-<summary><strong>Handling Universal Links in SwiftUI</strong></summary>
-
-To handle universal links in a SwiftUI application, you can use the `onOpenURL`
-modifier provided by SwiftUI. This will allow you to specify an action to
-perform when a URL is opened by your app.
-
-```swift
-// App.swift
-import SwiftUI
-
-@main
-struct MyApp: App {
-    var body: some Scene {
-        WindowGroup {
-            ContentView()
-                .onOpenURL { url in
-                    handleUniversalLink(url: url)
-                }
-        }
-    }
-
-    private func handleUniversalLink(url: URL) {
-        // Handle the incoming universal link URL
-        print("Universal link opened: \(url)")
-
-        // Use the URL to navigate within your app, update state, etc.
-    }

-<summary><strong>Handling Universal Links in a UIViewController-based App</strong></summary>
-
-In an app using UIViewController, handling universal links can be done by
-implementing the application`(_:continue:restorationHandler:)` method in your
-`AppDelegate`. This method gets triggered when a universal link is opened.
-
-```swift
-// AppDelegate.swift
-import UIKit
-
-@UIApplicationMain
-class AppDelegate: UIResponder, UIApplicationDelegate {
-
-    var window: UIWindow?
-
-    func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
-        if userActivity.activityType == NSUserActivityTypeBrowsingWeb,
-           let url = userActivity.webpageURL {
-            handleUniversalLink(url: url)
-            return true
-        }
-        return false
-    }
-
-    private func handleUniversalLink(url: URL) {
-        // Handle the incoming universal link URL
-        print("Universal link opened: \(url)")
-
-        // You can use the URL to navigate within your app or perform relevant actions
-        let rootViewController = window?.rootViewController as? UINavigationController
-
-        // Replace the following content with relevant actions for your app
-        let storyboard = UIStoryboard(name: "Main", bundle: nil)
-        let viewController = storyboard.instantiateViewController(withIdentifier: "DetailViewController")
-        rootViewController?.pushViewController(viewController, animated: true)
-    }
