What do these Xcode 4 debugger icons mean?

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.

UPDATE 1:

I was able to find the icon files under:

.../Xcode.app/Contents/PlugIns/DebuggerFoundation.ideplugin/Contents/Resources

There's a total of 13 different icons and they are all clearly labeled. In the screenshot that I posted we have:

  • Person icon is User
  • Mug icon is AppKit (or UIKit)
  • Briefcase icon is Frameworks
  • Gear icon is System
  • Morse code icon is Foundation
  • Spider web looking icon is Web

Update 2:

A while back I wrote a blog post that's easier to read: http://jlmendezbonini.com/2013/03/27/Xcode-4-debugger-icons.html

Update 3:

Looks like Apple finally documented it in the Process View Display section. Here's a link to the image:

Solution

  • 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.
