Since I needed some time to figure the implementation out, here is a code example from my workout app "Progression" on how to handle the duration limits:
private func createAndStoreHealthKitWorkout(start: Date, end: Date, workoutName: String) {
let device = HKDevice(name: UIDevice.current.localizedModel,
manufacturer: Constants.deviceManufacturer,
model: UIDevice.current.localizedModel,
hardwareVersion: modelIdentifier(),
firmwareVersion: nil,
softwareVersion: UIDevice.current.systemVersion,
localIdentifier: nil,
udiDeviceIdentifier: nil)
let maximumAllowedWorkoutDuration = 345600.0
let endDate: Date
if #available(iOS 13, *) {
let timeIntervalAdjustedForMinimumLimit = HKObjectType.workoutType().isMinimumDurationRestricted ?
max(
end.timeIntervalSince(start),
HKObjectType.workoutType().minimumAllowedDuration
) : end.timeIntervalSince(start)
let timeIntervalAdjustedForDurationLimits = HKObjectType.workoutType().isMaximumDurationRestricted ?
min(
timeIntervalAdjustedForMinimumLimit,
HKObjectType.workoutType().maximumAllowedDuration
) : timeIntervalAdjustedForMinimumLimit
endDate = Date(timeInterval: timeIntervalAdjustedForDurationLimits, since: start)
} else {
endDate = Date(timeInterval: maximumAllowedWorkoutDuration, since: start)
}
let workoutEntry = HKWorkout(
activityType: .traditionalStrengthTraining,
start: start,
end: endDate,
workoutEvents: nil,
totalEnergyBurned: nil,
totalDistance: nil,
totalSwimmingStrokeCount: nil,
device: device,
metadata: [Constants.workoutNameMetadataKey: workoutName]
)
healthStore?.save(workoutEntry, withCompletion: { (_, _) in })
}
Hope I saved someones time.
Note that the hardcoded "maximumAllowedWorkoutDuration" (probably not needed for <iOS 13 versions) is the limit for workout object types.
