Snippet dates

Our last story is a pretty simple one: "I want to see the date a snippet was made". To do this, we're going to have to accomplish the following tasks:

• Appending our base SnippetData to hold a date

• When a snippet is created, saving the current date to our data model

• Adding a UILabel to our prototype cells to hold date information, and assign the text in our view controller

This should be a fairly straightforward feature to add, especially since we set up the rest of our code pretty neatly. Let's get to it.

Update SnippetData model

Current task: Append our base SnippetData to hold a date.

First, let's make a quick update to our data model, in SnippetData.swift. In our base class of SnippetData, we want to add a new property called date, of the type Date. We then also need to update all of our initializers to accept a value for the date, and we then assign that date to our date property. Here is the updated source code for our data model, with the changed lines highlighted:
