Chapter 1
Introducing SwiftUI
IN THIS CHAPTER
I know the feeling of being on the verge of learning something new. If youâre anything like me, youâre eager to try things out and see how it feels. And thatâs exactly what you do in this chapter!
In this chapter, I explain what SwiftUI is, show you how SwiftUI has changed the user interface (UI) development paradigm, and explain how SwiftUI makes the process easier going forward. Then I tell you how you can get started with the necessary tools. Finally, with the tools that youâve installed, you create your first iOS application using SwiftUI, and learn how the various components in your project work together as a whole.
Understanding What SwiftUI Is
SwiftUI is a declarative programming framework for developing UIs for iOS, iPadOS, watchOS, tvOS, and macOS applications. In fact, SwiftUI was invented by the watchOS group at Apple.
Before SwiftUI was introduced, most developers used UIKit and Storyboard (which is still supported by Apple in the current version of Xcode, as of this writing [version 11.4.1]) to design a UI. Using UIKit and Storyboard, developers drag and drop View controls onto View Controllers and connect them to outlets and actions on the View Controller classes. This model of building UIs is known as Model View Controller (MVC), which creates a clean separation between UI and business logic.
The following shows a simple implementation in UIKit and Storyboard. Here, a
Button and Label view have been added to the View Controller in Storyboard; two outlets and an action have been created to connect to them: class ViewController: UIViewController { @IBOutlet weak var lbl: UILabel! @IBOutlet weak var button: UIButton! @IBAction func btnClicked(_ sender: Any) { lbl.text = "Button tapped" }For laying out the views, you use auto-layout to position the button and label in the...
