iOS Protocols in Swift Protocol Basics Conforming to a Protocol

I am not sure what I am supposed to do to make it settable? Is the rest of my code generally correct though? Thank you

See Above Please

protocols.swift
protocol User {
  var name: String { get }
  var age: Int { get set }
}

struct Person: User {
  let name: String
  let age: Int
}
// What Do I do for making it settable?

let somePerson = Person(name: "Richard", age: 27)

You cannot have constants in your structure; these need to be var :)

protocol User {
  var name: String { get }
  var age: Int { get set }
}

struct Person: User {

  var name: String
  var age: Int
}

let somePerson = Person(name: "Jeff", age: 34)
