Xcode 4 Preview

Has anyone successfully compiled a script and connected interface objects using the new Xcode 4 Preview?

I can’t seem to find the download link, but this seems to be AMAZING. THE INTERFACE TOOLS ARE BUILT IN! NO HEADER FILE WORK! :o
I do only have a free account, so that might be it. Can someone help me find the download link, or is it only to paying subscribers?

No. From the release notes, under the heading “Functionality No Longer Supported in Xcode”:

I don’t really know where that leaves us…

It only supports:

Well it supports, as in compiles and runs, ASObjC projects OK – it just doesn’t support compiling them without running.
