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

My code's correct but its not being accepted. It works in Xcode. Maybe I have the right solution for the wrong question?

Bummer! The value being assigned to fullName must be a result of calling the instance method getFullName()

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

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

let aPerson = Person(firstName: "Mazen", lastName: "Wasel")
let fullName = aPerson.getFullName()

Hi Mazel, you're code looks good and it runs in my complier. Try refreshing your browser. Also to make it easier to write, inside the method, their is no need to declare a constant named fullName you can achieve the same result with just coding return "\(firstName) \(lastName)"

Should look like this, but either way is correct.

struct Person {
    let firstName: String
    let lastName: String

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

let aPerson = Person(firstName: "Mazen", lastName: "Wasel")
let fullName = aPerson.getFullName()

struct Person {
    let firstName: String
    let lastName: String

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

    }
}

let aPerson = Person(firstName: "Mazen", lastName: "Wasel")
let fullName = aPerson.getFullName()

Your code does compile in XCode, but some of the challenges are a little picky about the exact approach. This should get you passing.

Thank you Brian.

It seems that the problem was the brackets around String...

it did not accept the following: func getFullName() -> (String) {

but it accepted the following: func getFullName() -> String {

Does anyone know if the brackets are correct or incorrect syntax? or are they necessary at all or only in some cases?

Not necessary unless you are returning a tuple
