Location Services not working in iOS 11

Question

I just rebuilt my app with the iOS 11 SDK in an attempt to remove the blue banner that is now always appearing. I thought - \"Brilliant, that worked\", only to

Answer 1

Follow these steps:

I ran into the same issue with an app that needed "Always Authorization", and resolved it by following these steps:

1. Add NSLocationWhenInUseUsageDescription key to Info.plist

2. Add NSLocationAlwaysAndWhenInUseUsageDescription to Info.plist

3. Add NSLocationAlwaysUsageDescription to Info.plist (to support < iOS 11)

4. Call requestWhenInUseAuthorization() BEFORE requestAlwaysAuthorization()

You cannot execute requestAlwaysAuthorization() before requestWhenInUseAuthorization(). You must escalate to that permission level. Once I made these changes, location updates started working properly again.

Answer 2

Tested on iOS 12.2 with Swift 5

Step 1. you must add following privacy permissions in plist file

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Application requires user’s location for better user experience.</string>

<key>NSLocationAlwaysUsageDescription</key>
<string>Application requires user’s location for better user experience.</string>

<key>NSLocationWhenInUseUsageDescription</key>
<string>Application requires user’s location for better user experience.</string>

Step 2. make sure you have following swift code to get current locations

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    // MARK: Variables declearations
    @IBOutlet weak var mapView: MKMapView!
    var locationManager: CLLocationManager!

    // MARK: View Controller life cycle methods
    override func viewDidLoad() {
        super.viewDidLoad()
        //TODO: Make user you must add following three privacy permissions in plist
        //NSLocationWhenInUseUsageDescription
        //NSLocationAlwaysAndWhenInUseUsageDescription
        //NSLocationAlwaysUsageDescription

        getCurrentLocation()
    }

    func getCurrentLocation()
    {
        if (CLLocationManager.locationServicesEnabled())
        {
            locationManager = CLLocationManager()
            locationManager.delegate = self
            locationManager.desiredAccuracy = kCLLocationAccuracyBest
            locationManager.requestAlwaysAuthorization()
            locationManager.startUpdatingLocation()
        }
    }

    // MARK: Location Manager Delegate methods
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
    {
        let locationsObj = locations.last! as CLLocation
        print("Current location lat-long is = \(locationsObj.coordinate.latitude) \(locationsObj.coordinate.longitude)")
        showOnMap(location: locationsObj)
    }
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print("Get Location failed")
    }

    func showOnMap(location: CLLocation )
    {
        let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
        let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
        mapView.setRegion(region, animated: true)
    }
}
