GPX files are used for testing locations and routes within the iOS simulator, however there is an issue with the simulator moving between waypoints at a constant speed ignoring any timestamps within the GPX file.
One workaround to this is to create a set of points in-between the waypoints to slow down the movement speed.
Here’s a Ruby based tool from appscape that automatically modifies your GPX files generating interpolated points based on your chosen speed called Gips.
This example from the readme shows how to modify a gpx file to slow the movement to 20 km/h:
You can find Gips on Github here.
A nice tool for those having issues with using GPX files in development.
