Based on your code samples and the inspiration from React's Suspense, here's a simple README.md for your swiftui-suspense library:

---

SwiftUI-Suspense

swiftui-suspense is a Swift library inspired by React's Suspense, designed to streamline asynchronous data fetching and component rendering in SwiftUI applications. It introduces a new way to handle asynchronous operations within your SwiftUI views, making your code cleaner and more readable.

Features

• Suspense Handling: Easily manage async tasks with the Suspense view wrapper.
• Fallback Support: Provide a fallback view to display while waiting for async tasks to complete.
• Component Reusability: Simplify your view hierarchy by encapsulating async logic within reusable components.
• Error Handling: With the newly implemented ErrorBoundary, SwiftUI Suspense now provides a way to catch and handle errors gracefully within your views.

Installation

To add swiftui-suspense to your SwiftUI project, simply add the following dependency to your Package.swift file:

dependencies: [
    .package(url: "https://github.com/horita-yuya/swiftui-suspense.git", from: "3.1.0")
]

Usage

Basic Usage

Wrap your view components that require asynchronous data fetching with Suspense, and provide a fallback view to display while the data is loading.

To resolve passed optional argument, use use function defined in Suspense module.

import Suspense
import SwiftUI

struct ComponentA: View {
    var name: String

    init(name: String?) throws {
        self.name = try use(name) {
            try await Task.sleep(nanoseconds: 2_000_000_000)

            return "My name is Suspense!"
        }
    }

    var body: some View {
        Text("\(name)")
    }
}


struct ContentView: View {
    var body: some View {
        VStack {
            Suspense { name in
                try ComponentA(name: name)
            }
        }
    }
}
