[Help!] Unsure of correct syntax for this simple method

Task: 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

This should be really doable, I just can't seem to figure out the correct syntax after fumbling around. Please help!

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

    var fullName = (firstName  lastName)
    func getFullName() {

    return fullName

    }

}

Sheng Wei Pang, the function is inside the struct so it has access to the firstName and lastName member variables. So all you need do, in the function, is return those values in a String, using String interpolation. (Concatenation may also work, I didn't try that.)

struct Person {
    let firstName: String
    let lastName: String

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

let aPerson = Person(firstName: "Wei Pang", lastName: "Sheng")
let fullName = aPerson.getFullName()

Then, you create a Person object, aPerson, and pass in a first and last name. These are stored in the object's member variables, so when you call the getFullName() function on that object you get the full name back.
