Building iOS Map Applications in Swift 3 (2)

Normally, the general steps for getting longitude and latitude of user location.

1. Add CoreLocation.framework to BuildPhases -> Link Binary With Libraries (no longer necessary as of XCode 7.2.1)
2. Add import CoreLocation to your class - probably ViewController.swift
3. Add CLLocationManagerDelegate to your class declaration
4. Add
   NSLocationWhenInUseUsageDescription and
   NSLocationAlwaysUsageDescription
   to plist
5. Initialize location manager :

locationManager = CLLocationManager()
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()

get User Location By:

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    var userLocation:CLLocation = locations[0] as! CLLocation
    let long = userLocation.coordinate.longitude;
    let lat = userLocation.coordinate.latitude;
    //Do What ever you want with it       
}
