Are there any docs on SKIE Flows in SwiftUI feature that show what is the recommended way to trigger the equivalent of a Compose side effect?

For the example in the docs on the website:

struct ExampleView: View {
    let viewModel = SharedViewModel()

    var body: some View {
        // Observing multiple flows with attached initial values, only requiring a single view closure for content.
        Observing(viewModel.counter.withInitialValue(0), viewModel.toggle) { counter, toggle in
            Text("Counter: \(counter), Toggle: \(toggle)")
        }
    }
}

What is the recommended way to trigger a function (i.e. navigation) when the counter reaches 100 for example ?

That looks more like a SwiftUI question. I think you could use the .task(id) {} modifier in SwiftUI which starts a task when the id changes. It's very similar to LaunchedEffect in Compose

Should we be using SwiftUI's onChange maybe ?

[Filip Wiesner]

Yeah, onChange looks good as well

Thanks, just wanted to confirm that SwiftUI's built in tools will work correctly with SKIE's Flow transformation etc

I have never used it, to be honest, but it's just a normal SwiftUI, so I don't see a reason why it wouldn't work.
