I recently purchased your Pro Swift book, and to be honest this is by far the BEST resource available on the internet for Swift Developers. The way that the author breaks down the concepts into easily consumable chapters makes the book a quick and extremely resourceful read. Additionally one of the best parts about reading the book is that when you dont understand something you can watch a video, which really help cement in the knowledge and fill in the missing gaps.
Thanks again for helping the development community and others! Your resources and this book Swift Pro is by far the best book I have read on the language.
Look forward to reading more!
