3,216 PointsHow 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.
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")

iOS Development with Swift Techdegree Graduate 30,149 PointsHere 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)
