Hi people! I am really stuck at this part.

func isReal(word: String) -> Bool {
  let checker = UITextChecker()
  let range = NSRange(location: 0, length: word.utf16.count)
  let misspelledRange = checker.rangeOfMisspelledWord(in: word, range: range, startingAt: 0, wrap: false, language: "en")

  return misspelledRange.location == NSNotFound
}

The problem is it always returns true for me, so it basically recognizes all words as real, even ridiculously obviously wrong ones:

For example when word is "wrenched", "wdrnhc" is accepted. The same for "inferred" and "refnd"

I would really appreciate any help! :)

So silly! :S

I was running it on the simulator, tried it on a real device and works as it is supposed to.

Thank you so much @nemecek-filip!

I guess simulator does not have dictionaries to save disk space :-)

Yes, it makes perfect sense ;) Thanks again!
