// Import HealthKit import HealthKit // Create a Health Store let healthStore = HKHealthStore() // Request authorization to access health data func requestAuthorization() { guard let heartRateType = HKObjectType.quantityType(forIdentifier: .heartRate) else { return } let dataTypesToShare: Set = [] let dataTypesToRead: Set = [heartRateType] healthStore.requestAuthorization(toShare: dataTypesToShare, read: dataTypesToRead) { (success, error) in if success { print("Authorization successful") } else { print("Authorization failed with error: \(String(describing: error))") } } } // Read heart rate data func readHeartRateData() { guard let heartRateType = HKObjectType.quantityType(forIdentifier: .heartRate) else { return } let query = HKSampleQuery(sampleType: heartRateType, predicate: nil, limit: HKObjectQueryNoLimit, sortDescriptors: nil) { (query, results, error) in if let results = results as? [HKQuantitySample] { for result in results { let heartRate = result.quantity.doubleValue(for: HKUnit(from: "count/min")) print("Heart Rate: \(heartRate)") } } else { print("Error reading heart rate data: \(String(describing: error))") } } healthStore.execute(query) }
