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!

Cool to see how GoodNotes were able to repurpose their Swift code to also bring their app to the web using SwiftWasm. Great article by @pedro_g_s and @tomayac! https://t.co/mQ8veCe8H1 #Swift @swiftwasm

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

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!

@kylnew On the gamedev note, to tease a little bit, we're working on something called WebAPIKit, which among other things will bring type-safe WebGL bindings. The API is not stable yet, but here's a link to our current sample code ported from WebGL 2 Fundamentals https://t.co/NCuBMVMqf7

[SwiftWasm @swiftwasm]

@kylnew That's very much appreciated! We're very glad you're enjoying our project and your sponsorship helps us greatly 🤩
