CodePiece.swift
let hexString = "0123456789abcdefABCDEF"
let even = hexString.characters.enumerated().filter { $0.offset % 2 == 0 }.map { $0.element }
let odd = hexString.characters.enumerated().filter { $0.offset % 2 == 1 }.map { $0.element }
let bytes = zip(even, odd).flatMap { UInt8(String([$0.0, $0.1]), radix: 16) }
Data(bytes: bytes) as NSData // <01234567 89abcdef abcdef>
