SwiftUI macOS SignInWithAppleButton in

so was there any Feedback on this?

I got to meet with some Apple Engineers at WWDC22. They suggested to create a UIViewRepresentable that is a wrapper around the ASAuthorizationAppleIDButton.

Then hook it up to a ASAuthorizationController and set the presentationContextProvider.

    let request = ASAuthorizationAppleIDProvider().createRequest()
    request.requestedScopes = [.fullName, .email]
    let controller = ASAuthorizationController(authorizationRequests: [request])
    controller.delegate = self
    controller.presentationContextProvider = self
    controller.performRequests()

And then on the presentationContextProvider protocol implementation provide the proper key window to use for popup presentation.

 public func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
    let keyWindow = (UIApplication.shared.connectedScenes.first?.delegate as? SceneDelegate)?.window
    return keyWindow ?? ASPresentationAnchor()
  }

That's what I tried. I used this example as my template for creating the SwiftUI wrapper button and a coordinator. SiwaButton.swift
