// let postLogoutRedirectURL = URL(string: "com.example.app:/logout")!

OIDAuthState.authState(byPresenting: request, presenting: self) { authState, error in
  // Store authState?.lastTokenResponse?.accessToken
}

// Logout uses the validated ID token retained in AuthState.
OIDAuthorizationService.discoverConfiguration(
  forIssuer: URL(string: "https://{tenant}.id.tuurio.com")!
) { config, _ in
  guard let config = config else { return }
  let endSession = OIDEndSessionRequest(
    configuration: config,

    postLogoutRedirectURL: URL(string: "com.example.app:/logout")!,

  self.present(OIDAuthorizationService.present(endSession, presenting: self) { _, _ in }, animated: true)
}
                        

Suggerimento: anche iOS AppAuth supporta discovery per caricare automaticamente la configurazione.
