Preface
In this book, we will build a Restaurant Reservation app called Let's Eat. We will start the book off by exploring Xcode, our programming environment, which is also known as Interface Development Environment (IDE). Next, you will start learning the foundations of Swift, the programming language used in iOS apps. Once we are comfortable with the basics of Swift, we will dig deeper to build a more solid foundation.
After we have a solid foundation of using Swift, we will start creating the visual aspects of our Let's Eat app. During this process, we will work with storyboards and connect our apps structure together using segues. With our UI complete, we will go over the different ways that we can display data. To display our data in a grid, we will use Collection Views, and to display our data in a list, we will use Table Views.
We will also look at how to add basic and custom annotations on to a map. Finally, it's time to get real data; we will look at what an Application Programming Interface (API) is and how we can get real restaurant data into our Collection Views, Table Views, and Map.
We now have a complete app, but what about adding some bells and whistles? The first place we can add a feature will be on the restaurant detail page where we can add restaurant reviews. Here, users will be able to take or choose a picture and apply a filter on to their picture. They will also be able to give the restaurant a rating as well as a review. When they are done, we will save this data using Core Data.
Since we built our app to work on both iPhone and iPad, we should add the ability to make our app support iPad Multitasking. Doing this will allow our app to be open alongside another app at the same time.
If we want to be able to send our reservation to a friend, we can create a custom UI for iMessages, that will send them the details for the reservation along with the app it came from. The one thing missing from our app is the ability to notify the user with a custom notification to alert when they have an upcoming reservation.
Finally, let's create some quick access for our app using 3D touch, where by tapping our app icon, the user can quickly jump to their reservations. Now that we have added some bells and whistles, let's get this app to our friends using TestFlight, and finally get it into the App Store.
What this book covers
Chapter 1, Getting Familiar with Xcode, will take us through a tour of Xcode and talk about all of the different panels we will use throughout the book.
Chapter 2, Building a Foundation with Swift, deals with the basics of Swift.
Chapter 3, Digging Deeper, teaches us to build on our Swift foundation and learn some more basics of Swift.
Chapter 4, Digging into Collections, will talk about the different types of Collections.
Chapter 5, Starting the UI Setup, is about building the Let's Eat app. We will focus on getting our structure setup using storyboards.
Chapter 6, Setting Up UI, deals with working on our Let's Eat app in a storyboard.
Chapter 7, Getting Started with the Grid, is about working with Collection Views and how we can use them to display a grid of items.
Chapter 8, Getting Started with the List, teaches us to work with Table View and takes a deep look at dynamic Table Views.
Chapter 9, Working More with Lists, will talk about working with Table Views, but we will look at static Table Views.
Chapter 10, Where Are We?, deals with working with MapKit and learning how to add annotations to a map. We will also create custom annotations for our map.
Chapter 11, Where's My Data?, is about learning how to use a JSON API within our app.
Chapter 12, Foodie Reviews, talks about working with the phone's camera and library. We will then look at how to apply filters to our photos.
Chapter 13, Saving Reviews, wraps up Reviews by saving them using Core Data.
Chapter 14, Universal, deals with multitasking on the iPad, and how we can get an update to be supported on all devices.
Chapter 15, iMessages, is about building a custom message app UI. We will also create a framework to share data between both apps.
Chapter 16, Notifications, provides learning on how to build basic notifications. Then, we will look at embedding images into our notifications as well as building a custom UI.
Chapter 17, Just a Peek, looks at 3D touch and how to add quick actions to our app. We will also look at how we can add peek and pop to our restaurant list.
Chapter 18, Beta and Store Submission, is about how to submit apps for testing as well as submitting apps to the App Store.

Conventions
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You can add comments to your code, such as a TODO item or just a brief explanation of what something is doing."
A block of code is set as follows:
let arrOfInts:[Int] = [] let arrStrings = [String]()
