Very small e-mail validation helper written in Swift. It contains regular expresion that is compliant with RFC 5322. You can use it via Swift Package Manager or just copy file SwiftEmailValidator.swift into your project - done!

Simple as this:

let result = EmailValidator.isValid(email: "[email protected]")

There is only 1 static function isValid(email:) enclosed in namespace EmailValidator (just a case-less enum to not create any instances of EmailValidator)
