I am having error where print statement won't work. Please help!

Here is my code:

protocol Printable {

func description() -> String

}

struct User: Printable {

let name: String

let age: Int

let address: String

func description() -> String {

    return "\(name), \(age), \(address)"
}

}

let user = User(name: "Boris", age: 12, address: "Some address")

print.(user.description())

I don't know why, but there's a period between the word print and (user.description()). Try getting rid of that period :)

Good luck!

Hope this helps, Alex
