println("Value of char1 \(char1)")

println("Value of char2 \(char2)")

Accessing Characters from Strings

As explained while discussing Swift's Strings, String represents a collection of Character
values in a specified order. So we can access individual characters from the given String
by iterating over that string with a for-in loop:

import Cocoa

for ch in "Hello" {

println(ch)

}

When the above code is compiled and executed, it produces the following result:

H

e

l

l

o

Concatenating Strings with Characters

The following example demonstrates how a Swift's Character can be concatenated with
Swift's String.

import Cocoa

var varA:String = "Hello "

let varB:Character = "G"

varA.append( varB )

println("Value of varC = \(varA)")

When the above code is compiled and executed, it produces the following result:

Value of varC Hello G
