XCode 4 is not a language. XCode is an IDE used to write programs. With XCode you can write for a variety of languages, including C, C++ and Objective C. Objective-C is the language (and really C) are the languages you will need to learn to be able to develop for the iOS and OSX platforms. I say C because Objective-C is a strict superset of C - you can find some good tutorials and books for Objective-C and working with that will get you started, but at some point you will want to become more familiar with C. I say this because there are some libraries that are used in iOS and OSX that are C libraries and not objective C, so it's good to have an understanding of C as well.
