How to add a toolbar to the keyboard

SwiftUI lets us add input accessory views to keyboards, which means that when the user activates some text entry we can present custom buttons there.

This is all done using by attaching the toolbar() modifier to whatever view should own the input accessory. When creating your toolbar item group, use a placement of .keyboard to attach this toolbar to the keyboard, like this:

struct ContentView: View {
    @State private var name = "Taylor"

    var body: some View {
        TextField("Enter your name", text: $name)
            .textFieldStyle(.roundedBorder)
            .toolbar {
                ToolbarItemGroup(placement: .keyboard) {
                    Button("Click me!") {
                        print("Clicked")
                    }
                }
            }
    }
}

A text field, below which is iOS's software keyboard. Above the keyboard is a grey row containing the words “Click me!” in blue.

Important: In Xcode 13 beta 1 this requires a NavigationView to work.

In practice this is a great place to use something like @FocusState to move between input fields in your UI, or to hide the keyboard altogether, like this:

struct ContentView: View {
    @State private var name = "Taylor Swift"
    @FocusState var isInputActive: Bool

    var body: some View {
        NavigationView {
            TextField("Enter your name", text: $name)
                .textFieldStyle(.roundedBorder)
                .focused($isInputActive)
                .toolbar {
                    ToolbarItemGroup(placement: .keyboard) {
                        Spacer()

                        Button("Done") {
                            isInputActive = false
                        }
                    }
                }
        }
    }
}
