Group in SwiftUI

Group in SwiftUI is a type that collects multiple instances of a content type — like views, scenes, or commands — into a single unit. Group doesn’t have any visual representation, its just a container much like VStack and HStack.

We use a group to collect multiple views into a single instance, without affecting the layout of those views, just like an HStack, VStack, or Section . After creating a group, any modifier applied to the group affects all of that group’s members.

Let’s start with example.

struct DevTechieGroupExample: View {
    var body: some View {
        VStack {
            Text("DevTechie Courses")
                .font(.largeTitle)
            Group {
                Text("SwiftUI")
                Text("Combine")
                Text("iOS Development")
            }.font(.body)
        }
    }
}

Because we create a group of views with a ViewBuilder, we can use the group’s initializer to produce different kinds of views from a conditional, and then optionally apply modifiers to them.

The following example uses a Group to add a navigation bar title, regardless of the type of view the conditional produces.

struct DevTechieGroupExample: View {
    @State private var loggedIn = true
    var body: some View {
        NavigationView {
            Group {
                if…
