I tried to learn SwiftUI a few years ago. XCode was horribly slow, and it would hang and crash all the time, even when working on small example projects. I'm excited by the thought that I can use any rust IDE to write UI code. Rust's compiler, toolchain and IDEs seem way more reliable.

The view! builder macro at the moment is designed to look like JSX, since it was ported directly from leptos. But I'm considering dropping the jsx and using a fluent API. Something like this:

    let count = RwSignal::new(0u32);

    let view = vstack().padding(16.0).gap(12.0)
        .child(label().text(move || format!("Count: {}", count.get())))
        .child(
            hstack().gap(8.0)
                .child(button()
                    .on_click(move |_| count.update(|c| *c = 0))
                    .text("Clear"))
                .child(button()
                    .on_click(move |_| count.update(|c| *c -= 1))
                    .text("-1"))
                .child(button()
                    .on_click(move |_| count.update(|c| *c += 1))
                    .text("+1"))
        );
