In the app that I'm working on I have been previously using CoreData, and now I am migrating all my CoreData logic to CoreStore. I have some convenience initializers for my CoreData objects as such;

convenience init(fromJson json: JSON) {
        self.init()
        self.addData(fromJson: json)
    }

I was wondering if it is possible to use these initializers with create(_ into) ? Since creating the object with those initializers and then using fetchExisting on the transaction doesn't seem to work.

Unlike Core Data, CoreStore doesn't allow orphaned objects that do not belong to any store. Instead I would suggest to use the Importing API using ImportableObject or ImportableUniqueObject protocols and use the transaction.import***(...) methods instead.
