Swift — Create CLLocationManager in Singleton (separate class)

Create a new file: UserLocationManager.swift

import UIKit
import CoreLocation
extension NSNotification.Name {
static let sharedLocation = NSNotification.Name("sharedLocation")
}
class LocationManager: NSObject, CLLocationManagerDelegate {
static let shared = LocationManager()
let manager = CLLocationManager()
private let notificationCenter = NotificationCenter.default
private override init() { }
func checkLocationService() {
if CLLocationManager.locationServicesEnabled() {
setupLocationManager()
checkLocationManagerAuthorization()
} else {
setupNotificationCenter(object: ["error": true])
}
}
func setupLocationManager() {
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
}
func checkLocationManagerAuthorization() {
switch authorizationStatus() {
case .notDetermined:
print("Auth: notDetermined")
manager.requestWhenInUseAuthorization()
case .authorizedAlways, .authorizedWhenInUse:
print("Auth: authorizedWhenInUse")
manager.startUpdatingLocation()
case .denied, .restricted:
print("Auth: denied")
setupNotificationCenter(object: ["error": true])
break
default:
setupNotificationCenter(object: ["error": true])
break
}
}
func authorizationStatus() -> CLAuthorizationStatus {
var status: CLAuthorizationStatus
if #available(iOS 14.0, *) {
status = CLLocationManager().authorizationStatus
} else {
status = CLLocationManager.authorizationStatus()
}
return status
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
if let location = locations.last {
let object: [String: Any] = [
"error": false,
"location": location
]
DispatchQueue.main.async {
self.setupNotificationCenter(object: object)
}
manager.stopUpdatingLocation()
}
}
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
checkLocationService()
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
manager.stopUpdatingLocation()
}
func setupNotificationCenter(object: Any? = nil) {
notificationCenter.post(name: .sharedLocation, object: object)
}
}
