Swift String lastPathComponent

I have an extension of String like this:

extension String {
    var fileURL: URL {
        return URL(fileURLWithPath: self)
    }

    func appendingPathComponent(_ string: String) -> String {
        return fileURL.appendingPathComponent(string).path
    }

    var lastPathComponent:String {
        get {
            return fileURL.lastPathComponent
        }
    }

   var deletingPathExtension: String {
    return fileURL.deletingPathExtension().path
   }
}

Problem is lastPathComponent contains '/' as opposed to NSString counterpart which doesn't contains this. What is an elegant workaround? Didn't find an elegant answer in StackOverflow.

EDIT: Here is the real code that gives me issues:

  filenameField.text = path.lastPathComponent.deletingPathExtension

I fixed it by switching the two routines, i.e.

  filenameField.text = path.deletingPathExtension.lastPathComponent

I'd suggest to use

(str as NSString).lastPathComponent

You won't create new objects in that case.
