Checking if the user’s entered word is possible

Looking for duplicate words is not enough. Now that we have generated a random seven-letter word, we want to make sure that the user’s entered word can be made from the letters that are in the random word. For example, if the random word is bookend and the user types in books, that would be invalid because s is not in the random word.

Let’s go back to the DataModel class and add code to the isWordFoundInBaseWord function so that we can check that the word can be made from baseWord:

  //check to see if the word is possible given the baseWord 
    letters
   func isWordFoundInBaseWord(userGuessWord: String) -> 
     Bool {
        var comparisonWord = baseWord
        return userGuessWord.allSatisfy { letter in
        ...
