what is the best debug breakpoint for launchscreen

I am having difficulty with launchscreen and would like to debug it so what is the best breakpoint I can use. I am assuming it would be in apple code as there is no view controller code in my app for this screen. In Xcode I select the screen and start assistant which puts me into the apple code UIViewController.h Is the where I should be doing this?
