Swift ABI Resilience - Lessons for C++ - Meeting C++ 2023

Explore the intricacies of Swift's ABI resilience model in this comprehensive conference talk from Meeting C++ 2023. Delve into the design and evolution of Swift's ABI approach, examining key concepts such as ABI stability, dynamic linking, and resilient type layout. Investigate reabstraction, materialization, and the role of resilience in library evolution. Analyze the potential performance costs and opt-out mechanisms associated with ABI resilience. Compare Swift's approach to C++'s ABI challenges, considering how lessons from Swift might inform future C++ development. Gain insights into the ongoing discussions surrounding ABI stability in C++, including references to wg21.link/P1863. Discover potential solutions to liberate C++ from its ABI conundrum through this in-depth exploration of Swift's innovative approach to ABI design and implementation.
