OpenConnectivity allows Connectivity to be used with OpenCombine such that users can subscribe to changes in Internet connectivity using Publishers on platforms where the Combine framework is unavailable.

Connectivity is a framework providing a reliable measure of whether Internet connectivity is available. It provides Combine Publishers which allow the subscriber to be notified on changes in Internet connectivity state. Apple's Combine however is unavailable on some platforms notably prior to iOS 13 in which case OpenCombine exists to fill the gap. This package allows you to subscribe to changes in Internet connectivity on platforms where Combine is unavailable by substituting Combine for OpenCombine.
