SwiftUI’s Group Box feature presents a sophisticated approach to assembling related views. Notably, it incorporates a default style characterized by a background with gently rounded corners. The tutorial will guide you through creating Group Boxes with both standard and customized designs. It’s tailored for iOS14 and Xcode 12 users, accessible through the Apple developer portal.

Setting Up the Development Environment

Begin by launching Xcode. You can either create a new Xcode project from the startup window or navigate through File > New > Project. Select ‘iOS’ as your target platform and opt for the ‘App’ template under the Application section before proceeding.

After entering “SwiftUIGroupBoxTutorial” as the Product Name, ensure you select SwiftUI for both Interface and Life Cycle and Swift as the programming language. Uncheck the ‘Include Tests’ option, then proceed to select a directory on your Mac for saving the project.

Implementing a Basic Group Box

In this section, you’ll learn to create a basic Group Box with a built-in text label. The code snippet demonstrates how to implement a Group Box containing a heart rate indicator:

struct ContentView: View {    @State private var name = “”
    var body: some View {        VStack {            GroupBox(label: Label(“Heart rate”, systemImage: “heart.fill”).font(.largeTitle)) {                Text(“69 BPM”).font(.title)            }            Spacer()        }.padding(.horizontal)    }}

Customizing Group Box Styles

SwiftUI’s Group Box also allows for customization beyond the default label. This can be achieved by excluding the pre-built label, offering flexibility in styling:

GroupBox {    Text(“Enter your name”).font(.title)    TextField(“name”, text: $name)}

Previewing and Testing

Utilize the Preview feature in Xcode to observe the different appearances of the two Group Box styles. This step ensures that the visual elements align with your design intentions.
