🚀 BridgeJS is here!
A brand-new JS ↔ Swift bridge just dropped, and it's insanely faster than the existing mechanism!
⚡ Microbenchmarks show it's ~40× faster than the existing mechanism
📦 Import directly from TypeScript type definitions

We are going to take a Swift feature into the browser!
We will set up a WebAssembly app, show how to run and debug it, set up some basic UI, and it will all be powered by Swift’s magical Observation framework.
You absolutely can't miss this!

Huge props to the amazing @swiftwasm project for making this possible! I'm super impressed that the final stripped, optimised, and compressed Wasm file for the playground is only 1.5mb 🤯 And Wasm support has only recently landed in main-branch Swift, it'll only get better!
🎉 carton 1.0.0 with SwiftPM Plugin Support has been released! Now seamlessly integrate with your Swift projects by declaring carton as a dependency in Package.swift.
Details here: github.com/swiftwasm/carton/…
Stdlib and runtime tests for Wasm/WASI now available on Swift CI forums.swift.org/t/stdlib-an…

I just noticed that flowkey, a popular piano lesson app, has officially released a SwiftWasm-based web app!
They said, "We were able to use 100% of our mobile app's business logic for the most essential part of our app" 🥳

It’s time to really get @SwiftLang on server. This made entirely possible by the incredible work from @swiftwasm
When we heard that @andrew_barba is among the first to bring #Swift to the server on our network via @SwiftCloudApp, we sat down to learn more👇

A cross-platform game written in Swift, running in your browser xitter.cf/CarsonKatri/status/154…
I made a word game this weekend with @TokamakUI to test the new layout system. I was able to build the UI just like I would a native SwiftUI app, which was awesome! If you haven’t yet, you should try building something!

- Fix for SwiftPM resources from subdependencies
github.com/swiftwasm/carton/…
JavaScriptKit 0.15.0 is out, which is a major release with new features (BigInt and Symbol support, JS runtime distribution via SwiftPM resources), bugfixes, and breaking changes. Release notes on GitHub as usual: github.com/swiftwasm/JavaScr…
