获取用户当前位置/坐标

 override func viewDidLoad() {

    super.viewDidLoad()       
    locationManager.requestWhenInUseAuthorization();     
    if CLLocationManager.locationServicesEnabled() {
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
        locationManager.startUpdatingLocation()
    }
    else{
        print("Location service disabled");
    }
  }

这是您的视图加载方法，还应在ViewController类中包括mapStart更新方法，如下所示。

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    var locValue : CLLocationCoordinate2D = manager.location.coordinate;
    let span2 = MKCoordinateSpanMake(1, 1)    
    let long = locValue.longitude;
    let lat = locValue.latitude;
    print(long);
    print(lat);        
    let loadlocation = CLLocationCoordinate2D(
                    latitude: lat, longitude: long            

   )     

    mapView.centerCoordinate = loadlocation;
    locationManager.stopUpdatingLocation();
}

不要忘记在项目中添加CoreLocation.Framework和MapKit.Framework（自XCode 7.2.1起不再需要）

import Foundation
import CoreLocation

enum Result<T> {
  case success(T)
  case failure(Error)
}

final class LocationService: NSObject {
    private let manager: CLLocationManager

    init(manager: CLLocationManager = .init()) {
        self.manager = manager
        super.init()
        manager.delegate = self
    }

    var newLocation: ((Result<CLLocation>) -> Void)?
    var didChangeStatus: ((Bool) -> Void)?

    var status: CLAuthorizationStatus {
        return CLLocationManager.authorizationStatus()
    }

    func requestLocationAuthorization() {
        manager.delegate = self
        manager.desiredAccuracy = kCLLocationAccuracyBest
        manager.requestWhenInUseAuthorization()
        if CLLocationManager.locationServicesEnabled() {
            manager.startUpdatingLocation()
            //locationManager.startUpdatingHeading()
        }
    }

    func getLocation() {
        manager.requestLocation()
    }

    deinit {
        manager.stopUpdatingLocation()
    }

}

 extension LocationService: CLLocationManagerDelegate {
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        newLocation?(.failure(error))
        manager.stopUpdatingLocation()
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.sorted(by: {$0.timestamp > $1.timestamp}).first {
            newLocation?(.success(location))
        }
        manager.stopUpdatingLocation()
    }

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        switch status {
        case .notDetermined, .restricted, .denied:
            didChangeStatus?(false)
        default:
            didChangeStatus?(true)
        }
    }
}

需要在所需的ViewController中编写此代码。

 //NOTE:: Add permission in info.plist::: NSLocationWhenInUseUsageDescription


let locationService = LocationService()

 @IBAction func action_AllowButtonTapped(_ sender: Any) {
     didTapAllow()
 }

 func didTapAllow() {
     locationService.requestLocationAuthorization()
 }

 func getCurrentLocationCoordinates(){
   locationService.newLocation = {result in
     switch result {
      case .success(let location):
      print(location.coordinate.latitude, location.coordinate.longitude)
      case .failure(let error):
      assertionFailure("Error getting the users location \(error)")
   }
  }
}

func getCurrentLocationCoordinates() {
    locationService.newLocation = { result in
        switch result {
        case .success(let location):
            print(location.coordinate.latitude, location.coordinate.longitude)
            CLGeocoder().reverseGeocodeLocation(location, completionHandler: {(placemarks, error) -> Void in
                if error != nil {
                    print("Reverse geocoder failed with error" + (error?.localizedDescription)!)
                    return
                }
                if (placemarks?.count)! > 0 {
                    print("placemarks", placemarks!)
                    let pmark = placemarks?[0]
                    self.displayLocationInfo(pmark)
                } else {
                    print("Problem with the data received from geocoder")
                }
            })
        case .failure(let error):
            assertionFailure("Error getting the users location \(error)")
        }
    }
}

所有之前的答案都没有正确地按照正确的步骤进行。在设置CLLocationManager时，您不需要最初调用CLLocationManager.locationServicesEnabled()或locationManager.requestWhenInUseAuthorization()。并且在验证您是否有授权之前，不应该调用startUpdatingLocation()。

要开始，请添加所需的隐私设置（如果尚未完成）。选择您的应用程序目标并转到“信息”选项卡。在“自定义iOS目标属性”部分下右键单击并选择“添加行”。向下滚动到“隐私”条目，然后选择以下任一项：

• “使用应用程序期间位置权限说明”
• “始终允许访问位置权限说明”
• “始终和使用应用程序期间位置权限说明”

根据您的应用程序需求选择相应的选项。对于值，请确保输入一个句子，解释为用户为什么您的应用程序需要访问他们的位置。如果给定的描述对用户没有用处，则可能会导致您的应用被苹果拒绝。

然后，使用以下（详细注释的）代码作为在视图控制器中获取用户位置的示例：

import UIKit
import CoreLocation

class ViewController: UIViewController {
    var locationManager: CLLocationManager!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Setup the location manager
        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation // Or other desired accuracy

        // That's it for the initial setup. Everything else is handled in the
        // locationManagerDidChangeAuthorization delegate method.
    }
}

extension ViewController: CLLocationManagerDelegate {
    // This is called as soon as the location manager is setup (in viewDidLoad)
    // This is called when the user responds to the privacy dialog
    // This is called if the user changes the privacy setting in the Settings app
    func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {
        switch manager.authorizationStatus {
        case .notDetermined:
            // Request the appropriate authorization based on the needs of the app
            manager.requestWhenInUseAuthorization()
            // manager.requestAlwaysAuthorization()
        case .restricted:
            print("Sorry, restricted")
            // Optional: Offer to take user to app's settings screen
        case .denied:
            print("Sorry, denied")
            // Optional: Offer to take user to app's settings screen
        case .authorizedAlways, .authorizedWhenInUse:
            // The app has permission so start getting location updates
            manager.startUpdatingLocation()
        @unknown default:
            print("Unknown status")
        }
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        print("Received \(locations.count) locations")

        // Some location updates can be invalid or have insufficient accuracy.
        // Find the first location that has sufficient horizontal accuracy.
        // If the manager's desiredAccuracy is one of kCLLocationAccuracyNearestTenMeters,
        // kCLLocationAccuracyHundredMeters, kCLLocationAccuracyKilometer, or kCLLocationAccuracyThreeKilometers
        // then you can use $0.horizontalAccuracy <= manager.desiredAccuracy. Otherwise enter the number of meters desired.
        if let location = locations.first(where: { $0.horizontalAccuracy <= 40 }) {
            print("Good location found: \(location)")
            // Call the following if you don't need any more updates
            manager.stopUpdatingLocation()

            // Do something useful with the found location
            // - show on a map
            // - Reverse geocode to get the address
            // - send to server
        }
    }

    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print("Location manager error: \(error)")
    }
}
