Answer 1

In my case i needed to first check ASAuthorizationPasswordProvider, then, if there are no stored credential, use ASAuthorizationAppleIDProvider. For this case i had to make some crunches. Code below:

// Initial point   
public func fire(appleIDCompletion: @escaping AppleIDServiceCompletion) {
    self.completion = appleIDCompletion

    let requestPassword = ASAuthorizationPasswordProvider().createRequest()
    performRequest(requestPassword)
}

// help function
private func performRequest(_ request: ASAuthorizationRequest) {
    let controller = ASAuthorizationController(authorizationRequests: [request])
    controller.delegate = self
    controller.presentationContextProvider = self
    controller.performRequests()
} 

// delegate
func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {
    if let e = error as? ASAuthorizationError {
        switch e.code {
        case .canceled:
            trace("User did cancel authorization.")
            return
        case .failed:
            trace("Authorization failed.")
        case .invalidResponse:
            trace("Authorization returned invalid response.")
        case .notHandled:
            trace("Authorization not handled.")
        case .unknown:
            if controller.authorizationRequests.contains(where: { $0 is ASAuthorizationPasswordRequest }) {
                trace("Unknown error with password auth, trying to request for appleID auth..")

                let requestAppleID = ASAuthorizationAppleIDProvider().createRequest()
                requestAppleID.requestedScopes = [.email, .fullName]
                requestAppleID.requestedOperation = .operationImplicit
                performRequest(requestAppleID)
                return
            } else {
                trace("Unknown error for appleID auth.")
            }
        default:
            trace("Unsupported error code.")
        }
    }

    completion?(.rejected(error))
}

Works like a charm
