The sample code is available (for the most part) in Objective-C and Swift thanks to one contributor who translated everything. So it might also be an interesting approach to start with basic concepts in Objective-C but then have a look how the same code translates to Swift.
This book is focussing on Objective-C because 15 months ago, when I started with it, there was no Swift. (see my making of: http://www.cocoanetics.com/2015/01/book-out/)
We might be switching to Swift in a future new edition, but that depends of how much of a commercial success the book turns out to be.

I am really new to ios - started with some tutorials and learning objective c. Is it good choice, or i should switch to swift instead? What do you think about swift?
I see that your book has objective c examples
I am also a new to ios. I had a similar question since apple announced the swift one weeks after I got my hands on iOS.
I decided to stay on Objective-C. My rational was that 1) There are tons of objective-C code that are already written and someone has to maintain it. 2)It will take some time for swift to be the mainstream iOS development language 3) There were tons of more quality educational resources in objective-C than swift.
Things have changed so much since then. So some of my points are not much valid anymore or not as convincing as when I made my mind but I believe they still have some merits now. Of course, YMMV so you need to consider everything based on your situation.... But, whatever the path you choose to take, good luck with your journey on iOS!
