CLLocationManager not determining location

I'm having some trouble getting the user's current location. I realize there are many questions on this topic, but I have read them and done exactly what the Apple documentation tells me to do and still it doesn't work.

I have the following code in my MasterViewController:

class MasterViewController: UITableViewController, CLLocationManagerDelegate {

var detailViewController: DetailViewController? = nil

var locationManager:CLLocationManager!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    self.navigationItem.leftBarButtonItem = self.editButtonItem()
    let addButton = UIBarButtonItem(barButtonSystemItem: .Add, target: self, action: "printPlace:")
    self.navigationItem.rightBarButtonItem = addButton
    if let split = self.splitViewController {
        let controllers = split.viewControllers
        self.detailViewController = controllers[controllers.count-1].topViewController as? DetailViewController
    }

    if !CLLocationManager.locationServicesEnabled() {
        println("location services disabled")
    }
    locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.distanceFilter = kCLDistanceFilterNone
    locationManager.requestAlwaysAuthorization()
    locationManager.startUpdatingLocation()
}


func locationManager(manager:CLLocationManager, didUpdateLocations locations:[AnyObject]) {
    println("found location")
}

@IBAction func printPlace(sender: AnyObject) {
    let currentLocation: CLLocationCoordinate2D = locationManager.location.coordinate
    println("\(currentLocation.latitude) , \(currentLocation.longitude)")
}

I also added the NSLocationWhenInUseUsageDescription key to my info.plist. However, when I run this code, didUpdateLocations is never called, and printPlace gives a fatal error because locationManager.location is nil. Can anyone see what I'm doing wrong here?

Ah, the issue might be that you said you updated your .plist for NSLocationWhenInUseUsageDescription but in your code you call locationManager.requestAlwaysAuthorization() which is something different. You either need to add the proper one to the .plist (NSLocationAlwaysUsageDescription), or request only for when in use like this: locationManager.requestWhenInUseAuthorization().

Also, as the comment on your original post points out, it should be NSLocationWhenInUseUsageDescription, not NSLocationWhenInUsageDescription
