Hi, this is my first post.
I have done Object Oriented Programming with Java and some functional programming with C in the past at University. I’m now looking to learn Objective-C from scratch. I found this website via MacRumours and Amazon and have convinced myself that this is going to be the first Objective-C book that I buy. My question is that I have noticed that the second edition of this book is available for pre-order on Amazon. Is it worth while to pre-order this or would the first edition suffice, I have Mountain Lion installed with the most recent version of xcode installed ?
