kishikawa katsumiBare-metal Raspberry Pi Pico entirely in Swift, no C code at all. Vector table, boot2, startup code, runtime stubs, all written in Swift using @\section, @\_extern, and @\c.

Swift LanguageYour favorite C library, now with Swift superpowers. 🦸
New post: how to transform C APIs into idiomatic Swift, with enums, automatic reference counting, and argument-labeled methods. Best of all: no header changes needed, thanks to API notes! 🥳 https://www.swift.org/blog/improving-usability-of-c-libraries-in-swift/
Improving the usability of C libraries in Swift
There are many interesting, useful, and fun C libraries in the software ecosystem. While one could go and rewrite these libraries in Swift, usually there is no need, because Swift provides direct interoperability with C. With a little setup, you can directly use existing C libraries from your Swift code.
rain 🌦️Got unreasonably excited about this new, incredibly straightforward count-distinct algorithm. The CVM algorithm is a direct replacement for HyperLogLog, it nerd-sniped Donald Knuth for weeks, *and* it can easily be taught in an entry-level CS course.

🧪Exit testing is new in Swift 6.2! Now it's easy to check whether code exits cleanly, and ensure it prints the expected output to the console. Here's a sssssuper sssssimple sssssample! 🐍 More at https://developer.apple.com/documentation/testing/exit-testing

TIL about the existence of git worktrees. I’d been using stash for so long I’d never considered there was another option.
To give some context as to how ridiculous Apple’s storage pricing is - updating a MacBook Air SSD from 256gb to 1tb costs £400, but purchasing an entire PlayStation 5 which includes a 1tb SSD costs £380. Daylight robbery at its finest.
