Introduction to Swift Programming Language Part -2

         In this section i am going to explain the syntax and some rules of writing the code in swift compare to objective-C. 

         As we already know that the swift remove the some library from the objective-C so before start writing code in swift you need to

         1. Variable Declaration - 

              In case of Objective-C

 

                   NSString *myString = @"Hello Iphone.";

              In case of Swift

 

                   var myString = "Hello Iphone."

2.  Constant Declaration -


      

              In case of Swift

 

                   let kSomeConstant = 40 

let kSomeConstant: Int = 40

      

              In case of Swift

 

                   var colorsArray = ["Blue", "Red", "Green", "Yellow"]

var colorsDictionary = ["PrimaryColor":"Green", "SecondaryColor":"Red"]
