Cannot invoke 'startAccelerometerUpdatesToQueue' with an argument list of type

I am trying to instantiate CMMotionManager while running the following code: 

motionManager.startAccelerometerUpdatesToQueue(NSOperationQueue.currentQueue(), withHandler: {
  (accelerometerData: CMAccelerometerData!, error: NSError!) in
  // 3
  let acceleration = accelerometerData.acceleration
  // 4
  self.xAcceleration = (CGFloat(acceleration.x) * 0.75) + (self.xAcceleration * 0.25)
})

I receive an error: "cannot invoke 'startAccelerometerUpdatesToQueue' with an argument list of type '(NSOperationQueue?, withHandler: (CMAccelerometerData!, NSError!) -> _)'

What am I doing wrong? Thank you.

I got it working by changing 

NSOperationQueue.currentQueue

to 

NSOperationQueue.mainQueue()
