How to build against older iOS versions with the latest Xcode downloads?

I think you should always build using the latest SDK and just set the deployment target to the appropriate version. To ensure your app runs correctly, check everything carefully on all versions and besides check the documentation if the APIs you are using have changed / removed / been deprecated in the different versions of the SDK!
