Hi ! 
I'm sorry, I should have replied here days ago, in case someone like you would come here.

So I have ask the question here to prime31. His answer was : 
@baz, there is no magic involved. Simply naming the file PostProcessBuildPlayer_Something will most definitely get the script called. 

So I was doing everything nice, but it still didn't work ! 
I forfeit, and tried to do the postProcessing INSIDE Unity, as described in the last link above.
And it worked !


Basically, what I'm doing is opening the Xcode project, reading it and caching it, and then rewrite it line by line, adding or changing lines when special cases happens.

I have append the code here. I know it will look kinda hardcore at first glance, but do copy it in your fav editor, indent it as you want, and iterate through it like 1 or 2 time, and you will understand. In fac it's pretty straighforward. If I have helped anybody then I'm glad 

 

Courage !
