Swift Decision Making

Sometimes in a program we need to test a condition. If condition is true we perform first action and if condition is false we perform second action.

Now what does that mean?

1) Simple if Statement

if statement is used to test a given condition. If given condition is satisfied then only block inside if statement will gets executed.

Example :-

  import UIKit

var a:Int = 10

if(a == 10)
{
 print("a = (a)")
}

Output :-

a = 10

In this swift program we first initialised a variable "a" with value "10" . Then if condition checks wether 'a == 10' or not . Since value matches block inside if is executed. That's why output 'a = 10' .
