iOS Object-Oriented Swift 2.0 Complex Data Structures Adding Instance Methods


Can you pls check my code out? I dont understand the problem here.

struct Person {
    let firstName: String
    let lastName: String
    func getFullName(firstName: String , lastName: String) -> String
    let name: String = "\(firstName) , \(lastName)"
    return name

You are not supposed to put anything into the parameter. Only return the full name by using string interpolation. A return type. Then make a constant called aPerson of instance Person. There you give the Person any first and second name you want. After you can make another constant called fullName (for example) and assign it to aPerson of the getFullName function.

struct Person { let firstName: String let lastName: String

func getFullName() -> String {
    return "\(firstName) \(lastName)"


let aPerson = Person(firstName: "Ewan", lastName: "Rennie")

let fullName = aPerson.getFullName()
