        if (array.count == 3) {
            return YES;

        return NO;

    NSArray *rules = @[REQUIRE_STRING(@"John").notEmpty.with.message(@"Value must not be empty"),
                       REQUIRE_STRING(@"90001").to.matchRegExWithPattern(@"^[0-9][0-9][0-9][0-9][0-9]$").with.message(@"Value must be US zip code format"),
