How to set fake GPS location on IOS real device
Working with GPX files with Xcode compatibility
I followed the link given by AlexWien and it was extremely useful: https://blackpixel.com/writing/2013/05/simulating-locations-with-xcode.html
But, I spent quite some time searching for how to generate .gpx files with waypoints (wpt tags), as Xcode only accepts wpt tags.
The following tool converts a Google Maps link (also works with Google Maps Directions) to a .gpx file.

Simulating a trip duration is supported, custom durations can be specified. Just select Xcode and it gets the route as waypoints.
Of course ios7 prohibits creating fake locations on real device.
For testing purpose there are two approches:
1) while device is connected to xcode, use the simulator and let it play a gpx track.
2) for real world testing, not connected to simu, one possibility is that your app, has a special modus built in, where you set it to "playback" mode. In that mode the app has to create the locations itself, using a timer of 1s, and creating a new CLLocation object.
3) A third possibility is described here: https://blackpixel.com/writing/2013/05/simulating-locations-with-xcode.html
Create a .GPX file with xcode, then specify your coordinates and when your device connected, hit the little arrow button and select your .GPX file. You can create multiple files and add lots of coordinates to single .GPX file in order to make some kind of route.
When running in debug mode you can use the little arrow button in the debug area (Shift+Cmd+Y) in Xcode to specify a location. There are some presets or you can also add a GPX file.
You can generate GPX files here manually: http://www.bikehike.co.uk/mapview.php (from answer: https://stackoverflow.com/a/17478860/881197)
