I have been trying to find online release notes for xcode 4.2.1 but have failed. I want to know which ios sdk is shipped with xcode 4.2.1. At the moment I am developing on osx 10.6.8 (i.e. snow leopard) and am using xcode 4.2. This ships with ios sdk 5.0.0.
Basically I'm wondering if I need to upgrade to os x 10.7 (lion) so that I can then install xcode 4.2.1 in order to get access to ios sdk 5.0.1. I'll do all this if I can find out if ios sdk 5.0.1 is included with xcode 4.2.1 but as I say this information seems to be difficult to come by.
Any help is much appreciated, Frank
