Code to request authorization for Clinical Records

HealthRecordAccess.swift

// Make sure you import HealthKit
// Get the HKHealthStore reference. Must be single reference in your app.
let healthStore = HKHealthStore()

// Create required Record Type's equivalent HKClinicalType using clinicalType func of HKObjectType
guard let allergyRecord = HKObjectType.clinicalType(forIdentifier: .allergyRecord),
    let medicationRecord = HKObjectType.clinicalType(forIdentifier: .medicationRecord),
    let conditionRecord = HKObjectType.clinicalType(forIdentifier: .conditionRecord),
    let immunizationRecord = HKObjectType.clinicalType(forIdentifier: .immunizationRecord),
    let labResultRecord = HKObjectType.clinicalType(forIdentifier: .labResultRecord),
    let procedureRecord = HKObjectType.clinicalType(forIdentifier: .procedureRecord),
    let vitalSignRecord = HKObjectType.clinicalType(forIdentifier: .vitalSignRecord) else {
        // Handle errors here. This could in case the OS on device is < 12.0. You can use @available(iOS 12.0, *) to avoid that
        fatalError("*** Unable to create the requested types ***")
}

// Pass the Set of required HKClinicalType to get authorization for read only. As Clinical Records as Read only.
healthStore.requestAuthorization(toShare: nil, read: [allergyRecord, medicationRecord, conditionRecord, conditionRecord, immunizationRecord, labResultRecord, procedureRecord, vitalSignRecord]) { (success, error) in
    guard success else {
        // Handle errors here.
        fatalError("*** An error occurred while requesting authorization: \(error!.localizedDescription) ***")
    }
    
    // Your requested access has been authorized by the user.
