[swift-corelibs-dev] Cannot call CFStreamCreatePairWithSocket on Linux

[Tony Parker]

Hi Bouke,

There is currently no plan to open source the more modern versions of CFNetwork. We’ll have to replace its functionality in swift-corelibs-foundation.

It could be technically reasonable to port the open source (very old) CFNetwork to linux. However I am fairly certain that would take a bit of work to get up and running; especially the Security framework portions.
