Build it for use inside swift project

[stellanhaglund]

Hi I'm trying to run this as part of a swift project. I have added this aubio = {version = "0.2.1", features = ["builtin", "bindgen"]}

But I get errors like this

linking with `cc` failed: exit status: 1
library not found for -lSystem
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any idea what I'm doing wrong?

I haven't any MacOS/iOS machines and I doesn't quite familiar with apple's platform libraries. Maybe some libraries paths is missing.
