Rendering a line in a map that display the movement of the user.

I am working in an app where I should track the user while is moving.
The app should render a line on the map that shows the movement (tracking) of the user.
There is an example GPX Tracker and other could be Runkeeper apps.
[https://github.com/merlos/iOS-Open-GPX-Tracker)
We are using MapKit and CoreLocation
However, when using the repository of GPX Tracker, the library GPX Core is not available within the CocoPots.

Does anyone have a posible solution to this?

Thank you!
