Just a little. The next time I am brought onto an existing project, I will use one of them. For my own code, I generally know how I have built things. I have my own debugging categories to dump view and controller hierarchies.

To make "code visible" as I use an app, I wrote a category that logs -viewDidLoad -viewDidAppear and anything else one wants: https://github.com/mediumbear/LoggingInterceptor Very handy, never ask "what is this controller called again?", just look in the console.
