I really Recommend the Swift Apprentice
I read the Book and I really recommend it to anyone with cero knowledge on Swift or
a person with gaps in the knowledge and wants a excellent book reference.
This books is the best I have found ever to learn Swift.
In my journey I have read very bad ones with trivial non-sense examples and never-ending cryptic explanations of easy topics like -protocols- making them so confusing of something that is really easy.
I read the Apple The Swift programming language (1.0, 2.0 and 3.0) x3 Times and I never undestood some things until I read the Swift Apprentice.
In this Book I like everything. The style, the examples are very clear and even the jokes were very helpfull pointing me that my anxiety or lost-feeling will find an answer in the coming pages.
Please make more books like this one.
