Beginning Xcode

I'm looking for a comparision between this book, "Beginning Xcode" (which I already have) and Fritz Anderson's "Xcode 3 Unleashed" (which I don't have).Maybe it's just me, but I have found "Beginning Xcode" to be difficult to follow and I am searching for another Xcode book that's equal in depth, but significantly easier to follow.=====For example, my challenge today is I have an external framework which is incorporated under "Linked Frameworks" of my main app Project.Currently, if I re-build this external framework, I then have to re-build my main app.What I wish to do is every time I re-build my main app, I want the external framework to be re-built automatically .. in short, 1 step, rather than 2.I have been told that my answer is in "Unleashed"; however, I just can't find it in "Beginning".=====My current challenge notwithstanding, I do see an advantage in that "Unleashed" is based on Xcode 3, versus "Beginning" dating back to Xcode 2 (2006). I also see raves for both books .. but I still welcome any additions *only* because I already have "Beginning" and "Unleashed" may not have sufficient added merit to warrant the $$$.Thanks very, very much in advance.
