Swift: Trying to create a locationManager class to handle location data then call it in my root view controller.

I was attempting to make a class that handles location services and call in my root view controller however in doing so My app will not load, I get a indefinite black screen w/ the exception: thread 1:EXC_BAD_ACCESS (code=2, address=0x7ff...). It seems to be accusing because in order to change objects belonging to my root view controller I created a instance of the controller. Is there a way to retrieve the label objects belonging to my root view controller without creating an instance? How do I fix this?

here's my code for the RootViewController:

import UIKit

class RootViewController: UIViewController {

@IBOutlet weak var lblCurrentLocation: UILabel!

let locationTracker = LocationTracker()

 override func viewDidLoad() {
   // Do any additional setup after loading the view, typically from a nib.


and my locationManager class:

import UIKit import Foundation import CoreLocation

class LocationTracker: NSObject, CLLocationManagerDelegate {

let locationManager = CLLocationManager()
let rootViewController = RootViewController()

func startTracking() {
  locationManager.delegate = self
  locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters


func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {

  var currentLocation: CLLocation = manager.location

  var coordinates: String = "\(currentLocation.coordinate.latitude),\(currentLocation.coordinate.longitude)"

  println(" Locations data: \(locations)")

  getLocationPlacemark(currentLocation: currentLocation)


 func displayLocationInfo  (#Placemark: CLPlacemark) {


self.rootViewController.lblCurrentLocation.text = "\(Placemark.administrativeArea), \(Placemark.locality)"

func getLocationPlacemark (#currentLocation:CLLocation)-> Void {

  CLGeocoder().reverseGeocodeLocation(currentLocation, completionHandler: { (placemark, error) -> Void in

  if error == nil && placemark.count > 0 {

    var pMark = placemark [0] as CLPlacemark

    dispatch_async(dispatch_get_main_queue(), { () -> Void in

      self.displayLocationInfo(Placemark: pMark)

    }else {

      self.rootViewController.lblCurrentLocation.text = "error!"
