How to reset pedometer to 0 in Swift? I am using CMPedometer()

I want to add a button in my app and reset the pedometer to 0 by pressing it. Now I just finish a common pedometer, my code is below:

@IBOutlet weak var step: UILabel!

    var days:[String] = []
    var stepsTaken:[Int] = []
    let activityManager = CMMotionActivityManager()
    var pedoMeter = CMPedometer()

 override func viewDidLoad() {
        super.viewDidLoad()

        var cal  = Calendar.current
        var comps = cal.dateComponents([.year, .month, .day, .hour, .minute, .second], from: Date())
        comps.hour = 0
        comps.minute = 0
        comps.second = 0
        let timeZone = NSTimeZone.system
        cal.timeZone = timeZone
        let midnight = cal.date(from: comps)!

        if(CMPedometer.isStepCountingAvailable()){


            self.pedoMeter.startUpdates(from: midnight) { (data: CMPedometerData?, error) -> Void in
                DispatchQueue.main.async(execute: { () -> Void in
                    if(error == nil){
                        self.step.text = "\(data!.numberOfSteps)"
                    }
                })
            }
        }    }

You cannot "reset the pedometer". It is a piece of hardware.

What you do is write software. No law says that you have to maintain or display as your count the same number that the pedometer is keeping as its count. Maintain your own separate count as an instance property.
