NSHipster has a good article to talk about the core motion: http://nshipster.com/cmdevicemotion/

A better way to regularly update UI with motion data is to use the patter as shown in below:

if manager.accelerometerAvailable {
     manager.accelerometerUpdateInterval = 0.1
     manager.startAccelerometerUpdatesToQueue(NSOperationQueue.mainQueue()) {
     [weak self] (data: CMAccelerometerData!, error: NSError!) in
          accelX.text = String(format: "%.2f", data.acceleration.x)
     }
}
