How to fix the error begin LocationUpdates? - ios

Question

I'm working on an App that shows the user's location and other Annotations.
I'm following a Youtube Tutorial to show the user's location.
(If you want to look at the tutorial). here: https://www.youtube.com/watch?v=SayMogu530A&t=132s
(I'm on 18:55 min right now.)
My code:
import UIKit
import MapKit
class ViewController: UIViewController {
private let locationManager = CLLocationManager()
private var currentCoordinate: CLLocationCoordinate2D?
#IBOutlet weak var mapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
configerLocationServices()
}
private func configerLocationServices() {
locationManager.delegate = self
let status = CLLocationManager.authorizationStatus()
if status == .notDetermined {
locationManager.requestWhenInUseAuthorization()
} else if status == .authorizedAlways || status == .authorizedWhenInUse {
beginLocationUpdates(LocatioManager: locationManager)
}
}
private func beginLocationUpdates(LocatioManager: CLLocationManager) {
mapView.showsUserLocation = true
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.startUpdatingLocation()
}
private func zoomToLastestLocation(with coordinate: CLLocationCoordinate2D) {
let zoomRegion = MKCoordinateRegion(center: coordinate, latitudinalMeters: 10000, longitudinalMeters: 10000)
mapView.setRegion(zoomRegion, animated: true)
}
}
extension ViewController: CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("Did get latest Location")
guard let latestLocation = locations.first else { return }
if currentCoordinate == nil {
zoomToLastestLocation(with: latestLocation.coordinate)
}
currentCoordinate = latestLocation.coordinate
}
}
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
print("The Status changed")
if status == .authorizedAlways || status == .authorizedWhenInUse {
beginLocationUpdates(locationManager: manager) //Error: Cannot find'beginLocationUpdates' in scope
}
}
I don't know what I'm doing wrong. The guy in the Tutorial hasn't the problem.
Thank you in advance :)

It's typing mistake. You have to write the function inside the extension and use the correct parameter name.
class ViewController: UIViewController {
private let locationManager = CLLocationManager()
private var currentCoordinate: CLLocationCoordinate2D?
#IBOutlet weak var mapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
configerLocationServices()
}
private func configerLocationServices() {
locationManager.delegate = self
let status = CLLocationManager.authorizationStatus()
if status == .notDetermined {
locationManager.requestWhenInUseAuthorization()
} else if status == .authorizedAlways || status == .authorizedWhenInUse {
beginLocationUpdates(locationManager: locationManager) //<-- Here
}
}
private func beginLocationUpdates(locationManager: CLLocationManager) { //<-- Here
mapView.showsUserLocation = true
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.startUpdatingLocation()
}
private func zoomToLastestLocation(with coordinate: CLLocationCoordinate2D) {
let zoomRegion = MKCoordinateRegion(center: coordinate, latitudinalMeters: 10000, longitudinalMeters: 10000)
mapView.setRegion(zoomRegion, animated: true)
}
}
extension ViewController: CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("Did get latest Location")
guard let latestLocation = locations.first else { return }
if currentCoordinate == nil {
zoomToLastestLocation(with: latestLocation.coordinate)
}
currentCoordinate = latestLocation.coordinate
}
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
print("The Status changed")
if status == .authorizedAlways || status == .authorizedWhenInUse {
self.beginLocationUpdates(locationManager: manager) //<-- Here
}
}
} //<-- Here
