Further to this question:

Make UML with the code in xcode4

I wrote some code with Xcode 4. The UML modelling feature in Xcode 3 was removed in Xcode 4.

I would still like to use the UML modelling feature in Xcode 3, will my project written with Xcode 4 work in Xcode 3,

I don't know about your diagrams, but your Xcode 4 project will (mostly) work with Xcode 3. (At least, it ought to work well enough to generate diagrams based on the classes.)

If you’d like to continue using Xcode 4 for development and you have access to another computer or a VMWare image, you could install a copy of Xcode 3 on it and use it to generate diagrams only.

Alternatively, you get a commercial product like Visual Paradigm to reverse engineer your Objective-C source code or start using Xcode 3 again for development (if possible).
