Here is the code:

func proximityChanged(notification: NSNotification) {
  if let device = notification.object as? UIDevice {
    println("\(device) detected!")
  }
}
        
func activateProximitySensor() {
  let device = UIDevice.currentDevice()
  device.proximityMonitoringEnabled = true
  if device.proximityMonitoringEnabled {
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "proximityChanged:", name: "UIDeviceProximityStateDidChangeNotification", object: device)
    }
  }
}

and in the viewDidLoad:

override func viewDidLoad() {
  super.viewDidLoad()
  activateProximitySensor()
}

Hope it helps!
