The framework directory for Watch OS 2 has CFNetwork framework in it, but instead of header files there is a file called "/WatchOS.platform/Developer/SDKs/WatchOS.sdk/System/Library/Frameworks/CFNetwork.framework/CFNetwork.tbd".
Presumably this is a shorthand method of saying "TBD". Yet this obviously has a dramatic impact on whether something can be ported. Can we get a clearer picture of which APIs there are going to be included?
