We’re building a PDF share extension. The app is launched, but the SceneDelegate isn’t, so the scheme can’t be used further. I assume the controller works fine, but the SceneDelegate can’t print anything.

We’ve tried many approaches, such as uninstalling & reinstalling the app, restarting Xcode, and appDelegate, but none of them have worked. I think this version is the closest one.

Question: How can we get the SceneDelegate’s methods working?

It’s taking us so long. If more information is needed, I’ll provide it immediately. Thank you!

SceneDelegate.swift

import SwiftUI

class SceneDelegate: UIResponder, UIWindowSceneDelegate {
    var window: UIWindow?

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        print("hahahah")
        guard let windowScene = scene as? UIWindowScene else { return }
        
        let contentView = ContentView()
        
        if let urlContext = connectionOptions.urlContexts.first {
            handleIncomingURL(urlContext.url)
        }

        let window = UIWindow(windowScene: windowScene)
        window.rootViewController = UIHostingController(rootView: contentView)
        self.window = window
        window.makeKeyAndVisible()
    }

    func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
        print("asdfasdf")
        if let urlContext = URLContexts.first {
            handleIncomingURL(urlContext.url)
        }
    }

    private func handleIncomingURL(_ url: URL) {
        print(url)

        guard url.scheme == "yanfudaoapp" else {
            return
        }

        if url.host == "openUrl" || url.host == "openPDF" {
            if let pdfURLString = url.queryParameters?["url"],
               let pdfURL = URL(string: pdfURLString) {
                if let hostingController = window?.rootViewController as? UIHostingController<ContentView> {
                    DispatchQueue.main.async {
                        print(pdfURL)
                        hostingController.rootView.handleIncomingURL(url: pdfURL)
                    }
                }
            }
        }
    }
}

We expect the SceneDelegate’s method to be called for processing scheme commands.
