PunycodeSwift is a pure Swift library to allows you to encode and decode punycoded strings by using String extension.
Punycode is a representation of Unicode with the limited ASCII character subset used for Internet host names. Using Punycode, host names containing Unicode characters are transcoded to a subset of ASCII consisting of letters, digits, and hyphen, which is called the Letter-Digit-Hyphen (LDH) subset. For example, München (German name for Munich) is encoded as Mnchen-3ya. (Wikipedia)

To integrate Punycode into your project, add the following to your Podfile.
platform :ios, '9.3'
use_frameworks!
pod 'Punycode' # Latest (Swift 5.0)
pod 'Punycode', '~> 2.0' # Swift 5.0
pod 'Punycode', '~> 1.0' # Swift 4.2Encode and decode IDNA:
import Punycode
var sushi: String = "寿司"
sushi = sushi.idnaEncoded!
print(sushi) // xn--sprr0q
sushi = sushi.idnaDecoded!
print(sushi) // "寿司"
Encode and decode Punycode directly:
import Punycode
var sushi: String = "寿司"
sushi = sushi.punycodeEncoded!
print(sushi) // sprr0q
sushi = sushi.punycodeDecoded!
print(sushi) // "寿司"
