Internet of Things (IoT), What is this new concept ?

First let's begin with this simply definition from techopedia :
"The Internet of Things (IoT) is a computing concept that describes a future where everyday physical objects will be connected to the Internet and be able to identify themselves to other devices. The term is closely identified with RFID as the method of communication, although it also may include other sensor technologies, wireless technologies or QR codes." 

Let's have a precise view from IBM : 

"The Internet of Things represents an evolution in which objects are capable of interacting with other objects. Hospitals can monitor and regulate pacemakers long distance, factories can automatically address production line issues and hotels can adjust temperature and lighting according to a guest's preferences, to name just a few examples. Furthermore, as the number of devices connected to the Internet continues to grow exponentially, your organization's ability to send, receive, gather, analyze and respond to events from any connected device increases as well.

IBM solutions can help put the Internet of Things to work for you by giving you the ability to:

• connect millions of objects and millions of events.
• unlock information in systems of record.
• support new systems of interaction with people, mobile devices, sensors, machines and applications.
• optimize business results with local decision making.
• conduct business virtually anywhere and anytime, using almost any device.
• receive and respond to events in near-real time."

Here a book for you to understand what is really the Internet of Things (IoT) and how it works.

SWIFT PROGRAMMING LANGUAGE (FREE DOWNLOAD PDF)

Swift is a new programming language for iOS and OS X apps that builds on the best of C and

Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns

and adds modern features to make programming easier, more flexible, and more fun. Swift’s

clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an

opportunity to reimagine how software development works.

Swift feels familiar to Objective-C developers. It adopts the readability of Objective-C’s named

parameters and the power of Objective-C’s dynamic object model. It provides seamless access

to existing Cocoa frameworks and mix-and-match interoperability with Objective-C code.

Building from this common ground, Swift introduces many new features and unifies the

procedural and object-oriented portions of the language.

Swift is friendly to new programmers. It is the first industrial-quality systems programming

language that is as expressive and enjoyable as a scripting language. It supports playgrounds,

an innovative feature that allows programmers to experiment with Swift code and see the

results immediately, without the overhead of building and running an app.

Swift combines the best in modern language thinking with wisdom from the wider Apple

engineering culture. The compiler is optimized for performance, and the language is optimized

for development, without compromising on either. It’s designed to scale from “hello, world” to

an entire operating system. All this makes Swift a sound future investment for developers and

for Apple.Swift is a fantastic way to write iOS and OS X apps, and will continue to evolve with new

features and capabilities.
