21,046 PointsHey Habib Miranda,
Don't over think things! This one is quite simple. As you know for a data type to conform to a protocol, it has to implement all the required methods and properties of that protocol. Normally, you would just conform to the protocol by adding these methods or properties to the definition of the data type directly, however, in this situation we will achieve the conformance by extending the User type.
All you have to do is create an extension of the User struct and list the protocol that it inherits from just as you would do normally and the same way how you would specify a parent class of a subclass.
Then inside the body of that extension is where you write the actual implementation of the requirements defined in the PrettyPrintable protocol. In this case, there is only a single requirement:
We have to create a computed property (read only) that returns a String. The property must be named prettyDescription. The string we return here doesn't matter for the challenge to pass. The purpose was just to achieve protocol conformance.
protocol PrettyPrintable {
var prettyDescription: String { get }
}
struct User {
let name: String
let ID: Int
}
// Enter your code below
extension User: PrettyPrintable {
var prettyDescription: String {
return "This string does not matter for the challenge"
}
}
Good Luck!
