A copy of @cayeric's answer written in swift for your convenience.

func getWord(at position: CGPoint, in textView: UITextView) -> String?{
    var point = position

    //eliminate scroll offset
    point.y += textView.contentOffset.y

    //get location in text from textposition at point
    guard let tapPos = textView.closestPosition(to: point) else {
        return nil
    }

    //fetch the word at this position (or nil, if not available)
    guard let wordRange = textView.tokenizer.rangeEnclosingPosition(tapPos, with: .word, inDirection: UITextWritingDirection.rightToLeft.rawValue) else {
        return nil
    }

    return textView.text(in: wordRange)
}
