Change CLLocationCoordinate2DMake With array by indexPath

Im trying to code the CLLocationCoordinate2DMake to change by an array so the lat and long will change depending on the indxPath ... like i tried here:

var Longitude = ["32.101145","32.074961","",""]
var Latitude = ["34.775163","34.781679","","",""]


//What i tried :

    let LightHouseLocation = CLLocationCoordinate2DMake(Longitude[indexPath.row],Latitude[indexPath.row])
            // Drop a pin

but of course its throwing errors on me . i will be grateful if anyone could help me, Thank you .

This is how I would do it.

class ViewController: UIViewController {

    @IBOutlet weak var map: MKMapView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        var coordinates = Array<CLLocationCoordinate2D>()

        coordinates.append(CLLocationCoordinate2DMake(32.101145, 32.074961))

        coordinates.append(CLLocationCoordinate2DMake(34.775163, 34.781679))

        let pins = coordinates.map { (coordinate) -> MKPointAnnotation in

            let pin = MKPointAnnotation()

            pin.coordinate = coordinate

            return pin
        }

        self.map.addAnnotations(pins)
    }
}
