How to count steps using an Accelerometer?

Question

I have to develop the same functionality as of this Pedometer App

I have observed this Pedometer app in very high detail.

It\'s not a perfect pedometer app.

        var motionManager = CMMotionManager()
        motionManager.deviceMotionUpdateInterval = 0.1
        motionManager.startDeviceMotionUpdatesToQueue(NSOperationQueue.currentQueue(), withHandler:{
            deviceManager, error in

            var accelerationThreshold:Double = 1;
            var userAcceleration:CMAcceleration = deviceManager.userAcceleration;
            if(fabs(userAcceleration.x) > accelerationThreshold) || (fabs(userAcceleration.y) > accelerationThreshold) || (fabs(userAcceleration.z) > accelerationThreshold)
            {
                println("LowPassFilterSignal")
            }
        })
