# init(sources:isOn:label:) Creates a toggle representing a collection of values with a custom label. ``` nonisolated init(sources: C, isOn: KeyPath>, @ContentBuilder label: () -> Label) where C : RandomAccessCollection ``` ## Parameters `sources` A collection of values used as the source for rendering the Toggle’s state. `isOn` The key path of the values that determines whether the toggle is on, mixed or off. `label` A view that describes the purpose of the toggle. ## Discussion The following example creates a single toggle that represents the state of multiple alarms: ``` struct Alarm: Hashable, Identifiable { var id = UUID() var isOn = false var name = "" } @State private var alarms = [ Alarm(isOn: true, name: "Morning"), Alarm(isOn: false, name: "Evening") ] Toggle(sources: $alarms, isOn: \.isOn) { Text("Enable all alarms") } ``` --- Copyright © 2026 Apple Inc.
