The last release and blog post are from 2018, is it actually alive?

&gt; Latest Version: 1.0.0 (September 4 2018)

Project that is still alive, amazingly.

The web version of Keynote with it was amazing.

I paid $20 for their interface builder and never got it.

Objective-J is something I entirely forgot existed.

cause there was Coffee Script, also, right?

Reminiscent of the now 18-year-old Cappuccino project <a href="https:&#x2F;&#x2F;www.cappuccino.dev&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.cappuccino.dev&#x2F;</a>

Reminds me of Vapor - Swift, but on a server; <a href="https:&#x2F;&#x2F;www.vapor.codes&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.vapor.codes&#x2F;</a>

Cool, thanks for details and answer! I guess it would be hard to convince JS&#x2F;TS lovers to try Swift but it&#x27;s worth a shot :D

ElementaryUI author here:It is listed in the js framework benchmark (as elementaryui), so you can check where it lands performancewise ATM:

Bundle size still is a weak spot, and proper bundling&#x2F;splitting of wasm modules has to be willed into existence, but I see no blockers for a pretty smooth experience.Honestly, it mostly started as a &quot;I like Swift, can I use it everywhere?&quot; challenge. But there is a real benefit about fully staying in a modern language and tooling environment. Swift, imho, is a very clean and powerful language that fits this space well, might as well build a comfortable way to use it for web projects.

It would be interesting to see any benchmarks &#x2F; comparisons to understand what are the benefits of having Swift in the browser. Is it faster? Easier to maintain? Or is it based more on the sympathy to the programming language in general?But great job anyway!

ElementaryUI author here (so biased):I agree that is a real risk, but imho past behavior suggests that &quot;Apple&quot; Apple and open-source Apple both can exist and it&#x27;s likely going to be just fine.On the plus side: Apple is paying many many real people to progress the language and tooling mostly in the open with solid community work.

you&#x27;re ignoring the economic context. Languages don&#x27;t exist in a vacuum.Apple would never do that, since a lot of free alternatives are always there. Scala and Kotlin are both very close.

New versions of Swift are truly cross-platform. We support iOS, iPadOS, MacOS, HomeOS, VisionOS, WatchOS as well as BodyOS, BrainOS and iThinkOS.To help developers focus on the future, Swift 9 drops support for deprecated platforms such as Linux, Windows and the web.&#x2F;sI&#x27;m actually a Swift developer; it&#x27;s a great language, but I&#x27;m also married to the Apple ecosystem and wouldn&#x27;t choose it outside of it.

I wouldn’t fly so close to Apple if I have the choice. Apple could pivot at any moment - “New versions of Swift start at $99,99” &#x2F;s

sooner or later this was gonna happen. Swift is like Haskell, but nicer and more programmer-friendly.

Bit by bit, we are having our beloved browser plugins back, at least for some of us.

I’m not sure the compiler is to blame there. The extremely flexible type inference means compilers have to do a lot of work.(Examples at <a href="https:&#x2F;&#x2F;www.swiftbysundell.com&#x2F;basics&#x2F;type-inference&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.swiftbysundell.com&#x2F;basics&#x2F;type-inference&#x2F;</a>)

Fun project, an aside; Apple please fix the Swift compiler. It is so slow. It is so very slow.

Their demo is flakey and sometimes fails to hydrate in Firefox latest

Looks a bit like jQuery mixed with jsx and ember or angular

ElementaryUI author here.The honest original motivation was mostly &quot;Swift for websites, can I do it?&quot;. But underneath, I really want to use one capable and modern language (+ ecosystem and tooling) for all my dev needs. That includes having a native, &quot;in-ecosystem&quot; solution for creating web apps of any kind. Somebody&#x27;s gotta build it...I recently wrote a bit about that on the swift.org blog: <a href="https:&#x2F;&#x2F;www.swift.org&#x2F;blog&#x2F;whats-new-in-swift-august-2026&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.swift.org&#x2F;blog&#x2F;whats-new-in-swift-august-2026&#x2F;</a>

Just wait until they rewrite Swift with Rust.

‘cause Swift is great, I guess! And more seriously, probably for a shared logic with an iOS &amp; android app.

This sentiment is sorely missing from the endless Rust re-writes.

Typescript isn’t that good of a language.

We already have Typescript, I don’t see the purpose.
