optional_01.swift

Person {
  var firstname: String
  var middlename: String
  var lastname: String
}

//this will definitely work because i have a middlename
let me = Person(firstname: "Abel", middlename: "abel", lastname: "Adeyemi")

//This will throw an error
let anotherPerson = Person(firstname: "Abel", middlename: nil, lastname: "Adeyemi")

I'm getting error executing the same code. Please let me know the solution

What’s the error message

You should have it in a Struct or Class.

import UIKit;

struct Person {
  var firstname: String
  var middlename: String? //we created the optional with the ?
  var lastname: String
  
  func fullName() -> () {
     print("Your fullname is \(firstname) \(middlename!) \(lastname)")
  }
}

let me = Person(firstname: "Abel", middlename: "Agoi", lastname: "Adeyemi");

me.fullName();

Thankyou

It shows me error if I use the class . Send me code using class keyword.
