title: MKpolyline not displaying correctly for given coordinates
body: <p>Im trying to draw MKpolyline using following code.</p>
  
  <pre><code>var points: [CLLocationCoordinate2D] = []
  
  let locationDetails = myArray as! [Location]
  
  for each in locationDetails{
      print("Latitude \(each.latitude) - Longitude \(each.longitude)")
      points.append(CLLocationCoordinate2DMake(each.latitude, each.longitude))
  }
  
  let centerLocation : Location = myArray.anyObject() as! Location
  let centerPoint = CLLocationCoordinate2DMake(centerLocation.latitude, centerLocation.longitude);
  
  print("POINTS \(points)")
  
  let polyline = MKPolyline(coordinates: points, count: points.count)
  mapView.add(polyline)
  
  let region = MKCoordinateRegionMakeWithDistance(centerPoint, 5000.0, 7000.0)
  mapView.setRegion(region, animated: true)
  </code></pre>
  
  <p>but im getting messy polyline. see attached Screenshot. first i thought problem with coordinates. but when i tried those lat and long with <a href="https://www.darrinward.com" rel="nofollow noreferrer">this online tool</a> it gave me perfect line with pins. <code>print</code> log the cooridnates perfectly.</p>
