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! 👉 pointfree.co/episodes/ep291-…

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!

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" 🥳 app.flowkey.com/ #swiftwasm

It’s time to really get @SwiftLang on server. This made entirely possible by the incredible work from @swiftwasm
Replying to @fastly
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👇 fastly.com/blog/introducing-…

A cross-platform game written in Swift, running in your browser
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! Code: github.com/carson-katri/grid… Game: griddle.buildpassed.com
