/*If you need to trim the extra spaces off the beginning and end of your string, use stringByTrimmingCharactersInSet.*/
var myString = " Let's trim the whitespace "
var newString = myString.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
//Returns "Let's trim the whitespace"
/*You can also easily remove whitespace and new line characters at the same time using this character set:*/
var newString = myString.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())
