From inside the body of the function, throw an error using the error object and single member provided.

I have looked up the forum and couldn't find any discussion answering the task 2 yet. I am stuck on this one.... I don't know where to start with this question... Thanks in advance :)

error.swift
enum BookError: Error {
  case incorrectTitle
}

func lend() throws {
   throw BookError.incorrectTitle
}

So I figured it out on my own :)

enum BookError: Error {
  case incorrectTitle(description: String) 
}

func lend() throws {
   throw BookError.incorrectTitle(description: "newMember")
}
