treastrain/AsyncSwiftUI

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

Features

• ✅ 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.

Samples

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)
    }
}
