Extract Last Word in String with Swift

Question

What is the way of extracting last word in a String in Swift? So if I have \"Lorem ipsum dolor sit amet\", return \"amet\". What is the most efficient way of doing this?

Answer 1

I would also consider using componentsSeparatedByCharactersInSet, and using the whitespace character set:

let string = "Lorem ipsum dolor sit amet"
let stringArray = string.componentsSeparatedByCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())
print(stringArray.last)
