因此，我正在处理一个问题，即我所拥有的LocationManager文件和didUpdateLocations函数在应用程序启动时被多次调用，我无法找出导致此问题的原因。
所以我有下面的LocationManager：

import Foundation
import CoreLocation
import MapKit

final class LocationManager: NSObject, ObservableObject, CLLocationManagerDelegate {
    
    @Published var userLocation: CLLocation?
    @Published var defaultRegion: MKCoordinateRegion?
    @objc static let getInstance = LocationManager()
    private let locationManager = CLLocationManager()

    override init() {
        super.init()
        locationManager.delegate = self
        log.info("\n 🟢: (LocationManager) - Initialize Location Services inside init()")
    }
    
    func startUpdatingLocation() {
      locationManager.delegate = self
      locationManager.requestWhenInUseAuthorization()
      locationManager.startUpdatingLocation()
    }
    
    func requestLocation() {
        locationManager.requestLocation()
    }
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        guard let location = locations.last else { return }
        DispatchQueue.main.async {
            self.userLocation = location
            log.info("\n 🟡: (LocationManager) - Setup new location as: \(location)")
            self.defaultRegion = MKCoordinateRegion(center: location.coordinate, span: USER_LOCATION_SPAN)
            log.info("\n 🟡: (LocationManager) - Setup default region as \(location.coordinate.latitude) and \(location.coordinate.longitude).")
            self.locationManager.stopUpdatingLocation()
            log.info("\n 🟡: (LocationManager) - Stop updating the location.")
        }
    }
}

然后，我在两个名为MapUIView和MapUIView2的单独视图文件中使用它，并且在这两个文件中都有以下对象：
@ObservedObject var locationManager = LocationManager.getInstance
这会导致didUpdateLocations中的DispatchQueue.main.async在应用程序启动时运行两次-这是正常行为吗？或者，didUpdateLocations是否可能只运行一次，但处理多个视图？
