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.
If you take a look at the examples in the RxSwift repo, in the repo for objc.io's App Architecute book, and in Artsy's eidolon app you'll see view models implemented as classes. I think it fairly safe to say that Krunoslav Zaher (top contributor to RxSwift), Florian Kugler, and Ash Furrow know how to use MVVM and RxSwift properly.
