Getting Started with the List

When I started doing iOS development, I first worked with Table Views. At the time, Collection Views hadn't been introduced yet. As you progress in iOS development, you will work with a lot of Table and Collection Views. You'll begin with just the basics to allow you to use them, and then you'll slowly progress into more advanced Table and Collection Views.
The reason that I bring this up is that, by the end of this chapter, you may feel as though things are not clicking. This is perfectly normal. However, the more you go through the steps in these chapters, the more they will become second nature to you.
For those of you who've not done iOS development, Table Views are great for presenting a list of data. The iPhone's Mail app is an example of a Table View.
In this chapter, we are going to work with our first Table View. In our Let's Eat app, users select a specific location to look for restaurants.
In this chapter, we will cover the following topics:
  • Understanding Table Views
  • Creating our first property list (plist)
  • Creating our location data manager
  • Cleaning up our file structure

Understanding Table Views

The first thing we want to do is get access to all of the UI and Playgrounds' components that we will need. At the very top of the playground, please add the following two import statements:
import UIKit
import PlaygroundSupport
The first import statement imports all of the UI elements we will need. The second import gives us access to Playgrounds support; this will allow us to add our UI elements into Playgrounds. Now, let's create our first UIViewController. This setup is pretty much the same structure I like to use for all of my classes that are controllers. Add a line break and then add the following code:
class TableViewExampleController: UIViewController {

This code looks pretty similar to what we did in the last chapter. We created a class named TableViewExampleController and we subclassed UIViewController. Next, we need to create a UITableView and an array of data to display in our tableView. Let's do that next by adding the following inside of our curly braces:
var tableView:UITableView?
var names:[String] = ["Deanna","Corliss","Deyvn"]
After you add the variable, your complete code should look like the following:
class TableViewExampleController: UIViewController {
var tableView:UITableView?
var names:[String] = ["Deanna","Corliss","Deyvn"]
This is the variable we will use for our UITableView. Here, we have an array with three names. The next thing we should do is c...
