In these bonus lessons, let's walk through how to setup a simple messaging system for the matched users in our Firestore database. Before I set up the data structure for how to store our objects in the database, I almost always prefer to build out the screens first. I do this for a couple of reasons, but mostly its to make sure I can wrap my head around what relationships are need among each entity. To make this process faster, and also because I'm confident most of you guys already know how to build a list, I'll be utilizing LBTATools to speed this up.
