Before you start

---

You're sixty seconds away from starting to learn, but before you dive in here's the least you need to know…

Who is this for?

This is aimed at people who want to learn Swift quickly. That might be someone who just wants a broad overview, it might be someone who prefers a "just the facts" approach to learning, or someone who can already code in other languages.

What if this is too fast for me?

You should read Hacking with Swift – it has a much slower, more thorough introduction to Swift.

Will this teach me iOS programming?

No. This focuses specifically on the Swift language. If you want to learn iOS development you should read Hacking with Swift.

Do all videos really last sixty seconds or less?

Yes! Even the more advanced ones. YouTube sometimes reports videos as lasting 61 seconds, but if you buy the download edition you can measure for yourself.

Is the download edition the same?

Yes – it contains all the same videos and text, just as PDF, ePub, Kindle, and HTML, so you can read them wherever you want.

Who can I ask if I have questions?

You're welcome to tweet me @twostraws.

Let's go!
