• Just call the below function in your ViewController Class

import CoreLocation

class ViewController: UIViewController {

var userCoords = CLLocationCoordinate2D(latitude: 0, longitude: 0)

override func viewDidLoad() {
    super.viewDidLoad()
    
    //Fetch User Current Location
    self.fetchUserCurrentLocation()
}

func fetchUserCurrentLocation() {
    
    let locationFetch = FetchLocation.SharedManager
    locationFetch.parentObject = self
    locationFetch.startUpdatingLocation()
    locationFetch.completionBlock = { [unowned self] (userCoordinates, error) in
        
        if error != nil {
            print(error?.localizedDescription ?? "")
        }
        
        if let userLocation = userCoordinates as? CLLocationCoordinate2D {
            print(userLocation.latitude, userLocation.longitude)
            self.userCoords = userLocation
        }
