So a quick question: Lets say I have a system which vends me an AsyncStream. I want to listen to that in my ViewModel, map the result and assign it to my state variable. What is the best way to do that? I am currently spinning up a Task, but wondering whether there is a better tool. - ThreadSky

Having it called from SwiftUI task modifier seems like leaking the functionality upwards, ideally the consumer should not care there even us an AsyncStream under the hood.

I think this is fine. You could move the Task creation into the ViewModel if that feels better to you.

(I don’t have much SwiftUI experience though so unsure if there are alternatives…)

I am creating the Task(s) inside the VM init for now. Alternatively I could make the functions async and await them inside the task modifier, but handling that inside the VM seems preferable here, also given there are some additional layers we need between the initial VM and what is used in the View

That makes sense! I like the cancellation behavior of the task modifier. But I like the encapsulation of the internal task too, and you can get cancellation there with deinit. Go with what feels right!
