SwiftUI Reference

What is SwiftUI

SwiftUI is a declarative UI framework that allows developers to design apps across all Apple platforms.

The Starter SwiftUI Document

import SwiftUI

struct ContentView : View {
var body: some View {
Text(“Hello World”)
}
}

#if DEBUG
struct ContentView_Previews : PreviewProvider {
static var previews: some View {
ContentView()
}
}
#endif

Example Explained

Swift UI components are the foundation of the framework.

SwiftUI Components

import SwiftUI – References the SwiftUI module for use in the code
struct ContentView : Views – Creates a new class
var body: some View – Creates a subclass of View
Text() – Defines the Text that will be displayed

#if DEBUG – Specifies to the compiler what content to preview
struct ContentView_Previews – Initiates the preview class
static var previews: – Specifies the content to preview
ContentView() – Specifies the class that will be previewed
#endif – Specifies the end of the content to be previewed
