I'm primarily a C++ developer these days, and if the C++ interop is actually good then I'm very excited for the future. For app-dev type stuff it really does seem like it's better than Rust, and I can definitely see a world where we start migrating some code into Swift. Edit: back from watching the video, and a few observations: - Swift does not suffer from Rust's refusal to add things into the standard library. gasp regex support in stdlib? Async/await runtimes? - Default testing framework is a godsend, especially when integrated into the build system - Rust but better for everything that's not low-level systems development is the impression I get

The default testing framework made my jaw drop a bit - I have a very hard time seeing Rust have the enthusiasm or momentum to implement something like that right now.

  Why do you think they wouldn't? (I don't keep up with Rust+its community closely enough to know.)

  But Rust has had a default testing framework since 1.0?

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) https://www.youtube.com/watch?v=lgivCGdmFrw https://www.youtube.com/watch?v=lgivCGdmFrw - "Swift as C++ Successor in FoundationDB" (Konrad Malawski; Strange Loop 2023) https://www.youtube.com/watch?v=ZQc9-seU-5k https://www.youtube.com/watch?v=ZQc9-seU-5k And then a series of blog posts by Doug Gregor: - "Swift for C++ Practitioners" https://www.douggregor.net/posts/ https://www.douggregor.net/posts/ And finally: - "Mixing Swift and C++" (Swift.org) https://www.swift.org/documentation/cxx-interop/ https://www.swift.org/documentation/cxx-interop/

Apple is using it for some low-level stuff and they appear to be trying to improve that every year. I think they want to be able to use a limited subset of it in their kernel. Actually I think they already are but I’m not positive. Obviously it started as an application level language but I do think they’re trying to move it down the stack as well.
