xcode iOS simulator launcher I am trying to understand the ios-sim launcher for cordova projects 
https://github.com/phonegap/ios-sim/
The two points I am trying to understand are ...


What is launching the simulator?


Is it being called as a process from the command line 
something like... /path/to/sim -- args?
Is it being invoked as a system library?
something like... include systemLib/magic 
then being called as a function that launches the simulator 

How is the project being "injected/installed" into the simulator?


I have tracked down the answer as far as my understanding of Objective C can take me. ( @ least I believe the answer to my questions is in this function )

https://github.com/phonegap/ios-sim/blob/master/Source/iPhoneSimulator.m#L180

Its job is to launch the Xcode iOS simulator, at least I believe it is. 

The Goal: 
Is to be able to invoke the simulator directly from command line through the shell with out the need for all these projects dependencies and to better understand the process in which Xcode uses to run the simulator.

PLEASE forgive my shorthand notations and very likely incorrect use of terminology, I am an Interpreted soul lost in a binary universe!

As of Xcode 6, you can use the simctl command line tool.  Check out:

xcrun simctl help


If there are any features missing, please file a radar at http://bugreport.apple.com ... this is a supported interface whereas the ios-sim utility was developed by reverse engineering private Xcode frameworks and can easily break between Xcode releases.
