swift-async-algorithms VS reflex

Last weekend, I started reading up on Swift Concurrency through the use of async-await, actors, etc... I really liked what I read and thought of converting my current code to use these new Swift Concurrency tools and ditch the GCD. I used continuation to convert all methods with completion handlers from the Device class to async throw methods and turned Device into an actor in order to protect some members from race conditions. Once more, I am faced with the issue of calling the async methods of the Device actor one by one (waiting for each ones completion before starting the next one). I spent a lot of time thinking on how to do this and came across a number of useful references such as this one and this one. I tried to think of ways of implementing such a channel in my controller class, to guarantee sequential execution of different tasks that require the underlying library, but I'm facing a few issues with this approach:

AsyncStreams also now has the associated AsyncAlgorithms library https://github.com/apple/swift-async-algorithms which covers a lot of the Combine features (debounce, merge zip etc.)

You might find the treasure trove known as Swift Async Algorithms and look at their test suite.

https://github.com/apple/swift-async-algorithms

Requires Xcode 14, which is still in beta and cannot push to the App Store.

Also, Apple fucked their back port badly. It’s supposedly fixed now, but if you built an app that used async/await anywhere in Xcode 13.X and a user installed running iOS 12/13/up to 14.5 they’d crash on launch.

So I personally wouldn’t trust it, and instead just push to raise your iOS minimum. I’ve had no problems requiring iOS15 in my projects over 1M installs

Asynchronicity is only one aspect of Functional Reactive Programming. You’re comparing single values vs. multiple values. AsyncStream is a better analog, but I’m pretty sure you still need to bring in swift-async-algorithms to have an apples-to-apples comparison.

There's other people around here who would like to know your opinion about these GUI frameworks! I haven't written a GUI in Rust personally, but my favorite GUI framework is not at all OOP: https://reflex-frp.org/

Not to be confused with Reflex, allowing web apps in pure Haskell: https://reflex-frp.org/

FRP solutions sound very attractive. But reflex seems to be stuck on the outdated GHCJS, and I haven't been able to get it to build. The newer JS output in GHC doesn't yet have DOM support. And even if I used one of those, figuring out how to interact with a LaTeX renderer might be tricky.

I only have experience using Reflex, which I regard as the main contender for FRP UI libraries in the Haskell sphere. It's got a flashy website, but I think the documentation is a bit disorganized -- it took a long time for me to figure out how to get going with the library (you find some pieces of knowledge scattered here and there, if you look hard enough). My plan was to learn it well enough to onboard other people, but I don't think I could convince anyone who hasn't already decided that they're gonna make UIs in Haskell no matter the required effort.

Once someone has spent a bunch of time with Haskell and sees the value, they will find Nix if it makes sense. Maybe they'll want to play with https://reflex-frp.org, or they'll discover they want a better way to package 3rd-party dependencies, or they start using NixOS and want to nix all the things, etc. etc. Or, maybe they'll never find a use for it, and that's okay.

Reflex natively supports iOS, along with Android, desktop and web. I would recommend it for functional reactive programming in Haskell: https://reflex-frp.org

It's been awhile since I've tried to get into Ubuntu Touch/Linux mobile development in earnest. I'm currently working on an app using the reflex framework that I hope to eventually target Android, iOS, Desktop, and Linux Mobile.

If you're talking about the current Elm approach, I'm not sure. Otherwise, the paper I linked to notes some of the FRP libraries that existed at the time, some of which are still supported today (like reactive-banana), and otherwise I'd suggest looking at reflex, mentioned in the first post in this thread. I don't think it existed at the time the Elm paper came out.
