Summary: Got a little time on the plane to mess around with this idea. Very much want comments on this! Some questions: - We should probably compile out parts of this using `#if DEBUG`. - Should I compile out all of the description methods? - Maybe I wrap the entire debug files w/ `#if DEBUG ... #endif` so none of it is loaded? - ryanolsonk I used [FLEX](https://github.com/Flipboard/FLEX/blob/master/Classes/Utility/FLEXHeapEnumerator.m) for searching the heap, lmk if you see any problems w/ this - Its lifted w/ only a few changes for my specific needs (including comments 😂) - Chalk us up for using [another bit](https://github.com/Instagram/IGListKit/blob/master/Source/Internal/IGListAdapterProxy.m#L77-L82) of your code - Added a basic test so that the basics of this work and coverage doesn't tank - Anything else I should test? - Is there more data we should be dumping? - I have to track batch update state on the updater in order to dump it. If this seems dan Closes https://github.com/Instagram/IGListKit/pull/617 Reviewed By: jessesquires Differential Revision: D4929426 Pulled By: rnystrom fbshipit-source-id: fcba0d6f0b7766485440f208cf70ad39dfc7a42e
