-save-temps just keeps the temporary files from being deleted. They're still put in TMPDIR rather than in the current directory. Maybe that's not the right choice?

@belkadan is it different from clang? I tried to set TMPDIR to a current dir and found there only an object file (main-somehash.o).

Not for a long run, for sure. I just needed to get all the bitcode from a test suite to check my hypothesis.

Anyways, I think the ticket can be closed, even though the behavior is a bit confusing.

Hm, I guess it is different. Swift's -save-temps doesn't bother to dump every phase of compilation, only those between process boundaries. It's mostly for debugging purposes. I would expect it to save the .bc file, though, since we do use that.

Also filed within Apple, so it appears someone else would have preferred the Clang behavior. In that case the sensible Swift "temporaries" are probably a .sil or .sib file and a .ll or .bc file, in addition to the usual temporaries.

@belkadan thanks!
