Completion Handlers

In this video I am going to explore CompletionHandlers. What are they? How can we create them, and how to use them. They are a fundamental concept in programming and are often referred to as callbacks.
As we proceed, we will also learn about escaping completion blocks, and trailing closures.
We will start with a playground as an introduction to develop the concept and end up with looking at a simple iPhone app to reinforce our learning.
