New book: Understanding Swift

Answers common beginner questions and more

Paul Hudson May 29th 2020 @twostraws

I've just published a new book called Understanding Swift, complementing my 100 Days of Swift and 100 Days of SwiftUI courses by answering the most common questions folks have. Everything I have released for the last 20 months has been available free, and this new book is also free right here: Understanding Swift

This book is different from my others that show you how to build stuff with Swift, because this one is trying to answer many of the "why" questions learners have – why are tuples different from structs? Why do copies of a class share data? Why would you want a failable initializer?

You might look at some of the questions and think they are easy, but every one of them was drawn from questions I've been asked by folks completing the 100 Days of Swift/SwiftUI – this book tries to bring them into one place so folks hit fewer problems and feel more encouraged.

If you'd prefer a download edition of Understanding Swift, you can buy it here. But I want to get this to everyone who needs it, so I'm retroactively adding it to my Swift Power Pack

Last December I launched a Patreon so folks could help support my work, and it's helped keep things afloat. So, Understanding Swift is dedicated to everyone who supports me on Patreon – thanks, folks!

You can find out more about my Patreon here.

PS: If you're following the 100 Days of Swift/SwiftUI, I have added links to Understanding Swift directly to each day so you have optional extra reading if you want it.
