SwiftUI - 从用户的位置获取城市/地区信息

Question

我目前能够确定用户的纬度/经度并访问坐标。我将如何对坐标进行反向地理编码以确定用户当前所在的城市以便我可以显示它？

这是我当前的 LocationManager 文件

import Foundation
import MapKit

class LocationManager: NSObject, ObservableObject {

private let locationManager = CLLocationManager()
@Published var location: CLLocation? = nil

override init() {
    super.init()
    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    self.locationManager.distanceFilter = kCLDistanceFilterNone
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()
    }
}


class ViewController: UIViewController, CLLocationManagerDelegate {

    let locationManager = CLLocationManager()

override func viewDidLoad() {
    super.viewDidLoad()
    
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.delegate = self
}

// MARK: - CLLocationManagerDelegate
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
    switch status {
    case .notDetermined:
        print("notDetermined")
        manager.requestWhenInUseAuthorization()
    default:
        break
        }
    }
}

extension LocationManager: CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    
    guard let location = locations.last else {
        return
    }
    
    self.location = location
}


}

我想将城市信息传递给我的一个视图，并以文本元素的形式输出城市。即“探索奥兰多”

您可以为此使用 CLGeocoder

// Add below code to get address for touch coordinates.
        let geoCoder = CLGeocoder()
        let location = CLLocation(latitude: YOUR_LATITUDE, longitude: YOUR_LONGITUDE)
        geoCoder.reverseGeocodeLocation(location, completionHandler:
            {
                placemarks, error -> Void in

                // Place details
                guard let placeMark = placemarks?.first else { return }

                // Location name
                if let locationName = placeMark.location {
                    print(locationName)
                }
                // Street address
                if let street = placeMark.thoroughfare {
                    print(street)
                }
                // City
                if let city = placeMark.subAdministrativeArea {
                    print(city)
                }
                // Zip code
                if let zip = placeMark.isoCountryCode {
                    print(zip)
                }
                // Country
                if let country = placeMark.country {
                    print(country)
                }
        })
