ABI stability can be quickly understood from a high level when explained as ‘You’ll be able to run code written for older versions of Swift on new versions of it’s compiler.’ Developers get this benefit as they’ve experienced the pain of not being able to do this for several years. This talk will go into how ABI stability is part of the maturing process of any compiled language and how Swift’s story… both it’s origins and progression are sourced in the LLVM and how ABI stability fits into that broader picture.
Three sections of talk:
- Review the origins of Swift and how it’s creation was really sourced in Apple’s adoption of and advancements to the LLVM.
- What drove this for Apple and what you can observe today.
- How the LLVM’s dynamism is enabling performance gains throughout the compilation chain.
- This is the reason ABI stability hasn’t been reached.
- Implications to the compile chain when it has.
- What's after ABI stability for Apple, it's hardware and iOS/macOS.
