Render SwiftUI content view as a function of publisher's latest output

SubscriberView.swift

import Combine
import SwiftUI

struct SubscriberView<Publisher: Combine.Publisher, Content: View>: View where Publisher.Failure == Never {
    let publisher: Publishers.Share<Publisher>
    let content: (Publisher.Output?) -> Content

    init(_ publisher: Publisher, @ViewBuilder content: @escaping (Publisher.Output?) -> Content) {
        // Apply `share` in `init` to prevent recreating the subscription from scratch when `latest` is set.
        self.publisher = publisher.share()
        self.content = content
    }

    @State var latest: Publisher.Output? = nil

    var body: some View {
        content(latest)
            .onReceive(publisher.receive(on: RunLoop.main)) { next in
                self.latest = next
            }
    }
}
