Minimal Example

The smallest possible ManifoldKit app — one call to bootstrap, one view.

import SwiftUI
import ManifoldKit
import ManifoldUI

@main
struct MinimalExampleApp: App {
    @State private var result: QuickStartResult?
    @State private var error: ManifoldKitError?
    @State private var showModelManagement = false

    var body: some Scene {
        WindowGroup {
            if let result {
                NavigationStack {
                    ChatView(showModelManagement: $showModelManagement)
                }
                .environment(result.viewModel)
                .modelContainer(result.bootstrap.modelContainer)
            } else if let error {
                ContentUnavailableView("Failed to start", systemImage: "exclamationmark.triangle", description: Text(error.errorDescription ?? ""))
            } else {
                ProgressView().task {
                    do { result = try await ManifoldKit.quickStart() }
                    catch let e as ManifoldKitError { error = e }
                    catch { self.error = .from(error) }
                }
            }
        }
    }
}

ManifoldKit.quickStart() builds the SwiftData container, registers the compiled-in backends, and wires up a ChatViewModel. On first launch (no persisted sessions) it auto-creates an initial empty session and activates it, so ChatView's composer is enabled the moment the view appears. Errors surface as ManifoldKitError — see MinimalExampleApp.swift for the explicit handling shape.

Running

1. From Example/Examples/, run xcodegen (if you haven't already).
2. Open ManifoldExamples.xcodeproj in Xcode.
3. Pick the MinimalExample scheme and run on Mac or an iOS simulator.

What to look at next

• Sources/ManifoldKit/QuickStart.swift — what quickStart() actually does.
• Example/Advanced/ — the advanced reference app (sessions, model management, custom composer accessories, etc.).
• Drop down to ManifoldBootstrap.build(...) directly if you need a custom inference service, model container, or non-default backend mix.
