02: SourceKit (Compiling by Default)

13 March 2017

In this episode, we dive into the framework we love to hate to love: SourceKit.

We wrap up with an overview of method dispatch in Swift.

SourceKit on Linux

• Swift core team is fixing compiler crashers faster than they’re filed!
  • Slava Pestov being a driving force behind many of these fixes.
  • @practicalswift is basically Swift compiler fuzzing as-a-service ;)
  • Undoing all of @practicalswift’s hard work
• SourceKit home page
• Process Isolation
• Key contributors to SourceKit:
  • Brian Croom and his many SourceKit PRs to help get it linking and compiling on Linux.
  • Alex Blewitt and his numerous attempts at getting SourceKit compiling by default on Linux.
• SR-1676: Build SourceKit on Linux
• CMake homepage
• swift-corelibs-libdispatch
• Final PR to get SourceKit building on Linux: #5903
