How to add a "Base SDK" in XCode 4?

Question

I currently use XCode 4.0 with Base SDK 4.3.

I would like to compile my app with an older SDK, for example 4.2, but I don't have this possibility as I have no other choice than SDK 4.3.

Do you know how to add older SDKs than the default Base SDK 4.3 proposed ?

Thanks a lot !

You cannot do that. Xcode versions are released along with iOS SDK's. They are linked together i.e particular Xcode version can compile the code on the specific iOS SDK only (which it come with by default). To compile your code in lower version of SDK, you need to download the lower version of Xcode
