How to cek current longitude and latitude Swift 4

1.  Get data longitude and latitude First you need to set allowance to receive User's GPS in the info.plist.

Set: NSLocationWhenInUseUsageDescription with a random String. And/or: NSLocationAlwaysUsageDescription with a random String.

Then:

import UIKit
import MapKit

class ViewController: UIViewController {

    var locManager = CLLocationManager()
    var currentLocation: CLLocation!

    override func viewDidLoad() {
        super.viewDidLoad()
        locManager.requestWhenInUseAuthorization()

        if (CLLocationManager.authorizationStatus() == CLAuthorizationStatus.authorizedWhenInUse ||
            CLLocationManager.authorizationStatus() == CLAuthorizationStatus.authorizedAlways){
            currentLocation = locManager.location
            print(currentLocation.coordinate.latitude)
            print(currentLocation.coordinate.longitude)
        }
    }
}
