iOS has a simple way to request a user's location just once, and it's called requestLocation(). Calling this method returns immediately (meaning that your code carries on executing) but when iOS has managed (or failed) to get a fix on the user's location you will be told. Below is a complete example:
import CoreLocation
import UIKit
class ViewController: UIViewController, CLLocationManagerDelegate {
let manager = CLLocationManager()
override func viewDidLoad() {
manager.delegate = self
manager.requestLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
if let location = locations.first {
print("Found user's location: \(location)")
}
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("Failed to find user's location: \(error.localizedDescription)")
}
}Did this solution work for you? Please pass it on!
