How to perform a bitwise AND operation in Swift

Overview

In Swift, we can perform a bitwise AND operation using the ampersand & operator. This operator requires two operands. It gets the binary representation of the operands, multiplies them, and returns the result as a decimal.

Syntax

num1 & num2
Syntax for Bitwise AND(&) operation

Parameters

  • num1 and num2: These are the number values on which we want to perform a bitwise AND operation.

Return value

This method returns the decimal equivalent of multiplying the bits of num1 and num2.

Example

Let's look at the code below:

// create some values
var num1 = 3 
var num2 = 2
var num3 = 100
var num4 = 20
var num5 = 1
var num6 = 0
// perform AND operation
print(num1 & num2) // 2
print(num3 & num4) // 4
print(num5 & num6) // 0

Explanation

  • Lines 2 to 7: We create some variables.
  • Lines 10 to 12: We use the AND operator (&) and perform a bitwise AND operation on the values we created. We print the results to the console.
