Swift Meets C/C++

This gist is a simple example on how to call a function written in swift from C/C++, without taking the detour via Objective-C/C++.

In this example we're going to invoke a function called say_hello, which, as the name already suggests, prints "Hello, World!" to the terminal.

Using WebAssembly in LLVM

Compiling

# locations, e.g.
export WORKDIR=~/llvmwasm; mkdir -p $WORKDIR
export INSTALLDIR=$WORKDIR

Create Codesign Certificate

First we need to create a certificate. The llvm provided a way to do that, but I found this way to work slightly better for me. Just substitute lldb_codesign for the certificate name, instead of gdb-cert.
