How do I track significant location changes in Swift?

Tracking significant location changes in Swift allows you to monitor a user's location efficiently without consuming too much battery. This functionality is particularly useful for apps that need to update location, such as for navigation or geofencing.

        import UIKit
        import CoreLocation

        class LocationManager: NSObject, CLLocationManagerDelegate {
            private var locationManager: CLLocationManager?

            override init() {
                super.init()
                locationManager = CLLocationManager()
                locationManager?.delegate = self
                locationManager?.requestAlwaysAuthorization()
            }

            func startTrackingSignificantLocationChanges() {
                locationManager?.startMonitoringSignificantLocationChanges()
            }

            func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
                guard let newLocation = locations.last else { return }
                print("Significant location change detected: \(newLocation.coordinate.latitude), \(newLocation.coordinate.longitude)")
            }

            func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
                print("Failed to find user's location: \(error.localizedDescription)")
            }
        }

        // Usage
        let locationManager = LocationManager()
        locationManager.startTrackingSignificantLocationChanges()
