swift - didUpdateLocations Not Being Called - ios

Question

I'm working on an app that requires getting the user's current coordinates. I was planning on doing this through CLLocationManager's didUpdateLocations method. For some reason, didUpdateLocations is not being executed. However, it appears that locationManager.startUpdatingLocation() is being called successfully. None of the other possible solutions I've seen on this site have worked for me. I already added NSLocationAlwaysUsage to info.plist. Here is the entirety of my code:
import UIKit
import MapKit
import CoreLocation
var region: MKCoordinateRegion!
class ViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate {
#IBOutlet weak var map: MKMapView!
var locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
self.locationManager.requestAlwaysAuthorization()
self.locationManager.requestWhenInUseAuthorization()
switch CLLocationManager.authorizationStatus() {
case .authorizedWhenInUse, .authorizedAlways:
if CLLocationManager.locationServicesEnabled() {
locationManager.startUpdatingLocation()
print("Updating location now")
}
case .notDetermined:
locationManager.requestAlwaysAuthorization()
case .restricted, .denied:
print("User must enable access in settings")
break
}
if (region == nil){
}
else {
map.setRegion(region!, animated: true)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("Got location")
let userLocation:CLLocation = locations[0]
let lat:CLLocationDegrees = userLocation.coordinate.latitude
let long:CLLocationDegrees = userLocation.coordinate.longitude
let currentPos:CLLocationCoordinate2D = CLLocationCoordinate2DMake(lat, long)
didUpdateRegion(position: currentPos)
print(lat)
print(long)
}
func didUpdateRegion(position: CLLocationCoordinate2D) {
let span = MKCoordinateSpanMake(0.075, 0.075)
region = MKCoordinateRegion(center: position, span: span)
}
func locationManager(_manager: CLLocationManager, didFailWithError error: Error) {
print(error.localizedDescription)
}
func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
switch status {
case .notDetermined:
// If status has not yet been determied, ask for authorization
manager.requestWhenInUseAuthorization()
break
case .authorizedWhenInUse:
// If authorized when in use
manager.startUpdatingLocation()
break
case .authorizedAlways:
// If always authorized
manager.startUpdatingLocation()
break
case .restricted:
print("User must activate location services in settings")
break
case .denied:
print("User must activate location services in settings")
break
default:
break
}
}
When I run this code on both the simulator and an actual device, I get the notification to allow location tracking. After accepting that, the console displays "Updating location now," but never gets to printing "Got location." Thank you for any light you can shed on this issue, I'm new to app development in general.
EDIT: I added in the entirety of my code instead of just the parts I thought were relevant. Basically, I'm trying to get the region shown on the map to follow the user. I attempt to do this by updating the variable "region" every time the didUpdateLocations function fires.

Am I getting it right and you only added one key - NSLocationAlwaysUsage?
Try to add both keys to the Info.plist:
Privacy - Location When In Use Usage Description
Privacy - Location Always Usage Description
Also, what happens if you implement this method of protocol?
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("\(error.localizedDescription)")
}
Does it print anything? Sorry, I was going to leave a comment, but I don't have enough reputation.
