Can someone help me figure out why my code for the code challenge isn't working?

The hint given is that I should make sure I am adding the instance in the struct definition

structs.swift 
struct Person {
    let firstName: String
    let lastName: String


    init(firstName: String lastName:: String) {
        self.firstName = firstName
        self.lastName = lastName
    }

        func fullName(firstName: String, lastName: String) -> Person  {
                var result = Person(firstName, lastName)
      }
  return result
}

Hey,

a struct doesn't need a custom initializer. Also the initializer definition has 2 errors:

  1. Between first name and last name parameters needs to be a comma.
  2. You used two colons behind the lastName parameter

the right way it would look like this

init(firstName: String, lastName: String) {

Next error, you are returning the result outside of the function.

Next error: The function should return a String and not an instance of Person

Next error: The string should be the first name + a space + the last name

Hope that helps, please don't forget to select this as a best answer if it solved your problem.
