如何将坐标从diupdateLocation传递到某个视图控制器?

我正在努力 LocationService 类,它将传递用户坐标,因此它将可用于多个视图控制器

import UIKit
import CoreLocation

class LocationService: NSObject {
    let manager = CLLocationManager()

    override init() {
        super.init()

        manager.delegate = self
        manager.desiredAccuracy = kCLLocationAccuracyBest
        manager.startUpdatingLocation()
    }

    func getPermission() {
        // to ask permission to the user by showing an alert (the alert message is available on info.plist)
        if CLLocationManager.authorizationStatus() == .notDetermined {
            manager.requestWhenInUseAuthorization()
        }
    }

    func checkLocationAuthorizationStatus() -> CLAuthorizationStatus{
        return CLLocationManager.authorizationStatus()
    }
}

extension LocationService : CLLocationManagerDelegate {

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        if status == .authorizedWhenInUse {
            manager.requestLocation()
        }
    }

    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print("location is not available: \(error.localizedDescription)")
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

        guard let userLocation = locations.first else {return}

        if userLocation.horizontalAccuracy > 0 {
            manager.stopUpdatingLocation()

            let coordinate = Coordinate(location: userLocation)
            // how to convey this coordinate for several view controller?
        } 
    }
}

正如你在 didUpdateLocations 来自的方法 CLLocationManagerDelegate ,需要一些时间来生成坐标。

但我不知道如何传递用户坐标,我认为它将使用完成处理程序,但我不知道如何得到它。

所以说在homevc里,我会这么叫的 位置服务 获取用户坐标

import UIKit

class HomeVC: UIViewController {

    let locationService = LocationService()

    override func viewDidLoad() {
        super.viewDidLoad()

        // get coordinate, something like this
       locationService.getCoordinate()
    }
}
