I copied the code from tohe video to my xcode project:
protocol RandomNumberGenerator {
func random() -> Int
}
extension RandomNumberGenerator {
func random() -> Int {
return Int(arc4random())
}
}
class Generator: RandomNumberGenerator {}
let generator = Generator.random()
however on the last line, I got an error: "Use of instance member 'random' on type 'Self'; did you mean to use a value of type 'Self' instead?"
What does this mean? Did the code depracate, or am I missing something?

let generator = Generator().random()
You create in instance of Generator by
let generator = Generator()
and then you call the function with .random()
Hope it helps.
