title: CLLocation to CLLocationCoordinate2D in swift
body: <p>Hi had lot of trouble in understanding the declaration part in swift programming.
  I have line of code <code>CLLocationCoordinate2D myCoordinate = myLocation.coordinate;</code>
  As same as I declared in Swift programming but I'm getting error</p>
  
  <pre><code>var location1:CLLocation! = locationManager1.location
  var coordinate1:CLLocationCoordinate2D = location1.coordinate
  </code></pre>
  
  <p>fatal error: Can't unwrap Optional.None</p>
