Native Apple Sign with Tauri v1 + Swift

[rtiagom]

I'm trying to use AuthenticationServices framework with Tauri through swift-rs. I managed to have that working properly but ASAuthorizationController in Swift requires a Window to show the authorization model. I tried to use NSApplication.shared.windows.first but nothing happens on the Tauri side. Is there a way to pass the Tauri window to Swift? When I inspect NSApplication.shared.windows I see a reference to a TaoWindow <TaoWindow: 0x12ae09540>. Is this a reference to the main Tauri window? I might be approaching this completely wrong. Any help is appreciated.

Here's the Swift Package

import AuthenticationServices
import Foundation
import SwiftRs
import AppKit

class AppleSignInHandler: NSObject {
    public func startSignIn() {
        let request = ASAuthorizationAppleIDProvider().createRequest()
        request.requestedScopes = [.fullName, .email]
        
        let controller = ASAuthorizationController(authorizationRequests: [request])
        controller.delegate = self
        controller.presentationContextProvider = self
        controller.performRequests()
    }
}

@_cdecl("start_sign_in_tauri")
func startSignInTauri() {
    print("your message here")
    let appleSignInHandler = AppleSignInHandler()
    appleSignInHandler.startSignIn()
}

extension AppleSignInHandler: ASAuthorizationControllerDelegate {
    func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
        print("authorization controller");
        // Handle successful authorization
        if let appleIDCredential = authorization.credential as? ASAuthorizationAppleIDCredential {
            let userIdentifier = appleIDCredential.user
            let email = appleIDCredential.email ?? ""
            let fullName = appleIDCredential.fullName?.givenName ?? ""

            print("User ID: \(userIdentifier)")
            print("Email: \(email)")
            print("Full Name: \(fullName)")
        }
    }
    
    func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {
        // Handle authorization error
        print("Authorization error: \(error.localizedDescription)")
    }
}

extension AppleSignInHandler: ASAuthorizationControllerPresentationContextProviding {
    func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
        print("presentation context provider")
        print(NSApplication.shared.windows)
        // Return the window or view controller where you want the authorization window to appear
        return NSApplication.shared.windows.first!
    }
}
