ASAuthorizationController issue when working with multiple requests

Question

So, here's the issue:

If I have both email-password and apple id records in my keychain for an app, and want to request that data to do auto-login, I can get email-password based accounts info fine.

Apple ID does not work as expected though. I receive ASAuthorizationAppleIDCredential object with authorizationCode == nil. I do receive credential.identityToken and can decode the token. It's a valid one, but the thing is that I need authorizationCode.

If I use stand-alone login function of AppleAuthenticator, it works correctly. ASAuthorizationController executes performRequests perfectly and I can get authorizationCode from ASAuthorizationAppleIDCredential. The issue is with AggregatedAuthenticator. It seems that ASAuthorizationController is sort of broken and cannot get all the data if there's more than one request passed to it.

AggregatedAuthenticator(anchor: view.window!).startAutoLogin() // does not work with apple id

but

AppleAuthenticator(anchor: view.window!).login() // works

The only difference is that AppleAuthenticator uses only one request in ASAuthorizationController.

The only workaround that I could come up with is if I go to AggregatedAuthenticator and do the login again there, see the comment in code:

public func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
    switch authorization.credential {
    case let appleIDCredential as ASAuthorizationAppleIDCredential:
        // Question: here we receive the credential without authorizationCode, but why?
        appleAuthenticator.login(with: appleIDCredential)
        // BUT if I do:
        // appleAuthenticator.login()
        // it works fine, but it shows that bottom sheet again asking for your face/touch-id again, but only for apple id this time
    case let emailPasswordPair as ASPasswordCredential:
        emailAuthenticator.login(with: emailPasswordPair)
    default:
        print("Irrelevant stuff")
    }
}

Any ideas, folks?

Alright, folks, it's an iOS 15 regression. Everything used to work before.
