iOS Protocols in Swift Protocol Basics Conforming to a Protocol

How do I create a computed property for age, since this is a get set variable in the protocol?

I cannot find the right solution for this objective.

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

struct Person: User {
    let name: String

  var age: Int {
    return 


}

let somePerson = Person(name: "Frank")

Here you go:

protocol User {
    var name: String { get }
    var age: Int { get set }
}
struct Person: User {
    var originalAge = 37

    var name: String {
        get {
            return "Brandon"
        }
    }

    var age: Int {
        get {
            return originalAge
        }
        set {
            originalAge = newValue
        }
    }
}

let somePerson = Person(originalAge: 37)

This way below also passes.

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

let somePerson = Person(name: "Brandon", age: 37)
