SignedIn

The SignedIn component conditionally renders its content only when the user is authenticated. It reads the current sign-in state from ThunderIDState and displays protected UI for signed-in users, while rendering optional fallback content (or nothing) when the user is not authenticated.

SignedIn requires .thunderIDProvider(config:) in its ancestor view hierarchy.

Usage

import SwiftUI
import ThunderIDSwiftUI

struct ContentView: View {
    var body: some View {
        SignedIn {
            Text("You are signed in.")
        }
    }
}

When the user is not signed in, nothing is rendered unless you provide a fallback closure.

Parameters

Parameter	Type	Required	Description
content	@ViewBuilder () -> Content	✅	The view to render when the user is authenticated.
fallback	@ViewBuilder () -> Fallback	❌	The view to render when the user is not authenticated. Defaults to EmptyView.

Providing a Fallback

Show alternative content when the user is not signed in:

SignedIn {
    HomeView()
} fallback: {
    AuthView()
}

Example: Route Between Screens

Use SignedIn and SignedOut together to implement your app's root routing logic:

struct RootView: View {
    @EnvironmentObject var state: ThunderIDState

    var body: some View {
        if !state.isInitialized {
            ProgressView("Loading...")
        } else {
            SignedIn {
                HomeView()
            } fallback: {
                AuthView()
            }
        }
    }
}
