Swift

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

When the above code is compiled and executed, it produces the following result: Value of varC Hello G 63
