haskell-swift

Home to haskell-swift interoperability libraries and tools

• hxs: a build-tool to setup and build an xcode project that links against a Haskell library as explained in the first part of the guide

  • Usage instructions coming soon
  • Currently missing automatically adding as dependencies the to-be haskell-swift Haskell library and swift-haskell Swift package (As these libraries are not yet complete)
  • Preliminary bleeding edge installation instructions:

  # After cloning the repo
  cd haskell-swift/hxs
  cabal install
  # Create a new empty XCode project in a new directory, and run inside it:
  hxs init
  hxs build
  # Open XCode: in `ContentView.swift` and you should be able to
  import NameOfAppHS.MyForeignLib
  # and call hs_factorial
  Text("Factorial: \(hs_factorial(3))")
  

  • As I've said, this is still missing all the @ForeingImportHaskell, $(foreignExportSwift ...) niceties from the libraries that are WIP.

• swift-ffi: a Haskell library with Swift foreign function interface utilities (Template Haskell) for exporting Haskell functions to call from Swift

• haskell-ffi: a Swift package with Haskell foreign function interface utilities (using Swift 5.9 Macros) for importing Haskell functions to call from Swift
