How to create a hexadecimal value in Swift with 0x

Overview

A hexadecimal value is a value in the number system that is base 16. By default, all values are in the decimal base, that is base 10. In Swift, we create a hexadecimal value by placing 0x before the digits, we want.

Syntax

Example

// create variables with hexadecimal values
let hex1 = 0x1;
let hex2 = 0xc3;
let hex3 = 0x14;
let hex4 = 0xAC2;
// print the decimal equivalents
print(hex1)
print(hex2)
