macOS Newbie Question on Xcode

[theagentx]

I was seeing a screen shot of a Mac programmer on the web and it looked like he had a flowchart or something in the background that looked like program code,etc in it. What is that tool and what is it used for? I looked in my books and did not see anything referring to it. Just a newbie question...it feels like I am missing out on something here.

I don't think XCode has any modeling tools like this built-in. I'm guessing the user in the screenshot was using some sort of UML/diagramming tool, like:
http://www.apple.com/downloads/macosx/development_tools/visualparadigmforumlenterpriseedition.html
or
http://www.omnigroup.com/applications/OmniGraffle/
or

If you can post a screen capture of a frame with the tool in use, someone here might be able to readily identify it.

That's the XCode Data/Class Modeller as described here

Wow, good times. This demonstrates how little I actually use XCode. =)

That can actually help me map out the apps I want to work on Is there a guide on how to use that tool on the ADC?

See, I am learning on my own now with suggestions from the group

I actually think use fo a tool like this can help newbs possibly? Most of us have trouble mapping the application and get caught up in the flow of things.

Open XCode
Go Help->Documentation
Choose the Developer Tools Library in the source list
Search for class model
Click on the top search result (should be "Class and Data Modeling")

You will now have a page with links to the documents for how to use both the class and data modeller.

Do you use textmate?

No... I just don't program that much Cocoa, and certainly nothing complex enough that there'd be more than a few nodes in the modeler anyway. Mostly if I'm writing Objective-C or Cocoa it's to help someone on these boards. Otherwise, if I'm programming C, C++, fortran, some small python example, etc. I'll do it in vim. If i'm writing Java, if it's just a small, toy program I'll write it in vim. Otherwise I'll use an IDE like Eclipse.

I'm sure if i wrote larger cocoa projects i would spend a lot more time in XCode, and I may have come across the modeler before.

You probably wouldn't run across the modeler unless you're using Core Data. Although it could be useful for modeling your app's entities and relationships even if you're not.
