Finishing up Swift From Two to Three


I’m getting close to wrapping up my latest little self-published Swift book. Like Playground Secrets and Documentation Markup, the book will be available on iTunes and LeanPub. It’s written for anyone who has stayed in Swift 2.3 so they could keep shipping code but who now is looking to move towards Swift 3.

Here are some sample pages to give you a feel for what’s coming up.

As always, if you have any feedback or requests, please let me know. Does this sound like a book you might purchase? I’d love to hear from you.

Thanks again for all the support you give me, my blog, and my books. It’s appreciated beyond measure.


  • Some of us (well at least me) already added parameter labels for methods/functions in 2.2 (and I assume 2.3):

    foo(count count: Int, …)

    What happens to us? You might mention that case

    • You’ve got it.

  • Anything involving UnsafePointer and the like could use some examples.

    • I’ll see what I can fit in

  • Since I don’t care either way, do you have a preference for iTunes or LeanPub?
