Overview
Swift for the Really Impatient is the perfect jumpstart
to the Swift language for every experienced Objective-C developer.
Leading iOS and OS X developers Matt Henderson and Dave Wood help
you take full advantage of Swift’s powerful innovations,
without wasting time on basics you already know.
Through expert code examples and crystal-clear explanations,
Henderson and Wood reveal how Swift features improve on Objective-C
and show how to make the most of them. You’ll quickly master
“Swift-er” techniques for using objects, classes,
optionals, generics, functions, closures, and more. Each chapter
includes hands-on exercises designed to reinforce and deepen your
skills.
You’ll learn how to re-implement common Objective-C
programming solutions in Swift, improving code clarity, power, and
performance on both desktop and mobile devices. And, because you
probably won’t (or can’t) abandon Objective-C anytime
soon, you’ll discover how to use both languages together,
smoothly integrate Swift into existing projects and workflows, and
gradually move your current code base into the future. Coverage

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.Addison B.
I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.Amir M.
I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
