Is it possible to get location within iOS framework?

I have created a framework in swift. But I am trying to get location values - lat and lon within the framework. The below code compiles fine but the location values are not getting populated. I have already added NSlocationWheninUseUSageDescription key to the info.plist.

Can some tell me is it even possible to get location values within the framework? If yes, then what should be done here?

import Foundation
import CoreLocation


public class FrameworkInit : NSObject, CLLocationManagerDelegate {


var locationManager = CLLocationManager()
var lat = ""
var long = ""
var locflag = false
var _appKey = ""

func fetchLocation()
{
    println("fetch loc called....")
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestWhenInUseAuthorization()
    locationManager.startUpdatingLocation()
}

public func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!)
{
    var locValue:CLLocationCoordinate2D = manager.location.coordinate
    lat = locValue.latitude.description
    long = locValue.longitude.description
    println("lat.....\(lat)   \nlong...... \(long)")
    self.locationManager.stopUpdatingLocation()
    if !locflag {

        SPDeviceRegister().saveDataOnDevice(_appKey, lat: lat, long: long)

        SPReceiver().thresholdValueSetter()

    }
    locflag = true
}

 public func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!)
{
    println("Error:" + error.localizedDescription)
    if !locflag {

        SPDeviceRegister().saveDataOnDevice(_appKey, lat: "0.0", long: "0.0")

        SPReceiver().thresholdValueSetter()
    }
    locflag = true
}


public init(appKey: String)
{
    super.init()
    _appKey = appKey
    self.fetchLocation()
}
}
