Usage

Call .enableGameCenter() inside the App struct to authenticate with GameCenter.

import SwiftUI
import GameCenterUI

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
                .enableGameCenter()
        }
    }
}

A view showing the highscore in a button that presets the leaderboard if authenticated. When not authenticated the button will take the user to the preferences where one can log in to GameCenter.

struct MyGameView: View {
    @Binding var highscore: Int

    @Environment(\.gameCenterIsAuthenticated) var gameCenterIsAuthenticated
    @State var showGameCenter = false
    
    var body: some View {
        if gameCenterIsAuthenticated {
            Button("Highscore \(highscore)") {
                showGameCenter.toggle()
            }
            .gameCenter(
                isPresented: $showGameCenter,
                launchOption: .leaderBoardID(
                    id: "SomeLeaderboardID",
                    playerScope: .global,
                    timeScope: .allTime))
        } else {
            Button("Log in to game center") {
                openGameCenterConfiguration()
            }
        }
    }
}
