I have an iOS/wOS app that launched last year. Now I want to add complications to it and use the new way of doing complications with WidgetKit. I have everything in place up to the point where I'm supposed to read the data from Health to display it, where it fails with Missing com.apple.developer.healthkit entitlement. This is the new extension I've added It's embedded in the WatchKit app NOT in the WatchKit Extension and I've added permission to read health data directly in the info.plist for the extension I pull the data from the TimelineProvider protocol method func getTimeline(in context: Context, completion: @escaping (Timeline<Entry>) -> ()) { let currentDate = Date() var entries: [WorkoutEntry] = [] ComplicationHealthManager.loadPreviousWorkouts { workout in let workoutEntry = WorkoutEntry(date: currentDate, workout: workout) entries.append(workoutEntry) let timeline = Timeline(entries: entries, policy: .after(currentDate)) completion(timeline) } } with the help of a small manager class class ComplicationHealthManager: ObservableObject { static func loadPreviousWorkouts(completion: @escaping (HKWorkout?) -> Void) { let healthStore: HKHealthStore = HKHealthStore() let workoutPredicate = HKQuery.predicateForWorkouts(with: .traditionalStrengthTraining) let compound = NSCompoundPredicate(andPredicateWithSubpredicates: [workoutPredicate]) let sortDescriptor = NSSortDescriptor(key: HKSampleSortIdentifierEndDate, ascending: false) let query = HKSampleQuery( sampleType: .workoutType(), predicate: compound, limit: 0, sortDescriptors: [sortDescriptor]) { (query, samples, error) in guard let samples = samples as? [HKWorkout], error == nil else { completion(nil) return } let calendar = Calendar.current let todaysSamples = samples.filter{ calendar.isDateInToday($0.endDate) }.last completion(todaysSamples) } healthStore.execute(query) } } The issue is in the closure for the health query where it returns with no workouts but an error stating Error Domain=com.apple.healthkit Code=4 "Missing com.apple.developer.healthkit entitlement." UserInfo={NSLocalizedDescription=Missing com.apple.developer.healthkit entitlement.} The problem here is I don't understand where and how to add an entitlement for the complication extension or the WatchKit app, as none of them have the option for health. I have a health entitlements set for the iPhone app and the WatchKit Extension.
