    In Memory safety is necessary, not sufficient

  • I'm not a (direct) user of the C++ interop, but everything I've heard about it has been quite positive. A few hopefully relevant resources, first a couple of videos: - "Introducing a Memory-Safe Successor Language in Large C++ Code Bases" (John McCall; CppNow 2023) [LINK] …

    In Swift Static Linux SDK

  • Honestly, Swift seems like such a nice language. Most of the performance and power, great interop, but more directed at application development than Rust (with e.g. refcounting being the default). But as they say, you choose a language for its ecosystem, not for the language …
