResponse?,error:Error?) in
if error != nil {
print("error \(error)")
return
}else{
print("no error")
}
}
task.resume()
if error != nil {
print(error)
}
})
let sampleType = HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.stepCount)!
let query = HKObserverQuery(sampleType: sampleType, predicate: nil) {
query, completionHandler, error in
let myUrl = URL(string:"https://my_server/testpage?q=processUpdatee")
var request = URLRequest(url: myUrl!)
request.httpMethod="GET"
let task = URLSession.shared.dataTask(with: request){
(data:Data?,response:URLResponse?,error:Error?) in
if error != nil {
print("error \(error)")
return
}
}
task.resume()
if error != nil {
print(error)
abort()
}
// Take whatever steps are necessary to update your app's data and UI
// This may involve executing other queries
// self.getSteps(completion: { (stepCount) in
// print("Step count was updated to \(stepCount)")
// })
completionHandler()
}
store.execute(query)
}
}
}
.sheet(isPresented: $showDrinkList) {
DrinkListView().environmentObject(self.coffeeData)
}
}
