如何使用SwiftUI获取当前位置？

import CoreLocation

class LocationManager: NSObject, CLLocationManagerDelegate {
    let manager = CLLocationManager()
    
    override init() {
        super.init()
        manager.delegate = self
    }
}

func requestLocationAuthorization() {
    manager.requestWhenInUseAuthorization()
}

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if let location = locations.last {
        // 处理获取到的位置信息
        let latitude = location.coordinate.latitude
        let longitude = location.coordinate.longitude
        // ...
    }
}

struct ContentView: View {
    @StateObject var locationManager = LocationManager()
    
    var body: some View {
        // ...
    }
}

.onAppear {
    locationManager.requestLocationAuthorization()
    locationManager.manager.startUpdatingLocation()
}
