Parse PFGeoPoint save location getting started - swift

Question

Im trying to create an app with two user types...one sends a location and the other user type (on a different device) searches an area and finds the closest user.
I have been on parse's website and stack overflow...they all seem to start in the middle. I would like to have somebody explain the first steps
Heres my code
import UIKit
import MapKit
import CoreLocation
import Parse
class ViewController: UIViewController, MKMapViewDelegate,
CLLocationManagerDelegate, UISearchBarDelegate,
UIGestureRecognizerDelegate
{
#IBOutlet weak var photographer1: UIButton!
#IBOutlet weak var buyer1: UIButton!
#IBOutlet weak var mapView: MKMapView!
#IBOutlet weak var searchBar: UISearchBar!
let locationManager = CLLocationManager()
var searchController:UISearchController!
var annotation:MKAnnotation!
var localSearchRequest:MKLocalSearchRequest!
var localSearch:MKLocalSearch!
var localSearchResponse:MKLocalSearchResponse!
var error:NSError!
var pointAnnotation:MKPointAnnotation!
var pinAnnotationView:MKPinAnnotationView!

}
// to run the animation this sec of code checks if the region was changed
var mapChangedFromUserInteraction = false
func mapViewRegionDidChangeFromUserInteraction() -> Bool {
let view = self.mapView.subviews[0]
// Look through gesture recognizers to determine whether this region change is from user interaction
if let gestureRecognizers = view.gestureRecognizers {
for recognizer in gestureRecognizers {
if( recognizer.state == UIGestureRecognizerState.Began || recognizer.state == UIGestureRecognizerState.Ended ) {
