I would read the part on instances to get a better understanding

https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/ClassesAndStructures.html#//apple_ref/doc/uid/TP40014097-CH13-ID82

struct Person {
    let firstName: String
    let lastName: String

    func fullName() -> String {

    return "\(firstName) \(lastName)"

    }
}

//This is where I created the instance
let aPerson = Person(firstName: "Jeff", lastName: "McDivitt")
let myFullName = aPerson.fullName()
