In iOS 9 Apple has introduced a number of new shiny things for UIKit Dynamics. One of them is UIFieldBehavior which describes magnetic, electrical and spring fields of influence. Fields are hard to debug (even in real life!) so Apple decided to provide a debug mode on UIDynamicAnimator. The trick is the debug mode isn't published in the headers. Why? Who knows. They mentioned it quite plainly at WWDC 2015 and said you have to turn it on in the LLDB debugger.
