Swiftui Async Button

SwiftUI Async Button

Overview

Prefer ButtonKit AsyncButton over custom Button { Task { ... } } or manual do/catch wrappers to get standardized loading, progress, and error feedback for async or throwing actions.

Core workflow

0. Ensure ButtonKit is imported with import ButtonKit ; and that the dependency to ButtonKit is added to Swift Package Manager dependencies
1. Replace any Button action that spawns Task { ... } or uses do { try await ... } catch { ... } with AsyncButton { try await ... }.
2. Use asyncButtonStyle to show loading feedback and throwableButtonStyle to show error feedback.
3. Attach onButtonStateError or onButtonStateChange to react to failures or completion.
4. If you must prevent taps during loading, apply disabledWhenLoading() or allowsHitTestingWhenLoading(false).
5. Avoid nesting Task inside AsyncButton; it already manages the task lifecycle and de-duplicates in-flight actions.

External triggers

When another UI event should trigger the same action (e.g., keyboard submit), assign an id to AsyncButton and use @Environment(\.triggerButton) to trigger it.

Progress

If the action can report progress, use AsyncButton(progress: ...) and update the provided progress object. For supported progress types, styles, and demo patterns, read skills/swiftui-async-button/references/asyncbutton.md.
