This check is important because the user could rearrange letters in baseWord, make up their own word, and enter it into the list. We want to prevent that and check each of the words against an actual dictionary. To do that, we can use the UITextChecker class. This class has methods and properties we can use to check whether a word is an actual word in the dictionary, and what’s especially nice is it will work with misspellings and authenticity in Spanish and Italian as well.

 func isWordInDictionary(word: String) -> Bool {
    return UITextChecker().rangeOfMisspelledWord(in: word,
      range: NSRange(location: 0, length:
