Blogpost: Calling Haskell from Swift

Hey all,

I’ve published a second blog post on the Haskell-Swift interoperability series.
This post discusses robustly traversing the language boundary to allow calling idiomatic Haskell functions from Swift by serializing arguments and results. It is reasonably straightforward. It builds on top of the previous post which sets up an XCode project with interoperability with Haskell libraries (which was much more difficult).
