Display a user's approximate location

A newer version of the Maps SDK is available

This page uses v6.4.1 of the Mapbox Maps SDK. A newer version of the SDK is available. Learn about the latest version, v11.3.0, in the Maps SDK documentation.

Displaying approximate user location is only available on iOS 14+. For more information about requesting location data from users, see Apple's location services guide.

import Mapbox

class ViewController: UIViewController, MGLMapViewDelegate {
var mapView: MGLMapView?
var preciseButton: UIButton?

override func viewDidLoad() {

let mapView = MGLMapView(frame: view.bounds)
mapView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
mapView.delegate = self
mapView.showsUserLocation = true
self.mapView = mapView


In order to enable the alert that requests temporary precise location,
please add the following key to your info.plist

You must then add
as a key in the Privacy - Location Temporary Usage Description Dictionary
