Problem with WatchKit CoreLocation

Question

I am trying to read the current location coordinates in WatchKitExtension ExtensionDelegate. It does, although it does not return any value.

The same code used by WatchKitExtension InterfaceController returns the location. (tried this out of desperation, as I could not find the error in the code)

I will need to execute this code in ExtensionDelegate, since I would like to pass the resulting location to ClockKit detuning.

Here's the code in ExtensionDelegate: (after self.locationManager.requestLocation (), the delegate functions didUpdateLocation / didFailWithError are not called)

import WatchKit
import CoreLocation



class ExtensionDelegate: NSObject, WKExtensionDelegate, CLLocationManagerDelegate {

    private let locationManager = CLLocationManager()

    override init() {
        print("ExtensionDelegate: \(NSDate())  - init")
        super.init()
        self.getLocation()
    }


    func getLocation(){
        print("ExtensionDelegate: \(NSDate())  - getLocation")
        locationManager.delegate = self
        locationManager.requestAlwaysAuthorization()
        locationManager.requestWhenInUseAuthorization()
        locationManager.requestLocation()
    }

...


    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        print("ExtensionDelegate: \(NSDate())  - locationManager didUpdateLocations")

        guard let mostRecentLocation = locations.last else { return }
        let place = mostRecentLocation.coordinate
        print("\(place)")
        manager.stopUpdatingLocation()
    }


    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
        print("ExtensionDelegate: \(NSDate())  - locationManager didFailWithError")
        print("CL failed: \(error)")
    }


}

Here is the same code in InterfaceController and it works fine (didUpdateLocation is called):

import WatchKit
import Foundation
import CoreLocation

class InterfaceController: WKInterfaceController, CLLocationManagerDelegate {

    private let locationManager = CLLocationManager()

    override func awakeWithContext(context: AnyObject?) {
        print("InterfaceController: \(NSDate())  - awakeWithContext")
        super.awakeWithContext(context)
        self.getLocation()
    }

    func getLocation(){
        print("InterfaceController: \(NSDate())  - getLocation")
        locationManager.delegate = self
        locationManager.requestAlwaysAuthorization()
        locationManager.requestWhenInUseAuthorization()
        locationManager.requestLocation()
    }

   ...

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        print("InterfaceController: \(NSDate())  - locationManager didUpdateLocations")

        guard let mostRecentLocation = locations.last else { return }
        let place = mostRecentLocation.coordinate
        print("\(place)")
        manager.stopUpdatingLocation()
    }


    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
        print("InterfaceController: \(NSDate())  - locationManager didFailWithError")
        print("CL failed: \(error)")
    }
}
