App state with Realm and RxSwift

Intro This post isn’t that much about operators but how to leverage the awesome technology that Realm is. Long story short - I wanted to submit an app for review and literally just before hitting submit I realized I forgot to implement a favorites filter in one of the view controllers. I would’ve quickly hacked something to send it off but since different controllers took care of the navigation bar and the actual table view showing the data could not hack my way around.
