how come this code doesn't pass the test, the struct should satisfy the protocol or am I mistaken?

I am really confused as to why that code doesn't pass. I made age a constant since its a 'get /set'. I am really confused about { get set } and what it means but from what I've read this should work. Where did I make the mistake?

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

struct Person {
    var name: String
    let age: Int
}

let somePerson = Person(name: "nikita", age: 21)

Change age from let to var and your code will pass! The variable age should not be a constant :)

Oh, sorry, you must of course also infer to the UserType. Person is a UserType. Therefor, it must say Person: UserType.
