Less code, more flow. Let's dance!

  assert(fittingDef.url, util.format('url is required on fitting: %j', fittingDef));

  var client = require('swagger-client');
  var swagger = new client.SwaggerClient({

    success: function() {
      debug('swaggerjs initialized');
    },
    failure: function(err) {
      console.log('swaggerjs', err); // todo: what?
    },
    progress: function(msg) {
      debug('swaggerjs', msg);
    }
  });
  swagger.build();

  return function(context, next) {
