Adding Instant Methods Challenge

Not sure what I am doing wrong here. Can somebody give me a clue on this?

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

    func fullName() -> String {
        var result = String()
        let combined = String("\(firstName) \(lastName)")
        result.append(combined)
        return result
    }
}

You have the right idea with the string interpolation to create the full name, but you're trying to do too much with the variables result, combined, and then trying to append that somewhere. It's much simpler than that. You simply return the interpolated full name string. Often times when it seems like something is over complicated it probably is.

struct Person {
  let firstName: String
  let lastName: String

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

The second part of this challenge wants you to create an instance of Person and then use the fullName() method we created on it. As always, creating an instance of something is done much easier in Xcode.

let aPerson = Person(firstName: "Billy", lastName: "Bobby")
let myFullName = aPerson.fullName()

Hopefully this helps you out and happy coding! :smile:
