Works but wrong, wrong, wrong

this is one of 20 or so variations that I've tried struct Person { let firstName: String let lastName: String func fullName ( ) -> String { let fullName: String = (firstName + " " + lastName) return fullName }} let person = Person.init(firstName: "Tom", lastName: "Brown") let name = person.fullName()

structs.swift 
struct Person {
    let firstName: String
    let lastName: String
   func fullName ( ) -> String {
        let fullName: String =  (firstName + " " + lastName)
        return fullName
    }}
let person = Person.init(firstName: "Tom", lastName: "Brown")
let name = person.fullName()

You were almost there!

You did not have to have to use an init method there. In a sens, it does work since your are providing initial values to your firstName and lastName. However, in this case it was not asked an init method to be used therefore why it could have raised an error.

Also, you forgot to put an "a" in front of your "aPerson" constant. Which could have been the other source of error.

Here is my solution to this code challenge:

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

}

let aPerson = Person(firstName: "John", lastName: "Doe")

let myFullName = aPerson.fullName()

I hope it helps! :)

Hey Alex Thank Ü but that does not seem to be what they are asking for. The error I get is that I need an instance method named fullName() to the struct definition. It seems like we have that though....

Hmm strange I just tested my code on the challenge it works :/

Make sure you don't have extra spaces between your parentheses and that your constants are properly named.
