class Camel {
    var humps: Int
    init?(humpCount: Int) {
        guard humpCount <= 2 else { return nil }
        humps = humpCount
    }
}
let horse = Camel(humpCount: 0)

isn't it will return nil?

guard humpCount <= 2 else { return nil }

in this code humpCount will give 0 and return nil. am ı wrong?

for this question(failable initalizers 7) paul wrote Oops – that's not correct. This will result in a constant that holds a Camel?.

It will only return nil if humps is not less than or equal to 2. 0 is less than 2, so it will pass the guard condition and return a valid Camel object.
