Hi,
can anyone tell me, does CoreStore supports batch requests? I need write multiple changes into database on existing data, but I can't find good solution for this problem.

For example NSBatchUpdateRequest seems like this:
let batchRequest = NSBatchUpdateRequest(entityName: "SomeEntity") batchRequest.propertiesToUpdate = ["status": PointType.new.rawValue] batchRequest.resultType = .updatedObjectIDsResultType

Hi, batch requests are currently not yet implemented, sorry.
You should still be able to do this manually within transactions:

CoreStore.perform(
    asynchronous: { (transaction) in

        let batchRequest = NSBatchUpdateRequest(
            entity: CoreStore.defaultStack.entityDescription(for: YourEntity.self)!
        )
        batchRequest.propertiesToUpdate = ["status": PointType.new.rawValue]
        batchRequest.resultType = .updatedObjectIDsResultType
        try transaction.unsafeContext().execute(batchRequest)
    },
    completion: { _ in /* ... */ }
)
