Transliterate Chinese between simplified and traditional (the wrong way).

ChineseTransliterator.swift

import UIKit

struct ChineseTransliterator {

  static func transliterate(text: String, sourceView: UIView) {
    let textView = UITextView()
    textView.isHidden = true
    textView.text = text
    textView.selectAll(nil)
    sourceView.addSubview(textView)

    DispatchQueue.main.asyncAfter(deadline: .now()) {
      textView.perform(NSSelectorFromString("_transliterateChinese:"), with: self)
      print(textView.text ?? "")
      textView.removeFromSuperview()
    }
  }
}

// Above was a joke, use the following
let input = "简体中文内容"
let output = input.applyingTransform(
  StringTransform(rawValue: "Simplified-Traditional"),
  reverse: false
) ?? input
