Extensions and Protocols Quiz

Hi,

In the quiz of the course is the following questions:

protocol SomeProtocol {
    func someMethod() -> Int
}
extension SomeProtocol {
    func someMethod() -> Int {
        return 1
    }
}
struct SomeStruct: SomeProtocol {
    func someMethod() -> Int {
        return 2
    }
}
let b: SomeProtocol = SomeStruct()
b.someMethod()

What is the output: 1 or 2?

For me the output should be 1. The quiz says it is 2. Is it correct? If yes, why?
