Xcode 4.3 was released some days ago, but there's only a version for Lion:

Is Xcode 4.3 compatible with Snow Leopard?
回答1:
It's unlikely that you will get this version of Xcode running on Snow Leopard. Apple like their developers to keep up-to-date with the latest operating systems, so will drop support for the previous OS after a while. I think Lion has been out long enough now that Apple will deprecate support for Snow Leopard.
回答2:
No. You cannot use it on snow leopard because it's minimum requirement is mac os x 10.7.3 or later.
回答3:
No there is not, I am hoping there will be one available soon.
