Hi Davide,

We’ve just released an initial implementation of libSyntax for Swift that will be accessible in a toolchain in the near future.

With it, you’d be able to generate Syntactic nodes on the fly, automatically, from Swift. I’d love for it to be applied to a fuzzer — I wanted to write something like that myself!

I’ll reach out offline and talk to you more about this.
