Today is the day I publish my very first book. It is about ReactiveCocoa. A framework that I use in my day-to-day iOS development and enjoy using it immensely!
Feel free to head out to the book's landing page on LeanPub and be sure to have a look at free chapters of the book. Hopefully they will convince you that this book is written in an approachable manner.
I have to confess though. It's been a while since I sat down to write at least a couple of hundred words for the book. I decided to stop postponing the writing process and publish the unfinished copy. Right now I am putting up a plan including weekly updates on how to finish the book.
And I can guarantee you that everyone who buys the book will receive an update for ReactiveSwift 2 and ReactiveCocoa 6 that are due to release some time in spring along with Swift 3.1.
