just remove the parameter names instead of suppressing warnings

I don't see how this isn't strictly necessary? schema_version defaults to 0.

I think once the realm is opened it by RLMRealmWithConfiguration the default is applied. But since this config is only ever used to make a sharedRealm I think 1527 isn't needed for the assert on 1541 to pass. I could remove the comment, but either way would like to leave line 1527 in.

schemaVersion is set to 0 in RLMRealmConfiguration's initializer. The schema version is not used for anything though because there's no schema set, so this test will pass with the schema version set to any value.

Comments removed. Or do you think the whole lines could be removed since the schema isn't set?

I think it's maybe misleading to have it, since it's not actually being used? Not really a big deal either way.

This is the default and only needs to be set when it's being disabled.

You can avoid exposing these for testing by obtaining them via RLMSyncConfiguration:
RLMSyncConfiguration *syncConfig = [[RLMSyncConfiguration alloc] initWithRawConfig:{} path:""];
syncConfig.beforeClientReset = ^(RLMRealm *beforeFrozen) {
XCTAssertNotEqual(RLMNotVersioned, beforeFrozen->_realm->schema_version());
[beforeExpectation fulfill];
};
auto& beforeWrapper = syncConfig.rawConfiguration.notify_before_client_reset;
This makes the test a bit less coupled to the implementation details and avoids having to export the wrapper types.

Wow, thanks. This clears up a ton.

The realm namespace is for core and we shouldn't be defining things in it.

I don't see any reason for this to be a member function?

Are the xcode cloud swiftlint and docs errors "real"? |
It's possible for a realm with no schema version to experience a client reset. If this happens, the callback wrappers shouldn't be called. Otherwise a crash can occur at set_schema_subset in realmWithSharedRealm. From internal ticket 40981 and #8126
