Getting the current location in "Stormy" app

Hey guys, Im trying to implement a current location function in the "Coordinate.swift" of the "Stormy" app.

However I don't want to have to initialize the Coordinate class with "fake" coordinates before I call the getCurrentLocation() function.

Any Idea how to accomplish this?

The class looks like this:

import Foundation
import CoreLocation

class Coordinate: NSObject, CLLocationManagerDelegate{

    var latitude: Double
    var longitude : Double 

    init(latitude: Double, longitude : Double) {
        self.latitude = latitude
        self.longitude = longitude

    func getCurrentLocation(){
        let locManager = CLLocationManager()
        locManager.delegate = self
        var currentLocation = CLLocation()

        if( CLLocationManager.authorizationStatus() == CLAuthorizationStatus.authorizedWhenInUse ||
            CLLocationManager.authorizationStatus() == CLAuthorizationStatus.authorizedAlways){
            currentLocation = locManager.location!

        self.latitude = currentLocation.coordinate.latitude
        self.longitude = currentLocation.coordinate.longitude



extension Coordinate{
    override var description: String {
        return "\(latitude),\(longitude)"

I don't want to do this:

let coordinate = Coordinate(latitude: 00.0, longitude: 00.0)

I've done a tutorial where you create a weather app with location services and I think I had to tell the simulator to use locations that I provided. I went through the simulator and setup some but it gives you apple HQ standard.

I would create a different model that would handle the fetching of the location that uses delegation to pass on a Coordinate object that it creates when a new location is detected.

import Foundation
import CoreLocation

protocol LocationManagerDelegate: class {

    // Passing in a coordinate to the delegate method
    func locationDidUpdate(with location: Coordinate)

class LocationManager: NSObject {
    let locationManager = CLLocationManager()
    weak var delegate: LocationManagerDelegate?

    override init() {
        self.locationManager.delegate = self
        self.locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers

    func getUserPermission() {
        if CLLocationManager.authorizationStatus() == .notDetermined || CLLocationManager.authorizationStatus() == .denied {

extension LocationManager: CLLocationManagerDelegate {

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        if status == .authorizedAlways {

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.first {

            // Create the coordinate from the location
            let coordinate = Coordinate(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)

            // Pass the coordinate into the delegate method
            self.delegate?.locationDidUpdate(with: coordinate)

    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {

Conforming to the LocationManagerDelegate:

    let locationManager = LocationManager()
    // Other properties...

    override viewDidLoad() {
        locationManager.delegate = self

    // Other methods...

extension VIEW-CONTROLLER: LocationManagerDelegate {
    func locationDidUpdate(with location: Coordinate) {
        // Use the coordinate you fetched.
