Swift: filter requested endpoints by interface

[NotRealKomar]

Sometimes on connection, Swift server returns endpoints in the wrong order, so the client may use the admin endpoint instead of the public one, for instance.

     // Will take the first endpoint with no other checks
      _config.endpoints = _serviceCatalog.endpoints.find((element) => {
        return element.region?.toLowerCase() === _storage.region?.toLowerCase();
      });

That leads to forbidden errors in some cases.

The suggestion is to add an option to filter endpoints by their interface
