Wrappers for Swift Concurrency asynchronous actions on controls that enable user interaction specific to each platform and context provided by SwiftUI.

It's based on the following post: https://zenn.dev/treastrain/articles/3effccd39f4056

• ✅ Designed for Swift Concurrency and SwiftUI.
• ✅ Compatible with all Apple platforms (iPhone, iPod touch, iPad, Mac, Apple TV, Apple Watch, Apple Vision Pro).
• ✅ Automatically cancels the task and performs a new action on new user interaction.
• ✅ Automatically cancels the task after the view disappears before the action completes.
• ✅ Supports Sendable and inherits the Actor context.
• ✅ No dependencies.

import AsyncSwiftUI

struct ContentView: View {
    @State private var isRunning = false
    
    var body: some View {
        AsyncButton(isRunning ? "Running..." : "Run") {
            isRunning = true
            defer { isRunning = false }
            do {
                print("START")
                try await Task.sleep(for: .seconds(2))
            } catch {
                print("ERROR:", error)
            }
            print("FINISH")
        }
        .disabled(isRunning)
    }
}

To use this library in a Swift Package Manager project, add the following line to the dependencies in your Package.swift file:

.package(url: "https://github.com/treastrain/AsyncSwiftUI", from: "0.1.0"),

Include "AsyncSwiftUI" as a dependency for your executable target:

.target(name: "<target>", dependencies: [
    .product(name: "AsyncSwiftUI", package: "AsyncSwiftUI"),
]),

Finally, add import AsyncSwiftUI to your source code (or replace the existing import SwiftUI with it).

The documentation comments included in this library, with some exceptions, are from the SwiftUI entry in the Apple Developer Documentation.
