CLLocationManager 不改变坐标？

Question

我有两个不同的 classes，其中之一 LocationService 仅用于确定位置。问题是我不知道为什么它不更新坐标变量。

ViewController:

import UIKit

class ViewController: UIViewController {
    var coords: (lat: Double, long: Double) = (0,0)
    var tracking = LocationServices()

    override func viewDidLoad() {
        super.viewDidLoad()

        tracking.startTracking()
        tracking.getLocations()
        coordinat = tracking.coordinates
        retreiveWeatherForecast()
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }   
    // retrieveWeatherForecast functions

和简单的定位服务class:

import UIKit
import CoreLocation

class LocationServices: NSObject, CLLocationManagerDelegate {

    var locationManager = CLLocationManager()
    var coordinates: (lat: Double, long: Double) = (0,0)

    func startTracking() {  

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

    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
        locationManager.stopUpdatingLocation()
        print(error)
    }

    func getLocations() {

        #if os (ios)
            func locationManager(manager:CLLocationManager, didUpdateLocations locations:[AnyObject]) {
                //println("locations = \(locationManager)")
                var latValue = locationManager.location.coordinate.latitude
                var lonValue = locationManager.location.coordinate.longitude
                coordinates = (latValue,lonValue)
                println(latValue)
                println(lonValue)

            }
        #endif
    }
}

当我构建它时，它 returns 天气默认坐标 = (0,0)。

好吧，我不小心让它起作用了。据我了解，问题出在这里：func locationManager(manager:CLLocationManager, didUpdateLocations locations:[AnyObject]) 位置必须是 CLLocation 类型，而不是 AnyObject。我正在使用 Swift 2.0。
