Can someone please explain more about get set with protocols?

Hi. I'm a bit confused on setting a get set property in the protocol. Can someone please explain more about it? Thanks

Lana

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

struct Person {
}

get & set decides how a certain property can be used. If a property is getable you can only retrieve the value that the property contains, while if the property is gettable and settable you can retrieve the the value of the property and also manipulate that value. So if you look att your protocol you can see that you can only retrieve the name of the user while you can retrieve and change the age of the user.
