Swift watchOS 2 - CMSensorDataList

Question

Short: I don\'t know how to extract the CMRecordedAccelerometerData from the CMSensorDataList after getting one from the CMSensorRecorder. Apple isn\'t providing any documen

Answer 1

Marcus's answer in Swift 4:

//First make the extension to use enumerate in the for-in loop
extension CMSensorDataList: Sequence {
    public typealias Iterator = NSFastEnumerationIterator

    public func makeIterator() -> NSFastEnumerationIterator {
        return NSFastEnumerationIterator(self)
    }
}

//Now you can query the recorded data
func printData(){
    let date = Date()
    let recorder = CMSensorRecorder()
      let accelerometerData = recorder.accelerometerData(from: startDate, to: endDate)

     for (index, data) in (accelerometerData?.enumerated())! {
                    print(index, data)
      }
}
