    class Solution {
        func lengthOfLastWord(_ s: String) -> Int {
            if s.isEmpty {
                return 0
            return s.trimmingCharacters(in: .whitespacesAndNewlines).components(separatedBy: " ").last!.characters.count

    You can break up the return statement if you'd like for readability, but this is pretty simple and straightforward.
