This is the Rough Cut version of the printed book.

Writing networking code has never been easy,
but in an era where practically every app is a connected app, these
skills are absolutely essential. Apple's networking libraries for
iOS and OS X offer complete facilities for creating code to network
with websites, databases, and even other devices running your app.
Often, however, Apple's documentation doesn't cover the details,
subtleties, and scenarios you need to know about.

¿

In Network Programming with Swift,
expert network programmer Karl G. Kowalski brings together all the
knowledge and code recipes you need to create network-ready apps
for iOS or OS X. Kowalski covers crucial issues and new
technologies other Apple network programming ignore, especially
Apple's valuable new Bluetooth LE support. Wherever network
communications requires both a transmitter and a receiver -- as for
a Bluetooth contact-sharing app that transmits specific data and
expects a custom response -- he walks through implementing both
sides. You'll also find expert coverage of data privacy and
integrity issues, third-party libraries and tools, and debugging
network code.

Kowalski presents most examples in Swift,
supporting your migration to Apple's powerful and efficient new
language. Wherever necessary for clarity or other reasons, he also
provides Objective-C examples. Every example is targeted at iOS 8
and reflects the new Xcode 6 development environment.
