Apple's iOS devices (and Windows machines) are not as vulnerable as Macs or devices running Linux or Android because the vulnerability relies on a flaw that allows what's supposed to be a single-use encryption key to be resent and reused more than once, something the iOS operating system does not allow, but there's still a partial vulnerability.
Once patched, devices running iOS, macOS, tvOS, and watchOS will not be able to be exploited using the KRACK method even when connected to a router or access point that is still vulnerable. Still, consumers should watch for firmware updates for all of their devices, including routers.
