Learning Swift with iOS 8 tutorials part 1

What is Swift ?

Swift is Apple's latest 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, and flexible.

The Basics:
Swift Providing below data types in his way of syntax. 

Int             : Used for integer type values.
Double      : Used for floating points values.
Float         : Used for floating points values.
Bool          : Used for Boolean values.
String        : Used for Text data values
Array         : Used for collection.
Dictionary  : Used for collection.

Constants and Variables
In Swift, Constants and Variables need to be declared first before using them.

let  x = 10
var y = 0

You can declare multiple constants and variables in a single line using coma as a separator.
let x = 10, y=11,z=0
var  a = 1, b=10, c=3
