Special character validation in swift

[thatswiftguy]

Overview

• Write an extension to string, that returns true and false depending upon the presence of special characters.
• Extension should be declared as public
• Methods or properties could be declared as static

Sample

let str1: String = "abcsg$"
str1.haveSpecialChar() // true

let str2: String = "sfasdf"
str2.haveSpecialChar() // false

Code Path

• Sources -> Extended -> Public -> Extension -> String.swift
