@resultBuilder struct ControlWidgetTemplateBuilder

A custom attribute that constructs a control widget template's body. The `@ControlWidgetTemplateBuilder` attribute allows your control template's body closure to produce a control template after zero or more other statements: struct GarageDoorOpener: ControlWidget { var body: some ControlWidgetConfiguration { let kind = "com.yourcompany.GarageDoorOpener" StaticControlConfiguration( kind: kind ) { let isOpen = ... ControlWidgetToggle( "Garage Door", isOn: isOpen, action: ToggleGarageDoor() ) { Label( $0 ? "Open" : "Closed", systemImage: $0 ? "door.garage.open" : "door.garage.closed" ) } } } }
