How to create grouped and inset grouped lists

Paul Hudson    @twostraws   

Updated for Xcode 13.0

Updated for iOS 15

SwiftUI’s List views have a listStyle() modifier to control how the list looks, and there are two options you’re likely to want: .grouped (or GroupedListStyle() for Xcode 12) to get the old-style grouping of items, and .insetGrouped (or InsetGroupedListStyle() for Xcode 12) to get the newer style grouping of items.

For example, this defines an example row and places it inside a grouped list:

struct ExampleRow: View {
    var body: some View {
        Text("Example Row")
    }
}

struct ContentView: View {
    var body: some View {
        List {
            Section(header: Text("Examples")) {
                ExampleRow()
                ExampleRow()
                ExampleRow()
            }
        }
        .listStyle(.grouped)
    }
}

Download this as an Xcode project

A group of 3 rows whose width spans the screen below an “Examples” section heading.

Alternatively, this will create a list of 100 rows with the new inset style of grouping:

List(0..<100) { i in
    Text("Row \(i)")
}
.listStyle(.insetGrouped)

Download this as an Xcode project

A group of rows with left and right edges inset from the screen's sides.

Important: If you’re using Xcode 12 you need to use GroupedListStyle and InsetGroupedListStyle() rather than .grouped and insetGrouped.
