Status
The current ANTLR beta release includes a working Xcode plugin, so you can automatically generate your grammars from within Xcode.
It automatically tracks all the dependencies between the different grammars in your project to build them in the right order.
Common error messages and warnings are picked up for display in Xcode using the new -message-format gnu option in ANTLR.
There remain some errors and warnings which cannot be picked up yet, due to missing information in ANTLR itself, but this will change in the future.
Debugging support for use with ANTLRWorks is done, except for exceptions 
I just haven't got around to do it yet. The socket handling code isn't error proof yet, I will add more thorough error handling for the final version. Other than that it works beautifully!
