moreBefore You Begin
This section tells you a few things you need to know before you get started, such as what you’ll need for hardware and software, where to find the project files for this book, and more.
Section I: Your First App: HIITFit
At WWDC 2019, Apple surprised and delighted the developer community with the introduction of SwiftUI, a declarative way of building user interfaces. With SwiftUI, you build your user interface by combining fundamental components such as colors, buttons, text labels, lists and more into beautiful and functional views. Your views react to changes in the data they display, updating automatically without any intervention from you!
In this section, you’ll begin your journey to becoming a SwiftUI developer by developing an app called HIITFit, a High Intensity Interval Training Fitness tracker. Along the way, you’ll:
- Learn how to use Xcode.
- Discover how to plan and prototype an app.
- Explore the basic components of SwiftUI.
- Understand how data moves in a SwiftUI app and how to make it persist.
- Learn fundamental concepts of Swift, the programming language, needed to build your app.
Section II: Your Second App: Cards
Now that you’ve completed your first app, it’s time to apply your knowledge and build a new app from scratch. In this section, you’ll build a photo collage app called Cards and you’ll start from a blank template. Along the way, you’ll:
- Dive more deeply into Swift’s ways of representing data.
- Learn how to support user gestures.
- Discover how Xcode and iOS manage app assets such as images and colors.
- Explore more robust ways of saving and restoring data.
- Translate a designer’s vision into reality in your app.
Section III: Your Third App: TheMet
You’ve now built two apps with beautiful user interfaces. But, you’re probably wondering how to build an app that accesses resources on the internet. Fear not! In this section, you’ll build TheMet, an app that allows you to view items in the collection at the Metropolitan Museum of Art — better known as The Met. Along the way, you’ll:
- Learn how to build lists of information and navigate between views using SwiftUI.
- Discover the intricacies of REST APIs and how to use them.
- Explore iOS’s networking support using a Swift Playground.
- Learn to how add support for iOS Widgets to your app.
