RLMRealmConfiguration.seedFilePath is not copied in copyWithZone:

[adysart]

How frequently does the bug occur?

Always

Description

The seedFilePath property on RLMRealmConfiguration is not included when this type is copied in copyWithZone:. Since the configuration is copied when it is set as the default configuration, this means that it is not possible to set a seedFilePath on the default configuration.

The seedFilePath state is maintained in a property local to RLMRealmConfiguration:

realm-swift/Realm/RLMRealmConfiguration.mm

Line 185 in 95cb711

_seedFilePath = seedFilePath;

The copyWithZone: method does not include that state when copied:

realm-swift/Realm/RLMRealmConfiguration.mm

Lines 123 to 136 in 95cb711

	- (instancetype)copyWithZone:(NSZone *)zone {
	RLMRealmConfiguration *configuration = [[[self class] allocWithZone:zone] init];
	configuration->_config = _config;
	configuration->_cache = _cache;
	configuration->_dynamic = _dynamic;
	configuration->_migrationBlock = _migrationBlock;
	configuration->_shouldCompactOnLaunch = _shouldCompactOnLaunch;
	configuration->_customSchema = _customSchema;
	configuration->_eventConfiguration = _eventConfiguration;
	configuration->_migrationObjectClass = _migrationObjectClass;
	configuration->_initialSubscriptions = _initialSubscriptions;
	configuration->_rerunOnOpen = _rerunOnOpen;
	return configuration;
	}
