Getting a string's length in words not in characters? (Swift)

Question

I am trying to retrieve the word count for the text in a UITextView. I can do this already with characters, as in counting the number of letters/spaces, but want the counter to show the number of words instead.

Can't seem to find anything in the documentation, unless it is in there and I don't understand what it is saying.

Can you edit your question to understand what you mean exactly? — Victor Sigler, Nov 17 '15 at 23:51

To get the word count in a string you can split the string with separator " "(space)

let str = "asd asd asd"

print(str.componentsSeparatedByString(" ").count) // Prints: 3

This won't work in some cases. What if the user types "one,two,three"? – rmaddy Nov 17 '15 at 23:59
.... too bad x) I tihnk there is a function to separate with a set of characters. – Arbitur Nov 18 '15 at 00:01

Yes exist, but I'm afraid that this is not enough, this case need an extra work, removing special characters, then matching, etc – Victor Sigler Nov 18 '15 at 00:06

If you only allow letters:

let str = "one,two"
str.componentsSeparatedByCharactersInSet(NSCharacterSet.letterCharacterSet().invertedSet).count

However in full disclosure this would count words with apostrophes as two words.
