iOS Object-Oriented Swift Complex Data Structures Adding Instance Methods

Question regarding Challenge Task 1

I don't understand what part of this code is wrong? The method "fullName ()" was created and should technically work.

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

    func fullName(firstName: String, lastName: String) -> String {
      let name = firstName + " " + lastName
      return name
    }
}

let herName = Person(firstName: "lol", lastName: "jack") 
herName.fullName()

You have written a method that needs to be initialized, that’s the first problem. The second one is that you need to address “self” to access the properties from the struct. The method could look like this.

func fullName() -> String {
  return “\(self.firstName) \(self.lastName)
}

I see, thank you!
