Jim,
When you ship a Swift framework it does not contain source code. But if you want to give someone else the ability to build the framework (say because you don’t support a specific compiler version or specific ABI, or so unneeded parts can be left out), you must ship the source. Some software distributions come in binary form, some come in source form, and some come in both. But a Swift framework is what it is.

Whereas in ObjC, I can give someone the header and the framework, and they can't see the internals, and thus be tempted to program to an implementation (or, for that matter, myself) :)
