Obtaining iPhone Latitude & Longitude - ios

Question

I've been attempting to retrieve a iPhone's latitude and longitude for purposes of passing to an external function in order to geotag something. However, I've been rather unsuccessful. Here is the code I'm working with right now.
let locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.locationManager.requestAlwaysAuthorization()
self.locationManager.requestWhenInUseAuthorization()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func findMyLocation (sender:AnyObject)
{
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.startUpdatingLocation()
}
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!)
{
CLGeocoder().reverseGeocodeLocation(manager.location, completionHandler: {(placemarks, error)->Void in
if error == nil
{
println("Reverse geocoder failed with error " + error.localizedDescription)
return
}
if placemarks.count > 0
{
let pm = placemarks[0] as CLPlacemark
self.displayLocationInfo(pm)
}
else
{
println("Problem with the data received from geocoder")
}
})
}
func displayLocationInfo(placemark: CLPlacemark) {
//stop updating location to save battery life
locationManager.stopUpdatingLocation()
if (placemark.postalCode != nil)
{
println(placemark.postalCode)
println("just tried to print placemark's postal code")
}
//println(placemark.locality ? placemark.locality : "")
//println(placemark.postalCode ? placemark.postalCode : "")
//println(placemark.administrativeArea ? placemark.administrativeArea : "")
//println(placemark.country ? placemark.country : "")
}
func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!)
{
println("Error while updating location " + error.localizedDescription)
}
As of now, I get pretty much nothing when I run the program. I have a little button that says "Find Me", and upon clicking, nothing pops up in the output box. I have the iOS Simulator's Debug location set to "Apple", and I've previously tried always enabling location services in settings on the simulator when trying to run the program (although currently it's not showing my app and the option to do so).
I really just want to get a double value for latitude and longitude, and if there's a simple something that'd be great.

You should only request one type of authorization. Pick the one that makes the most sense for the user experience of your app.
You are probably missing your purpose string, which is now required to activate location services. Add one of the following keys to your Info.plist:
NSLocationAlwaysUsageDescription - if requesting Always permission
NSLocationWhenInUseUsageDescription - if requesting WhenInUse permission
The value of the key should be a string that explains why you want location permissions.
