# App extensions Extend your app’s basic functionality to other parts of the system, like by adding a Widget. ## Overview Use SwiftUI along with to add widgets to your app.  Widgets provide quick access to relevant content from your app. Define a structure that conforms to the [`Widget`](/documentation/SwiftUI/Widget) protocol, and declare a view hierarchy for the widget. Configure the views inside the widget as you do other SwiftUI views, using view modifiers, including a few widget-specific modifiers. For design guidance, see in the Human Interface Guidelines. ## Topics ### Creating widgets [`protocol Widget`](/documentation/SwiftUI/Widget) The configuration and content of a widget to display on the Home screen or in Notification Center. [`protocol WidgetBundle`](/documentation/SwiftUI/WidgetBundle) A container used to expose multiple widgets from a single widget extension. [`struct LimitedAvailabilityConfiguration`](/documentation/SwiftUI/LimitedAvailabilityConfiguration) A type-erased widget configuration. [`protocol WidgetConfiguration`](/documentation/SwiftUI/WidgetConfiguration) A type that describes a widget’s content. [`struct EmptyWidgetConfiguration`](/documentation/SwiftUI/EmptyWidgetConfiguration) An empty widget configuration. ### Composing control widgets [`protocol ControlWidget`](/documentation/SwiftUI/ControlWidget) The configuration and content of a control widget to display in system spaces such as Control Center, the Lock Screen, and the Action Button. [`protocol ControlWidgetConfiguration`](/documentation/SwiftUI/ControlWidgetConfiguration) A type that describes a control widget’s content. [`struct EmptyControlWidgetConfiguration`](/documentation/SwiftUI/EmptyControlWidgetConfiguration) An empty control widget configuration. [`struct ControlWidgetConfigurationBuilder`](/documentation/SwiftUI/ControlWidgetConfigurationBuilder) A custom attribute that constructs a control widget’s body. [`protocol ControlWidgetTemplate`](/documentation/SwiftUI/ControlWidgetTemplate) A type that describes a control widget’s content. [`struct EmptyControlWidgetTemplate`](/documentation/SwiftUI/EmptyControlWidgetTemplate) An empty control widget template. [`struct ControlWidgetTemplateBuilder`](/documentation/SwiftUI/ControlWidgetTemplateBuilder) A custom attribute that constructs a control widget template’s body. [`func controlWidgetActionHint(_:)`](/documentation/SwiftUI/View/controlWidgetActionHint(_:)) The action hint of the control described by the modified label. [`func controlWidgetStatus(_:)`](/documentation/SwiftUI/View/controlWidgetStatus(_:)) The status of the control described by the modified label. ### Labeling a widget [`func widgetLabel(_:)`](/documentation/SwiftUI/View/widgetLabel(_:)) Returns a localized text label that displays additional content outside the accessory family widget’s main SwiftUI view. [`func widgetLabel(label: () -> Label) -> some View`](/documentation/SwiftUI/View/widgetLabel(label:)) Creates a label for displaying additional content outside an accessory family widget’s main SwiftUI view. ### Styling a widget group [`func accessoryWidgetGroupStyle(AccessoryWidgetGroupStyle) -> some View`](/documentation/SwiftUI/View/accessoryWidgetGroupStyle(_:)) The view modifier that can be applied to `AccessoryWidgetGroup` to specify the shape the three content views will be masked with. The value of `style` is set to `.automatic`, which is `.circular` by default. ### Controlling the accented group [`func widgetAccentable(Bool) -> some View`](/documentation/SwiftUI/View/widgetAccentable(_:)) Adds the view and all of its subviews to the accented group. ### Managing placement in the Dynamic Island [`func dynamicIsland(verticalPlacement: DynamicIslandExpandedRegionVerticalPlacement) -> some View`](/documentation/SwiftUI/View/dynamicIsland(verticalPlacement:)) Specifies the vertical placement for a view of an expanded Live Activity that appears in the Dynamic Island. --- Copyright © 2026 Apple Inc.
