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

Assigning constants

Assigning the constants is kinda confusing, not sure which is which

Challenge Task 2 of 2

Let's use the struct to create an instance of Person and assign it to a constant named aPerson. Assign any values you want to the first and last name properties.

Once you have an instance, call the instance method and assign the full name to a constant named fullName.

structs.swift
struct Person {
    let firstName: String
    let lastName: String
    func getFullName() -> String {
    return "\(firstName) \(lastName)"
    }
}
let aPerson = Person(firstName: String, lastName: String)
aPerson.fullName()

Sorry - missed that. You need to provide the names:

let aPerson = Person(firstName: "Steve", lastName: "Hunter")

Then you need to assign the returned full name into a constant called fullName:

let aPerson = Person(firstName: "Steve", lastName: "Hunter")
let fullName = aPerson.getFullName()

I didn't run the challenge before - I just saw the method was wrong! I'm clearly in a rush to get to the pub. ;-)

Steve.

I already tried aPerson.fullName() and aPerson.getFullName(). Neither one works. In Playgrounds, it says "Missing argument for parameter 'lastName' in call. Not sure whats going on.

Hi Matt,

The method is getFullName() not just fullName().

Steve.

Now it works! Thanks for help
