As of June 6, 2017, the issues detailed in this post have been resolved. I'm happy with the resolution and encourage anyone interested in React Native development to purchase my book!
It has come to my attention that both the print and PDF versions of React Native By Example are not fit for publication. The indentation of code blocks in the first six chapters are simply not right, being pushed far to the left without any regards for spacing. I am incredibly disappointed by these problems, as they are in direct conflict with the version that I personally approved with my publisher. I have been trying to work with them for the past two months to get it resolved. Unfortunately, those efforts have not been met with any results. My publisher has been wholly incompetent in fixing this issue, having failed twice to resolve them properly. Until the indentation on the book has been fixed, I cannot recommend purchasing a print or PDF copy of it.
