function that can throw. Name this function lend. It takes no parameters and has no return type.

It says make sure i'm "making a function that can throw"

error.swift 
enum BookError: ErrorType {
  case IncorrectTitle
}

func lend() throws -> BookError {

  }

Hello:

You are close, but the challenge does tell you that it has no return type, so just delete the return type you have on yours.

func lend() throws{
}

Remember the arrow specifies the return type, in this case we are not returning anything, so you don't have to add any returns. If you were to return a string then you would add -> String.

Hope this helps.. good luck
