didUpdateLocations never called

Also make sure you have set the custom location to simulator as by default it will be None ... In the simulator go to Debug -> Location-> .

It should also be noted that locationManager:didFailWithError: will run if the location is not set in the simulator, as you'd expect.

for me worked:

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    print("locationManager update")
}

instead of this

private func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    print("locationManager update")
}

where do you start the location update ? for example:

//location manager
    lazy var locationManager: CLLocationManager = {
        var _locationManager = CLLocationManager()
        _locationManager.delegate = self
        _locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
        _locationManager.activityType = . automotiveNavigation
        _locationManager.distanceFilter = 10.0  // Movement threshold for new events
        _locationManager.allowsBackgroundLocationUpdates = true // allow in background

        return _locationManager
    }()


    if CLLocationManager.locationServicesEnabled() {
                locationManager.startUpdatingLocation() // start location manager

            }

here is a working conroller code: also important to to set up Custom iOS Target Properties.

Add these two lines to the Info.plist:

NSLocationWhenInUseUsageDescription

NSLocationAlwaysUsageDescription

//
//  ViewController.swift
//  LocationTest2


import UIKit
import CoreLocation

class ViewController: UIViewController {

    //location manager
    lazy var locationManager: CLLocationManager = {
        var _locationManager = CLLocationManager()
        _locationManager.delegate = self
        _locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
        _locationManager.activityType = . automotiveNavigation
        _locationManager.distanceFilter = 10.0  // Movement threshold for new events
      //  _locationManager.allowsBackgroundLocationUpdates = true // allow in background

        return _locationManager
    }()

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)

        //allow location use
        locationManager.requestAlwaysAuthorization()

        print("did load")
        print(locationManager)

        //get current user location for startup
       // if CLLocationManager.locationServicesEnabled() {
            locationManager.startUpdatingLocation()
       // }
    }
}


// MARK: - CLLocationManagerDelegate
extension ViewController: CLLocationManagerDelegate {

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

        for location in locations {

            print("**********************")
            print("Long \(location.coordinate.longitude)")
            print("Lati \(location.coordinate.latitude)")
            print("Alt \(location.altitude)")
            print("Sped \(location.speed)")
            print("Accu \(location.horizontalAccuracy)")

            print("**********************")


        }
    }

}

A very subtle cause for this bug in Swift code. Don't define the delegate call didUpdateLocations as private or fileprivate. The location manager won't be able to find or call it if you do.

Good:

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

Bad:

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