InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
However this library works as long as you subclass DBModel for all your model objects.
It's one of the only guides/books that take into account modern and practical Core Data. One of the best books on the subject. objc.io also hase a quite good book (https://www.objc.io/books/core-data/) but it's a bit older not 100% current.
