# Swiftly Up to Speed
<!-- (tldr: [pricing and ordering options](#ebook-eofferings)) -->
## The Power of Swift Types (June 2014)
Swift is a new programming language currently in limited release, but
soon millions of Swift programmers will start popping up all around
the world.
Want to get ahead of them?
Swift can help you write better programs. Swift can help you
create better data structures. Swift can help you think more clearly
about unfortunate code corners we all fall into from time to time.
All these new features and capabilities come with a
slight learning curve. Even if you write code in a dozen programming languages
every day, Swift still has some attention grabbing features.
We're starting out by covering Swift's ability to create custom types.
Swift is an early-binding, strongly-typed language, and Swift takes full advantage of those
strong types by letting you create custom types, with full verification at
compile time, to improve the reliability and readability of your code.

## Audience Experience Level
The __Swiftly Up to Speed__ series is written for developers of all ages
and all experience levels.
The __Swiftly Up to Speed__ series follows reliable learning patterns
of introducing concepts, expanding on them, then
using your new concepts in examples and exercises throughout the book. Useful repetition of core concepts really
gets salient points across with as little confusion and frustration
as possible. (All learning involves some confusion and frustration. If you already
knew the topic, you wouldn't have to learn it!)
The __Swiftly Up to Speed__ series is a collection of instructional books
meant to be read from beginning
to end, then even read again to really drive the points home.
These books are
tools to help you learn, understand, practice, and expand your
thinking about modern programming challenges while keeping a focus on reliability
and improving productivity.
If you're looking for just a reference book or a printed
copy of online API documentation, you've come to the wrong place. This
is learning country.
## Format, Layout, Length
__Swiftly Up to Speed: The Power of Swift Types__ introduces you
to Swift's ability to define custom compile-time checked
types to help improve the clarity and reliability of your code.
Each section has plenty of examples included directly from Swift Playground REPL
sessions so you can follow along easily even if you aren't in front of Xcode.
The printed PDF version runs a little
over 50 pages. The iBooks formatted version is about 110 pages. The Kindle version
doesn't report page numbers, but it has lots of "offsets" depending on the size
of your reader.
With zero Swift experience and minimal
experience approaching problems by modeling your own custom types, it will
probably take you an hour or two to just skim the book if you don't
pause to think or work examples and exercises.
You should be operating at Learning Speed, not

Currently Xcode6-Beta is required to use Swift Playgrounds. Even if you don't
have Xcode 6 yet, the Swift Playgrounds will still let you view and edit code.
Swift Playgrounds contain all the code in plain text, so you can still see everything
in one place instead of trying to copy example code from your e-reader back to your desktop for
coding exercises (and good luck trying to copy code samples from your Kindle or iPad into Xcode).
