The NIO team is thrilled to see the release of Network.framework for Apple platforms! A NIO EventLoop and Channel implementation on top of Network.framework is in testing now and we’ll have an early drop with you very soon. This is great news for NIO users: you’ll be able to use all your existing code without any sockets on iOS and macOS, fully supported.
We also highly recommend you check out our colleagues’ WWDC session introducing Network.framework.
