I have an application for macOS written in Swift using Realm for persistence and to this point, the app only used resources included in the bundle. However, I’d like to included a lessons page that would check a web service to see if new lessons are available and if so, download and import them into my app. The lessons are simple classes with a few properties and references to a couple of assets, such as a video and audio files, which would also need to be pulled from the web service. I don’t need any user information posted to the service, so communication would be one-way.

I’ve looked into Vapor, RealmSync, and Firebase, but all the use-cases seem much more complex than I need. I’m looking for the cheapest, easiest, simplest solution for this small-scale project and would greatly appreciate some guidance getting started.
