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

Adding an Instance Method

I'm attempting to solve Challenge Task One in Lesson 4 of Object Oriented Swift 2.0. I'm using the following code to combine the first and last names. The code appears to be working fine in my Playground, but I keep being told that there is an error.

struct Person { let firstName: String let lastName: String

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

}

Any thoughts what I'm missing?

You do not need to specify the inputs to the func as it is already being referenced to the struct. For example: struct Person { let firstName: String let lastName: String

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

} let aPerson = Person(firstName:"abc",lastName:"cde") let fullName = aPerson.getFullName()

Hi there,

I don't know if you solved this but this worked for me: ''' struct Person { let firstName: String let lastName: String

func getFullName() -> String {

    let fullName = "\(firstName) \(lastName)"

    return fullName
}

} '''

This is the correct code which is working for Treehouse Code Challenge!!

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

I'm using Xcode Version 8.2.1 (8C1002) and the following is "not compiling" in TreeHouse!

struct Person {
    let firstName: String
    let lastName: String

    func fullName() -> String {

        let name = "\(firstName) \(lastName)"
        return (name)

    }

}

let aPerson = Person.init(firstName: "Master", lastName: "Bates")


let myFullName = aPerson


myFullName.fullName()

Thank you for your help. I see how I can shorten the code in the example I gave. Unfortunately, I am still uncertain why the code is not working in their Code Challenge! Here is the Code Challenge in it's entirety.

"Challenge Task 1 of 2 (Complex Data Structures - Adding Instance Methods)

Given the struct below in the editor, we want to add a method that returns the person’s full name. Declare a method named getFullName() that returns a string containing the person’s full name. Note: Make sure to allow for a space between the first and last name"

struct Person { let firstName: String let lastName: String

}

Here is my response (which works in my Playground, but not in their challenge)

struct Person { let firstName: String let lastName: String

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

}
