Needing help

I've tried a lot of different ways and still nothing works.

error.swift 
enum BookError: ErrorType {
  case IncorrectTitle
}

func lend() throws { 
 let hello = "world"
 }

You did good with the first task. You are defining your function throws correcty. For the second task they want you to throw that error from inside your function. Your code would look like this.

enum BookError: ErrorType {
  case IncorrectTitle
}

func lend() throws { 
  throw BookError.IncorrectTitle
}
