What do these Xcode 4 debugger icons mean?

Question

I haven\'t been able to find what these Xcode icons mean. Some you can deduce (cup icon is cocoa, person icon is your code) but other\'s are more mysterious.

Answer 1

Here's a quick screen shot of the folder mentioned. The names explain the meaning of each icon. This is from xcode 5 beta 2.

Answer 2

The icon means, in general, assembly for which you don't have debugging symbols. Not your code (the person icon), not public, top-level Cocoa code (the mug), not Framework/library code (the suitcase) but plain old assembly.

I don't think this is documented anywhere (I haven't seen it) but it seems to hold true for all the tests I've done.
