I last blog we learnt that how to create Hello World program Using swift.Before to create a Iphone application you have to little knowledge about swift programming,In this blog explain basic programming in swift for IOS development.
No need of any programming knowledge to learn that. 

So lets create playground project to learn all this things.Create a project and after that go on xcode -> file -> playground  Select platform as ios 

save this on same folder of your project(can find it easily)

The editor, will look like that.

So in this blog we will learn about swift variables,array-dictionary..

Variables : In swift we use var keyword to define variables.for example str is variable and it is sort of string..In the right hand site it show the instant result so its good platform to learn

Difference b/w array and dictionary is that array is ordered and dictionary is not.
