[Taps] New Transport Networking APIs in iOS 12 beta

[Tommy Pauly <[e-mail]>]

Hello TAPS!

This week we released Network.framework, a new set of transport APIs, as part of the beta for iOS 12 and macOS Mojave.

This API provides support for connections and listeners using TCP, UDP, TLS, and DTLS; connecting by name or service, with happy eyeballs support for addresses, interfaces, and protocols (for proxies, etc). This provides our basis for “post-sockets” API work. As we define as a working group more of the full TAPS API vision for protocol agility, we'd like on add that support to this framework.

If you are an iOS or macOS developer, please try out the APIs! Either way, we’d love for everyone to take a read through the API and give feedback on how we can continue to evolve things towards a post-sockets and fully TAPS model. Note that on iOS and tvOS, this framework is currently using a user-space networking stack instead of sockets when applicable.

Best,
Tommy
