Thank you. Removing and adding the local packages again also fixed my issue with XCode 14.3.1.

I though that the code above was working (I did a quick test), but after this morning run, the workout saving failed... When this code is executed on a locked iPhone I get the following log: Whereas when saving from an unlocked iPhone I get : It seems that the healthStore.save(hkworkout) method do not really save the workout when the iPhone is locked :-( I will try to manually add the locations to the workout without using the HKWorkoutRouteBuilder... @HealthKit team, any tip on how to save a workout with a route on a locked iPhone ?

I think I finally have found a way to save a workout with a route even when the iPhone is locked. TLDR: We should create the workout ourselves and not use a HKWorkoutBuilder. I use the following code: let healthStore = HKHealthStore() let energyBurned = HKQuantity(unit: HKUnit.kilocalorie(), doubleValue: totalEnergyBurned) let distance = HKQuantity(unit: HKUnit.meter(), doubleValue: workout.distance) let hkworkout = HKWorkout(activityType: .running,                           start: workout.start,                           end: workout.end,                           duration: workout.duration,                           totalEnergyBurned: energyBurned,                           totalDistance: distance,                           metadata: nil) try await healthStore.save(hkworkout) let route = HKWorkoutRouteBuilder(healthStore: healthStore, device: .local()) try await route.insertRouteData(locations) try await route.finishRoute(with: hkworkout, metadata: nil) The tip is to directly create the workout as the HKWorkoutBuilder.finishWorkout() would return nil on a locked iPhone (why?) and then use a HKWorkoutRouteBuilder and call finishRoute() with the created workout. Hope it will help others.
