UML diagram reverse engineered from iOS project [duplicate]

Question

I watched a video with xcode 3, that shows a button "Design" that displays a UML diagram, but I can't find how to do it with xcode 4.

Answer 1

Try Omnigraffle This has templates for UML diagrams.

If you drop an Xcode4 project file onto its dock icon, it will generate a UML diagram from that.

What it doesn't do is generate code from diagrams.
