Populate TableView using URLSession & JSONDecoder in 4 Steps

Michael Miles demonstrates how to fetch data from a REST API using URLSession, decode it with JSONDecoder, and display it in a UITableView.

Hey! In this video, we fill out a TableView using the PokeAPI found at pokeapi.co. To do this, we use URLSession and the JSON Decoder. We also update the TableView with the data, which can be kind of tricky to time properly, so we use the DispatchQueue and booleans to control the data flow for us.
