Overview of this book

Over the last few years, we’ve seen a breakthrough in mobile computing and the birth of world-changing mobile apps. With a reputation as one of the most user-centric and developer-friendly platforms, iOS is the best place to launch your next great app idea. As the official tool to create iOS applications, Xcode is chock full of features aimed at making a developer’s job easier, faster, and more fun. This book will take you from complete novice to a published app developer, and covers every step in between. You’ll learn the basics of iOS application development by taking a guided tour through the Xcode software and Swift programming language, before putting that knowledge to use by building your first app called “Snippets.” Over the course of the book, you will continue to explore the many facets of iOS development in Xcode by adding new features to your app, integrating gestures and sensors, and even creating an Apple Watch companion app. You’ll also learn how to use the debugging tools, write unit tests, and optimize and distribute your app. By the time you make it to the end of this book, you will have successfully built and published your first iOS application.

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:
