Getting Started with Swift Compiler Development
Getting Started with Swift Compiler Development August 23, 2017 Over the next few months, I'll be writing a guide to each section of the Swift compiler source code: swift/lib/Driver, swift/lib/Frontend, swift/lib/Parse, and so on. First, here's how I set up a workspace for building and making patches to the Swift compiler. Being able to modify, experiment with, and attach a debugger to my own copy
