CLLocation Manager in Swift to get Location of User

Question

I am trying to convert an old app in ObjC to Swift as a practice exercise and have ran in to some issues. The way I had it in the old app, it was establishing the CLLocation Manager and then I would use:

manager = [[CLLocationManager alloc]init];
manager.delegate = self;
manager.desiredAccuracy = kCLLocationAccuracyBest;    
[manager startUpdatingLocation]

which would call automatically:

-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
}

and from there I could extract all the information I needed. But in swift, there is no autocompletion of this method and I cannot figure out how to reproduce it. The documentation says that

startUpdatingLocation()

will still be called by the delegate, but it isn't happening.

This is what I have so far:

import UIKit
import corelocation

class ViewController: UIViewController,CLLocationManagerDelegate{

@IBOutlet var gpsResult : UILabel

var manager:CLLocationManager!

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

    manager = CLLocationManager()
    manager.delegate = self
    manager.desiredAccuracy = kCLLocationAccuracyBest
    manager.startUpdatingLocation()
}

func locationManager(manager:CLLocationManager, didUpdateLocations locations:AnyObject[]) {
    println("locations = \(locations)")
    gpsResult.text = "success"
}
}

Any help or pointers on where to look would be appreciated. Thanks.

EDIT: Updated from Suggestions, but still not working

EDIT2: Seems to be some bug not allowing the method to work properly in the ViewController

Answer 1

You are missing two things. First, you have to ask for permission using requestAlwaysAuthorization or requestWhenInUseAuthorization(). So your viewDidLoad() should be like this:

var locationManager = CLLocationManager()

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

    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestAlwaysAuthorization()
    locationManager.startUpdatingLocation()
}

Second, edit your Info.plist as indicated here.
