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

The same solution by '@Leo Dabus' but without slices: (Swift 4.x)

    let fullName = "Williams Diaz Robert"
    let words = fullName.components(separatedBy: " ")
    if(words.count < 2) {
        return
    }
    let fistName = String(words.last ?? "") //Robert
    let lastNameArray = words.prefix(words.count - 1)   //["Williams","Diaz"]: [String]
    let lastName = lastNameArray.joined(separator: " ") // "Williams Diaz"
