How does appcode launch an application in debug mode

Hello,
I'm interested in the technical details of how appcode launches an application on the device connected via USB.

This SO question

http://stackoverflow.com/questions/6172688/how-does-jetbrains-appcode-launch-the-ios-simulator

seems to indicate that it is possible via MobileDevice.framework. However studying the functions described at:

http://theiphonewiki.com/wiki/index.php?title=MobileDevice_Library

I can't find a function that looks like it actually launches an application.

Can the Jetbrains team share technical details?
