# init(sources:selection:content:label:) Creates a picker that displays a custom label. ``` nonisolated init(sources: C, selection: KeyPath>, @ContentBuilder content: () -> Content, @ContentBuilder label: () -> Label) where C : RandomAccessCollection ``` ## Parameters `sources` A collection of values used as the source for displaying the Picker’s selection. `selection` The key path of the values that determines the currently-selected options. When a user selects an option from the picker, the values at the key path of all items in the `sources` collection are updated with the selected option. `content` A view that contains the set of options. `label` A view that describes the purpose of selecting an option. ## Discussion If the wrapped values of the collection passed to `sources` are not all the same, some styles render the selection in a mixed state. The specific presentation depends on the style. For example, a Picker with a menu style uses dashes instead of checkmarks to indicate the selected values. In the following example, a picker in a document inspector controls the thickness of borders for the currently-selected shapes, which can be of any number. ``` enum Thickness: String, CaseIterable, Identifiable { case thin case regular case thick var id: String { rawValue } } struct Border { var color: Color var thickness: Thickness } @State private var selectedObjectBorders = [ Border(color: .black, thickness: .thin), Border(color: .red, thickness: .thick) ] Picker( sources: $selectedObjectBorders, selection: \.thickness ) { ForEach(Thickness.allCases) { thickness in Text(thickness.rawValue) } } label: { Text("Border Thickness") } ``` --- Copyright © 2026 Apple Inc.
