Object-Oriented Swift : Challenge Task 2 of 2 Help

I am on 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. I have no idea what to do here, can someone help me?

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

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

You're doing great! You've got it all set up properly to make your Person. Now you just need to make them! :smiley:

We do this outside the class definition. Take a look at my solution:

let aPerson = Person(firstName: "Jane", lastName: "Doe")
let fullName = aPerson.getFullName()

So we have a new instance of Person and we're assigning them into the constant aPerson. Then we make a new constant named fullName and assign into it the result of running the getFullName method on this person.

Hope this helps! :sparkles:

Thanks! I was unsure that you had to call the function

I tried this exact solution before finding help

It won't pass and says, " the value being passed assigned to fullName must be the result of calling the instance method getFullName()"

My code runs perfect on playground

Any clues?

Michael Beers I'm not sure what to tell you. If I take this code and copy/paste it into the challenge... it passes both steps:

struct Person {
    let firstName: String
    let lastName: String

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

let aPerson = Person(firstName: "Jane", lastName: "Doe")
let fullName = aPerson.getFullName()

Hope you get it working! :sparkles:

Thanks Jennifer. I got it working! I had String in parentheses after the return arrow. It worked fine in playground. I removed the parentheses and it passed.
