How to capitalize all strings in an array?

Question

I have a array of strings, but all the stings are written in upper case letters. Is there a way for me to make all the strings in the array to lower case, (and with capitalisation)

array = ["BOY","GIRL","MAN"]  
// func to convert it to array = ["Boy","Girl","Man"]

Is there a way to do this, without rewriting the content of the array with lower case letters. I have a very long array of strings in upper case letters.

Please don't add an already posted answer into the question. The place for anwsers is in the answers section, not within the question. — Cristik, Jan 06 '16 at 12:16

You can use the map function like this:

let array = ["BOY","GIRL","MAN"]

let capitalizedArray = array.map { $0.capitalizedString}

SWIFT 4:

The property capitalizedString has changed to capitalized.

let array = ["BOY","GIRL","MAN"]

let capitalizedArray = array.map {$0.capitalized}
