I've found that if I tell Xcode to open Foo.h, and Xcode gets stuck generating a nonexistent interface like that, opening Foo.h *again* while looking at the empty "Generating Interface…" or "No editor" pane will cause Xcode to actually open Foo.h.

I haven't found a universal way to discover how a given API is mapped into Swift except by getting Xcode's code-completion to suggest names for me. It is pretty terrible.
In some cases you can find a proposal for the API on swift-evolution and use it as documentation:
https://github.com/apple/swift-evolution/blob/master/proposals/0088-libdispatch-for-swift3.md <https://github.com/apple/swift-evolution/blob/master/proposals/0088-libdispatch-for-swift3.md>
