如何在iPhone应用程序中实现GPS？

import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {
    let locationManager = CLLocationManager()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager.delegate = self
    }
}

func requestLocationPermission() {
    if CLLocationManager.authorizationStatus() == .notDetermined {
        locationManager.requestWhenInUseAuthorization()
    }
}

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