To Reproduce

• (void)parseResultAndUpdateWithName:(NSString *)name data:(NSData *)data error:(NSError *__autoreleasing *)error {
  NSError *parseError;
  NSArray *registrations = [SBRegistrationParser parseRegistrations:data error:&parseError];
  if (!parseError) {
  //When we getting nil array that time we found crashed
  *[storageManager updateWithRegistrationName:name registration:(SBRegistration )[registrations objectAtIndex:0]];
  } else if (error) {
  (*error) = parseError;
  }
  }

  //When we getting nil array that time we found crashed
  *[storageManager updateWithRegistrationName:name registration:(SBRegistration )[registrations objectAtIndex:0]];
  } else if (error) {
  (*error) = parseError;
  }
  }
