Am I close?

How do i combine the two??

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

    var user {
        return "\(name) \(age)"
    }
}

Hi Tyler,

You are close! For the question, you have accomplished all that is needed, however that variable 'user' that you have inside the protocol is not called for. Also, the age property has both get and set functionality. The answer can be achieved like so:

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

I hope this helps!
